Thanks all

Apparantly you are as old as the woman you feel.....which is a bit of an issue in my case  :-X

Depends if you have monoggamous hands or not.

Maintenance Guides / Ignition switch and connector removal
« on: 02 November 2008, 21:00:26 »
[size=12]To remove connector from ignition switch:[/size]

Disconnect battery
Turn ignition key to position '1'
Insert a small screwdriver into the connector release hole, keeping the screwdriver at the key end of the hole,  and press to release the latch, at the same time as pulling / levering the connector off the switch. It is a tight fit but if it doesnt move you havnt deprssed the latch enough or have pressed on the wrong part of the latch.


To remove switch:
With key in position '1', push a welding rod or allen key into the barrel release hole and remove the lock barrel.

Now remove the switch fixing screw and the connector should move towards you slightly and come away. Do not simply try levering the switch off with the barrel still in place, you will distort the hole for the other holding pin at the back of the switch.

Maintenance Guides / Ignition lock re-condition
« on: 02 November 2008, 20:29:31 »
If you have problems with the ignition key refusing to turn occasionally then follow this guide to re-condition the lock cylinder before it sticks completely....you must be able to turn the key to get the cylinder out so dont leave it too late.

First remove the steering column shrouds (3 screws from underneath, two more visible with steering wheel turned through 90 degrees).
Now turn the key to position '1' (key is in-line with the largest of the two notches on the face of the key hole).
Push a piece of welding rod or a 3mm allen key into the lock barrel release hole and the barrel should spring out.



Look at the end of the lock barrel and turn the key to the START position, there is a spring-loaded pin which is acting as a rotation stop, press in this pin and turn the key further but do not let the pin fly out,

remove the pin and gently pull the lock cylinder out of the barrel, keeping the key in place.


Make a sketch of the lock cylinder then gently remove the key whilst keeping your fingers on the brass levers, we dont want any of them or their springs flying off into a spider infested corner somewhere.

Take out the brass levers one by one and lay them on your sketch, there is a number on each lever, write this on your sketch against the corresponding position to help with re-assembly.
Ease out the tiny lever springs, take care not to stretch them and try to keep them separated or they will lock together.


Wash all parts in parrafin or turps to remove old grease and dirt.
Look at the levers, if there are burrs on them then rub them gently on a fine oilstone.

Smear each lever with a tiny bit of grease then fit back into the correct slot, together with its spring.
Once all the levers are in place, press them flush with the cylinder and insert the key. If you have got the levers back in the right places they will be flush with the cylinder.

Put the cylinder back into the barrel and replace the spring loaded pin. Check that the key is free to turn then replace the barrel back into the steering lock. If the steering lock has engaged the barrel wont go in, look into the barrel chamber and there is a steel plate at the bottom of the chamber, use a screwdriver to slide this down until it latches then re-fit the barrel.

The door and boot lock cylinders can be dismantled and cleaned in a similar manner, the estate tailgate locks seem prone to collecting fine road dust which causes them to jam so these benefit from cleaning if begining to get stiff.

Maintenance Guides / Autobox to Manual Conversion Part 2
« on: 13 August 2008, 15:41:32 »
This is the finished wiring diagram:



When fitting brake or clutch switches you get much better access if you undo the relay or fuse panels, just remove the screws and the hinge part will pull off the fascia panel.
To remove a switch, hold the pedal down and pull out the switch plunger fully. Then pull out the locking sleeve (red in the photo), now press in the two locking tabs and withdraw the switch. The locking sleeve must be fully out as the photo otherwise you will break the locking tabs when you try to press them in.


To fit a switch, look at the hole in the mounting bracket, there is a notch in one corner, this matches a tab on the switch:

Click the switch into place, press in the locking sleeve fully (a green plastic bit will fall out of a new switch at this point. Gently let the pedal come up which will auto-adjust the switch operating point.

Maintenance Guides / Autobox to Manual Conversion
« on: 13 August 2008, 14:33:01 »
I will assume that if you are thinking of doing this then you must be a fairly competent mechanic so this will not be a complete step by step guide.

Parts Required

From the donor car:

Gearbox with rear cross-member and exhaust support
Differential (not essential---work out the ratios)
Front propshaft section (with vibration damper if present)
Clutch cover and driven plate
Flywheel and bolts
Clutch master cylinder and clutch pedal assy. Do not shorten the feed pipe from reservoir….you need every mm.
Plastic clip securing clutch pipe union to bulkhead
Brake pedal. Note only the pedal is needed, just push out the pivot pin.
Gear lever assy (drill off the rivet heads)
Piece of plastic trim just behind gear lever
Clutch pedal switch (will be on pedal assy if donor has cruise, get connector and wire)
Brake pedal switch and connector (not needed if car already has cruise 4-pin switch)
Section of gearbox/lambda sensor wiring loom

From main dealer:

Spigot needle bearing    90105743  
Spigot nylon bush          9157141


Procedure

With front wheels on ramps and rears raised on axle stands. (Chock front wheels securely or use ratchet straps from wheel to ramp) Raising the rear improves access to the exhaust bolts and centre propshaft joint.

Follow the Haynes manual if unsure but:
Unbolt propshaft then remove front section by tugging sharply off rear section
Unbolt torque convertor from flexplate and remove with gearbox
Unbolt flexplate from crank and remove adaptor ring from crank
Remove centre console then drill off rivet heads fixing gear selector to tunnel

Fit nylon spigot bush into bore in end of crank then gently tap in the needle bearing using a suitable socket.
Fit flywheel and torque the bolts…The crank must not be allowed to turn ‘backwards’ when doing this or the cambelt may slip on its sprockets.
Fit the clutch and centralise. This can be done by eye…visibility is good.

Fit gear lever assy to tunnel and make sure the rubber seal fits correctly then Pop Rivet in place
Check the bellhousing dowels are in the correct places then fit gearbox to engine. Use Locktite on the gearbox crossmember bolts

Look carefully at the rear propshaft splines, there is one wide ‘master’ spline. Locate the corresponding gap on the new front propshaft section and join the two halves. Grease the splines first.

Swap the brake pedals
Remove rubber bung from bulkhead then fit clutch master cylinder, it will fit in without loosening the servo with a bit of wriggling, scuttle has to be removed for access. Bolt on the clutch pedal assy, don’t forget the third bolt high up.
NB the metal clutch pipe fits between the two heater pipes. Fit clutch pipe plastic clip in place on the bulkhead. See pic for pipe route and position of retaining clip.


Drain the master cylinder header with a syringe then cut off the crimped pipe end with a stanley knife and connect the flexi hose with a jubilee clip. Refill the header and allow fluid to drain out via the clutch bleed nipple to flush the old fluid and debris out. Bleed from the bottom up using a pressure feed….no other method works properly.

This is my improvised pressure bleed kit made from an old eezi bleed, the green plastic pipe is a tight fit onto the clutch bleed nipple, fill bottle with hydraulic fluid, open bleed nipple, connect bottle to spare wheel (Max 10psi...otherwise you will get very wet very quickly!!). Allow fluid to flow into the nipple until the (previously empty) reservoir is full then close bleed nipple and test clutch operation.


Electrical

Cut off the auto selector switch connector.
 Starter inhibit
 Join the two thick Bk/R wires by soldering.
 Reverse Lights
 Separate the reverse switch wires from the donor loom and solder one side to the Bk wire (was on   pin D) solder the other side to the W/Bk wire (was on pin F)
 Lambda sensors
Plug-in the Lambda sensors, the auto loom is a bit short so move the connector fixing clips and tyrap the loom in place clear of hot bits. Tie up unused connectors and loom ends.

Ignition Timing Retard
Unplug the engine ECU and remove the connector from its hood (1 screw)
Locate the Bk/R wire on pin 42, cut off as far from pin 42 as possible (can do this further up the loom if preferred) then solder to one of the thin Brown wires and tape joint.

Cruise Control
Auto is not wired as shown in Haynes. My 99 was wired as follows:


For safety reasons the cruise has 3 separate circuits which can turn it off, to preserve this on an ex-auto car requires a bit of re-wiring to bring it in line with the manual box wiring.
Identify the Bk/R and Bk/Bu wires from the Brake switch cruise contacts, cut these and crimp together where they leave the main loom.
Remove the autobox ecu from the kick space by drivers foot and discard. Take cover off connector and identify the Bk/Y wire on pin 37. Cut at connector pin and free wire from the loom, pulling it back to the pedal area. Join this wire to the Bk/Bu from cruise brake switch.
Join the Bk/R from cruise brake switch to one wire from clutch switch.
Unscrew fuse box and pull down, find a thin Black wire going to F15, tap into this and connect to the remaining wire from clutch switch.

Re-tape any parts of the loom where you cut the fabric binding and replace any tyraps. Tyrap the auto ecu connector to the ecu mounting bracket. Make sure nothing can get caught on the pedals or throttle cable.

Maintenance Guides / How to disconnect heater hoses
« on: 31 July 2007, 15:10:35 »


The photo should help you understand what is lurking in the hard-to-reach corner of your engine bay.

To remove a connector:
       Press-in the latch and pull the locking ring back towards you ( the pic shows the locking ring in the fully-back position).
       Twist the whole connector assembly to un-stick the internal seals from the heater.
       Pull the connector and hose off the heater.


To replace a connector:
       Apply universal lubricant (spit) to the metal heater pipe.
       Push the connector onto the pipe and make sure it is fully home.
       Slide the locking ring away from you until it clicks into place. (if the locking ring wont move you probably havnt pushed the connector onto the heater pipe fully).

Maintenance Guides / Fitting an adjustable steering column
« on: 15 November 2006, 23:37:41 »


Fairly simple and very worthwhile mod, especially if you are tall.

From the donor car you will need the cowlings and operating lever for the adjuster, also a curved bit of plastic trim that fits between clocks and cowling (1 screw). Try to find a car with correct colour steering wheel and cowlings in good condition and close to same age, there should be less differences in ignition switches then. Try to get the ignition key, you will fit your old lock barrel to keep the same key but if you have the key to the new column it saves drilling out bolts in order to swap over steering lock assemblies.

Disconnect battery.
Remove column cowlings:
Turn steering wheel 90 deg to left of centre, remove plastic cap and screw that becomes visible. Repeat on other side.
Remove 3 screws on bottom, cowling should lift away.
Unlatch and lift out both switch stalks, no need to disconnect.
Disconnect ignition switch wiring (turn to posn. 1 and depress latch in side of connector)

Loosen steering wheel: If lucky you will have a wheel of the correct colour and good condition on your new column so wont have to do this step otherwise....
Remove airbag, two torx screws through rear of wheel...you did disconnect the battery didnt you??
Carefully unplug airbag and put safely to one side.
Disconnect plugs to remote stereo buttons if fitted.
Loosen centre nut 2 turns but do not remove completely. (to preserve your teeth during next step)
Apply load to underside of wheel with your knees whilst striking end of shaft with hammer and alloy or copper drift. The wheel should come free with a sharp knock but keep load applied until it does, if you hit shaft without supporting wheel you will likely collapse the crash structure in the column. Note there is a special puller for this job but it is usually possible without. Do not release the wheel from its splines yet, we need to maintain alignment for a bit longer.
Remove cardboard cover above pedals. Look for pinch bolt where column joins steering gear, start to remove bolt then make sure wheel is set straight ahead and remove bolt completely and open up the split slightly by tapping in a thin cold chisel or screwdriver. Do not turn wheel or column again.
Remove steering wheel nut and wheel.

Disconnect wiring from steering column 'squib', there is a yellow latch to slide out of connector end before the connector comes free.
Open fuse box cover, the column is held by a nut on the RH and a sheer bolt on the LH. Centre punch the sheer bolt then drill off the head, it is a 8mm bolt so pilot 3mm then follow up with 10mm to remove head or drill 6mm then chisel off. Keep the washer, drill or file out hole to fit a replacement 8mm bolt.

Use a torch to peer down length of column, at about mid point there is a bracket facing upwards, fastened with a single bolt, use several long extensions and 13mm socket to remove. Access is improved if you unlatch and unscrew the relay panel. Dont drop the bolt, it seems to hide if you do.
Remove the nut at upper bracket and column should now pull free and wriggle out past wiring looms etc. A bit of levering may be needed to get upper bracket free of dash moulding.

Compare old and new ignition switches, will the plug fit? if not you have to drill out the sheer bolts and swap over the lock assy, You might have to file a notch in lock body or column housing to get lock to fit properly (the auto and manual locks wont interchange without this) use new sheer bolts or socket cap head screws with a bit of locktite.
Swap over the lock barrels, key in, turn to posn 1 then insert rod or allen key etc into small hole in side of lock, barrel will pull out.

Ease new column into place, either align bottom clamp with position of old one or set wheel straight if still fitted.
Fit all bolts loosely then tighten mid clamp first, then upper then pinchbolt with fresh locktite.
Reconnect squib, refit stalks etc.
Refit wheel, nip up but do not fully tighten nut yet until alignment is checked.
Reconnect and refit airbag, reconnect battery and go round block to check steering wheel alignment.
Disconnect battery again, remove air bag again and adjust wheel position or fully tighten wheel.
Fit the half moon plastic filler that goes below speedo on adjustable column cars.
Fit cowlings.
Fit airbag again, and reconnect battery.

If you turn on ignition when air bag is disconnected then warning light will come on and only a trip to the dealer or The Boy will get it activated again.

I suspect you need a Tech 2 session.
Your CD changer wont be compatible either, needs to be a different version of firmware.

Omega General Help / Re: Slight Popping !!
« on: 19 September 2011, 12:56:33 »
Could be the beginnings of a mainifold gasket blowing or a cracked manifold, these seem to be temperature dependant at first.

Could also be the secondary air injection system doing its job, any unburnt fuel re-ignites in the downpipe, noise will stop when the air pump switches off.

Omega General Help / Re: Lower arms and tyres
« on: 07 September 2011, 12:53:08 »
excessive wear on the inner edges is a sign that your camber is set too high (wheels lean in too far at the top). Once you have the new wishbones fitted then get the camber checked and adjusted ASAP.

105
I cant imagine which bit they are referring to unless it means the camcover (with ecotec on it), might be if breathers are blocked :o

If I were buying a 2.0 I would want to hear it running and ideally under load; too many of them have high bore wear and knock under load (piston slap) you can ignore this up to a point and then a ring breaks.
