Shocking find on Ralf....
« on: 07 May 2012, 19:53:31 »

Very productive day today stripping down ready to practise the cambelt replacement job.

Only a couple of things went wrong...

1.) I dropped a bolt to one of the Aux pullies down the drain in front of the garage  ::) but no big deal I'm sure I'll get a replacement from Vx or somewhere and 2.) I cracked the timing belt cover. Anyway, we'll come to that in a minute.

This pic is awesome...... N.B, the cam pulleys have been marked by someone in tipex as has the casing.
Cams 2, 3 and 4 are roughly in correct position with the crank at TDC (also someone marked with tipex). But check out cam 1.............4 or 5 teeth behind where it should be  :o :o :o :o


Another pic showing the whole timing set up with Cam 1 sticking out like a sore thumb  ;D


This is the tensioner with the crank @ TDC..... again if I'm right in thinking looks wrong too (should be lined up with the marking???)


Removed items....I put all screws with their respective components to aid reassembly. Note the pulley missing a bolt  ::)


The reason I broke the cam casing  ::) I can't seem to remove the assembly holding the aux belt tensioner.


Broken casing.... not too bad. The pics not great but you can just see three specs of light shining through.


Finally, the Aux belt. Looks nackered to me and I assume it should be replaced if I was to do the job on my good car.



SO.

With all the above, how the hell could that cam timing get out by so much  :-\ :-\ :-\ :-\ :-\

Anyway, awesome day. No real dramas. I would say that the crank pulley was a fekking beatch to get off. No movement from rubber hammer. Got evil with a pretty substantial pry bar behind it. Slowly pushed against and it popped off. Was worried for a while though  ;D

Oh and one thing I just remembered..... Water pump has no play in it and no noise when pulley spun. Good!
The Aux belt tensioner does sound gritty when you spin it so I will be following Mark's excellent advice with re-packing it with grease to make it silent  :y

Anyway, hope you enjoy the update as much as I enjoyed doing it :):):)

Cheers.

Aux belt for the bin  ;) Cambelt dont look too bad though , although reading on here its the tensioners that are also very important to replace .
Glad you had fun , cant you fish that bolt out the drain with a magnet or something

Webby... I'm not convinced you've/previous person has that timed right ;) If it was 4 teeth out it would almost certainly have bent valves and not run ;)

Whatever it is... I didn't do it

So what do you reckon Lazy? I have checked this correctly haven't I?  :-\ Crank ''notch'' is at 6pm and that's how the cams look.

Ps, just to let you know these are my findings from simply pulling off the belt cover and turning the crank.... i#ve not got the kit yet so i'm not going to have the belt off, re-time etc until i get that.... this was just how it was when i found it  :y

If that cam is out don't panic to much. My old one I had one cam a tooth out 2 cams 2 teeth out and the last cam was 4 teeth out!!!! All compressions were spot on and it ran spot on once I sorted it out.

Thanks Doz. Certainly explains why it sounds like a tractor.

I'll hopefully be re-timing this weekend. But still very intrigued as to how this would have happened. Is this smething mechanical gone wrong or has someone fiddled with this and messed it up? Not bothered cos it's going to be sorted... just out of interest

Your tensioner looks like it's saying the belts slack (might be saying it's tight but I'd bet slack). Mine was caused by a previous broken tensioner. The car had been repaired after the belt let go but they hadn't bothered to check for all the missing bits. A old ball bearing had managed to stow away and once it found it's way into the belt teeth it caused havoc

Is it not if its advanced it causes problems ?. On my 4 pot, the valves got lunched because the belt advanced the timing by a few teeth. If the exhaust valves open a bit late, it shouldn't matter too much, power will be down but....
