Stiff gear change
« on: 10 April 2016, 14:09:58 »
2000 2,5 petrol manual estate
Since changing the clutch the gear change on this car has been a bit stiff. After the clutch change I carelessy lifted up the gear lever and dislodged one of the half moon plates into which the screws holding the gear linkage to lever engage. I put it all back eventually and all has worked for six months. May I have overtightened those screws, or is there any need for lubrication of the ball at the base of the gear lever? I don't think it's clutch drag I bled the slave thoroughly.

Ball should be well greased, torque for bolts is in Haynes iirc.

Also check gear lever mounting plate for security and rear mounting for excessive movement  :y

Thanks or advice, have now greased ball and torqued screws to 10Nm. Feels better, give it a full test tomorrow. I imagined those white bits in pic were PTFE so it did not need lubication.

The smear of vaseline like grease all over it on removal might have been a clue ::)

Sorry to report that the change is not much better. It tends to baulk engaging 1st, reverse, and 4th; not unmanageably, but the change is not as sweet as my other Omegas. Haynes describes an adjustment procedure, but it involves service tool KM-631. Can anything useful be done without this tool?

What sort of condition are the bushes on the linkage onto the gearbox?

For the Omega B gearbox you need service tool KM-631A, which is a modd'd version of 631.  Without this adjustment of the  selector lever on 5-speed manual transmission (R 25 and R 28) will be very much hit and miss.
Note this is not a normal/routine service adjustment!

HTH :y

Hard to say with the prop shaft on, but it feels OK. In this shot taken during clutch change it looks OK. Change was normal before clutch change.

Thanks to all for advice. I did have trouble reattatching the gear lever base, but broke nothing as far as I know. Has anyone seen the service tool in use? I appreciate that without it it would be trial and error. Is this worth pursuing?
I am embarrassed to admit that I have lost a gear lever. The rubber lever collar on this car is breaking up, so when I scrapped the 2.0 blue estate (HG gone) I kept many spares - doors, tailgate, battery, radiator, trim bits, even the drop link - and made a point of keeping the gear lever and bits. I can lay hand on all the other bits, but not the gear lever, which I  put somewhere special.

I have found the spare gear lever. I have not yet touched the adjustment, so I shall change the lever first. The orange washer was hanging on the old lever, and I left it hanging there. I see from the spare lever that it should sit in a groove in the lever base;that might help. Pics follow.

I greased he ball with high melting grease and stuck the orange washer to the base of the gear lever with table tennis bat rubber adhesive. Then installed the spare lever, torqued up, tested, now all is well. Change is not quite so easy as my best car, but better than most. Pic follows.
Thanks to all for advice. I'm glad I did not attempt to adjust.
