262 judder when moving off.

Post by Seamus » Mon Mar 11, 2019 10:12 pm

Hi all, our 262 has had a judder in the driveline when the clutch is being released. It's been noticeable for a few years but lately it's been getting worse. Recently I removed the back end to clean hydraulic filter and noticed that the central diff pin had badly worn bushes so I replaced the pin and both bushes, thought this had improved things but seemingly not. This judder may have originated from an incorrectly set toggle arms on the pressure plate when it was fitted a long time ago as the judder was severe when a new clutch unit was fitted and when the square inspection plate was removed the cover was running slightly out of true. It was adjusted as much as possible through the inspection hole but I think it was never perfected. I'm guessing there may be wear in the many couplings in the bell housing but is there anywhere else I should look first? This is a loader tractor so all this juddering is not good long term. There is around 23 thousand hours on the tractor and I fitted a synchro box instead of a crash box around 7 thousand hours ago.
Thanks for any replies.
Seamus.

hi . sounds like the thrust ring on the clutch is out and not running true could be adjustment related or worn levers . has your clutch cover got the plate bolted on top of it under the steering orbital unit or is it a solid piece if you can take the plate off it ll let you see inside a bit better .

Hi Diggerdeano, my tractor has the side inspection plate, it's a power assisted model. Is there room to check/ adjust the thrust ring through the plate or maybe I'd be as well to lift the entire cover off to check couplings for wear also. Can I check thrust ring statically or set up a dial indicator and run/rotate engine by hand? Thanks for reply.

hi you can adjust them via the little inspection plate but you cant see the thrust ring to see when its running true . dial gauge is the best way but going by eye is an acceptable method . you need to spin the engine over to see if the ring is true dont start it just crank it . ive not used a dial gauge on any of mine and they are all fine no judder at biting point .

Thanks Diggerdeano, it's cover off time then at the next chance I get, fairly sure there's no top hatch on the cover unless it's under where the steering box bolts on. No harm removing cover anyway to check for other wear.
