HST neutral spring hitting Drive shaft

[Jamesm2888]

Hi 83 B6200, HST 4wd, had to fit a new kubota spec Neutral HST spring, after old one disappeared into ether, its now hitting the driveshaft coupling as it rotates, ive fitted and refitted it, eye of spring in and out, no change, what can I do, space is insanely tight between the coupling and casing of box, one side of coupling hits spring on rotation when moving

Not uncommon. My B1750 had the same problem.

Eventually, I was able to get it to clear but only slightly.

IIRC, the replacement service spring has a small piece of rubber hose inside to damp out vibrations, lessening the problem.

Might want to inspect/change the pedal dampener as well.

If any of these are are worn too much or bent it will do that.

Good point that I forgot to mention.

I replaced bushing 110 as well.

yes thanks for that, ive removed that part today, lots of play, ordered new part 100 110 and.120 today £85 at local kubota, hopefully sort it, ws looking at part 150 to 170 cannot see anywhere in the vicinity that the roller comes into contact with, what does it connct to assume it should be on the casing of chassis, could it have been discarded at some point?
