Expert advice needed - Clutch on an RM250T
« on: September 08, 2013, 07:43:23 pm »
OK Suzuki gurus. Today I replaced the whole clutch on my 1980 RM250T. I replaced everything, even the pushrods. One curious thing is that the new rods, which are correct according to Partzilla, are different to the originals. The originals have one rounded end and a flat end, whereas the new ones are rounded at both ends.

It seems the original part number supersedes to a new number so I assume the design was changed.

Now, my question. Is the ball bearing still required with the new rods? I have used it but the adjuster now stands proud of the locknut by several mm more than it did, and looks like it'll come close to rubbing on the clutch cover. I have a vague recollection that the ball was not required with the new design rods, is that true?

Graeme, I recall the very same change on a Suzuki two stroke agi bike, It did have the ball deleted as per the replacement memorandum  . That dual rounded rod had obvious hardening on the ends. Most likely yours will appear the same or is completely hardened.
I don't pretend to be an expert but offer this from experience. Cheers

I may not agree with what you have to say, but I'll defend to the death your right to say it.

Haven't directly measured them, but my guess is yes. I suppose if they measure out as longer by about half the width of the ball, my question is answered...

yes if they are the same lenth leave the ball in if the new rod is longer it should be the same lenth as the old rod and the ball together

Graeme ....  part # 23111-39101  was only used on Rm 250 N/T  Rm 400 N/T  plus Rm 465 . In Suzuki wisdom they have crossed it over to road bike's and hence the part you have now being  23111-15501 .
For me had the same problem when I rebuilt mine and decided to stay with old rods and ball as the new did not work and had the same clearance problems. 
Part # = 23111-15501
Part Description = ROD,CLUTCH PUSH,LEFT
Model Count = 33

Hmmm... I measured the new and old rods and they seem to be pretty much identical overall length which seems strange. Now I'm not too sure which way to go!!

Also, should the clutch push piece rotate smoothly on the thrust bearing? Once it's got some tension on it it's fairly rough and that seems to be due to the machined surface of the push piece bearing face. I guess it doesn't matter, I've just ordered new parts rather than worry about whether the old ones are any good...
