Trunnion spring on 125
 

I restored a 125 about a year ago and in the process of researching and rebuilding everything I replaced the trunnion springs.

Well everything was working fine with this particular part of the transmission, no creep or slop. All was well until last weekend when my son and I were doing a little heavy work with it, pulling a ripper that I had built. This was first heavy pulling job that we had done with it. It usually just pulls an aerator.

Anyways, it was then that we noticed some slop developing in the shifter. We finished the job and I didn't think much of it till my daughters were driving it around the neighborhood and they commented that it wouldn't stay in neutral very good.

I had my son take the fenders off to do a little investigating and I found that the large trunnion spring had begun to collapse already. This doesn't seem right. Has anyone else had trouble with this or did I just get a crappy spring. I bought it from one of the aftermarket suppliers, not sure which one.

Any thoughts?

I can't comment on the longevity of an aftermarket spring but for such a small part that plays such a major roll in your machine, I wouldn't bother trying to save a couple $$'s with an aftermarket, I'd just go with a stock replacement from a dealer. Just my :TwoCents: Good luck! :beerchug:

It wasn't really that I was trying to save a buck on the spring, just convenience of ordering a bunch of parts all in the same place. I figured a spring is a spring, so I never gave it much thought.

Will the friction adjustment help any? What "re-build" everything was included with the speed controls? Inquiring minds want to know :biggrin2:

Can't speak directly to your situation, but I can tell you that I have ordered springs from an aftermarket supplier for a different machine and they stretch out in a very short time. I don't buy springs from them anymore.
