Oh no, T-20 Squealing

[cclingma]

Probably less than an hour on my refreshed T-20 and I've picked up a new noise. Regardless of forward or reverse, when you first push/pull on the latterals it squeals a pretty nasty high pitched squeal. If you go ahead and apply enough pressure to move the squealing stops and all seems normal. Fluid level seems good but, it is synthetic. I did the synthetic thing kindda thinking I was doing a good thing but later read mixed opinions on here. So, anyone think the synthetic could be an issue or am I about to have band or other major problems?

Thanks

Any fluid issues are NOT going to create a squeal.......more likely to be jerky or less than smooth operation.
Did you replace the bearings when you rebuilt it? The input shaft bearing is only about $6 from motion industries....but it is a pain to remove.
Did you bench test the trans before installing? Rotate the input shaft by hand and shift fwd/rev while operating the plungers and watching the output sprockets? I'm wondering if it "felt" OK here.

Your sure its not a belt?

I just rebuilt my T-20 and had a squeal.I also had to pull hard on the sticks to turn. It end up being the bands needing to be adjusted. Mike has posted links to the adjustments of the t-20. just search this forum or message Mike ,he was a big help for me.

First off, thanks for ideas.

I didn't replace any bearings. I actually talked to a fella at Recreatives and based on what I told him about my bearings, he said to clean em up and go for it. Of course, that's assuming I described them correctly.

I guess I can't swear that it's not the belt. I'll have to experiment with that one a little more. Kindda has me thinking it's a possiblity as it sounds the same whether I press forward or reverse and on either side.

I'll also try to play with the adjustment a little. I used the adjustment tools to set it up but have heard that sometimes you can get them a little too tight with that method.

Thanks again.

Forgot to mention I did bench test both by hand and by turning with a drill. Trans worked very nice. shifted forward, reverse, neutral and pressure on the laterals/plungers made the output sprockets act accordingly.

Make sure clutches line up too. I also had a belt problem corrected by alignment.

Also make sure it's not the drive clutch needing some graphite. This happened to me after reconditioning my T-20. I thought I was going to pull the trans again. Turns out the drive clutch was making the noise.

Such a simple thing to do...but you'd be suprised how many people would skip this step
Can you get it to squeal when in nuetral by reving it up? That should narrow it down btwn the clutch and belt

Well I'm a bit of a knot head. It's the belt slipping a little certain conditions. I think I was so badly not wanting it to be the trans that I immediately started thinking that way. New driven clutch and belt but my drive clutch is worn some. Alignment and tension are pretty good. A couple squirts of belt dressing and it's quiet, for now.

Cool! Glad it was the easiest problem to fix. If it does it again maybe your drive clutch is glazed up. Try using a wire brush on it lightly. Then clean it up with some brake cleaner on a rag.
