Hustler 980 tall tub build

If the outboard driven clutch sheave is not wobbling but the inboard side looks like it wobbles your clutch moveable sheave bushing is worn along with the ramp sliders. it takes allot to bend the trans input shaft. Noise is typical when the bushing is worn

Thanks Jersey. The outboard sheaves is wobbling and the mounting bolt is not running on center.

Try changing clutches from machine to machine.

AJ I think I'm just going to swap transmissions. The 980 trans has one other thing I'm not satisfied with, and that is the diamond shifter fitment. Although they fit in the case tight enough for the oring to seal they are sloppy. This is causing some binding when shifting as the diamond wants to rock to the side rather than rotate. The other thing I don't like is the plungers are probably half inch outside the case, even with relined bands. They work fine, but I'm afraid someday it will pull out to the oring before the bands are worn out. I guess that's better than grinding a drum with worn out bands, though.

When I make the swap, I'm removing the red spring from the driven on the 950. The 980 needs absolutely no help with low end torque.

I too was never happy with the way the diamond shifter was designed to shift. I always wanted to make a new pivot pin that would extend up higher than the current one and fit it in a hole above in piece of metal welded to the existing horizontal bracket. That way it would be supported top and bottom and provide for a smooth shift.

[dirtdobber]

Only once I have thought about doing that. I would probably weld a short piece of oversized rod to the diamond pivot and then take it to a machine shop and have it turned down to be true.

Update, and transmission question.

I pulled the trans and tore it down to investigate some things. I have a curious situation with my bands. My bands are newly relined with .040" of liner material, but the plungers run too far out of the case. My drum diameters are fine, at least according to an old post I found indicating the drum diameter should be 6.210. Mine are all within ten thousandths. What I have discovered is that my bands are one inch longer compared to another (worn out and rusty) set of bands. To take up that extra inch of band length, my lining would have to be about 0.110 instead of .040. Anybody ever run into something like this? Are there such things as extra thick lined bands?

I bought the Richards "stronger thicker" bands for my max and ended up having to buy longer bolts because the plungers were so far in the case. Sounds like they might be what you need.

[dirtdobber]

I may wind up having to buy a set of bands. But, I really want to know why my bands are 1 inch longer than a different band I'm comparing it to. Bands stretch, but all of mine are exactly 1 inch longer.

I hope I find out that once upon a time bands were made with much thicker lining. I may have mine relined, again, but thicker this time (if possible)

[Dw89xj]

I wasn't even smart enough to compare mine but I still have my old bands I will compare to the relined bands Martin sent me. You may be into something maybe the relined just aren't as thick. I suppose maybe 1/16 or 1/32" could make an inch over the length a band

I wonder if there was not a plunger length difference over the years with all the out sourcing.

[countrybumpkin]

There are some transmissions out there that were prone to band stretching. Not sure if it was an alloy or tempering problem. I had a bunch relined and some where still too long because they were stretched. Kind of hard to measure the curly things!

[dirtdobber]

AJ, the plungers are the same in the two transmissions.

Country, I don't believe it is possible that all bands would stretch exactly the same. I'm measuring with a piece of fishing line. I clamp one end at the band eye center and then wrap it around the band. I cut it to length at the eye center on the other end of the band. Then, wrapping the line around another band I can see, and measure the difference.

Again with the out sourcing the previous owner may have somehow unknowingly ended up with bands that were made incorrectly by the supplier. They may not have supposed to have been released or went unchecked, had I bought them I would have never measured them.
Perhaps a quick measurement of how far they stick out of the case and how far into the plunger the o ring sits will tell you if you could still use them.

As far as the other post about the shifter wobble, if you have a snap ring trans, you may need the later plate style shifter retainers.

Just a quick question for those followings info, are both transmissions skid steer or borg warner or one of each?

You know what? I don't know. I didn't know there were two manufacturers and visually they look the same. One data plate is completely faded so I'll have to check the castings for info. But, here's what I do know. I'll call the parts t20 the "old" one and the 980 t20 the "new one":

Old one has 9 tooth drums, new one has 18 tooth drums
Both had diamond shifters held in place with the metal straps, not snap rings.
Both have thrust washers.
Old on has a big brake disk mounted with the sprocket on the input side. New one has no brake disk.
Both have U channel plunger controls.
New has bands that are 1 inch longer than old

These long bands will run but I'm so anal I just don't like it. I have pinned the uchannels and when adjusted the plungers are pretty close to the back of channel. If they weren't made of spring steel I could solve this problem pretty quickly!

They are both skid steer.
