Hustler 980 tall tub build

So, here's what I know so far. The best explanation anyone has come up with is that I have a set of bands that was simply manufactured wrong. I talked with Transmission Crafters, and they can't put a lining on the band thick enough to take up the difference. They are presently lined with with .040 material, and it would need .100 material, which won't work due to cracking, sheer, etc. Plus they don't have anything that thick.

I haven't talked to Richard Clark, as I see no reason to at this point since I can't reline my long bands. So, I'm going to shorten the bands and run them. If they break I have nothing to lose but a little time, a T20 gasket and fluid, and hurt pride when a quad or side by side has to tow me. Then, I will have to buy a set of bands or scrounge around for a set to reline. I have an old set but they are rust damaged.

hey dobber ...i have a set of bands out of my 2001 max 2 t20 from when don kenyon installed new ones for me maybe 2 years ago . they were in pretty good shape , but i had already bought the new ones from r. relics . your welcome to them if they will work . what info would you need to see if they are a fit for you ? johnboy va.

JB that is great! My long bands are 58 5/8 inches around the outer circumference, center of eye to center of eye. Yours should be 57 5/8 or there abouts. I measure by wrapping a fishing line around the band. I guess a sewing tape would work also.

Thanks.

dob...post your phone # or address and i'll send them tomorrow. j.b.

[dirtdobber]

Thank you JB. I sent you a private message.

[dirtdobber]

JB I received the bands today and they are going to be perfect. Thank you very much!

dob...your very welcome ! you know it's too bad we don't live closer to each other so we could ride and work on machines together . i'm sure many members would like to be closer to a fellow enthusiast . i'm sure the no. carolina '' busco '' gathering is too far for you . it's the only chance i get to ride with others. keep us posted on your project . johnboy va.

I would like to make the busco trip sometime. I have family in sanford and holly springs NC, so it could be a dual purpose trip.

Going to drop the trans back in tomorrow and hopefully go for a test run.

Thanks to john swenson and transmission crafters the plungers now are in the right position

Notice this case has been sleeved at the plungers and also has a bushing the shifter rides in.

My case has sleeves on each shifter hole, now I will have to look closer at the plunger holes.

Hey Dirtdobber I've noticed any T20 that I've came across from Jonesboro Arkansas have always been sleeved in plunger and shifter holes. Just a FYI.

[dirtdobber]

Thanks dave. I was wondering if this case had been worn out and repaired but apparantly not.

No fun for me yesterday. Installed the transmission and new driven clutch only to discover the belt rides higher in the new clutch than it did in the old, about a quarter inch difference. So, this makes my belt too short now. So, I have to either get a slightly longer belt, or shim the new clutch open just a hair.

[dirtdobber]

Got the 980 all back together and went for a spin this afternoon. Still have some tuning to do. Here's where I am:
* The new driven clutch came with a green spring, so gave it a try. I wish I had changed it because it stays in "low gear" waaaay too much.

* I've got a geometry problem with the diamond shifter on the right hand side. I had this problem in the first test run, but I was hoping that changing to a different case would correct it. When in forward or reverse it won't pull itself around to neutral unless I give it a nudge. Nothing wrong inside the T20, it's just a geometry problem.

* I'm more than pleased with the engine compartment air flow system. It was 91 degrees today and the surface of the engine compartment was within 5 degrees of the opposite end of the machine.

* I'm going to make some radiator modifications. The engine temp was climbing more than it should in my opinion. I did not get it hot. First, I need to make a small shroud to take up a little space between the fan and radiator. I'm losing a little air here. Next, I need to fashion some type of louvered cover for the radiator. It is exposed to direct sun, so I suspect that is robbing some of its heat exchange capacity.

* Band chatter. I'm running type F fluid with 4 ounces of friction modifier, but still getting some chatter. Not sure what to do about it.

* I didn't get to float as much as I would have liked. It was windy on the lake and I didn't want to risk the wind taking me "out to sea" or pinning me in some trees. I'm just not comfortable yet with this machine. It is not very stable when floating.

Other than fine tuning those things, I like it! This thing is is a beast compared to the 950.

Awesome to hear! I can't wait til I'm down to the little stuff and fine tuning.

Would redrilling the hole in the diamond change the geometry enough to cure the sticking problem?
