My new project Sierra T-Boss

[Big Sal]

Just picked it up for $300....need love...but it's what we do....lol

I got some pics of the running gear....I've researched the unit and it's supposed to have 2 trannys right? Mine has one...everything looks like it works as it should....I read that these go forward and reverse when you move the sticks....mine has a shifter to do forward and reverse..and the sticks are on the right instead of left....anybody have any expert opinions on what I got? I hope it's not "frakenstiened" together....lol

looks like a nice machine

Yup, Thats a T-20 shoved in there not the original tranny. If it works, you are probably better off, but it looks kind of cobbed together. I don't like the extension on the input shaft, but at least it is braced. I would redo everything and center the t-20 so the machine is better balanced as well as getting rid of that crazy extension. The good news is you got everything there to work with and the parts for the t-20 are available and still produced.

Thanks Drew...that makes me feel a lot better...lol...I should of done more research on it....but then I probably wouldn't of gotten it. After reading your post I looked at it again and it looks well engineered..the shaft is supported on both sides and they are greasable, there are adjustment assemblies for the chains, again well engineered....when it's running, it goes forward without touching the sticks, just give it throttle you pull them back to turn or stop, when you go in reverse you pull the sticks back to make it move...I guess it's working right. It's got a 10 horse single Briggs in it that moves it, but I have a 440cc twin cylinder 2 stroke Kawasaki out of an Arctic Cat snowmobile that I think will move it better...lol...you guys think it's worth the time/money to put it all together?

Well I decided to tear it down and start the whole process...the more I look over the re-engineering that was done the more I'm thinking "leave well enough alone"....it all works, it's tight, and has slack adjusters and everything....it was definitly well thought out....so I think a clean up of the chassis and check everything, the T-20 probably needs to be gone thru I'm sure...and once the chassis is out I can mount the 440 Kawasaki engine and make an "engine tray" with rubber isolators and adjustment slots for the belt....fix all the small defects in the tub, rewire it and last but not least the tires...lol...should be a wicked ride with a 38hp 2 stroker powering it...

I think you need to replace the exhaust system.

Here is a link to a vid of the way the T-20 is set up in my Trail Boss (the vid is kinda choppy, I don't know why)...both fixed sides of the clutches are on the same side and I'm just wondering if anybody has seen anything set up to run this way...

I dont like the slop and I am confused about the double 40 chain. The t 20 has 50 chain from both sides so whats the extra stuff on the crazy long input shaft. Btw, I believe the po put the extension on so he could sit to the side and still have the engine offset the weight, but if you would center both and align them correctly you could bend your sticks off to the side and be better built and more stable.

Like buggyman said, I think the PO had the side to side play figured in to center the belt...I could take it off and reverse it to put the fixed side of the clutch on the proper side and "fix" it to the shaft (ie weld....lol) so it doesn't move, only the spring side would move at that point....as far as the double 40 chain, it was used as a coupler for the input shaft extention to the trans...everything was designed to be able to be serviced or replaced...I'm curious to see if it actually works the way it sits..it looks funky...but if it works why not!!
