[QUOTE="skidsteer.ca, post: 2836, member: 307"] Bob I just used a light duty set of chains for a pickup, and cut them down to fit. They were the chain type. The oil in your machine goes right to the bottom of the machine, So the plugs in your photo can't be the drain. Perhaps one is the level. Mine had a dipstick on the oil fill cap. Your foam filled tires are a bonus, no flats. And if the casings are still good when when they are wore down, I believe they can be re-capped and used again. My 773 has them but thay are alittle on the firm side. Your pins definitely have too much side play. If you use pipe to shim them up, use something with a thick wall (outside diameter is around 3/4" more then the inside diameter so the sides have a larger area to wear on. Be sure not to shim them too up tight and remove the "end crush" on the bushing. If I had kept mine I was toying with the idea of replacing the hi/ lo pulley arrangement with a CVT transmission from Comet. Then when you need more speed, just set the throttle higher. The "snowmobile transmission" would automatically down shift to a lower gear when the pushing got tough, and when the going was easy you could have more speed then you have in high. The ratio up shifts under light loads and higher rpm, and downshifts with low engine speed and heavy load. That would have made the 371 act alot like a new hydro drive loader. Ken [/QUOTE]
