    Thiokol 3700A vs 3700B differences?

    I can't remember for sure, but I think the hydraulic track adjuster is back between the second and third wheel ,fitting facing to the outside you adjust it out then tighten the holding nut back against the frame, this takes the pressure off the hydraulic cylinder. The white grease is lubriplate...

    Thiokol 3700A vs 3700B differences?

    We just used regular chassis lube, not the super sticky extreme pressure grease like you would use on an excavator pins or loader pins.We installed the seals so the new grease would push the old grease out, I know on the lift sheave wheels we used white lubriplate for extreme cold temp, some...

    Thiokol 3700A vs 3700B differences?

    At the ski area where I used to work, we had foam filled front tires and when using the blades and after continued use the foam broke up or we would end up with broken front spindles. These machines were used hard ,2 shifts every night, covering hundreds of acres. We ended up just using the...

    The ones we had at the ski area were red and black mid 70's early 80's machines. we had valley engineering blades made in Maine 6 way and 8 way, never had any with thiokol blades attached. My 2100 has a thiokol 6 way blade on it.Don

    Steering question...Imp

    different brake linings will act different!! the softer one with less metal will steer better, but won't last as long. Basically just run it, use it a while !!if you pull the brake bands later on and there replaced with like material they should both steer the same.

    Tranny woes on 1404 Imp

    Don't adjust the brakes any tighter then you need to steer, if you get them to tight they will be fighting each other putting drag on the differential ,and it also leads to scoring the brake drums. usually if the sticks come back to almost touching the seat when steering ,your good ! Don

    C-4 shift linkage adjustment-help!

    On the sprites with the drop boxes it changes the rotation. On the imp there are no drop boxes, final drive ,the axles go directly into the carrier assembly.Sometimes you can see the wash area on the differential case ,where the ring gear was run properly for years. Who ever put the carrier in...

    C-4 shift linkage adjustment-help!

    The tube and axle should just pull out, at least they did on the imps ive worked on. you may have to break it loose with a joint wedge or thin chisel on the flange. Im assuming the differential is clean and not rusty inside. Don

    C-4 shift linkage adjustment-help!

    Just unbolt the axle tube from the differential housing, it will all come out as a unit, it will be a little heavy. Ir you unbolt the sprocket ,it will make it easier to handle.

    I think I saw Bigfoot!?!

    Mike, They appear to be the 1" size ,same as the ones on my spare tracks.The rollers are pretty good,they are flat for the most part,but some of the flange edges are sharp enough to shave with !! :D I blame that on the long pontoons and a crooked road going up Mt. Washington.Don
