Yo Earl!
Okay, how does it work. First, did you read my webpage with the instructions???
www.parsko.com/Personal/Husaberg/husaberg.html (I think)
In theory, that tube could be around 3 inches shorter. Okay, you are doing the first side of the crank, into the first half of the case (most likely the flywheel side first.
Bearings all in. Slide crank onto bearing just to the point where it wants to begin its "press fit" into the bearing. So, this means part of it will stick out through the case on the outside. Slide the tube over the crank, so it is sitting against the outside of the case. Slide in the 6" long x 1" dia bolt, with the head of the bolt first (of which you have welded on the appropriate nut to thread onto that side of the case, should be left handed thread for the flywheel side). Thread the nut/bolt assembly onto the threads on the end of the crank. Slide the tapered roller bearing (AND RACE) onto the shaft of the 6"long x 1" dia bolt. It should sit on the end face of the 2" dia tube. I think at this point you ahve the option of using a washer over the bearing. Place the nut of the 1" dia bolt onto the 1" dia bolt and thread it on down to the bearing.
At this point, you should have the crank sitting around 1/2" from being fully installed into the bearing. The tube/1"bolt/tapered bearing assembly should be attached on the outside.
TIGHTEN THE 1" BOLT. This draws the crank into the bearing.
Remove apparatus, and repeat (using the OTHER 6" long by 1" dia bolt with the right hand thread nut welded onto it) on the other side.
Is this still unclear? Let me know, I can try to take a picture of the apparatus in different conditions. Draw it out on a piece of paper, it will become clear to you.
