    Just wondering if I need to reassemble the drive shaft from my R75/5 in any relative position? See when we had it in the press and were heating it up, it went BOOM! Knocked my buddy on to the floor and then I fell down laughing at him :rofl Problem is, I guess my dumb ass must have baked the markings right off the parts...:cry I see that there is a small hole in the largest part of the OD on the spline connection and since there is just a taper for a press fit it can line up with anything...any thoughts?

    Correct, it can line up anywhere. Make sure you completely clean up the mating surfaces!

    ...and whatever you use to clean make sure it evaporates completely. Assemble it clean and DRY.

    Then wipe it down with a white spirit which evaporates completely.

    White spirit is camp stove fuel (otherwise known as white gas or naptha). It's a good solvent which evaporates cleanly. I first started using in an aircraft component shop that I worked in - it was recommended by manufacturers.

    If you have any of them surface preparation products, to be used "before and after sanding" to remove waxes and sillycones before painting, it is also white spirits/naphta/Coleman fuel.

    Yep bought some specialized Rustoleum product before I figured it out. Well figured out that I could have used my Coleman fuel would have saved me $10.00. Only had to smell the Rusto to find out.Should have done that at the store....:wink:

    Someone gave me a BMW Zippo lighter....guess what's in it? Sure ain't overpriced lighter fluid aka Naphta.

    OK ready to go, clean and assembled. Should l attempt to "hold" the u-joint and torque the nut in place or bolt it to the transmission first? I think bolting it up makes more sense but I don't want to damage the tranny. Of couse I would hold the drive shaft while torquing...

    Hmmm... iirc that nut takes a huge amount of torque, and I am not sure I would want to be torquing the u-joint at the other end... if you bolt up to tranny to stabilize and hold that end of the shaft, I would still immobilize the shaft somehow between the u-joint and the bell end...

    Cycle Works recommends holding the yoke that is part of the driveshaft in a vice "so that the jaws close on the flat area around the holes that the cross is in".
