Definitive answer on layshaft end float
« on: 26.02. 2015 23:52 »
I have searched what feels like 1000 threads and still have no awnser. I've heard " no tighter than .030"  .007, and any number of other. Got the box apart and have .018 now and am deciding if I need to make new thrust washers or not

G'day Dan.
I don't have the "correct" answer but I'd fly with 0.005".
Cheers.

  0.005 is what I aimed for too, and think I settled on about 0.004".
 And at risk of stating the obvious, don't forget the shim inboard of first against third Sliding gear needs the chamfer against the spline. ..
