when i first built it up last year i added shims to take away most of the float but in the back if my mind i kept thinking the float my be for a reason. it worked fine and belt looks in good condition still. so i would like to know please is how others build the layshaft assembly?
I try and get almost no floating movement on the layshaft. I opted for using the zx thrust on the layshaft between the pulleys and if you still have some then wafer thin washers the size of the bearings between the housing and bearings. A fractional amount is acceptable. Other way is if you have screwed your back plate section onto your layshaft then you can move it as far back as possible on the slot and that may help.
