I have started to reassemble after painting though have a small query regarding the rear main roller..

With regards to the rear main bearing housings (2 off) one has three holes (no adjustment) and the other has one hole and two slotted holes (adjustable). Manuals I have downloaded do not indicate which side of the frame the adjustable housing must fit to.

Q1) What is the purpose of rear main roller adjustment? It adjusts the height of the frame on one side only and effectively tilts the frame but why?

Q2) I have already assembled the rear main roller and fitted the adjustable housing to the drive chain side. Is it critical for the adjustable housing to be on any particular side?

Q3) If so what side should it be fitted to?

Hope somone can help,
Cheers, Craig.
