BA Gearbox mainshaft end-float
Posted: Mon Nov 01, 2021 6:57 am
I am investigating an intermittent transmission noise on my Mk1 '52 Sq.
The first port of call was to check if the nut on the end of the main shaft. All looks good but I noted the end float is 20thou. Does this seem reasonable?
It is a long time since I had the BA box apart but IIRC the output gear is held in the roller bearing by a large retaining nut and the mainshaft passes through the sleeve. Not clear what controls the float of the mainshaft in this gear.
