[Fot] Quaife and 4.1 Installation

[Enquiries Road & Track]

if have fitted 3.45 , 3.7, 4.1 & 4.5 ring & pinions to stock hemispheres
over the years and I dont ever recall this problem.

I cant see why the Quaiffe hemisphere would only suit one ratio as the ring
gear thickness changes to compensate for various ratios.

as far as i know,  the factory used the same hemisphere on the various
ratios. the only commonly found problem is the width of the cental pin in
plate type LSD's like Salisbury. These seem to have been made for the live
axle cars, so when fitted to a IRS, the stub axles have to be shortened.

i also suggest you have bought a dud
