Laygear End Float BN1-BJ8

[AUSMHLY]

Do all the Healey models, BN1-BJ8 specify the laygear end float to be 0.012?
The two manuals I have don't reference which models.

The green Austin Healey 100/6 and 3000 workshop manual, General Data page 15 states:
Layshaft bearing, End float .012 in (.30mm.)

The Haynes Austin Healey 100/6 & 3000 manual, page 102, gearbox and Overdrive states:
Layshaft bearing , Endfloat 0.021 in (0.30 mm). I'm assuming 0.021 is a misprint, should be 0.012

How important is the accuracy of end float?
Is + or - a few thousand of 0.012 ok?
How or what does end float affect in the transmission?

I'm waiting for a rebuilt laygear 22B141 to arrive from Healey Surgeons.
Bruce sets the end float at .005

I did mention to Bruce the workshop manuals state .012.
No comment from him on that.

What's the advantage of .005 vs .012

What's the advantage of .005 vs .012

You can be anywhere between 0.005 and 0.012. Perhaps as the thrust washer wears, it started closer to 0.005, and 0.012 becomes the limit.
