Subject: Re: [Fot] Fwd: Crown and pinion gear break in
=20
Thanks, this write up is interesting. I have read the same notes about =
the reference to the measurement from the carrier/bearing center line to =
the back of the pinion head.
=20
The manual does indicate how to interpret the stamping on the top of the =
head. =E2=80=98N=E2=80=99 means normal, +/- number indicates what to =
adjust the pinion set too.
=20
The factory installed a shim between the pinion and the head bearing to =
adjust the center line to top of pinion measurement based on =
=E2=80=98N=E2=80=99 or the +/- #.
=20
Of the diffs I=E2=80=99ve rebuilt I=E2=80=99ve found the +/- # and one =
with =E2=80=98N=E2=80=99. I=E2=80=99ve also measured the head shim =
thickness and pinion head thickness.
=20
The measurement I make using a pinion setting tool from Jegs is =
critical, so far when I=E2=80=99ve installed new bearings and the =
original head shim, I=E2=80=99ve been able to set the pinion height as I =
found it.
=20
The follow up check is to blue the gear mesh after first making sure the =
back lash is within spec (.004 to .006).
=20
None of the normal parts houses sell this shim, the shim they sell goes =
behind the bearing race. The head shims I=E2=80=99ve measured has varied =
in thickness from .037 to .042.
=20
Head thickness also has varied from 1.286 to 1.311.
=20
The other variable, which I haven=E2=80=99t measured, would be the =
dimension to the race seat from a reference point which also could be a =
variable (cover gasket surfaced at the mounting surface or from the =
front support bar).
=20
When these were built 40 plus years ago the factory had method =
that=E2=80=99s not described in the manuals. Not having bought a ring =
and pinion set yet, I=E2=80=99m wondering what instruction one would =
get. What I=E2=80=99ve read on line about current methods, instructions =
would be provided on how to set the pinion in relation to the carrier =
line as that=E2=80=99s how the gears were ground together to make a =
matching set. This would apply to Ford, GM etc.
=20
Pass this on to those in the email thread if they=E2=80=99d like to pick =
my brain.

I looked at my TR3, TR4/4A, and TR250/6 shop manuals, and all of them =
show the same factory tools to set the pinion depth measuring to the TOP =
of the pinion head. So why do the TR3 and 4 manuals have a rear axle =

The "92" is the "matched set" number and should correspond with the set =
