Triumph TR3 - Shims for Rear Hub to Axle Flange

I'm reinstalling my axle/hub assemblies into the differential. Because I've painted both sides of the brake backplate with POR-15, I'm guessing the shim pack between the backplate the axle flange is no longer correct.

What's the procedure to determine the correct shim pack thickness, and what's the right measurement spec? I've not been able to locate this information in either the factory shop manual or my Haynes book.

TIA,

Hi Bill:
If you look at the original workshop manual, Supplement for TR3 "Rear Axel", look at page 4 "to reassemble" para (v)through (vii)you will find all the info you need.
Good luck

I installed the hubs and axles yesterday. The dial indicator showed .010 of float on both sides. The spec calls for between .004 and .006. I picked up a micrometer today so that I can identify the correct shims to withdraw.

Just out of curiosity, how far out of spec am I? Would it be better to err on the low side or the high side of the spec?

Thanks for the help with this!

Bill - Wait and see what you have for thicknesses. It may turn out that you have no choice. Maybe your only choice will turn out to remove a 0.006" and you would be right in the middle. See what I mean ?
