Where do you get the original copper thrust washer BTA101?

don't know that you can get them in copper - but then all of the old diffs I've pulled apart have had fibre washers in them anyway

There were copper ones early on. They were in the diff of my 1966 S, but mostly they are fibre now. Look at:

and any local parts supplier, too.

I have always scrounged them out of old diffs. They will dry up one day though

When you say dry up, you mean they will no longer be obtainable --- don't you. As they are already not available new.

Were only in 3 synchro boxes. I have put them in my MK 2 S box.
They are bronze not copper.

Are you sure they're bronze and not copper?

Colour is too light for copper and they are hard.
I'm a machinist, I know the difference.

Note I am talking about the flat washers behind the side gears which are fibre on 4 synchro boxes.

Just wondering could these washers be sintered bronze?

Sintered bronze is brittle and porous. Mine are not. Look like sheet bronze.
Maybe are brass, but bronze is a better bearing surface.
Even brass would be better than fibre.

I don't like the currently sold fibre ones, they are too thick. Like the damned side cover gaskets are... grrr.
Why can't people make parts correctly. :x

Now I am confused "Brass" "Bronze" Sintered Bronze". Surely some here knows what material these are made of?

I believe the fibre washers are part number BTA101 and the copper the same but with a C suffix, as per the MKO link.

winabbey-Do you have the dimensions for the copper thrust washers.
