The pinion has two ground bearing surfaces plus a spline on one end

assume both the gear and spline are metric. I am looking at reparing
the existing pinion shaft, but want to explore finding a replacement
first.


Perhaps a last resort, but I just had a couple gears that need to be
duplicated quoted by these folks.

One part was a non-standard (extended pitch) 8DP pinion on the end of
a shaft, with two bearing seats and a locknut thread, made from 4150
with induction hardened teeth. The price was about $900 for two
pieces, including an engineering charge to measure and document the
original gears.

By no means cheap, but it didn't seem unreasonable to me.
