Hi, I was at first stumped . Then I saw R51/3 in the top right hand corner.
I don't have a concrete answer to your question but have a direction to finding out. Barringtons book http://www.barringtonmotorworks.com/gal ... 22&gid=127 Mark

Hi,

With the pinion gear installed in the housing, and the ring gear and it's associated needle bearings and yellow metal shim installed, if you measure the amount of rotational play in the ring gear, at its edge. That is the gear lash number.

That's what I wanted to know , I appreciate it a lot.

What about the 77mm for the "ideal adjustment value in housing" ?
What's that?

i think I figured what's the 77mm for , distance between the inner side of the pinion ball baring to the center of the disc gear . I just inserted the pinion all the way inside and measured it and it's exactly 77mm.
