Title: Another Gearbox Question
Post by: Lightningpower on 22.07. 2010 04:38
On another semi-unit gearbox, I have a B 20 stamped onto the lug.  What could this mean?  Thanks again!

Very interesting, just a guess, one could be off a longstroke rigid the other off a plunger. The sprockets are different, it looks like a 530 on the left and 520 on the right.
