Jesse James 0 #1 Posted December 20, 2009 I started to tear down my K321 today to take to the machinist. Took this picture cause I noticed that there was nothing on the pin to the right of the crank. I believe this is for the balance gear. Motor was on a C-121 with a isolation plate, didn't seem to move much! so I guess my question is, does the balance gear go on that pin, and is the balance gear required?

rickv1957 70 #2 Posted December 20, 2009 I and most others throw them balance gears away,they never did seem to make any difference,Rick :notworthy: Share this post Link to post Share on other sites
Curmudgeon 28 #3 Posted December 21, 2009 Don't be surprised when you pull the crank and find another pin with nothing on it..... Balance gears come in pairs, and as Rick said, most of us leave them out. Share this post Link to post Share on other sites
