Hello Im working on a 1976 10hp briggs model 251417 if I remember correctly. Anyway it has two gears mounted on the inside of the sump cover Im guessing for silent or balance shaft function. But Im having a hard time finding the method to time the gears when installing the cover. Does anyone know where to find this info?
Trying To Figure Out How To Install 10Hp Briggs Sump Cover With Balance Gears.

There are 2 plugs on the back cover that you have to remove.You should be able to slide 2 nails or 2 small punches through both holes and into the holes in the balance gears to hold them in place.
I'm not 100% sure on the block timing but I would say it would have to be at TDC (Top Dead Center).I lost my manuals when my PC hard drive died last month.
Here's 2 pics that show the plugs and the gears with the holes. BE CAREFUL when you remove and Reinstall the plugs.They strip out VERY easily.

Man that's awesome. Basically I used a newer I/C block to rebuild this. It had ball bearings on the crank and no counter balance gears so Im installing old engine cover on this newer block. I removed the cover side bearing off the crank. Engine runs very well but my feet and butt don't like the vibrations.

engine runs now. I think I got gears aligned. its definetly smoother than with out those gears. One question I do have is did they make a ball bearing sump cover with counter weight gears?
