super c governor timing marks

Chris from Wa · Oct 24, 2008

Years ago on my Super C, the teeth on the hydraulic pump drive gear broke off and went through the cam and crank gears. The guy that owned it back then just swapped in a C-123 engine from a combine. I am putting the original engine back together and am missing the two timing marks on the gear of the new governor. Has anybody run into this? I didn't see this addressed in the archives.

Your governor gear should have one punch mark and be meshed with the double punch marks on the cam gear as shown in this pic. Hal
PS: The single punch marks on the cam gear should mesh with the single punch marks on the crankshaft gear.

You don't say if you're going to put a magneto or a battery distributor back on, but in either case, you can do some fiddlin' and set the governor/igntion drive gear up.

Assuming you've got the cam gear timed up to the crank, with the motor at TDC on compression on #1 (use the mark on the flywheel, especially with a mag, which doesn't give you as much back and forth adjustment play that a battery distributor does), set the governor gear so that the slot and lug line up between the gear and the back of the mag/distributor when the rotor button under the distributor cap is set (or cocked for a mag) on #1. It will usually be close to 10 o'clock and 4, though I can never (dammit!) remember on which end, so it may look like 2 and 8. To get around my own embarrassing confusion, set your mag or distributor first to get the general orientation, then adjust the gear to match it. You'll need to be close with a mag, but this will certainly get you within range for a battery distributor.

Chris: As Scotty put it, this is not crucial for a distributor ign. I'm confident you know how to do this starting at the distributor and working back to the governor drive gear. If you don't get it right on at governor drive gear, you can make correction at the distributor drive gears.

The main item here is have number 1 terminal of the distributor cap in 2 o'clock position, when number 1 piston is at TDC on compression. From there distributor adjustment will correct timing advance.

There, I'm confident that anyone who can come up with as many jokes about EAST COAST CANADIANS, as you can, will also be able to figure this out, or as they say in Newfoundland, "Let your big jib draw".

Looking from the back towards the drive in the governor, it should be in the 2-8 o'clock position (specifically 35 degrees above horizontal).

"Let your big jib draw", that's a hoot. Is that anything like "Bob's your uncle"? Thanks everyone for the input.
