H engine timing

Report to Moderator

I have been workling awful hard to rebuild this H engine. So far, I am real happy with where I am. It is now on the engine stand with new pistons, sleeves, rings, mains, rod and cam bearings, except for the flywheel, the rear end is built up, Oil Filer canister installed, lifters in, head rebuilt and ready to install and side covers are on and now I am down to the front end.

I want to make absolutely sure as to the timing of the gears there.

There are 5 gears:

1. the Distributor drive gear
2. The cam gear
3. The gear on the crank
4. An idler gear
5. Govenor drive gear.

As I understand it, I need not be worried with timing on 4 and 5 above cause it is not necessary but that I must get 1,2 and 3 done correctly.

Will one of you who is an expert on the timing, walk through this with me one more time?

Tom I will try to explain this even though I am no expert.There is one mark or dot on the crankshaft gear that meshes with the two marked teeth on the cam shaft gear then mesh the single mark on the camshaft gear to the two marked teeth on the distributor drive gear. I hope this helps.

Single dot to 2 dots apparently does not work.

My crank gear has a single dot "on" a tooth.

The cam gear has a single dot "between" a tooth and a doble dot "on a tooth".

The distributor gear has a double dot "between" the teeth.

APPARENTLY, TO ME, it seems that single to single and double to double is proper???

Tom I do see were the confusion was. I meant the mark between two teeth instead of two marks on one tooth.I don't always get it written down like I mean for it to be. Sorry for the confusion.

Tom, it seems you answered your own question. I suggest you assemble it that way and with the engine at #1 TDC the #1 cam lobes should both be pointed down, (just to cross check yourself), then put rest on and the distributor on and the rotor should point to the #1 position. (per book pix)

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership, ... [Read Article]
