International 300 timing issue

Jerry Bantz · Oct 6, 2011

Installed a rebuilt hydraulic pump on my International 300, I installed the pump at the same angle the old pump was at but I dropped the chuck out of the distributor that fits into the hydraulic pump. Is there any marks on the flywheel? I dont see any timing pointers on the timing cover. Should I time the motor first then the distibutor? That seems like the logical way to do it. Any advise is apprciated.

Jerry -

There should be a pointer on the engine front cover pointing at the rear flange of the crank pulley. TDC is when the LAST notch in the pulley flange aligns with the pointer (crankshaft being turned in the normal direction of rotation).

However if the pointer is missing all is not lost! Do this:

Remove the #1 (front) spark plug. Stick your thumb over the opening then rotate the crank until you feel pressure building - ie. #1 piston coming up on compression. Now poke a pencil or stiff copper wire into the combustion chamber. Continue turning crank slowly and "feel" for the top of the piston coming up. When your feeler stops moving you will be at TDC. (You should also now see the top of the piston thru the plug opening).

Now turn the distributor drive until the rotor is under the #1 plug tower, then mount it to the engine. Your engine should be timed close enough to start and run. It however will probably need a minor timing adjustment to achieve smoothest running.
