case 401

Trying to figure out timing on 401 case. Side window on injector pump set to beveled tooth.
where to see 26 degree BTDC? Unable to find any more marks. Manual mentions flywheel marks, but cant see those either. Need to pull injector pump to rebuild. Replaced transfer pump seal already. Didnt stop leaking fuel in crankcase.
Any help would be great.

The crankshaft front belt pulley has notches at TDC and 26BTDC. There should be a pointer that points forward coming out of the timing gear cover, seen from the injection pump side of tractor. Take the throttle lever pivot bolt in front of the injection pump out and the larger hex headed plug it was screwed into out and you will see another pointer. With the crankshaft at the 26 BTDC mark lined up, there will be a mark lined up with the pointer in the throttle plug hole. You may have to use a mirror to see it. Take the 3 flange bolts to the rear of the hole out to remove the injection pump.
