Farmall Super M

Valve adjustment process—Farmall 4 cylinder: Firing order 1-3-4-2
1. While slowly turning the engine with the crank, watch when #1 cylinder (front one) exhaust valve closes and #1 intake valve starts to open. That is when the piston is at Top Dead Center (TDC). Note: the timing pointer should be lined up with the I I mark (double line) on the front pulley.
2. Rotate the crankshaft exactly 1 rotation to put the #1 piston at TDC again with both valves closed and ready for adjustment. Adjust the valve to rocker arm clearance so the feeler gauge has a slight drag as you pull it out. (check specifications for correct amount) Be sure to tighten the lock nut!! Note: this is where you can set ignition timing also.
3. With both valves set on #1, rotate the crankshaft ˝ turn and #3 cylinder will be in position to adjust it’s valves. 4. One more ˝ turn of the crank and #4 can be adjusted. Note: the timing pointer will be at the I I mark again.
5. Once more turn the crank ˝ rotation and #2 can be set.
6. Re-check all lock nuts, install a new gasket, and you are done.
