HiCustomer Welcome to JA. I am Buddy, and i will try and help you out. Lubricate rocker arm head bolts with clean engine oil.

1-Torque bolts to 100 ft-lbs

2-Torque bolts to 130 ft-lbs

3-Retorque bolts to 130 ft-lbs

4-Now turn bolts additional 90 degrees.

 

Valve specs are exhaust and intake valves set to .025 in.

 

All valves are adjusted by rotating the engine only twice. Roate the crankshaft until the #1 piston is on the compression stroke and timing arrow on the front cover is in line with the TDC mark on the vibration damper.

Note=Confirm that the #1 piston is on the compressoin stroke by turning both push rods by hand to verify that both valves are closed. The valves are closed when the push rods are loose and can be turned.

 

No 1 piston at TDC ( compression ) Set #1 intake, #1 exhaust, #2 intake, #3 exhaust, #4 intake, and #5 exhaust.

 

Roll engine one revolution

No 6 piston at TDC (compression) Set #6 intake, #6 exhaust, #5 intake, #4 exhaust, #3 intake, and #2 exhaust.

 

I hope this helps you out. If you have anymore questions, just ask.

 

THanks

Buddy
