Valve Adjustment On 673

Recommended Posts

Need some tips on valve adjustment on a non turbo 673. My crank pulley is so close the radiator that I cannot get to the crank nut to index the motor to check valve clearance. What do you do pull fuel knob out and bump the starter to get on TDC? I need some tips. Thanks

How about putting it in gear and have someone push or pull while you observe the engine for TDC.

Or bar the engine over using the flywheel teeth?

Cummins engines were turned that way in the past, and there was a special tool that was bolted to the bellhousing and was a one hand operation.

I like to jack up one rear wheel and put the trans in high gear in both boxs and get some one to bump over the wheel which a little girl can do while you watch the marks and they will be on bottom of fly wheel or on latter engines on damper or if out of a f model they can be on top of flywheel glenn

I would assume you have a fan cutch?.....if so take a piece of flat metal about 2 inches long, 1 inch wide, grind a small groove in the centr of each end... now prop that between a clutch fan mounting bolt and fan mounting bolt, grab the fan blade and push against the fan belts (for tension) and spin your motor to where you need it..... I do it all the time. saves having to turn it by the flywheel teeth.. good luck
