61sleepercab Posted September 6, 2007 Share Posted September 6, 2007 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 Quote Link to comment https://www.bigmacktrucks.com/topic/2830-valve-adjustment-on-673/ Share on other sites More sharing options...
ThaddeusW Posted September 6, 2007 Share Posted September 6, 2007 How about putting it in gear and have someone push or pull while you observe the engine for TDC.

Packer Posted September 6, 2007 Share Posted September 6, 2007 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.Packer Quote Keep a clutchin' Link to comment https://www.bigmacktrucks.com/topic/2830-valve-adjustment-on-673/#findComment-13803 Share on other sites More sharing options...

Maxville Truck Posted September 7, 2007 Share Posted September 7, 2007 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 Quote Link to comment https://www.bigmacktrucks.com/topic/2830-valve-adjustment-on-673/#findComment-13808 Share on other sites More sharing options...
