Help identifying Cummins

Correct, there is a rearward pull on the crank when pushing the clutch pedal down, but I’ve never heard of an adjustment itself effecting the bearings….

 

It sure does whether it’s CAT, Cummins or Detroit. You run one out of free travel long enough they will #### the thrust bearings out.

 

True, I was overthinking it I guess, hard for me to visualize anyone running a clutch with no free play. But there’s some boneheads out there too….

 

Also been known to shear off the flywheel bolts too from time to time.

 

I've made more than my share of service calls where adjustment was let go so long the clutch started slipping.

Waaayyy past losing free travel. Imagine what the sliding clutches in the tranny looked like, cause you know they had no clutch brake either

 

#### ! them ######## are chewed up .

 

Myself I'd yank the engine and send the block and crank out to a machine shop. Its really not very expensive. I had a 3406 block get hot tanked, decked, all 6 liner seal bores cut/sleeved, crank and cam polished for about $3500 Canadian.
