The model number is stamped into the case near the big fill plug. It will start with a 'T'.
-
My guess is he can rotate the engine til the clutch number is visible.
-
Trucksplanet.com has some info. It is saying your clutch is a self adjusting type.. hopefully when you look at clutches you can get an adjustable one..
-
It's blurry. I cant expand it correctly. That sucks.
-
Dog dish flywheel is a 14" the one im suggesting would be 15 1/2".. but you would replace the flywheel with an E-7 flywheel.
-
Its a spicer. https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.trucksplanet.com/photo/mack/fm/fm_k501.pdf&ved=2ahUKEwjt_azT0rKMAxVuRDABHep7N4gQ6sMDegQIGhAB&usg=AOvVaw3Cqf3qUjvUV10vpnqnfhr8

Are they Jacobs 690 series? -
Im sure it has you frustrated... 🍻

It may be a Spicer. However, you can put an E-7 flywheel on it and get a Spicer Easy Pedal clutch.. if you have the dog dish flywheel, and are getting it machined, make sure the machine shop knows how to machine it. It needs to be cut in 2 places.. I would compare the costs, and look into a flywheel swap.. lets see what GW and JC say.. they are much smarter than me.

Firing order is: Too Young,,, Too Old,,, Just Right,,, 1-5 3-6 2-4... If you adjusted 6,5,4. Its still wrong. But i respect all the effort you are applying to this. I bet the numbers on the flywheel were hard to find.. Jojo -
Its hard to diagnose electrical issues after the common issues are ruled out.
-
Ok. Im not sure at this point, assuming the headlight switch and turn signal switch is ok. Van you unplug the turn signal switch and try again
-
Ok. That switch can cause issues. Leave it unplugged for now. Do your head light wires still run behind the oil filters? If so, look at 'P' clamps to see if thy are cutting into the wires, as well as rubbing the block, also, check where the go around the steering box for wear.
-
Did you unplug the dash dimmer switch?

He posted a new re-built engine that runs... If so... 5K isnt bad... IMO.. i bet 4K buys it...

All good. But now i have to ask..... Im guessing you either ran the valves using an overlap method, or you were up on #6, but started adjusting on #1?? Or mabey you rotated the engine the wrong way.... Or.. you didnt adjusted the front valves to .024" and the rear valves to .016" ok Your turn... 🤔🍻 -
Well thanks to Hippy, I was able to buy a set of Mack shop manuals. I got them today. 👍
-
Ok. So it has the 9/16" or 14 mm bolt for an adjuster? The one you have to push in and turn with the clutch held down..
-
All that paint is a issue.. is the clutch a rockwell diaphragm clutch?
-
New Granite yes or No
