Rear diff housing round tube, not square
terry replied to SpreadingLime's topic in Driveline and Suspension
Round ones were early housings, don't know the exact year they went with the square housings. terry -
I’m thinking no the bronze bushing spindle I believe is threaded on the end and I don’t know if the 44K rubber bushing has any threads. Terry
-
Is it a camel back suspension? Terry
-
Can you post some pics. Of the 44 cutoff? Terry

air shift pto
terry replied to pmolitor's topic in Antique and Classic Mack Trucks General Discussion
Any six speed I have driven always had the main box in 3rd, 4th, or 5th gear, depends on your needed PTO speed. Terry -
Don't know about thread locker on the rod bolts, but on head bolts be sure to run a bottom tap in head bolt holes, and blow out with air, and a die on headbolt threads and , oil threads and washers as you said. terry

It's terrible how all this newer stuff is a POS!
-
Might need a little heat or as I call the blue wrench! Terry

I think a G733 was originaly a cummins engine with a turbo. terry

Learn something new every day! Guess i just never heard it called that. terry

What are you referring to when you say pinion gear in a transmission? Maybe I’m missing something? Terry
-
I know it’s your transmission but with .002 endplay I would call it good, the only place I have set gear backlash is on PTO’s, different gasket thickness’s, there is no way to set backlash between main and countershaft gears. Terry
-
It is definitly set on the rear of back countershaft. terry
-
237 hp engine. Terry
-
Also run a die on both ends of studs, and a bottom tap down block stud holes. Terry
-
But when you preload does that take all your end play away? Yeah them figures for new and used bearings are right on, I never used the string and scale, I used the dial indicator, don’t remember how many thousands though. Terry
-
Joey I looked in one of my old Mack manuals it says on reassembly leave top main shaft out of back box bolt cases together and wrap string around counter shaft and set at so many pounds pull, I never done that to much crap! I used the dial indicator after assembled and set at so many thousands but I don’t remember the exact number. Terry
-
Yeah rear box will work to, some don’t have PTO openings, the rear bearing on rear countershaft is held in by a tapered bearing towards the front, the rear cover and shims press on the bearing outer race to set endplay. Hope I’m explaining this so you understand? Terry no snap rings
-
For some reason I thought the PTO gear was fixed, if nothing else it can be done on the tail end of countershaft with the rear cover off. But I think the PTO gear is pressed on so tight you don’t have to worry about it moving to check this. Terry
-
Been along time since i have done this, but take a dial indicator with a magnetic base and mount it somewhere around PTO , find a fixed gear on countershaft , configure indicator to touch it, take a small pry bar to slide fixed gear forward and back to check end play, then there are shims under countershaft rear cover piece to add or take out shims for desired endplay. Joey might have a different way to measure this. Hope this helps terry Think i used the PTO gear to do this
-
As far as telling a duplex, triplex or quad. Back box length will tell you. Terry
-
When you set the endplay on the countershaft both boxes need to be bolted together, there is a tapered bearing between them, so when you check end play it is for both countershafts, it would be the last thing to do on reassembly. Terry
