D-Day

I can not remember the exact location of the brake light switch for a DM of that year but its common for the spring to break inside of these little switches allowing the contact points to stick together same thing with the low air pressure switch

The 750 on the right probably had the bevel square seal because it has the flat top lid that seal is obsolete but a little silicone is fine to reseal and the later square seal works as well

The gasket seal for the luberfiner 750 should be square not round like an o ring fleetguard number is 0101853s

Saw this earlier this week not sure if it’s from coal country but I like the tri drive setup Hendrickson walking beams with the third drive axle cantilevered off of the second drive axle

There was a thread on here from a couple of years ago titled engine size in 65 Mack B53 and he posted some nice pictures proof that the tip turbine will fit under the hood, I do know the front crossmember/engine mount is different also another issue is if you have a single plate clutch with the short bell housing you would want to change to a two plate clutch with a little stronger transmission to handle the higher torque rating and you would have to redrill the rear mounts through the frame relocating them farther to the rear

I have repaired and replaced numerous aluminum frames most were KW and Peterbilt used as log trucks the extreme rough roads would brake the rails vertically near the cab the Mack rails I have only seen small horizontal cracks around the rear suspension other than scale or delaminating as some call the rot where it contacts the steel if its always been on the pavement its probably not a concern easy to check with a good light

Also it would be a good idea to pull the wheel off and measure the splined shaft older columns were 1 1/8” splines newer shaft splines dropped to 1” not sure about 2016

I am lucky to have found part of this B 755 that ran the Al-Can back in the day just parts now but it must’ve been a rough trip running that route

This was built at a local shop and we are grateful for it they built an improved version and that’s how we got this rear steer lowboy sure makes it easier to get around when you have miles of tight turns and alot of switchbacks the driver at the back will suffer dusty conditions but

I have not seen 44 rears set up with soft bushings before but I can see it would not be to bad with a good set of polyurethane bushings if your not loading heavy regularly and maxing out the trunion shaft is the same diameter for the 38 and 44 but the axle housings can be heavier for the 44,000 check the rear right side of the housing for number code stamp for the axle housing rating

He drives this model T and the model A around town daily they get used a lot always good to see him coming down the road

Try John Chalmers 717-334-8709 Cashtown PA. he is in your area is super knowledgeable and has a lot of hard to find parts he should know of anything in existence and if you need anything else from a 711 I have a parts engine for spares

The 864 was finished in 1972 and the ET 1000 did not come out until 1978 so a look at the numbers is important but it all looks good

Helping a friend this weekend put the rear end back in a good ford A model sure is nice to see how all of this is engineered it’s amazing what worked a hundred years ago and it still works great

Just forward of the starter on the edge of the block above the oil pan is where the identification numbers are stamped I think cab over engines were stamped at the right rear
