D-Day

 The 750 on the right probably had the bevel square seal because it has the flat top lid that seal is obsolete but a little silicone is fine to reseal and the later square seal works as well 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

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

It doesn't look bad so I would say they should be able to cut it realign and weld it back up sometimes the housing will get twisted bad enough that it becomes very difficult to get the differential in and out especially back in just another thing to check before repair or replace decision is made.

It looks like the Spindle is bent where it is attached to the axle housing I have seen them bent before the older ductile iron housings had a replaceable spindle press fit with a retaining bolt on the back of the housing but all of the others are welded it can be repaired or replace the housing.

Just got a message from the local ATHS that the truck show in Cherokee tomorrow just got moved to 1501 Acquoni Road Cherokee for what ever reason

I drove a 1997 Mack CH613 Gold bulldog with the Elite interior for the owner operator. I think the Mack Motor had 400hp. Pulled 34,000lbs plus 12,000lbs at 70mph no problem

Wind resistance and wind direction can have more effect than weight. When I pulled 48K+ re-bar loads, my mileage was closed to what I would get with an empty trailer. Sure it pulled the grades slower but it also rolled along on the down hill side much further without needing throttle, was less effected by wind gusts etc.

Because wind resistance goes to the square of speed, a little increase in speed makes a big difference in power required to move at that speed, and of course fuel to to get that power.

Thanks for the truck driver point of view on these things some of us who have never driven do not know these interesting things about trucking if you work on the sidelines its hard to imagine how it all works as a mechanic its not always easy to figure out the drivers point of view

was just checking how did the electric B mod project come out

Hope to see that Brockway looking as good as the H model you do some nice work there

I was lucky enough to see the Mack finished and it is excellent I think I have an Extra turbo for that 335 if you need one, dam things are getting hard to find fast

Also Check the ground connections between the battery and frame also coming off the engine the point where the wire end connector is crimped on to the wire as well a little corrosion between the wire and end connector hard to see but problematic

Just remembered a friend bought this last month B61 with 673 I will try to get some better pictures when he starts working on it 

Glad to see you back on again this is a 65B755 with factory shepherd power steering box you’re steering column looks good for the mod if you need measurements or specs for the sector shaft length I can get that the frame mod is not good but you can fix that I will try to get some more pictures from a B model that was converted to a 711 may help a bit
