D-Day

This flywheel housing measures 5 7/8 for over all depth and the triplex here the bell housing measures about 8 1/4 also the input shaft protrusion is 3 and 1/2 inches beyond the bell housing you can also see how far the flywheel is protruding

I have always thought the flywheel housing depth was the same it was the bell housing and input shaft that changed in dimension for single or double plate clutch but I can measure it there are a couple of old 13 speed road rangers here small size with air actuated clutch brake they had a little push button on the shifter the bell housing and input shaft is where it gets tricky to locate the right input shaft length and bell housing depth with Mack side mounts

I have one I think it's on a 711 not sure it's the same but it did have a twin disc push type clutch and the starter is on the right, I am quite a good distance from NE Ohio in western NC

Not quite 45 years ago but this is from 35years ago my 49 Willy’s pickup is still my favorite repowered with a 327 and 4 speed it was a lot of fun

Buncombe county and Asheville have 14,000 applicants and FEMA has dispersed over 12 million dollars to residents, statewide there has been over 25,000 applications to FEMA and 27 million dollars distributed

I have worked on 3 Kenworths with consecutive serial numbers from 1964 they came out of the factory with fiberglass hoods and I have seen some from 1963 as well pretty sure they were factory fiberglass also, nice work Bob its getting there

It was common in the 70's and 80's in Washinton state Idaho and Canada to find trucks with an extra gearbox generally a 3 or 4 speed auxillary added for working in the mountains usually made by Brownlipe before Spicer took over they were called a Brownie by the truck drivers

My favorite vintage plate could be Italian or maybe Swedish but I think Italian I love it it was everywhere in the late seventies early eighties I have not seen one in a long time found this one at a friend’s shop a couple months ago perfect for an Italian Mack

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The 750 on the right probably had the bevel square seal because it has the flat top lid that seal is obsolete but a little silicone is fine to reseal and the later square seal works as well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