Joey Mack

Working in a dealership had stronger requirements. I adhered to the rules. Hard knocks learning was happening anyway, but I took the schools seriously. I was limited to Mack, but did work on other brands. Take it for what it is.

So, why I am posting the way I am is because I was trained by Mack, and have built a few dozen Mack rears. Of course, I have not seen all issues, but fixed many. I am also a good study and own the books that I was schooled with, 3 sets, to be honest. My library is large. With respect, Jojo

You can come off the fuse panel with a 15 amp fuse, attached to a 30 amp relay, and connect to the heads. You can even go fancy with a head light switch so you can select one or both engine brake heads...

you could put a fuse switch on the shifter for easy access. There would be a lot of switching on and off, but it would work.

I wouldnt say 'Bad'..

given the procedures to set tooth pattern and preload, there would not be enough of the housing left because you need to reach in with tools and strike the bull gear with a dead blow hammer to make adjustments. The thin metal wall of the bowl would likely warp during the cutting process and then not be stable enough for the assembly procedure. Its not a bad idea, I just dont see it holding up. and a 200 series carrier has to be taken apart during the preload and tooth pattern procedures between the spur gear and bull gear, and the bevel gear and bevel pinion, because of the spur shaft housing. A 92/93 series can be done as a complete assembly.

The housings are the same

its 2 bearing caps that have 2 ears on each, so 4 points of contact on the bearings.

Keep in mind. The bull gear in a 200 series is wider than the 92/93 series. There is a cutout in the original tool.

Take your measurements on an assembled carrier. I'm telling you... if the bearing cage tool isn't right, you won't get the carrier to fit in the bowl..

The dowels are like table legs. They are essential and must be the same length. Assuming you are having one made. Are you having one made ?

It engages the ears on the bearing caps, isolating it to fit not only the bolt holes but also the flanges inside the bowl of the carrier housing. The bull gear tooth root pattern and bearing pre load is done with the caging tool in place. The suck part about 200 series carriers is that you have to set top reduction first then pull the spur shift to install the 1 piece bearing housing, then set the spur gear to bull gear tooth root and preload. 92/93 series is easier. Have you tried to take the 200 series rear gear apart yet? If not you need to be mindful of the 1 PC. Spur shaft housing. novice,s break them..

Awesome!!!! I wish I one, and the caging ring to set the bull gear. I could make some money rebuilding Mack rears.

When I decide on Whiskey, I like Jim Beam.

Bob. That was one of my points. Designed to work. Not give me a Caddilac ride. Luv u bud..
