This is something I'm currently working on as well for my b81 the only problem I found so far is the maxi chamber I have has 2 ports on the service brake side one will be sticking almost straight up but the other port will interfere with the inspection plate for the brakes but only on the driver side. Here are a few pictures from a show I went to.this is a b81 dump

How about the brake pedal mount ? The floor in that truck should be the same as a b81

Found this on Facebook a few months back.

When I converted mine I need the following-water pump, gaskets,oil cooler, oiler cooler tube to spin on housing, and spin on housing. Plus new O-rings. Remember there are two different size o-rings that look similar. As far as the water filter its just the water filter manifold and gaskets.

thanks for the info

doesn't your 237 already have a coolant filter? if not it must be a really early one. I have only saw a few 237's with the 711 style water manifold and the big lubrifiner canister instead of spin ons.

yes Matt it is a early 237 out of a r my friend has a 71 r model with a 237 and the filter housing is mounted on the frame behind the cab, it's pretty much set up the same way my 711 was.

I'll see what I got by next week if your not in a hurry I might have a used one too

from the looks of it the coolent filter piece won't work with what I have. I need to figure out how the oil filter mount bolts on the engine as well , I'm not sure if there is more pieces involved or not.

I'm looking for the parts needed to convert to spin on filters oil,fuel and coolent.

There is no balance problem but make sure the flywheel is in time with the crank.There is timing marks on the flywheel but the 237 may have the timing marker on front balancer

thanks

Hi I'm looking for some advice or tips with putting the fly wheel and clutch that was on my 711 on to a 237. I'm guessing the fly wheel will bolt on but I'm just wondering if there would be any balance issues or any other dumb little things I'm not seeing. The clutch I have is a cl50

Thanks Rudy

I've looked into these but found the studs not long enough to fit through the bracket with 65 rears. I don't think it's safe to take apart the chamber and install longer studs.

A friend of mine bought a b61 dump and it looks to have 44k rears but the brackets look to be the same as mine and I'm pretty sure the truck has there's maxi chambers on them I'll take a few pictures when I get down there

I also own a b81 that I'm trying to install newer brake chambers on. Looking for a better solution to replace the old service cans

here is what I found today. Maxi chambers I have to find out the diameter yet though. I'm guessing these will give enough brake power and then a parking brake as well.

Well I haven't made too much progress on my truck but I'm back on the project. I got the drive shaft out and the trans out last night. I was working on the front axle back in the winter and discovered I need king pins and a deal fell through for a set of 22 in hubs.

I am also trying to figure out what to do with the rear breaks, I would like to put modern cans on the truck and the smallest one's I can find are 24/24 chambers but there a little to big in diameter.

I am in need of a set of 22 inch spokes for a fa600 front axle. I have a set of 24's I'm willing to trade as well.

Did anyone ever try seeing if the b model tops fit the r model bottoms at all ?

The weight of my B87 is around 25,000 lbs.It has a triple frame,1200x24's tires,20,000 lb front axle,65,000 rears.

thanks for the heads up on the weight.

this really sucks to hear i just talked to him in the beginning of January, i was supposed to take a trip to his place in the vary near future.

YouTube rudy?

Was wondering if it was

Same truck .

Oh no you guys figured me out, yes that's my truck and yes that's me dumping cans of ether into the turbo.

Don't forget any "new" part may bring "new" issues.

I know that's the scary part to trust the person saying this engine runs great and I buy then it blows up.

The tranny box brake down seems repairable. Welding, soldering, brass soldering or just epoxy but well pre-cleaned and degreased.

The generator mounting area doesn't look nice. Maybe to drill through and put studs instead of bolts?

that's what a friend of mine suggested about the generator mount holes , try to salvage what I can of the threads and soder studs in. If I come across a better engine for a good price will will get rid of this old 711.

On the center bolt if you don't have the right tools i.e. torque multiplyer. large impact. ect.. wait til you are getting ready for paint and take it to a spring shop have them do both sides and in a few hours and a couple hundred it will be just like new.

I do for the most part have the tools or access to them it's just the condition of the other bolt that scares me.

As long as the rear u bolts are tight, the loose center bolt should not bother a thing, they only hold the pack together till the u bolts are torqued.

I was wondering if it would make a difference or not

So I found proof that some people should not be allowed to work on trucks.this is where the generator bracket should mount.

yup, agree looks like a water push out. good welding shop can weld that right up with cast iron rod. I have seen a few Mack trans broke in this same spot actually. mine has about 15 pounds of brass on it. I ended up changing out the front case with a spare. glad to see you moving along on this gem and decided not to sell it.

a friend of mine is going to pin it

So what do you think

Caused the crack in case?

Water froze and cracked?

Or previous transmission failure?

Looks fixable though .

I'm guessing a failure and maybe they were in a hurry so they just fixed the internal problems.

First let me start by stating I am a rookie driver so I'm brand new to most of this stuff....in the older RD models I noticed two gear sticks....can one of you veterans please explain what the hell this is about....I almost crapped my pants...very intimidating....

Go on YouTube and search Mack b model shifting or shifting a r model there are a few videos
