Well, installed the second replacement unit from vendor "B" and brakes worked great but...

Airpack 1: This is the original airpack when the previous owner bought the truck probably 15 years ago. It is likely just an age/ lack of maintenance related failure. Airpack 2: This was a new airpack. When received, this airpack was soaked in brake fluid and there was thread damage to...

For the second airpack, leaving the shuttle valve on the back open or plugged made no difference. No air comes out if it. The port on the front valve, I believe service out, only runs with a short line to the brake light switch. I did all of this to eliminate potential issues with the two...

Sent the first replacement airpack back to "vendor A." Realizing that there will probably be a two week turnaround and really wanting to get this truck ready for a July 4th parade, I ordered a rebuilt airpack from "vendor B" and installed it today. Good news is that it now has great brakes...

I reconnected the airpack: hydraulic in from master cylinder, hydraulic out to wheel cylinders, air in from the tank, service air out to the brake light switch, kept the air vent in the same spot, and left the shuttle valve at the rear of the airpack open (didn't work plugged). Brakes worked...

I am having trouble with the brakes on my M818. A little history. The truck has been modified to one rear axle and the glad hands removed/ capped off. I was having trouble with the brakes wherein I had good power brakes but as I sat with my foot on the brake pedal, the pedal would rise and...

Another auction purchase. Really good value IMHO.

I still have the regular heater under the dash that can be used for defrost.

The proper tach drive was not available. I cut and slit a thin wall brass tube from a hobby shop and inserted this into the original tach drive. Works perfectly.

The success with the Benmar cabin heater led to the installation of a coolant heater.... Benmar also made a 15k btu coolant heater; it didn't put out as much heat as my Stewart Warner 939J24 but the small size and built in pump made it very appealing. I first planned on installing it in the...

A better pic showing the general location. Yes, the outlet will be very hot. I plan on rolling a shroud to prevent inadvertent contact. The fuel filter is the one used on the multifuel flame heater. I tested this heater quite a few times before committing to the install. Once the air is out...

I installed a pickup in the tank, routed line to a pump mounted on the fuel tank support, then push lock hose to the inside of the cab.

The heater is mounted on the rear trans tunnel. The exhaust is routed out the rear. I fabricated a secure means of supporting the exhaust and routed it out behind the cab, next to the transfer case, and rear of the fuel tank.

The standard coolant heater, even when installed in the cab, really isn't quite enough so I looked at the arctic heater options. Based on the discussion on this forum, the Benmar seems to have a better track record. As it turns out, there is a 20k btu Benmar heater available from the usual...

I have six of the nice fuel pumps that were on ebay several years ago; not an issue. I can use the fuel level switch/ relay to control which pump is on. What I am wondering if there is any technical negative to feeding ~7psi to the PT pump.

I have an M818 with NHC250, is there any reason not to install M35A2 fuel pumps into the M818 tanks? I realize that the opening in the tank needs to be enlarged but it seems that supplying pressurized fuel would be beneficial. I already have all the parts so cost is not an issue.

I really like the electric wipers with the 14" wiper blades.

In short, NO. There is a great book about Allis Chalmers (Plow Peddlers) wherein the author discusses this in words that I can't put on this forum.

I am in the same situation and bought the tool to remove the tach drive assembly. Once it is out, do I simply press the old shaft out of the gear and press the new shaft into the gear?

For the onan, I used the same ferrule as the multifuel. Unfortunately, to get a fitting, I had to cut one off a spare onan injection line. I never thought I'd need a generator where I live but we lost power last summer during a massive storm. Went from daylight to black as night in the time...
