I have an M813A1 that has broken two bell housings in the past year. Prior to breaking the first one, I plowed snow for many years with no issue. It’s all stock and the fuel pump hasn’t been turned up or otherwise modified. If my sprag isn’t working properly could it cause enough driveline...

My M1090 seems to have very low fuel pressure at the IP as it almost stalls under any load. It acts like it just isn't getting enough fuel. I've changed both filters with no change at all. It runs at wide open throttle while sitting still in neutral but as soon as I start to drive it empty, it...

I have an M1090 that's missing some sort of air valve that's located just behind and below the front service gladhand. There are two 3/8" airlines that have been connected to each other prior to it getting to me that appear to have once gone to the valve. The TM shows a front axle QR valve...

I need a part number for a new relay valve that sits on the inboard side of the left frame rail just opposite of the air dryer. A rebuild kit part number would be helpful too. Mine is venting air out the bottom. I've used the part number from the 24P but it looks like Haldex either doesn't...

The end cap of the pump came off in the tank. I put it back together and the impeller spins but it doesn’t pump any fuel. Is there suppose to be anything between the impeller and the end cap of the pump?

My power steering system is aerating the fluid to the point that its coming out of the vent within a minute of starting the truck and without touching the steering wheel. There are no visible leaks other than from the vent on top of the reservoir. Any ideas of the source of the air? I'm using...

I'm looking for a used OEM radiator or information on what else will fit in an M917 Dump. Thanks

I'm looking for a civilian part number for a u- joint for the front of the rear most drive shaft on an M917. Thanks in advance.

I'm replacing the front rear axle of the tandem assembly and need to know how to get the equalizing beam separated from the axle. The TM describes how it comes apart and that would probably work if it hadn't been over 30 years since it was built. I'm looking for realistic ideas of separating...

My M917 recently developed a noise like a knock or thump that is speed sensitive and only occurs during acceleration. Its also not noticeable until I get to 30 MPH. Any ideas on what it might be? My first thought is a U joint.

My 917 which was starting and running fine a few days ago will not crank over. I have at least 24 volts at the starter and it appears to try to crank the engine over but I can barely see any movement at the crank. Any ideas? Is there an easy way to bar the engine over manually to rule out a...

I can barely feel any air coming from the defroster vents even though the fan is blowing strong when set to direct the air to the driver or passenger. Even with the driver and passenger floor discharges closed, I can hardly feel anything from the defroster. Is this normal for this style heater...

I'm working on my M917 and can't get the back-up lights or alarm to work. The switch is in the correct position and seems to work however, there is no power to either side of the switch with the transmission in reverse. Does anyone know where the transmission switch is? I thought it may be in...

Having a problem with the PTO disengaging when I put the truck under load. Engages OK, but when I rev the engine to raise the dump or try to raise the bed while moving the truck, the PTO disengages. Any ideas. If so, how did you correct it. I've contacted Chelsea tech support and they're...
