Installed a 24 Volt, 3-8 psi fuel pump, bypassing the PT pump, to charge the fuel rail prior to starting and diagnose what my RPM issue is. To recap she's hard starting and I can't get her over 1000 RPM. Also addressed a bent nipple on the fuel shutoff valve that caused a misalignment of the...

Installed one of Big Mike's engine block heaters. He advertises it as "ENGINE BLOCK HEATER FOR M809, M939, AND M939A1 MODELS w/NHC 250 CUMMINS - EBH250". The instructions say it's for Cummins (855 CID) engine series with side plate, which I assume covers our engines. The heating element on my...

Took Juanprado's advice and bent back the wings to the radiator petcock to take it out with a socket wrench. Found that the petcock on my spare fuel/water separator was the same size...saved a little cash.

Had a similar problem with my M813, turned out to be a rotted out pick up tube in the tank.

What's the amperage of your stereo system? If the total amps are more than 70 nothing will work. More amps in a converter are better, your equipment will draw what it needs.

I have an M813, not sure how many models have this part or if this post would be better served in another forum, but has anyone found a cheaper civilian replacement for this valve? The lowest OEM valve I've found is $175. The 1/8 NPT stem on my valve is bent, doesn't line up well with the...

May have figured out my RPM issue. First a recap, after an oil change the shutoff solenoid started acting up then I couldn't get the truck over 1000 RPM...how any of this is related is anybody's guess...the diesel Gods are restless. First I tore apart the fuel system, replaced the filter and...

Welcome back to the Green Metal Psychosis...

Welcome from the 5 Tons.

Tell me it wasn't you who bought it JD? Your kids are gonna kill you...

What ratio did you use?

Count me in.

According to the data sheet it does contain Nitrites. Contains Nitrite For Exceptional Wet Sleeve Liner Cavitation Protection.

Modify the spring, instead of catching the bolt above the nut hook it to the bolt between the nut and the bracket.

Place parking brake lever (2) in release position. Turn adjusting cap (1) counterclockwise to fully disengage parking brake. Loosen nut (10) and turn adjusting screw (11) to set clearance of outer parking brakeshoe (9) and brakedrum (8) to .015 in. (.381 mm) (A). Tighten nut (10). Loosen jamnut...

The inner and outer shoes are set at .05 or 1/64 of an inch with a feeler gauge, can't remember the TM but here's a video I produced on the subject with illustrations from that TM.

Found a vice mounted rivet tool from DJS Tractor Parts on e-bay that did the trick on my M813 parking brake, had to modify the setting striker to fit my vice.
