Turning up the maximum fuel is something that should only be done if you have an exhaust gas temperature gauge. The plungers rarely get stuck to where it limits fuel. Smoke is not a good indication of maximum fuel, by the time you get smoke, you could be well over 1200 °F.

H4 LED conversion was why I went with Rampage H4 housings. They came with H4s so it was under $80.. They are so good I have not looked for the best H4 LEDs. They offer excellent low beam illumination for off road with no dark spots on high beam. I guess I should take pictures.

Indirect injection diesel is already very clean once the engine is at operation temperature. Diesels run a different thermodynamic cycle, on the P-V diagram, heat addition is a constant pressure process, any bang is due to short injection window at idle. At maximum fuel, the injection window...

Tach installed and working. For switched power tap, I used the PTO governor power lead as it is close, switched and fused. The alternator signal is off the glow plug module, brown wire, terminal A. Then I finally installed the heater core valve controller, a DPDT switch with end point...

The most restrictive portion of the stock exhaust system are the crimp bent head pipes. Here, the peak velo city is highest, bends severe and high inner pipe roughness. Replicating these in mandrel bent stainless is your best bet. Remember, this engine spins at 3600 rpm..not even 400 standard...

New, larger tires on 8.5 inch wide replica rims cured my death wobble. I had a failed belt on Commercial TAs so that was an issue too. Cannot say enough about having 12 kW of power after our Valentine's Day blizzard and 96 hour power outage. Needed the 4 wheel drive 90% of the time.

I made the calibration tool..still have it somewhere in my empire of dirt. The original valve on my 1031 was completely shot, late shifts as vacuum to the transmission was nothing. Even improperly adjusted, the new valve was much better.

Could be a worn engine, easy enough to compression test both cold and warm.

The dynamic timing is advanced by transfer pressure acting on a piston. It is retarded by preset spring force and the action of the face cam through the lever on the passenger side of the pump. What could be happening is the fit of the piston in the bore has worn out, causing excessive bypass...

I went H4 halogen Rampage Products 5089927. It is DOT approved, should be fine for the UK. Much better beam. Sealed beam units with glass reflectors have front corrector plates because hot glass removed from molds distorts as it passes down the cooling oven. So they correct distortions using...

When the engine is warm, putting power to the solenoid should make it clatter. That glass ball is a check valve, spring loaded. When the cold timing advance is energized, that pin holds the glass ball open, preventing case pressure from the spring. This loss of case pressure advances timing...

Ok, if you can put power to the cold timing advance solenoid (the one inside the injection pump) and it runs better, there is a good chance the timing chain has worn, creating sloppy timing. Or it could be a worn pump not making transfer pressure. The transfer pump pressure rises with engine...

Making addition to the dash bracket originally for the radio. Currently it has the rear view camera and the combination volt/amp/power/energy meter. I installed a heater control valve on the hot coolant going to the heater core. Just a 12 volt motorized ball valve, stainless and Teflon...

Installed a new Spectra brand heater core. These have a few quirks since they don't seal to the air flow. Using HVAC rated aluminium tape and high temperature urethane weather seal, I got it done. You need to remove the inner frame too, two more screws to remove. Then test fit and see where...

Definitely needs an external regulator plus the connector. Probably needs a larger crankshaft pulley to drive it at enough speed to obtain rated output. Getting 100 amps at 12 volts from a single 3/8" v belt is about the limit of power transmission. That unit uses two belts, each one 1/2"...

If it shifts the same with light accelerator pedal or mashed to the floor, it is most likely to be the injection pump mounted vacuum regulator.

Only the starter and glow plug feed are 24 volt. All other parts are 12 volt common to the civy models. All 12 volt supply starts at the diamond shaped junction block on the firewall. This is your 12 volt supply for the relays. The 12 volt switched from the headlight switch triggers the...

I towed mine with a medium tow bar set behind a F250 Crew cab. Rear driveshaft removed, transfer case in neutral, hubs unlocked, batteries disconnected, key in and on run position. No issues, just keep speed moderate and huge following distance. Get magnetic mount tow lights. This was 1200...

Adjusting the regulator is on page 3-176 of the -34 TM. The vacuum pump should draw at least 20 inches of mercury. That is about negative 12 PSI. Stronger vacuum than most engines at idle.

I had an Equus coolant temperature gauge. Unreliable to put it mildly. And I didn't like the non linear scale either. When I finally got a good thermostat, I pulled it out. I wanted something more than a simple voltmeter, found a combo ammeter voltmeter digital for under $20. Works like a...
