It takes a "special" tool to raise the idle. It is done through the gov. end of the pump

The injectors on the NHC cannot stick open. They aren't pintle style, and are manually activated/operated by the camshaft. Cummins makes a product that works VERY well. It is normally used pre overhead set to remove carbon from the metering and tip area of the injector plunger so when the...

^^^ THIS. If you over concentrate the sca's you can cause continuing issues with the cooling system, multiple w/p failures, plugged oil cooler, radiator and aftercooler...if it has one, heater core, overheat issues. It makes the inside of the engine a mess. I have seen the block coolant...

Patience and tenacity will be your friend. Turn the shaft backwards.

A bit of PB blaster over a few days and love taps on the yoke SHOULD loosen it up unless the shaft holes have elongated and dug into the yoke. If thts the case, again, the PB Blaster and a hammer to try and turn the yoke backwards to align the holes.

Those pumps don't spin freely, they are tight. If the impeller is in tact, looks good in the pic, and there is nothing in the weep hole, it is fine. But it is your money. There are two types of Restore. One removes grease/oil/gelling and the other is a de-scaler.

CPL...Control Parts List. It lists the performance parts, pistons, cam, head, injectors. CPL identification has gone the way of the DoDo, ESN is how everything is tracked now in Cummins parts system, until someone come in with an engine made before 1980 :roll:

Nope, not on midrange engines until 2006 or 2007.

They look like this....

Give me your esn and i'll check if it a two stat build. IIRC, some vehicles with an auto trans had just one stat so there is a positive flow through the lower rad hose and trans cooler with the stat closed. That stat looks wrong and it should have have been in the hole on the left of the pic...

Talk about reviving an old thread! Way easier to pull the head and push the piston out than swing an engine. Don't hone the liner, it has a coating called "luberite" on it. If you remove it, the cylinder will burn oil. The cover on the side of the block is referred to as the hand hole. When the...

Air in the system is purged out by the vent line at the front of the cylinder head and deairiation line from the top of the tanks to the surge tank. The only similarities between the B series and C series are 6 in line cylinders. Two totally different engines.

That means nada, they are known to be "erroneous". Verify it with a known good one.

Overheat is different from cab not getting hot. The leak at the air comp line won't have an effect on the cab heat or over heat issue, it is just an annoyance. The seal there is only a 1/2 in id, 1/2 inch wide rubber sleeve, the nut crushes it against the fitting. Only difficult part is getting...

Which issue are you trying to troubleshoot? No/low heat to the cab or the high temp? You need to troubleshoot your issue BEFORE you start throwing parts at it. After reading your posts, the stats don't seem to be the issue...upper radiator hose get hot, that tells me the stat is working...

Don't forget to un pin the engine and flip the pump timing pin back around BEFORE you rotate the engine.

CUMMINS....geez. Two parts. TDC the engine, use the pin on the rear of the gear housing or the valve overlap method. That is engine timing. For the pump, if removed, remove the cap on the lh lower side of the pump at the governor housing and take the pin out, it is a whitish/yellow pin abouk 3/8...

What do you want, a service manual?

These will start and run well at idle with 28 in restriction thru the filters. They don't like to do anything but idle in a plugged filter condition. Easy things first, LOOK at things. Most of the time it is simple issues that cause no starts in these. And, if the pull in circuit is fubar, with...

There is an electrically operated solenoid mounted to the pump, 3 wires, ground, pull in and hold in. when you crank the engine, that solenoid needs to pull the shut off lever up in order for the rack in the pump to be able to go from the zero delivery to delivery position in the delivery valves.
