Swirl factor is cast into the head. On 2 valve heads it is marked on the head, cast into it, located on the intake side, front top, where an A/C mount would bolt, S1, S2 and S3. I forget about 4 valve heads.

Heads are different too, swirl factor is different. You'd need the pump gone thru and set it to an automotive style governor. Oil pans are a flat aluminum type, that would need changing to clear the front axle along with the oil pick up. So basically you would need a head, pistons, exhaust...

Looks good, hope you never need to use it!

Old stuff, half tracks, scout cars, wheeled stuff, parts are expensive, the tracks are getting scarce and VERY expensive. Parts for these two vehicles are drying up fast. As for tracked stuff, you should check with your local law makers, it is not possible to drive full track vehicles, rubber or...

The 3 M551s we have at the Museum all had a dragon on them. All were hand painted and different. The running Sheridan no longer has the dragon. All of the vehicles were recovered from NTC OPFOR, I believe at either 29 palms or Barstow, Ft Irwin.

OK, an update, Put the pump back on, sucked fuel like it should. Fired and ran OK. Smokes, it did last time I saw it run. Moved it into the back shop. and gave it a little love. Permanently installed a Racor pre filter to prevent the tri filter set up from getting full of crap. The lights didn't...

Bosch # 0402736842 is a 190 HP @ 2500, 475 ft lb @1600 torque rating with 11.5 degrees of timing, B series engine. Gov break....unloaded governor speed is 2825 to 2925 RPM. Is is an RQVK governor. Bad news is that the MW series fuel lines will not work on work on a P pump, delivery valves are...

OK, a bit rainy here today, soooo, had a chance to do some bench work today. I SHOULDA taken pictures before disassembly, but, most of the time when I get to "work" I just start on the planned project :whistle:. Today I tore down the replacement W/P for the M3 Scout car. The shaft is a little...

Maybe on its way to Gerald at WGT?

Maybe air, possible the 2nd valve was way worse than the original one. Air will usually cause a slow/hard start to start issue, low fuel in the galley, same as a valve that has a completely broken spring or the ball held open, that lets the fuel drain from the galley, a failing/low pressure...

In the MH, the double OD auto would be sweet behind the L.

Do you remember that you have a 5t that has another power plant waiting to go in it? Sorry, couldn't resist! Nah, not sorry :razz:

Yes, they do suck if they are the hard azz Cummins part, but there is a plastic one that is used too, WAY easier! Yes, turn the screw out slightly, like 1/4 turn, it will do ALOT! The screw is under the ball, the ball is a "tamper proofing" so the fuel rate can't be messed with. Be careful when...

Simp, SOME plugged/non AFC and most all PTG pumps are built with a shaft with no ball to drill out. I just pulled one from a V8-300 in the M123 and it had a solid shaft, it was returned with a solid shaft.

You are on the right track, just work slowly and be patient. I had this issue last month on a V100, heat to almost red hot, PB blaster, love taps, re heat then quench with cold water. Had to blast them when they came out. Re paint them and then use liberal amounts of never seize when you...

25-35 is normal, most new valves fall in around 30. It is somewhat normal to see the needle on the installed gauge to bounce around, like 15 to 30 at idle but the pressure should stay fairly steady when loaded. Restriction will cause low fuel pressure too. IIRC, 4 in suction restriction and a...

No, put the extension on 3 if you start at VS1-6 or A and do i3, v5. You will be setting the inj at the "top stop, zero lash" method, if the tag says .011 and .023, it should sat for inj setting TS zero lash. Bar the engine and watch, when the lever breaks, the mark will be around an inch or so...

Careful, if you do it wrong, you can cause damage to parts. You should make sure the accessory drive timing is correct before you get too far into things. If you set OBC, after you set your first set of rockers, let's assume cyl 1, put a socket with a 6 or 10 inch extension on the #3 injector...

I should point out that if the return is pinched off/plugged and there isn't an injector issue, and the engine lights, the RPM will start at an idle speed and fairly quickly increase to a very high RPM. This is happening because the return has no place to go and the engine is being force fed...
