Still looking....I need the v8-300 manual thst is with the Jake stuff......

The Museum has 2 M20's and 3 half tracks. Both of the M20's have not been touched and the engines are grey. Two of the half tracks have grey engines, I am unsure of the 3rd one, it is a French return, but IIRC, the engine is green. The M8 and scout car are gray. Never seen a clean gear box so I...

Here's a little update. The pig system came in a couple of days after it was ordered. This, but not a Melling, https://www.jegs.com/p/Melling/Melling-Pre-Lube-Engine-Oiler/1398393/10002/-1 I pulled the oil filter can. Funny thing, the filtration is a scavenging or bypass type, meaning it...

9L ISL is around 550 CID. HP varies, as stated, L9 380 would be 9L,(549 inches), 380 HP. The C series, weather mechanical or electronic, is 505 CID or 8L. :???: Don't we all know SOMEONE here that is putting one in their 5T? Clint......:burn:

283? You mean Chevy? Nary seen a 283 Cummins. Is it inline or V config?

Simple stuff before you go interrupting fuel systems, It takes a bit to make things run right after opening lines and such.

Simple checks first, 75% of good trouble shooting is easy stuff.

Do the checks for low power....FSOV pulling in the proper distance, throttle lever to the full throttle stop, the AFC line in tact and connected, no open holes to atmosphere in the charged air, the turbo actually spinning, then pressures and restriction. Did you have your pump repaired or get...

Come on out, we have a set of stairs!

OR, more simpler things first, look at the fuel shut off, if it is broken, it wont have full fuel internally, also check that the throttle lever actually goes to full throttle stop, and, look at the AFC sensing line/fitting, the like to break at the fitting at the head and the steel bung in the...

That is a pressurized point in the pump, keep in mind, at idle it is just flow, but, the symptom you get when the throttle shaft leaks is "air in fuel". It will be kinda hard to start, slow to build RPM and the RPM will hang when the throttle is replaced. It is a .20c o-ring leaking, but the...

It is basically 2 separate pumps. The main P/U in the sump pulls the lube oil and supplies the engine oil pressure. The scavenging system, when in high angular operation, pulls the oil from what is the front, but would be the rear of the vehicle and discharges it into the sump. The scavenging...

The governor end of the pump has a sensing line that goes to the manifold, the manifold pressure pushes on a diaphragm which in turn moves pieces parts in the governor end to allow the pump to supply full fuel. If you delete the turbo, the engine will smoke horribly. The cylinder heads have...

Been a bit since I visited this thread. There are indeed bladders on the vent and hand pumps in the drivers area. Today we looked at one of the road wheels on the LH side. If you look at pic four of post 1, you will see the rear road wheel sits higher than the rest, thought maybe a broken...

Today, I re installed the main I removed, with the shims, the book I found indeed mentioned shims, measuring end play and rotation force. Since the rotation force cannot be measured as is, I just put the shims back into their original spots, kind of funky to me, .010 on one side and. 015 on the...

Reading is a wonderful thing. As I was going through the Hercules engine rebuild manual I came across the lube system that we have. It's a Scavenging oil system. It all makes sense now!

Okay, today is my Friday, so I did some searching in the libraries here at the Museum. I actually found two books for the M8 and M20. Turns out the oil pump is correct. Still not getting multiple pickup points, but found that it was missing some pieces inside namely, the two seals for the pickup...

This is what I have, the big ugly monstrosity with the two pickups coming off of it is the one that came out of it. The rusty one is one that came out of an industrial engine in a Searchlight generator. So I'm not understanding the multiple pickups. We do not have a manual for it at the Museum...

JXD, don't know why I put A....fixed it.

Does anybody out there have an oil pump out of the Hercules JXD out of a greyhound? The M8 at the museum has had a hard start condition since the last time it was parked. I dropped the oil pan today and found the whole inside of the engine dry. The oil pump is really funny it has 3 inlets on it...
