Yep that is one bad spring. I just make sure when taking off the retainer ring I am not facing the can. I work with my body / face off to the side as much as I can be but still be able to reach the band clamp nuts with my ratchet. Then once the can cap is off I treat it like a loaded weapon...

Yep we have a pressure relief valve on the secondary fuel filter and a over flow valve on the head. The over pressure would have to be set higher than 70 psi. The min. working pressure of the system is 60psi. The over flow always flows because of the hole in it. Here the over pressure valve does...

In this case where it is the service side and not the parking brake side will make it easer. Air up the truck till the air dryer pops off and you have full air pressure. Have you cage bolt handy and nut working free. Flat ground and wheels chocked enough so truck can not roll. Release parking...

Yep got to be careful working with any air brake chamber. Here looks like it is the service diaphragm so you could cage the brake spring chamber and change out the service diaphragm. Problem is most of these trucks have never had any of the diaphragm's changed so my self I would do both to that...

Good question. Did they change the IP? When the FDC is still working the smoke cam and droop screw if it has a droop screw are set for the emergency fuel listed. When the FDC is disabled they would be out of adjustment. After FDC bypass we most of the time have to turn down the fuel by way of...

Yep not all pumps had droop screws but they have a smoke cam. Did not look in TM but believe the degrees were set different if my memory has anything left.

Since the FDC is bypassed the droop screw will just change the main fuel adjustment ( twin nut ). If you want more fuel now do the main fuel adjustment or twin nut. Just be real careful and do not let the inner nut turn at all or the stud will break. Need real thin wrench for inner nut outer jam...

Myself whenever any 809 series I had and was known to run but I then had problems with starting I would first run in the thumb screw. If that was not the problem then I moved on. PS, I always check the emergency stop was pulled and not reset.

Well just glad it was something simple. If you still have it the old rubber gasket it is a reuse type on the canister so keep it. Had a friend that need one a long time past and I just happened to have one and gave it to him.

Was not there a problem like that if the button on the high / low leaver stuck in the pressed position?

What rubber of the two did you use? You did remove the old rubber gasket off the engine?

Yea had the 8V92 rated at 475 in one of my triaxles dump trucks. Love to put 20 tones in the bed and run.

Myself I also remove the plug from the throttle shaft and check / change the PT filter.

Do you do a HMMWV or something else MV related. Yea the bull stuff has changed here in FL. a few years back. Seems like HMMWV's are getting branded titles for offroad only and the others are getting a branded title for road use but just like the old antique tag only used for display aka shows...

Welcome and have fun with it. I only looked at the pics as black font on green background is to hard for me to read.

Sorry to hear and RIP Dave. Had the pleasure of meeting Dave at the Ga. rally and him fixing breakfast for anyone that was hungry like me.

Yea my 60 series four stroke has the restricting orifice on back of head and return line. The nice thing on my 915A2 they installed a rubber ball primer fuel filter block. I always pump up the ball before I even try and start.

Seems like most everything has been covered. Yes as long as the fuel pick up / line up to the fuel pump and fuel pump is working then we go from there. Ever DD I have had / worked on the fuel filter blocks after the fuel pump had two inlets and two outlets. The correct primer pump that was...

Sorry something went wrong last post. My info has ADIS and the problems have been worked out. Bendix Air Dryer Problems Could Cause Low Brake Air Pressure - Safety & Compliance - Trucking Info. On a side note when all else fails follow the directions has always worked for me.
