Engine/Transmission (1994 - 1998) Fuel Shutdown Solenoid.

[radixr]

I took my fuel shutdown solenoid off to replace the rubber boot (and switch from a #11 to #10 plate ). It appears that I have lost a screw that helps secure the solenoid in position. This screw points toward the front of the engine and must be what makes the solenoid resist rotation when moving it out of the way to remove the AFC housing.



Does anyone know the size of this screw? It's the same thread size as the other two screws holding the solenoid onto the AFC housing but I don't know what the length is.



While I have the solenoid off, is there anything else I should do to it besides replacing the rubber boot?



Thanks, Dave (a. k. a. , radixr)

Sorry I didn't find your question sooner.



That PITA screw is 2" (2. 014" exactly from the end of the head to the end of the bolt).



Not too surprising that someone left it out - i've been tempted many times

If you find a replacement for the rubber boot, let us know where you found it.



I just installed the 3K GSK and wanted to replace the boot on my solenoid but neither DC nor Cummins listed it as a part. You have to buy the solenoid as an assembly.



I really appreciate the manufacturers' concern for us consumers in the way they simplify our lives. If anything breaks, just order a new assembly for whatever outrageous price that they want instead of suffering the inconvenience of removing and replacing a simple $2. 00 rubber boot and the nylon tie that holds it in place.



My boot is cracked at each end and should be replaced.

Since I couldn't find a replacement, I coated it real heavy with liquid rubber electrical tape and put it back on.





As I recall, the three bolts holding the bracket to the engine are all the same length.

rubber boot

You will be happy to note, that the $2. 00 boot you refer to cost 19. 95, from cummins. How ever you can invest a couple dollars and buy a tube, or steal your neighbor kids bike and take out the inertube and cut to size and install two zip ties, and walll-a cheap effective repair. its been done and it works.

Thanks Marv,



I called two dealers near here and Cummins Northwest in Portland and they all told me the boot is not a separate part.



Did they give you a part number?

I did mine the cheap way. the boot number is listed in previous posts. someone on here had them or was looking for a good source. don't recall who.

Thanks, KRS. Oo.



Howard, I am going to use the bicycle tube fix also so I don't know the Cummins P/N. :{

Larryb has them: http://www.fostertruck.com/dodge/default.htm

Hmmm,



Technically that bolt is listed as a M6 x 1. 00 x 45 with the '45' being the length of the shank in millimeters minus the head.



My Cummins part book does not have a listing for the boot, but it says that the solenoid is made by Syncro-Start so maybe their parts book would show it. I don't have one of those books.

available boots

The mechanic where I have work done on my 96 gave me a boot that came off the larger cummins that are used in school buses, they service quite a large fleet and solenoids are replaced occasionally and as most cities have school busses this might be a source. I ran mine without a boot for about 250,000 miles with no problem so I guess it depends on where you live. Stormy

Larry B. wants $26. 75 plus tax and shipping for his.

I think I'll get me a bicycle tube.

I have a boot I don't need since my solenoid fell apart when I tried to replace the boot. If anyone needs one I'll sell it to them.

 

[radixr]

Steve,



I don't know if your solenoid was good or not before you tried replacing the boot, but the boot is what holds everything together.



I'm thinking maybe I will use a zip tie to hold the plunger in place while I fasten the ends of a piece of bicycle tube to the plunger and solenoid with more zip ties.

 

[DPyles]

huh?

What screw are you guys talking about?

I just took my solenoid off and inspected it and I do need a boot.

I took out the two retaining screws that mount the coil to the bracket and I did not see anything else that held it on other than the little hairpin clip that retains the plunger to the fuel valve.

I did not see any other bolts nor do I think that there need to be any.

How could the thing rotate when connected to the fuel valve?

Some one please enlighten me as to the mystery screw.

Oh and I also replaced the rubber fuel lines form pump to steel lines on the bell housing. I would like to meet the S. O. B. that designed those to congradulate him and then kick his a$$ for him!!!!!!

 

[radixr]

dpyles,



The screw in question is below and behind (towards the firewall) the two screws you removed. It points towards the front of the engine and goes thru a small sleeve welded to the bottom of the solenoid bracket. It only rotates enough to clear the top of the AFC housing.



The Cummins P/N is 3901937. I ordered one from my Cummins dealer today.

 

[SteveMiller]

yeah the solenoid still works but I believe that it may still be damaged from the boot being so bad for so long. My truck was having a lack of power and the new solenoid seems to have fixed it. I believe the old solenoid wasn't lifting all the way anymore and it was cutting off fuel.



So if anyone needs a solenoid and/or boot you might want to PM me. The old I have may work for someone else or at least parts of it. The new one is pretty cool though. Its bigger and has a new bracket along with a heim joint type end. Of course its also right around $300.
