Oil Pressure has left the building.

[Recovry4x4]

Good or bad luck, I'm not certain. The other day I started the SECMish CUCV to be treated to a big red idiot light telling the idiot that there is an oil pressure problem. Today I finally switched out the sender but still had a warning light. Hooked up a gauge and confirmed the worse. Odd that it was working fine when parked. I hope to start looking into it later this week. First thing I'll do is pull the vac pump and check the drive. If that pans out I'll try running up the oil pressure with a drill. If all else fails, drop the pan. Crap, this isn't the time.

I'll just have to come down a tad before the rally worst comes to worst, and swap the motor out.

POst up what you find.

 

[Recovry4x4]

Just ordered a pump, drive and pan gaskets to have them onhand. If it looks to be more than I have time for, I'll just drive the bambalance. **** thing needs a 454 anyways.

You typed 4bt wrong.

I am coming over sometime after the 16th. Anything you need me to bring.

 

[Recovry4x4]

Perfect timing Doug, let me give that some thought.

 

[hndrsonj]

I'd try putting some oil in the motor.

 

[Recovry4x4]

Can't be out of oil, its still leaking. LOL, I did consider that though.

 

[2002ford]

I have several bad motors. Just let me know what you need.

 

[Recovry4x4]

Right now I can't think of anything but let me try to sleep on it.

Kenny, remember those two extra travel days you had by moving?.......well I guess you found a use for them.

 

[Robo McDuff]

Isn't this a nice action to do during the GA Rally?

Crud, a while back I had obtained a HMMWV oil pump drive. My plan was to insta this during the oil pump diagnosis and repair. Now I can't find the dang thing anywhere. This stinks.

 

[Recovry4x4]

OK, I'm slow. Finally pulled the pan today and I must say, I'm dissapointed. The oil pump drive is fine and I see nothing wrong with the pump, inside or out. I haven't pulled the vac pump yet but don't see how that can fail. Will try to reassemble tomorrow and hope for the best.

 

[cucvrus]

What part of the HMMWV engine is it that you need? If anything. I have several engines for parts.

 

[Recovry4x4]

Thanks Rick. I did get one from 2002ford.

 

[Tinstar]

I would still replace the pump if it's original. Your already in there.

 

[Recovry4x4]

I have a new oil pump on hand and it will be installed. I'm also removing vac pump and replacing it with a tach drive oil pump drive.

Tinstar, love the avatar Sir. 160th SOAR has been at the port many times doing training missions with a few SEAL teams. They housed their birds at my brother's hangar. Those guys bring new meaning to the word fearless.

Flew with them my entire Army Aviation career.
Best bunch of guys ever.

Of course we did have the best toys to play with.......

I am completely perplexed here. Thus far I can't find anything wrong here. Vac pump was just fine. Oil pump drive rod intact. This morning I spun up the old oil pump with a drill. Cupped my hand over the pickup and it sucked like normal. I did open the pump up and looked fine.

Installed new pump, drive rod and buttoned it back up. Tapped my temp gauge into where the sending unit is and preoiled. Pressure came right up. Installef oil pump drive and lit it up. We have oil pressure again. Gheez, guess I should just be happy.
