Ok, I thought I had an issue with the IPR or HPOP. Turns out, the 17* I bought blew the oring between the line fitting and the HPOP.
But before I knew that, I got a new IPR and HPOP and started tearing it down today. I have everything apart except the 18mm bolt that holds the gear to the pump. When I loosen the bolt, the bolt just turns the pump backwards.
I spoke with Marc today and he suggested that I loosen the rear bolts and pry the pump back a bit to put pressure on the pump. That didn't work. My question is this;
Is there a way to lock up the HPOP to remove the bolt??????
I tried replacing the oring and putting everything back together, but even the new oring just blew out. It seems this pump as seen better days, I think the fitting is stripped.
I've never had this problem before and no one else has seen this either. I need to get the truck running ASAP.

I have a question. Can you access the flywheel easily??? And if so the only thing that comes to mind right now is to get someone to take a long prybar and wedge it between something and the starter ring and hold it there while you attempt to loosen the HPOP bolt. or put some bolts in the dampner and put a bar inbetween the bolts and hold it there while you're attempting to loosen the bolt. Lemme know if this works????:thumb:
I just to the Bob Riley at Dieselsite. He said the loctite is causing this problem. I will have to remove the reservoir and clamp down on the shaft with a channel lock.
If you have an angle head drill, cut off an extention, put the extention in the drill with the socket and crank it. I made a hpop driver out of a bolt and got oil pressure with the angle head drill spinning the hpop.
Yeah I know the bolt goes through the gear. I'm talking about having someone hold the flywheel at the back of the engine. or putting bolts in the threaded holes on the vibration dampner and holding it there. By putting a bar at these spots you can attempt to keep the engine from rotating eith way, while trying to brake the bolt loose in the HPOP. If that doesn't work pull the reservoir access off and wedge something between the gear and the reservoir housing.
I don't think I'm being clear. The mount on the HPOP for the gear is smooth. There is nothing in the engine or res. housing that is turning, except for the hpop.
Hey Dirk,
Do you need an extra set of hands? I can come over tomorrow night. I get off work at 7pm, but I don't mind going out there to lend a hand.

ive never heard of the bolt spinning, to me the pump shaft is usually to tight to be spinning with the bolt , are you using a impact on the 18 mm bolt or a hand ratchet , if using a hand ratchet , better get a impact on it and let the torque overcome the bolt pressure
Ok dude, I just looked up the pump online. In the back of the pump there is a lock ring that holds a cover in place. Remove the lock and cover. there should be something behind that cover that you can wedge something into to hold it while trying to remove the bolt. I'm not sure on this, b/c I've never looked behind the cover before.
Or as Scuffy said, you'll have to get an impact in there to remove it. I had thought about that already too, but wasn't sure you had an air gun.
Not sure how this pump works, but if it is like a gear pump. Try and feed some rope, or some type of heavy string into the proper side of the pump. Feed or discharge, to try and jamb the gears and stop the rotation. Also dont be afraid to heat up the bolt itself (hot air of coarse is much safer than the fire wrench,yet half the fun) to try and soften any loctite and when all the planets finally aline give your wrench a sharp whack with a hammer and see what happens....my 2 cents
ok, gotcha. hmmm, then about the only way you can get it out is by using the impact and using fast trigger pulls back to back to try to dislodge it. Or the alternative, Find someway the cut the head of the bolt off. Sorry man, i'm all out of ideas right now.
like i said before , ive probably put 500 plus pumps on , and never had the pump turn and not allow the bolt to come out , i would get an impact on it and bump the impact and see if it will move , there is no way to hold that pump or shaft to get it loose
TXBroker's wife came over today so I could use her truck to haul my big compressor to the house. Everything went great, cept for the fact that I can't find my 220v plug to get it working! (this sucks). Thank you very much Paul, and tell the little lady thank you again from me!
Tony Wildman will be over around 4 with a 110v compressor setup and a extra set of hands. Hopefully I can get the bolt out. When the both is out, I think I can get it back together, oil pressure built up, and have it running in 1.5 hours.
BIG thanks again to TXBroker (and especially his wife) and Tony Wildman.
Let us know! I got mine off by putting a 24mm socket on a breaker bar on the crank nut to stop it from turning over and then I used an 18mm on the pump nut.
Deal is done. Tony Wildman came over with his air compressor and with my 3/8 impact, it came right off. I guess I lucked out with the other hpop's I've done by hand.
Lesson?
Listen to Scuffy and not screw around. Use the impact. Once again, major thanks to TXBroker (and wife), Tony Wildman (It's good to have you about 1 mile away), Marc (for taking my original call), and everyone else for the advice.
