Hi all just trying to finish up my Optimizer build but I can’t get a good compressor. Bought 2 new Murray compressors and both were bad, What are the odds of that. Both of them started screaming right out of the gate when I jumped the pressure switch. The first one I didn’t let it run long...

Thanks guys for all the info. I was just worried about blow by oil getting into my new turbo. I think I’ll try the stock set up and see how much oil gets into the turbo. It shouldn’t have a lot of blow by it’s a new engine. Thanks again.

Hi all, I’ve combed through all the posts on this subject and boy there are a lot. I can’t decide how to do it. CDR hose routed to turbo inlet tube (factory )? Or the hose routed to the turbo outlet at the upper intake, would there be the right amount of vacuum to operate the CDR properly? Also...

Hi all finally got the repaired IP back from Quadstar installed and running. They informed me the rotor was install backwards. Repaired it and resealed it and bench tested it. I have the timing set at 3.5 and TDC Offset at -114. I tried a couple of times to get the Offset between-0.25 and...

Hi all got the sensor back in. Took the o-ring off like you guys said and it went all the way in. New o -ring fixed!! I was way overthinking it. Thanks for all the help.

Thanks guys, yes I wondered about the o- ring. Believe it or not it’s still pliable greased it and lightly tapped on it. Yes I did a depth measurement it’s about 5 or 6mm from going in. I do believe the shaft w/ the wheel on it is raised up from lowering the trans. w/ the drive shaft still in...

Thanks guys, here is a step by step that might help. Broke sensor hold down bolt. Removed sensor Removed trans. cross member lowered trans. driveshaft still in. Removed six bolts that hold the case to the auto. trans. adapter. Trans. in neutral, transfer case not sure, had to take the linkage...

Same sensor I pulled out. It’s not a new one.

hi all I didn’t see a section for transfer cases. I pulled the output sensor out of the rear of my BW4401 transfer case broke off the hold down bolt. Could not get to it so I removed the 6 mounting bolts and rotated the case down to where I could get to it and repair it. Rotated case back up...

Amen😎

Yea I just e mailed him and asked how about to go about shipping the pump. Thanks for the good suggestions. I think I still have the rubber caps also. Thanks guys I let you know.

Thanks guys for the help. I believe I will send it back and have it checked out. I hope he has mercy on me about the warranty expiring. I did send him an e- mail w/ that Stanadyne bulletin and that I hoped he would work w/ me. Haven’t heard back. I’m going to e- mail him again and ask him what...

Would I be able to tell if a rotor was install wrong on a newly installed remand DS4 IP if I opened it up? I believe you have to line up some dots or marks when installing the rotor. I suspect I have a bad pump and also by reading the Stanadyne bulletin #502R Section 5 on the last page. My...

If QS fails me I’ll open it up and check it. If I can’t fix it I’ll try to find a more reputable pump shop and have to buy one. And use this one for a core. At least I have a good running pump. Know of any pump shops that rebuild in house? Thanks buddy.

Isn’t the rotor one of the parts discontinued. Maybe they ran out of the good ones. Yea I agree that’s why I probably will send it to him in case he hasn’t seen it before.

Wouldn’t it be a good idea to send this to QS when they check the pump out?

Also found this. Both my pumps are 5521. It says the 5521pumps are for 00’,s . Mine should be an entirely new different pump number. Or am I missing something.

I was scrolling through Stanadyne service bulletins and found this: https://www.dieselplace.com/attachments/stanadyne-ds4-service-bulletin-sb-500r2-pdf.380602/ Go to section 5 engine diagnostic my truck is doing the exact same thing w/ the reman pump on and throwing balance codes. Won’t show up...

I just got done putting the reman pump back on and will finish putting the intake back on tomorrow. The reason I’m trying the reman pump again is that I might have had air still in the system the first time I put the pump on. I say that because I had forgot I left the drivers side injector lines...

Hi all, just got a reply from QS. He said the pump is technically out of warranty. I could send it in for inspection and they could see what they find. Said it would have to be torn down and resealed before even hitting the test bench $500. He did say he could work with me as much as...
