I am attempting to get in touch with Joey about a T500 purchased from diesel power products.com
today I spoke with a rep cant remember his name but basically he represented that they no longer sell the T500 and offered to sell me a pump from a different company.
The issue here is that the T500 never generated enough oil pressure to start the truck.
I did move on to other projects for a time, but started back in OCD mode determined to get this thing running.
So, what happened was that I sent in my core unit, which was to be rebuilt and sent back to me.
I received the unit, but it leaked, so sent it back and Joey said it was fine.
Believing that the no start condition must be some other issue so far not discovered, I began a long and expensive journey into everything from injectors and injector sleeves, PCM
, wiring harness, turbo, even checked the compression to be sure that it was not just a worn out engine.
Anyway, learned a lot, took a long time, spent a lot of money…
Finally after breaking out Occam's razor#I realized that the only answer had to be that the T500 was not generating enough oil pressure.
Well I had to be sure, because honestly I was getting tired of chasing ghosts on this no start truck and one thing I have learned is that replacing parts is not the way to go.
The best thing to do is to test out the issue, prove it, then once you have a verifiable test, you can take care of business.
So, first thing, need a high pressure liquid filled gauge, but you also need a length of hose that is capable of containing high pressure hydraulic fluid in this case oil but you will also need to cap or block off one end of the HPOP
so you can test out not only each individual head, but also to test just the pump itself to see if there is an issue with the pump.
Well, after a good bit of testing and a order to an ebay seller I had the equipment I needed to test out the T500.
So, turns out that the T500 will not generate any more than 156 PSI
connected to both heads, 236 to one head or another, (verified that there are no leaks anywhere at all) up to 150 psi
, air pressure. which is lighter than oil
Anyway to make a long story shorter, I have now verified that the T500 purchased through Diesel Power Products.com Was in fact defective, some time did pass, but this pump never started this truck so there are Zero miles on this pump.
I suspect that there is an internal issue, but I am not prepared to take this thing apart, mostly because even if I did manage to get it apart without breaking something I do not have the parts to make a repair.
So, in order to contact Joey, I have to make at least 15 posts here and I understand that but I guess I will have to try to be somewhat diplomatic without intentionally trying to make someone angry, its not my intention I just cant find a way to make contact. Diesel power products, refutes, a warranty, states that there is a high failure rate and cannot contact Joey, thats not me saying that either. . . I am a little irritated that a company would collect 791.00 for a part that never worked and then run down the jobber instead of doing the right thing but hey if they can do that I can do this.
let see how many more posts do I need now.
