Howdy everyone ,Brand new here so hello hows it goin...Now onto my problem I got a RAND 4000 DevilBiss 5 hp 2 stage pump that is knockin so bad you can not even yell at a person 5 feet from you and them understand any of what was said when that puppy comes on . So I have done some research and what have ya and only thing I can find out about ity is that its discontinued and good luck finding any parts for it. And yes it is a pain to try n find any wrist pin bushings for this thing. So here's my question do I go and buy material to make my own bushings and see what i can do about the scorn crank shaft in it ? Then having to find a gasket kit and all that jazz just to get it working again or do I just can that lightweight aluminum pump and plop some other higher CFM pump on it and if so what has everyone gone with ? Just wanting to stay on the cheaper side right now due to a work related injury that's got me out a while and the paychecks I get now are squat! I just am dead in the water here pretty much and would love to get some decent air again because the little 20 gal oil less thing I got from the neighbor needs to go back asafp lol .Any help or a point in the right direction would be greatly appreciated and THANKS in advance for your time ...

Hey buddy thank you for the reply the model number is RA5T80V1D and somewhere I got this model number for it not sure from where but it is SA2580V. I have been on all sorts of forums and diy fix sites no one really has any info on repairing the pump I have or a good replacement I can pick up . Because this is going to be the 3rd or 4th time in under 90 days I will once again be taking this POS back to HF...might have to start charging labor lolo... I really need my Original 2 stage pump back online . But thank you for your help and time for sure . And hell yeah still skating here myself at 40 bro
