The tooth count is 98/24 the pattern is stub not full involute.

They are supposed to be together like that.

Except it doesn't fit the shaft worth a damn. I've bought one and I'm not impressed at all. The manufacturer claims it's this way on purpose to help "home gamers" install it. That's a load of garbage. If you can press the OEM one off you can put the other back on.

They will supply "slip fit" for easier installation for DIY-ers that had a machine shop remove the old one (then use a retaining compound on the shaft - for extra security), OR "press fit" for those who have access to a hydraulic press to re-install. Then of course, use Red Loctite 271 on the impeller retaining bolt.

@@mnsmtrs Mine is tapered and significantly oversize for a fit on a shaft that could be turning 60k rpm. If you can't press it on correctly then have someone do it. There is no reason to risk an off center impeller than can move on the shaft just to make it easier to install. That said, there is no reason ProCharger should not sell parts. There is also no reason to make those parts incorrectly. It just gives the whole industry of rebuilding a bad name. Just like inferior reman parts from the autoparts store. If they upheld the quality of the OE they would have the reputation generic drugs have. Same safe tested quality, less mark up and more value.

OK well everything we've used from them has been off the charts awesome !

@@mnsmtrs got any dynos? They say no.

Charlie, the belt drive side seal is a very common part. The high speed seal is a custom component that they do not sell.

Don’t waste your time with shitty procharger there’ll waste your money and do a shitty job . I have seen a dozen unit come back from this that’s half way done and charged them as much as a rebuilt engine .

Next time send it to Supercharger Rebuilds. Fast quality work and lower cost.

You just take the socket head screws out and evenly wiggle it off. The cover doesn't have an o-ring in it. The case does, but dont take that off unless you plan to dismantle the entire unit.

That was no noises and no highway speeds

I don't think I would be that worried the blower is splash lubricated so it's not receiving pressurized oil nor does it require it. Are you sure it's not leaking? It doesn't hold much and it would be hard to take half of it out.

Does a P1 have a 4.1:1 gear ratio like a P1SC? If it does then yes you can. There however is a problem. The genuine procharger D1 compressor housing cover is different. Aftermarket companies make a D1 compressor wheels that will fit the P1sc cover.

How far away are you? I'm in Florida. Did you unfortunately already crush the seal?

@@philipmacduffie7612 you have FB or IG?

@@philipmacduffie7612 where in FL? May have the same issue

I’m in Jacksonville.

It's not a gasket. It's a big o-ring

@@philipmacduffie7612 do you know where to get it?

@@AtticAZ superchargerrebuilds.com has them.

I'm not really set up to machine things like that to sell.

@@philipmacduffie7612 , could you provide the dimensions and maybe note if there are specific clearances or tolerences so I could get the tools made? Thanks!

Low speed seal should not need an expander. Reason I say "should" is it would be a hell of alot easer if you did. You just need to be careful to not cut the lip of the new seal.

Philip Mac Duffie I was actually able to replace it myself with out trouble. I just used a 32mm deep socket and rubber mallet to tap it in. 👌🏼

@@AtticAZ Great, a leaky low speed seal is the easiest problem to have. A leaky high speed seal is a total tear down. Again. It's not that hard to tear one apart, but the parts are expensive and like everything labor costs.

@@philipmacduffie7612, My P1SC1 just started making this sound. Sounds like a bad bearing possibly? See link. I know the bigger ones are “koyo 6206” but what about the other two sets? kzfaq.info/get/bejne/hJZynJB4ttXVYok.html

6204CTA A7 6205CTA A7 Two 6000 The GMN CTA A7 bearing basically doesn't exist. Finding a suitable alternate will be a challenge. Your P1SC-1 is likely already turning faster than a normal D1SC. Cheap 6204s have an inadequate speed rating; look for 50K rpm in oil as a start.

I could not justify selling tools. I made these on a manual lathe and I have tons of time in them. I could not sell tools for any sensible price.

Thanks for getting back to me. I'm hoping to rebuild my D-1SC without messing up the seals on the first try. Looks like these tools are the key to achieve that. How about selling me a set of drawings?

@@philipmacduffie7612 lend me the tools, i can blueprint them and get them back to you. I can give you half the sales price of any that we sell.

@@philipmacduffie7612 What about doing a CAD drawing and outsourcing? There HAS GOT to be a market now that these are fairly outdated. I know I'd buy the bitch, lol

Depends on what's wrong with it.

Philip Mac Duffie couple bad bearings. I took it apart to see what was wrong with it.

@@SINTAUR63 If the compressor isn't damaged, if you are that far why not swap the bearings?

Philip Mac Duffie Don’t know what I’m doing really and I don’t wanna f anything up to tell you the truth. lol.

You’ve got 4300 views. I’m sure there is money to be made if they are affordable. I suggest a cheaper metal

Bo, with 20 years in industry I know how to job out work. I'm not looking to be in the business of selling tools. I am certain making them in this design would not be affordable to most. There isn't much cheaper metal out there than 6061. It's about as free as it gets.
