I have just bought a used hypermax turbo kit. There is play in the bearing I need to rebuild it. I am having trouble finding a kit for my turbo its a Garrett And I have the part and serial numbers. Part# 465124 5004 And the serial# SL 0157 R . I don't know what modle it is the Garrett has many differrent modles and I cant find the one I need if anyone knows if would be great. And does anyone know of a turbo rebuilding shop around the boston area, were I could get the rebuilding kit from. I have never done a rebuild on a turbo before but I heard that its a pretty straight forward job. Thanks

David 85 I think rebuilt his turbo and a couple others the same places ought to have the parts.

 

Actually no, my turbocharger was good enough and I am still using it as I bought it. I think Ghunt did rebuild his though.

What sort of play are we talking about here? Side to side is fine as long as it doesn't touch the housing or leak oil. Play in and out is what's not acceptable.

I believe the turbo you have is the garrett T04B, but a generic T4 kit should work for you if it does indeed require a rebuild.

 

Havn't you got that play thing backwards David 85.

 

Nope David has the play thing correct.

Some side to side play is acceptable, there will always be side to side play especially with no oil in the housing. There has to be some space in there to let oil get into the bearings.

In and out play is bad because that means your thrust bearing is shot, and it'll chew up your turbo quick.

Anyway, yes I did rebuild mine, but I've also done a few (thanks to the ones on my Thunderbird constantly eating oil seals).

Any kit that is listed as being for a T3/T4 turbo will work. All Garrett model T3 and T4 turbos (and the ones we have are T3/T04B hybrids) use the same internal parts- bearings, thrust bearings, ring seals, etc. MAKE SURE you get a kit with a dynamic compressor seal...there are three different kinds of seals that were used over the years, so you don't want to get the wrong one.

Also, you don't need a "complete" kit that has bolts and compressor housing clamps and all kinds of other stuff in it unless your turbo is really trashed (and if it was that bad, it probably wouldn't be worth rebuilding). You should just need a "basic" kit.

If you want to do it yourself, get an exploded parts diagram or some sort of how-to to help you along. It really isn't hard. The most essential thing is that you mark the position of the compressor wheel and shaft before you take it apart, unless you plan to have it rebalanced anyway when you put it back together (which isn't really a bad idea honestly). Beyond that it's pretty simple.

I don't know of too many turbo shops offhand, but Gpop's Turbo Shop rebalanced a turbo for me awhile back, did a really good job and had a pretty decent price on it (I think $90 for a balance job including return shipping).

If you have any other questions let me know, like I said, I've done a few turbos myself, the only tricky part is making sure everything lines back up when you put it back together so you don't throw the balance off.
