Rajay e-flow turbocharger repair pictures....

Post by turbokinetic »

bHere are a few pictures for entertainment value!
My first natural-aspirated to turbocharged conversion was built around a Chevy 2.8 and a Rajay E-flow turbo. I got good service out of the system until a piece of a broken drill bit got in the turbo and ruined the compressor wheel. As we're all painfully aware, Rajay are out of production and parts are hard to find. Finally after several years, I found a new compressor wheel on eBay.

The broken turbo:
Image

The turbine shaft has a small wipe of aluminum from the old impeller. That easily came off. The bearing surface looks like new, in spite of the fact that I drove the car for YEARS with this turbo!
Image

Center housing all cleaned up.
Image

Bearing about to go in the housing.
Image

Bearing is in!
Image

About to put the thrust bearing washer on the bearing.
Image

Seal plate going on:
Image

Completed assembly:
Image

Flip over, and ready for turbine shaft.
Image

Install the spring and heat sheild.
Image

Turbine shaft is in! Lubed it with clean engine oil.
Image

Now the spacers for the compressor impeller.
Image

Impeller, washer and nut installed! New part looks so good in there!
Image

The housing has numerous raised gouges from the debris in the turbo. They need to be knocked down before the housing is placed over the new impeller.
Image

A few licks with a brake hone and they are smoothed down. There are some low spots but no raised burrs.
Image

Insulation ring on the center housing where the turbine housing sits.
Image

Completed turbo!
Image

Image

So that's the parts inside a Rajay E-flow turbo!
