ok so I need to reclock this huge turbo for my jet engine. I dont know what it is, its a huge garrett. Anyway the exhaust housing is held on with bolts; its not a v-band.
I got the bolts and retainer pieces all off but the housing is still siezed solid to the CHRA/center section.
Ive tried soaking it in PB blaster for days, no luck. I tried heating it up a little bit with a torch, but I didnt try for long because I had a couple questions...
where should I grab on the turbo to hold it in place? Ive been clamping it in the vice by the T6 flange/foot. Where should I hammer on to try to break the CHRA free? Obviously im going to be careful with the aluminum compressor housing, but how likely is it that Ill crack/wreck the cast iron turbine housing? Do I need to be super careful? Remember this is a hugeass turbo off a detroit 12v71-something, so the housing has some mass to it.
Im using a block of wood...Im assuming using a hammer right on the hot side housing is bad...
Its tricky to pound on the housing because when its gripped in the vice by the housing, I have to kinda pound on the CHRA to separate it...(obviously if the hot side is clamped in a vice, pounding on the hotside wont separate it)
if I make some bracket that bolts to the oil drain flange holes and pound on that to try to "rotate" the CHRA, am I going to damage the CHRA easily?
Any other tips? Im going to keep heating it up more and just keep trying I guess...im almost tempted to take it to a truck shop and say "heres 50 bucks, reclock the housing!". Im sure they would have some jig or widget that separates it easily without damaging anything...
