Stripping/rebuilding a Garrett GT series Turbo

flip49

I'm making this guide as there is not much online about the GT Garrett turbo's.

Ive rebuilt these turbos many times and this is the way I find it best and ive yet to have any problems

photos where taken while rebuilding a GT1752 with blown seals(bearings where perfect but replaced them anyway) and swapping the water cooled core with a air cooled core from a Astra GT15 turbo (which just goes to show how interchangeable GT turbo parts are!)

first of all strip the turbo... sadly I took no photos of this but ill explain, but if you look at the photos for putting it together you wont have a problem.

Ive tagged up a photo with numbers to help identify parts which should help here goes...

Really nice guide.
Is it not necessary to balance the shaft after putting a new compressor wheel on?
My 1.3 JTD turbo is leaking a bit of exhaust fumes from the variable valve shaft seal and there is engine oil appearing in the intercooler.

Might need this guide soon
