2 different style compressor backing plates from 83?

[nothingman]

I've got two 83 t-type turbo setups, I've attached some pics of the compressor backing plates. The one pictured on the left side appears to be trashed... I was just curious what the difference is and if I'm using the correct backing plate for the bearing i have or if I need to find a backing plate like the one that is broken?

sorry i meant carbon seal instead of bearing

The backing plate on the left is of the floating type, the one on the right is a one piece seal.

the backing plate on the right, is the correct one for the type of carbon seal you have.

right on thanks, i guess i lucked out this time! only thing now is installing the carbon seal... i guess it has to be pressed in, does anyone know an easy way to do it without damaging the seal?

An arbor press is the best. A hyd press could work but you won't be able to feel if its going in straight. Don't attempt to drive it in. You will break the seal. Bring it to a machine shop and have it pressed in

thanks bison, problem is I don't have an arbor press although i've heard it can be pressed in with a vise but i'm worried about pressing it in with a vise correctly... i did a little searching online about it but turned up nothing, are there any special instructions for pressing in the seal or visual aides? otherwise i can take it to a machine shop but i live in a small town and i'm worried about the machine shop messing it up...

You have to have a feel for the press. I've been pressing bearings and seals on and off for years so I can easily tell if everything is going smooth. If it is it will go right in. I use anaerobic sealant at times also because it lubes the surface and provides a perfect seal on the bore once pressed in

thanks bison yea thats kinda why i'm leary about taking it to a machine shop around here i don't know how much experience they have... nature of the economy i guess hiring folks not qualified, i've had machine shops mess up my stuff before. a friend told me a good way is to put the carbon seal in the freezer for a couple days then heat the backing plate in the oven for a bit, place them in a vise or c-clamp and ease them into each other... i do have some anaerobic loctite stuff(not sure of the exact name but i think you recommended it to me in another thread) that i can apply...
