Removing turbo inlet and outlet tubes
Posted by: Gwrodzhi ()

I am in the process of replacing my top fan bearing and I am trying to remove the turbo inlet and outlet tubes. I was just wondering if anyone has any tips or tricks especially on the inlet side.

Depending on how rusty the pipes are there are times where you will need an acetylene torch to heat them to separate. There are other times they are too rusty to separate and must be cut or broken apart.

Why don't you remove the turbo from the stand (4-bolts)? Once the stainless heat shield is off, you should be able to unbolt the exhaust outlet. No need to disassemble the exhaust.

I know I have done it without removing the tubes. I think I removed the turbo and loosened the stand. From there the top shroud can just be eeked out of place. I know someone here suggested this was possible and therefore I tried it.

Of course the stand has to be loosened from the cylinder head - it's on top of the shroud. The turbo end of the stand will already be loose with the turbo off. The generator/ alternator has to come off to; both for clearance and to get to the oil cooler cover. I just did a fan bearing on a '63 Sypder so it's all pretty fresh in my head. Definitely didn't have to mess with the exhaust.

I have done it on my 65 without pulling the turbo inlet tube apart. It wasn't real easy, but it can be done. I think I removed the blower pulley bolts first so you have some flexibility. Definitely easier if you inlet pipe comes apart.

Here's the "in process" photo from the Spyder fan bearing job. Note unaffected exhaust system.

Thank you for the info that is really helpful. I do have to replace the outlet pipe out of the turbo to muffler though as mine is pretty rusted and falling apart where it connects to the turbo. I have a 64 turbo but if I am changing to a em/lm combo on the turbo do I need an outlet pipe for a 64 or a 65.

You need the 64 pipe.

Craig replies: What year car are you working on? If it's a '65-6 you need a 65-6 pipe. The turbo hot side needs to have a donut style gasket and bevel to match the pipe.

It's a 64. I wasn't sure if changing the turbo changed what down pipe I needed. So I take it I need a 64 style.

I might have a new Clarks down pipe for sale. Have to look for it to make sure. Will check in a few days for it.

If your turbo's "hot side" is '64 style (donut gasket), you need a '64 exhaust pipe. If your turbo's "hot side is '62-3 style (flat gasket), you need a 62-3 exhaust pipe.
