Comp turbo failure less than a mile

jchammond

I've seen the pressed/drive in zerk fittings on a dump truck body,,,but couldn't imagine it on an expensive Turbo.
Hold on......This must be an "April-Fool's Joke"

I will be on COMP right away to get this figured out. I believe these are pressed in, so one can't simply pull hard when disconnecting the grease hose from the zerk. Common practice is to push the grease gun (hose end) fitting to one side until it pops off, instead of a straight pull.

I understand that this may have fallen out at some point during operation, which is not right.

I will make a suggestion to have these threaded in as well.

Thank you Sasha for the fast reply, I am curious to hear Comp's response on the cause and what they would like to do. One of my concerns with the grease fitting falling out is that the grease when heated in the turbo liquefies and is supposed to cool/lubricate the turbo from what has been described to me about these oil-less turbo's. Without the fitting there I can only assume that the grease has now leaked out basically running the turbo somewhat dry or just not efficiently lubricated/cooled by the grease anymore possibly causing this turbo to prematurely to wear.

Rapid response from "BP",,,that's awesome customer service!

From COMP:

He can reinstall the fitting we can send one out tomorrow very easy install . Or if the customer doesn't feel confident we will pay for shipping both ways .

The stem is indwwd threaded in to the bearing housing.

This is what makes COMP the company of choice for me. It is Easter Sunday, and issues are getting resolved, and customers are being taken care of.

The next time OP greases the turbo. Only do 3 pumps or less to grease. Don't try and force the grease in. When the handle starts to get hard to pump, STOP! If You try and force it. You are now using hydraulics, and you WILL do damage. You can force the zerk fitting out, and damage the bearing seals.

Just to clarify for the thread so this doesn't become a "installation error or greasing error or user error thing " I have not even opened the grease, grease gun or grease gun hose. I have not greased this turbo yet and the zerk fitting just fell out at some point in time just driving the car.

I'm just giving you a heads up on greasing.

A press fit zerk fitting is not screwed into place. As there are no threads. So there are no torque specs. You have to either press them in, or beat them in. I have used a socket, extension and a hammer to tap them in place.

Problem you may have is a slightly bigger hole then what is called for. Or the zerk was undersized. One is the reason why the zerk fell out.

The zerk is threaded into the stem, and the stem is threaded into the center section. Nothing is pressed in.

OP, I will check with COMP on the torque spec, and other things mentioned.

I can certainly put the new one in myself, but I still would be a little concerned about the overall health of the turbo since its had 700 plus miles put on it with no idea when it fell off. Was it not torqued down properly in the first place? what is the torque spec they recommend?, are these prone to falling out and should be checked every trip? Is there a high temp loctite that should be used? Should the turbo be sent to Comp for inspection?

I just want to make sure every little thing gets smoothed out with the Comp turbo's. So far its been great but I can only imagine that if this were to fall out and someone not catch it in time that it could severely damage the turbo and possibly someones engine when it lets go. I would be curious on Comp's response on how bad not having this fitting in the turbo would be since the grease leaks out without it.

Thanks for checking in with them Sasha

Well, as long as we're asking. What about a Borg Warner efr?

Not to bring this thread from the dead but what ever came of this. Did Comp send you a zerk fitting? What size thread on the zerk? Was the turbo hurt? Anything?

Boosted Performance

This was taken care of by COMP. I got your email, and have replied as well.

As Sasha mentioned, Comp sent out a new zerk fitting....Im unsure on thread size and pitch unfortunately. To the best of my knowledge the turbo seems to be fine.

Sasha and Comp turbo have been great to work with and the car has been running amazingly well.

Currently figuring out a fully built block and bigger/better fueling system for big numbers hopefully.
