Damm, mine thrust are f.cked
Turbo Mini Forums

Hi,

mine engine stopped when i pressed the clutch
And after reading some info on this site i suspected mine thrusts.
And now i know for sure that they are the problem.

I feel there is some material still on the crank so now i come to you. I read that if youre crank is not perfectly smooth (feeling with youre fingertips) get it to a workshop to get it a regrind. But how does this work? Do i give them mine crank to get it regrinded or must i give them the complete block?

I'm also thinking of the possibility to get some wet sandingpaper and try to get the crank clean.

Any info would be appreciated
:)

there is nothing wrong with a A-series that a turbo can't fix.

Take the crank out of the engine. You will know if your thrusts are damaged, they will look like this



You will need to get the thrust face ground and fit oversized thrusts

It really depends on how bad the damage is. Maybe you could post a pic of the damage ?

"So wat we gonna do tonight Brain?"
"Same thing we do evernight Pinky!"
"Try to take over the world!"

Bah, those are like new...

I saw worse than that recently. They had dug a 1/8" groove into the cap.

I believe that wolfie couldn't find his when he stripped his down.

If something is worth doing, it's worth doing half of.

This is what i found when i went searching for my little problem

The rests of the trusts are on the crank and in the sump of the gearbox

wow

Yep, theres your problem :)

LMFAO, Wet 'N' Dry

sorry!

The crank will deffo need to go to the machine shop. Block possibly. I say the block might need to go to the machine shop, as you will have to check the roundness of the center bearing housing (block/ cap) as any excessive heat from the thrusts can distort the center bearing housing. Also, if the thrusts have spun, the facing on the block/ cap needs checking that it is perpendicular to the bearing housing/ crank journal.

Secondly, you need to find out why this happend in the first place. What clutch do you use and has it been assembled with the correct lug hights?

ok, block will go to a machine shop.
And since everything is open i will make some more mods.
Like Carls mod on the thrusts

The problem is most likely, old thrust with grey clutchcover. I've red some more people had problems with it.

ouch!

what does the back of the thrusts look like, can you see any copper material left?

What was the crankshaft endfloat when built?

Damn,

those thrusts look pretty fooked.

Oilgrooves must be facing outwards, my endfloat is what Haynes quotes.

What is the optimal endfloat when going turbo?

(sorry for hyjacking the thread)

If something is worth doing, it's worth doing half of.

The other side has some copper left but the most of it has gone.

I can not remember the exact endfloat i got. But i do remember it was right between the min en max the Haynes said. I was, at that moment pretty pleased because i did not have any other thrust at hand when we put the engine together.

the back does not have any copper on it to start with. I assume the thrusts have spun especially if you found one half in the sump?

0.005" thrust is fine

Van's were quite loose IIRC around 5thou
