TR6 Thrust Washer Check & Installation
by James Davis, firstname.lastname@example.org
TR6 thrust washers tend to wear themselves out in short order, and sometimes require replacement even after as few as 50,000 miles. A common problem with them is that they can easily be installed backwards, in which case they wear out VERY fast, even in as little as a few thousand miles.
This article describes first how to quickly check to see if your thrust washers may need replacement, and then how to make sure they are installed the right way ’round.
Checking the Thrust Washers
Checking the condition of the thrust washers is quite straightforward, and doesn’t even require opening up anything on the engine! This is a good check to repeat every few thousand miles, as letting worn thrust washers continue to wear away can require a different crankshaft and block if the condition is severe enough.
To check, simply push the crankshaft pulley rearward as hard as you can, then have an assistant sit in the car. Now, use your hand to span the space between the crank pulley and the front of the engine, and inform your assistant to lightly step on the clutch pedal. You’ll feel the crank pulley move forward slightly, and this will reveal the condition of the thrust washers.
The allowable axial play for the crankshaft is .007-.013 If the distance seems greater than say, the thickness of your fingernail, you should bargain for a lower price, knowing that you’ll have to be into the lower end of the motor soon. If the distance
