Title: crank sprocket
Post by: somolovitch3 on November 20, 2007, 07:13:24 pm

Would not believe the search results................with no hits!

How does one remove the crank sprocket? :oops:

Bentley says "remove the crankshaft sprocket.."

With what/how? :twisted:

TIA

Oh man. That's not a fun one to do. Best is to loosen the bolt while the engine is still in the car. You may have to take off the oil pan and wedge a 2x4 between a crank lobe and the floor. Sometimes you can loosen it by having someone press the brake pedal HARD and have the tranny in fifth. Often though, the wheels will rotate anyway and you'll have to do the wood method.

I'd like to hear other ways because I don't really like either method.

i removed mine with a bar wedged on the flywheel bolts.  worked good.  will be using new ones anyway.  has anyone ever tried an impact on them?  i can't remember if we tried using the impact or not... either way it came off with a nice long bar.

If the timing belt is still on: impact wrench.

Okay.................................GOTTS THE DAMN BOLT OFF!!!!!!!!!!!!!!!!!!!!!!!!



Now, how does I get the sprocket off the end of the crank?



BTW, 1/2" impact gun at 100 psi works just fine to remove bolt...........

Tighting it up on rebuild might be a -itch.

I like the look of that angle iron bar......big ass guy hanging on to it while I torque the bolt down....then engine goes back in truck.

If you make the long-bar pulley holder tool and bolt it to the pulley, once you remove the bolt the holder tool will help remove the pulley from the shaft.  Otherwise, a tap with a soft hammer should loosen it.  

Here's my home-made tool for removing the bolt while the engine is in the car:

And here's the pulley still attached to the tool.  In my case, the tool/pulley assembly practically fell off the shaft.

Sorry to be so dumb, but what size/type socket is required for this bolt?

I believe there are a few different bolts. I think mine was 19mm.

My '94 TD has a 19-mm bolt head.  But I have the "updated" TDI bolt, as I understand it.  I think someone told me the bolt with the raised center is a TDI bolt.

Yup, it's 19mm.... just need a 12-point socket rather than the more common 6-point socket... more expensive kits will have 'em.

I tried to cheat last night and use an old 3/8 drive 12-point 19mm socket on the breaker bar with a 1/2 to 3/8 adapter... twisted the adapter right off... luckily right at the end of the "extra half-turn" step.... but I'm off to invest in a proper 1/2" drive 19mm 12-point.

If you can, get an impact one.  It'll hold up no problems.

Once the bolt (Play nice now children :twisted: ) is out, I have found that my steering wheel puller worked like a charm (just lucky I guess  :roll: )


I DO appreciate all that replied,................ if it had been the damn bolt, I would have said so.......................

I also have answered what I thought was the questioned asked, not just the question that WAS asked. :oops:  :oops:  :oops:

Thank you one and all for ALL the anserws.!!!!

Now, my next question is...............................................................

You can get a 19mm 1/2" socket a Lowe's for $4. Lifetime Warranty.
Don't forget to discard and replace bolt.
