Motor is all apart, heads and all. Fixing a LIM and head gasket problem. While I'm here, I want to change the O-ring on the oil pump drive. I took out the 15mm bolt on the retainer, but the drive won't pull straight up like the Chiltons manual says it should. It spins in circles very freely, but there is ZERO up and down play. I got a pair of vice grips clamped on it real hard, and even with those pulling straight up I get nothing.

Am I missing something? Is there atrick or special tool needed for this???

It's a 3100 '98 Monte Carlo.

Thanks!

Never mind, I got it. If anybody else ever runs into this problem, just give it a few light taps with a metal hammer and it will loosen up a bit. Keep pulling upwards with some vice grips, rotate it, more taps with the hammer, rotate, pull up, and keep repeating until it "breaks loose" and slides straight up.

 

Is the darn thing press fitted?!?!?!

 

No, it's not press fitted. I think it was hard to pull because the O-ring was hardened. When I tried to pull it off the drive shaft, it just broke apart it was so hard a brittle.

 

Ok, that makes sense. I couldn't see it being press fitted but a new "engineering" design wouldn't suprise me.

 

Lol.. New enginnering.. 2007 model hammer? lol
