1979 Merc 260 Crank Pulley Removal

[Ralph 123]

What's the proper way to remove the crank pulley (just the pulley - balancer is fine I think). Should I be able to remove the 3 bolts and slide the pulley off the crank and/or gently pry between the pulley and the balancer or do I need a puller of some sort?

The 3 bolts should be it Ralph. If it's been on a while it may be grouchy and require a little "assistance".

It is grouchy for sure.. How safe is it to pry between the balancer and the pulley?

Don't Pry Against the Balancer ,...............<br /><br />The Balancer is nothing more the a couple pc.s of steel, held together with a strip of Rubber,........<br /> Don't Pry Against the Balancer ...........<br /><br />You might try soaking it(The Pulley) good with your choice of penertrating oil,+ Tapping on it,........<br />1 trick is,.. Use a punch to reach the Flat Surface, right where the bolts go that you just took out,....... Several Good Swats, will usually free things up,...... It doesn't make a lot of sense,.. but driving it On, will help you get it Off...........<br />It'll cause the pulley to spring from it's mounting point.......... <br /><br /><br />BTW,........<br />It's about Time you went to Work on that Old Barge,......................... <br />I've had this 1 old interupt switch sitting on My desk for Months,..............<br /><br />I Guess you Don't Need It,..???... I never found a Mate for it............

There may be another bolt. some pullys use the crank nose bolt also.

Yup, that was it BTD. The nose bolt went through a washer and through the center of the pulley. I finally said, what the heck, cracked the bolt and the pulley came right off. <br /><br />The pulley was only put on the engine 3 years ago and was a retread from the original 1979 260s. It developed a wobble and I wanted to get it swapped out before it became a problem.

Hey Bondo,<br /><br />Yep I need it. Still got my info? Even if I just get the starboard engine shifting easily for now I'll be happy - it's got the power steering. I need to go check out those "retro" kits merc is selling to see if I can make them work...

Sorry Ralph, I assumed you had the crank bolt already out... should not have done that. My bad!<br />At least you have it off now.
