Removing Pulleys on Merc 3.0L

[SteveRay]

I have noticed some pitting on some of my pulleys and it was suggested to paint them. I was wondering if there are specialty tools need to remove them. I have a brand new alternator on there so that one is good. I think there are two on the motor and one on the power steering pump. I am most concerned about the ones on the motor

I never can get the paint to stay on. I sand them smooth with emory paper in the beginning of the season. Rust will stay off with regular use. I'll probably be keel-hauled for saying this, but I do 'em with the engine running [carefully]with a pair of vice grips to hold it. Never get your fingers anywhere near the belts or the pulley grooves. It goes real quick.

For the power steering, you'll need a special puller-installer for the pump pulley, available at most quality auto shops. $60-90? THERE IS NO SUSBSTITUTE!

Cleaning rusted pulleys -<br />If you have access to a angle grinder - buy a 4" narrow wire wheel -<br />not at the hardware store - a good $15 coarse wheel - that will fit down into <br />pulleys - remove belts - <br /><br />With good eye and face protection - brush them - pulleys will rotate with<br />grinder. Give them hell. - Spray with a hard paint, 3 or 4 coats, over 2-3<br />days. This should fill rust pits. <br />Degreease pulleys with denatured alcohol before<br />painting. <br /><br />All pulleys will come off when bolts are removed - except power steering. <br /><br />At Harbor Freight or Northern Tools you can buy a power steering pulley<br />removal - install tool for $20. Not the best- but will work 30 times.<br /><br />Or at many auto parts stores - they have a loaner for free. A returnable<br />$20 deposit, with instructions. An air impact wrench helps. <br /><br />Belts do not pull from bottom of pulley - but from the side of the belt -<br />At auto parts store do not buy the cheap belt - buy their best.<br /><br />Paint does not stick to oily metal.<br />This will work - the easy way.

Thanks for all the help guys. I got at em last night and saw what evryone was talking about.<br />The problem was that the water pmp pulley wont come off because of the front motor mount and the botom(crankshaft pulley?) looks impossible to remove.???? I am borrowing a power steering pulley remover from a friend at work, so that solves that.<br />I cleaned the waterpump pulley real good and the crankshaft one ok. Did this with a hard wire brush and scoth brite pad. Cleaned everything and installed a new belt and I will check to see if it still eats it up. Thanks again
