I’m not sure I’m willing to give anyone trying to use a conventional puller vs the correct tool that much credit, especially once torches and hammers get involved...

Ebay is a good source for service manuals and specialty tools. The manual lists the merc part number for the tool for each task that requires one and you can usually find the tool itself on ebay too. Any V6 manual will give the basic mechanical info as they are all very similar mechanically!

If you can’t find (or afford/justify cost for one time use) a post here will probably find a near by member that can help.

Myself no substitute for the correct tool. OMG and others backing the nut to the top of the threads is a must.

The tool is cheap compared to a new flywheel. Not to mention if you pull metal on the crank taper...

Had one in here a few years back and I seen the crank was not showing any thread past the nylock. Told him his flywheel was about to come off but he assured me it was tight. They had already destroyed the end of the crank and had cut off the ruined part leaving the crank too short for it to engage. I refused to work on it till he could afford to change the crank. Don't think most have any idea how dangerous that is.

A loose flywheel buzzing arond at a couple thousand rpm’s? Yep, not a good situation!

Backing the nut off will save the crank, (SOMETIMES), but so much for the flywheel and magnets, if it's on tight it will ruin it....if it's on loose it may already have ruined the splines.....BOTH crank and FW!!!

Does the Acronym, RTFM ring a bell? I sure hope he hasn't done a BUNCH of damage to $ome very expen$ive part$.

Read The F****** Manual

Saves so many headaches. Also ask questions BEFORE taking a hammer to parts...

The manual wasn't written to be ignored...............................................

Never had a Merc flywheel that didn't pop right off with the proper tool.

Mine looks like it's been in a war. Bolt's bent and there is a small chunk out of the side of the crank protector. It's been used and it still works well.

The latest version of Mercs puller is pretty slick.
