Stuck Meziere WP

[Svashtar]

I worked around the big pulley because I don't see a way to remove it. I got the top three bolts out pretty easy and the fourth (the worst for access on the bottom) took more work but I finally got it out.

Trouble is, it won't budge. Whacking it with a mallet hasn't helped. The pump is bad anyway so I guess I could use a puller on it, but that will probably tear it up.

Thanks for any ideas.

BTW, now I know why Meziere supplies short stainless allen head bolts with the pump. An allen wrench gives you way more clearance around the pulley.

But the mechanic who installed it at the time chose to use regular bolts instead. Easier for him I guess, but harder to get clearance to get them off.

He must have slathered a ton of gasket maker around the back to make it this hard to remove...

Puller is not going to help you there. Couple pry bars and wood shims as to not marr the aluminum, you will have to work it off they can be a pain

Ok, that's a good idea; wood block behind the pulley and a pry bar leveraging off the block. I'll give it a try, and thanks for the suggestion.

I removed an OEM WP from another Ford last year and it practically fell into my hands when the last bolt came out, so this was a surprise.

Thanks again.

Took over two hours but I finally got it out: whacked the top of a 2x4 placed on the pulley with a hand sledge to break it loose, then banged all around the pulley for a couple of hours while providing back tension with a (padded) pry bar to walk it out a fraction at a time. It was incredibly tight. The pulley is dinged up, but the pump was dead anyway so I'll live.

My main concern was that I would hurt the block somehow by working the pump loose, but it looks OK in there.

Q: should I use anti-seize on the back of the new pump?

Q2: in feeling for the bottom bolt I accidentally loosened one of the 13mm bolts on the timing cover at the six o'clock position under the WP. I tightened it back up, but does that need torqued?

Thanks!

I wouldn't worry about tightening that bolt, use your head..make it tight just don't go at it hard..it's not a head bolt.

Do not use anything when installing new pump other some fresh coolant on the new o-ring.

Perfect, thanks Larry. I couldn't see anything on the old pump either, must have just been the aluminum block hanging onto it. Appreciate the info.

Did the Meziere installer use Permatex or another sealer on it??:confused:

I would used a little Silicone Grease on the O-Ring when you install your new pump.......just helps it slide into the block!!:beer:

Thanks for the tip. I don't think he used Permatex, but there was some kind of sludge left around the seal area, so something was in there. The bottom line is the tolerances on the Meziere were very very fine, and there was just no movement on it _at all_. I'm convinced it wouldn't have leaked (for a while) if I could have run it without the mounting bolts.

I'm torn between doing what I had to do to get it out, and the stupidity of beating on it 360, especially from TDC, to "shake it loose," when I should have been pulling more while giving it sharp raps.

What finally worked was _consistently_ putting hard pressure forward on the pump with a padded pry bar to protect the block, which did nothing on its own, (even with two bars), while also rapping hard on the pulley / housing 180 degrees opposite, then switching positions and repeating, over and over, which gave me a 32nd of an inch at a time.

The plan was to send the broken EWP back to Meziere for repair of the bearing, which would have run me about $175-$200 total, then resell it for say $300, but with the total hours I have on the pulley, plus the stress I just caused it, I'd be ripping someone off. Bearing failure or not, and I think Meziere has failed me twice now on longevity, credit due to them as the pump is built like a tank, but I don't want to take the chance.

At this point I'm just upset about the stress I put on the block by all the banging on the pump; I try to baby the motor, but it looks OK.

Thanks again for the tip on the silicone lube.
