Which seawater pump would you recommend?

davidbrooks

MATCO set is $85, i paid $15 for a no name and no quality set. I figure i got about $1 worth of use out of it.  Couldnt agree with you more Al.

@pistole which one? The one from Advance Auto ot the POS one i got from Amazon.

both , if possible. At least the guys here have an idea about how to deal with these pumps.

The loaner i got was from Advance Auto.  It was https://shop.advanceautoparts.com/p/powerbuilt-tools-power-steering-alternator-pulley-puller-kit-14-piece-loaner-tool-648605/9150040-P?searchTerm=pulley+puller.  Basically you buy it, use it, then return it for a full refund.  I also used a 1/2 ratchet and breaker bar with socket for the end.  The breaker bar is about 14" long.  To hold the nut i have a long craftsman box end wrench...again about 14 in long.  Both of these gave me the leverage i needed to pull it off without air tools. 

Now the crappy one i thought i would try was  https://www.amazon.com/gp/product/B073ZFF44N/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1.  Do not get that.  It looks like what you want but is horrible quality.  As Al said.  Google MATCO Pulley puller and you will find a kit for about $85. I like having the tools. So i will likely buy it. I normally work in a new tool with just about every project i take on.

Me too. But now I need a bigger tool box.

And when all else fails....add in a 2ft section of steel pipe aka the cheater bar.

Is this the Matco kit?

@Alswagg - would you mind checking the model number on your Matco puller? 

I got the Matco MST93 and the Powerbilt 648605 loaner from Advance Auto, but neither one fits.  The pulley hub is 2.1" diameter, and the collars on the pullers are only about 1.6" diameter.

Al is on vacation for a few weeks.

I think there might be two versions of the Hardin pump.  One has the pulley attached to the shaft.  The other has a pulley hub attached to the shaft, and the pulley is bolted to the hub. I have the hub version, and the Matco puller won't fit it.

reneechris14

Yes that is different. Is that your pulley in the back ground. That is after market.

Dream_Inn

Yes, I have the pulley on shaft version.  Did you order yours with the pulley?

LaRea

The inner seal failed and leaked water into the bearings.  I have a rebuild kit, but the hub has to come off first.  Then I can remove the outer seal, and remove the shaft for the rebuild.

I now have three pumps:  two on the boat, one in my shop for rebuild.  All three have the same hub.  The pulley attaches to the hub with four bolts.  The pulley covers the hub completely.  

LaRea

I bought them all direct from Hardin, with the pulleys attached.  Here's the photo on their web site.  (They now deliver them with a black finish pulley.)

Dream_Inn

Yes, the black finish one is what I've seen (It's what Glenn has bought).  I'll have to make a note on this, because the day I have to replace my other one with a Hardin (It's only 2 years old, so hopefully a while), I'll replace it without the pulley again so I have them both the same.

LaRea

I've tried 2-jaw pullers, 3-jaw pullers, harmonic balancer pullers ... fail, fail and fail.  If you pull on the edge of the hub, the hub bends, so it squeezes the shaft even tighter.  

Gotta find something like the Matco, but big enough to fit around the top of the hub.  

Dream_Inn

Have you called someone at Hardin to see what they'd recommend? 

LaRea

Emailed, no response - need to find a chance to call them during work hours.

LaRea

Hardin recommends using a harmonic balancer puller to remove the hub.  I guess they mean a GOOD one -- not the $20 POS that I have, but one like this:

https://www.amazon.com/OTC-4531-Harmonic-Balancer-Installer/dp/B000F5LIW4

  

So, new problem.  This type of puller has an adapter that screws into the center of the hub for reinstalling the hub.  I need a 3/8" adapter, and nobody makes one smaller than 1/2".  

reneechris14

I think you want all 4 bolts to pull also. The hub is aluminum and you said it bends a little.

My crumby harbor freight pulley puller is stuck/seized on a pulley where I cannot remove it. Looks like I'll be ordering a matco puller kit soon like I should have. 

LaRea

Not likely - they all have 2-bolt and 3-bolt patterns, but I've never seen 4-bolt.  The guy at Hardin suggested Snap-On, but I found nothing there.
