Halp the waterpump is stuck. I tried to pry it off and hammered it a bit with big *** screwdriver. But I want to be gentle as not to break something like the omp lines. Tips on how to get this rusted biotch off?

spray some wd-40 into the bolt holes then hit it witha rubber mallett like it owes you money. hit the snout of the water pump, under the pulley. it's away from the omp lines enough that if you're a good shot you wont break your already brittle and in need o replacement OMP lines. it'll submit.

Vashner

Thanks i'll try it. There's a rubber mallet around here somewhere.

Make sure you didn't miss a bolt or something before you break out the big hammer...

Vashner

Checked that. I try to use the service manual as much as possible. Sometimes it pisses me off and lacks detail. I need to order the other 3rd party books.

hey vashner your just going to have to remove the omp and make some more room...tap or hammer the back of the water pump with a rubber mallet and go to town on it...Even my none rusty waterpumps that use silicone are a bitch to take off from time to time...And being that that the studs are rusty as well does not help the whole process so it makes everything just a little harder

Everyone is wrong. You have to remove the main drive pulley. Four 10mm bolts. Then, if you want to, pull off the MOP lines from the MOP itself or unhook them from the carb, pry open the sheet metal clip and rotate them down out of the way. The waterpump will slide right off the four studs.

never had to remove the main drive pulley to get the water pump off.

The pulley or the hub? I've found it's necessary to remove the pulley. Plus this guy's setup appears to have an accessory pulley. His pulley must come off if he is to make any progress.

you sure you didn't miss the bolt right under the pulley below the weep hole its hard to see and even harder to get to. and what part of the pump are you prying on your not trying to take the whole unit out are you. just take off the front part. leave the housing attached otherwise you will have to take the studs out if you want to leave the main drive pulley on. just my 2 cents though I've only had to mess with this thing 4 times in the past 2 weeks

bugman1973

if he has the same accessory pulley i have he wont be able to just take the 4 bolts off of it the accessory portion will be attached to the big bolt in the e-shaft. and the involves oil coming out of the engine if you do that

bugman1973

also i stuck a chisel in there and hit it with a mallet

Vashner

Yes I got that lower nut with an open wrench.

So I should drain the oil first? The AC pulley is for the Sanden SD508 based system. Which I don't plan on hooking back up anytime soon.

Well i'll just put the clutch in just to be sure i'll chop a tree branch or something.

If the aluminum pump housing is corroded onto the steel mounting bolts and studs, you can try "Liquid wrench" which has a mild acid solution. That may help, if it sits for awhile.

For this kind of hammering and bashing I like to use a bronze mallet because it has a nice soft-blow hammer effect. Or you can even use a real soft-blow hammer which has loose leadshot inside the head to provide good follow-thru on the blow.

But usually the prognosis is not good with steel-aluminum corrosion.

Use anti-seize when re-assembling things. You can get a lifetime supply for about $4.

Oh **** i didn't even see he still had the main drive pulley on...**** my bad ...take off the four bolt on the main drive pulley, take of the larger pulley...while still leaving the other pulley that is for the alternator on the e-shaft without miss alignining the holes, put the 4 bolts back on and the water pump will come off a whole **** load easier...

**** man my bad i didn't see the larger main pulley was still there...

Vashner

It's cool I have not started (past the pic) yet. Taking my time since it's not my main ride just a restoration project. Thx for the excellent advice will post a pic when it's done.

Vashner

Got the new pump on but...

Ah "Beep".... One of the thermostat housing bolts broke off!!!

...


So I guess I need to get a salvage housing? .. f.... k..

Sigh.. I wonder if there is a way to just use one bolt and put something like a clamp on and or something like JB Weld. I just wanted to put a new thermostat
in since I had everything apart. If I can put a new one in and just rig up something. Opinions requested. I don't think I can ez tap that bolt out. It broke with maybe 30-50lbs torque.

mikewoodkozar

pull off the whole water pump housing and have someone drill out that old bolt if you cant

bliffle

That's normal.

You need the 8mm "Heli-coil" kit for drilling out the bolt remnant and screwing in a heli-coil, which will screw into the new enlarges threads and provide new threads for the bolt (which you can get in a blister pack at the autostore and even some hardware stores). Around here it's $50, but will do many such breakages. I just did one last month.

Too bad you're not closer or I could come over and do it in a trice.

This bolt breaks on almost any car that I know of. It serves to remind you to use anti-seize on every bolt or nut you screw into your car! Only $4 for a lifetime supply! Available in handy packets at the autostore checkout counter for a buck!

But first, just for the hell of it, try drilling a straight hole down through the bolt remnant and try removing it with a right-size EZout from the autostore or Ace hardware or truValue or even HD. Maybe it'll work for you, and it's only about $3.

Oh, I made a specially modified C-clamp many years ago for just such purpose, but it doesn't work well and looks awful, so I only used it once.

Vashner

How much hassle is it to remove the WP houseing? I can get one salvage for $50 bucks.

I'll try the ez out tomorrow before ordering the part. I can hit it with some more PB blaster now
that the thermostat house is out of the way.

Yea this looks like the factory thermostat so the bolts been in there since 84. lol.. damn Rust never sleeps.

Damn that sucks bro...let us know the outcome

mikewoodkozar

It is VERY easy to remove the whole assembly, just remove the rest of the bolts that are still on the assembly and remove them. Dont forget to keep an eye out for the paper thin washer that is in between the water pump housing an the block. If you loose it, it will leak. Might as well have the water pump assembly bead blasted when its out and then paint it so it resists rust a lil better next time. That is what i did.

mikewoodkozar

Mine was as bad or worse than yours and here is how it turned out

Vashner

Yea I think your FB is one of the nicest ones I have seen.

It looks like the broken section is only 3-4 threads deep so I hit it with the PB.

That PB **** is a miracle juice.
