Water Pump Replaced

Justwondering · Jun 16, 2018

Today was a mighty successful day.
I got the following removed:

1. All 4 v-belts
2. Heater hose
3. Upper radiator hose
4. bypass hose
5. bracket under the a/c compressor
6. bracket off the alternator
7. pitcock valve
8. fan shroud
9. fan
10. fan clutch (fluid fan drive )
11. water pump
12. bracket loosened on the smog pump
13. bracket loosened on the power steering pump
14. thermostat
15. spacer for the brackets on the smog & power steering pump
16. Lower radiator hose
17. Some bracket I don't know what the heck it is for and only sorta know where it might go

I'll add a picture of the mystery bracket.
I don't think I need it, but if someone could post a parts page I'd appreciate it.

Cleaned out the pitcock valve so it would flow again. Added teflon and put it back in the radiator.

Cleaned all the water pump bolts. Half of them were extremely rusty on the shafts but not on the threads. Put lithium grease on the bolts to help them resist the rust.

Cleaned off the mating surface for the pump -- yuck. Most of the gasket was gone.

Compared the old pump to the new pump. Oh lordy lordy.
Old pump would turn by hand but it was a bit gravely when it rotated.
It also felt like it was rubbing metal on metal, as if it had no orings in it.

Made me feel like I made the right call last week by ordering these parts (water pump, fan clutch - heavy duty although it didn't seem any more heavy or durable than what came out, and a new radiator cap with the cute lever so it can easily burp.)

I've put the gasket on and the pump on and as many brackets as I could, but left the other half to do until tommorrow.

I'll resize the photos and add them in a few minutes.

But I'm concerned I don't know if I should put this last mystery part back on or not.

Nice work, take a break

Not sure what your cooling requirements are, but is this a 'like for like' pump replacement? My point being, you could always source and install the HD pump, or at the very least one that has a higher impeller count. This approach will help the pump move more water while the HD pump has a thicker pump shaft I believe.

awesome!

I just went for a like replacement.
I stared at the car today after I spent 2 hours working on the IH 1086 a/c and then followed it with 3 hours cleaning out half a storage container so I could move cardboard into it.

Then I sat looking at the car and kept thinking about AJ/Forms telling me to take a break.

So I left it undone, came home and grilled pork chops for Father's day dinner.

Now, I am continuing my contemplation by putzing on the computer. Leaving things undone!

Mystery bracket..

I think this was sitting horizontal across the two bottom bolts on the water pump. Guess I should have turned the picture 90 degrees.

The only shiny place was the two bolt holes, the cylinder was not shiny inside or out. As if it had a purpose that was not in use on my chrysler.

I did not put it back on.

Hand picked fresh blueberries from the two bushes we are growing in a bathtub in the garden. Can't keep them in good shape in our light soil. They love it there. Our first year with these two plants.

After I removed the pitcock valve I realized why it wasn't draining.

Some of the bug gunk I removed is on the tip of the box blade.

Old pump above, new pump below.

I was told that bracket is used at the factory for checking the timing, or rather to hold the tool that checks the timing or something like that.

WOW look at the size of those berries! Our biggest up here are about half the size of yours

80mirada · Jun 17, 2018

it is the magnetic timing pickup holder for the ELB diagnostic tester, it was use to time the engine at the factory. Your replacement pump is the heavy duty/large bearing pump, all A/C, and heavy duty cooling cars should have them.

Justwondering · Jun 18, 2018

yea!
I go there (Oreillys) so often and generally am wandering around in the weeds, that they have learned to suggest the better grade of parts or I will be back to return it.

So it sounds like as long as I don't plan on learning to time the engine, that little bracket is not going back on and should not adversely affect anything.

I'm hoping to have everything back together late this afternoon. Fingers crossed.

Great point 80mirada...if I can add something to the above it is the following: easy way to distinguish the standard from heavy duty pumps is by looking at the housing where cooling fan/clutch attach...if the housing has the shape like what you show it's the HD, if the housing has 'pipe' like casting, that is the standard pump...LOL, heck, I wish I had a picture handy to show this...my description above is not very good...I tried....

You would be hard pressed to find a usable magnetic timing tool nowadays. I do have a buddy that has the original Mopar ignition testers, including magnetic timing probes, in near perfect condition. We still used a traditional timing light to recheck the timing.

There are actually three different style water pump castings for LA style (small block) mopar V8s, now. I will see if I have pictures of the other two.

Aspen500 · Jun 18, 2018

A good many of those timing brackets "vanished" back in the day. Usually when the water pump was changed or the front of the engine was opened up, the magnetic timing deal never went back on. No reason for it. Timing is done with a regular light and the markings on the timing chain cover.

M_Body_Coupe --
If it looks fluted like a bundt pan then its heavy duty,
if it looks smooth like pvc pipe then it is NOT heavy duty.

Hmmmmm
Bundt pan = bundt cake .... and I just got a dozen fresh eggs.....

As of Monday, everything is back together.
Took me forever to get the belts tight enough so I could try starting the car.
When I would turn the A/C on to max, I had a rattle so I think the alternator belts need to be tightened just a bit more.

Only had 2 parts left over and lost 1 nut.

Not bad for my first time on this. Today the car goes to the mechanic and he's going to backstop my work and we will discuss belts at that time.

More news later.

Drum roll please ......
Mechanic says I did the fan, fan clutch, water pump, hoses, belts -- everything just right!

HOWEVER,

When I pushed the button for MAX A/C it sounded like a jackhammer ...

Ordered an a/c compressor, drier, expansion valve and it gets replaced tomorrow assuming I can get access to a vacuum pump.

Nice Job JW. Nice picture story as well. The mind always goes to food.
Speaking of blueberries, How do you grow them so well. I have tried them before, and followed all soil recommendations and have not had them survive. Do you have a picture of the plants ?

Justwondering · Jun 28, 2018

I'll take pictures tomorrow of the blueberry plants.

We are growing them in containers. Pure peat most until the top 5 inches or so and that is potting soil. Water from the pond or the sky if it rains.

Not growing them in the ground here because our soil is super sandy and very light (not much humus in it).

My containers are left over from when I ran a fiberglass plant. These are the masters we made bathtub molds from. Although, I've also had friends who just screwed together word to form (essentially) a box with only 4 sides -- no top or bottom.
Another friend stacked tires about 4 high and grew them above ground as well.

The height makes it very easy on your back when you are picking berries.

I have the blueberry plant pictures, but my phone was dropped over the celebration this weekend and now I need to have the glass replaced. Ugh.
I'll back it up and get it to the doctor.

I did take the car to the mechanic and all 3 said 'great job' and I got to see what a break-over bar looks like. I had no idea there was such a thing.

The only downside was when I pushed that button for the a/c it sounded like a jackhammer under the hood.

Yep.
Gotta replace the compressor.

I just got all the parts (compressor, expansion valve, drier and extra gaskets, pag oil, and refrigerant) so I can do that tomorrow when its cooler (lol -- not 104 but 98).

Bought myself a set of gauges but still looking for a vacuum pump. Seeing hows the a/c is out on the tractor and at this time of year getting a loaner from the stores in town is nearly impossible, I figured I'd spring for a vacuum pump.

Just think of all the other science experiments I can now try! This is a very educational purchase ... not impractical at all.

lol

JW
(and yes, my first experiment will involve marshmellows)

I pirated a compressor from an old refrigerator and glued some parts store fittings on the lines
