Mopar Water Pump Housing - Machining .240" off Thickness

[@kevinhillgrenjr2248]

Means nothing to anyone outside the automotive world but that is not a water pump, it is a water pump housing. As always a great video, your care to detail and precision is inspiring.

[@FFGOMER17]

Aww man, it was like watching a car wreck and not being able to stop it. I thought the flange was going to interfere while you were setting it up and then after your initial .025 cut I thought I saw a shiny spot. I was yelling at the tv “Adam, look at that flange!” I’m glad you noticed it before any serious damage was done. Great video, keep them coming!

👍Well spotted. I didn’t see it until it happened.

I worked on the shop floor, making parts for GM, 1970-1974. _Every_ Quality Control Inspection measurement was 10 thousandths. GM was machining more accurately than Chrysler in those days. We hourly workers at Oldsmobile took extrema pride in the fact that the Rocket Engine was machined to _greater_ accuracy than any other production engine in those model years. This new replacement part is machined to an accuracy that would have been thought absurd in 1972. I am _certain_ of this. Some insane owners had their engines "speced" in those days. That meant a machine shop tore down the new engine and machined all the parts to 1 thousandth; that is to the actual engineering specifications that were unobtainable when making 450,000 Cutlasses per year. The cost I am not sure about, but if memory serves, a Cutlass cost $2,500, and "specing" the engine cost $5,000.

Always awesome when you let Abom loose on an engine block, because of this being such a good lesson in metal working!

[@WayneGreathouse-h2y]

The flange was the only thing that I was concerned about. I had a 1978dodge B300 motorhomes and my only issue with it was the modern gas eating the plastic and the glue out of the bottom of the carburetor.. Wonderful job as always, I really like your work ethic on all of your work.

All's well that ends well. Turned out good.

[@nwg1972]

Beautiful machining job. As others have said, the customer is always right!. I think the custome may struggle to fit this watertight - look at the traces of the previous gasket on the old (red) housing at 50m 50s - look at the shape of the pipe in the upper left on the trimmed back (black) housing. Would be interested to hear how it turns out for them.

[@whitt2274]

I think that your trial of split screen and different angles was successful. This technique should add a noticeable increase in visual interest.

[@glopesfabio]

Great job! But I think there will be a leak problem with the gasket if the customer uses the original ones! With the housings side to side you can see the mark of the old gasket!

[@afnDavid]

Adam stuff !!

[@waynespyker5731]

The initial clearance check out missed a hand rotation at the finished minor diameter. Usually your tool can't get to that circular plane but with the underside valley would permit the set up check. Finding the flange interference if having enough lathe, pull the 3 jaw for a 4 jaw or face mill.

[@danielczoller3395]

I have same JBL!

[@joejoesmojo32]

My first thought was mill/face cutter. Cant understand why you wanted to use the lathe but i thought it was a cool idea.

[@WelpNopeYep]

Lathe probably takes 1/4th the time in setup and cutting. But he didnt properly think it through chasing the efficiency and caused it to take even longer. He knows what he did, anyone who works on anything has made the same mistake 1000 times.

[@bertblankenstein3738]

I'm not a machinist. I have to agree, the mill seemed like the way to go right from the beginning. No awkward piece spinning around, no questions about clearances. Just use some parallels to get the workpiece lifted and level and away you go.

[@truckguy6666]

The age old problem: should I spin the part or the cutter?

[@geckoproductions4128]

Just curious, why lathe instead of face mill? Thanks, enjoyed the video

[@silasmarner7586]

You're the 116th person to ask the same question , doink.

[@thor4038]

that's great and all but how would you charge for a project like that i would assume something like that would cost $ 150 for a face job ? how would you charge a costumer for a face job similar to this ?

[@marshalllarson8970]

I didn't even think of using the lathe. I thought you would go directly to the mill.

[@jimfiles3307]

I wonder if making a new pulley is possible. This would allow for a replacement off the shelf water pump to be installed without having to machine it too. It seems to me that there should be other mounting options that don’t require the water pump to be moved forward.

[@scrappy7571]

The water pump bolts to this housing, so any pump will now fit properly.

[@jimfiles3307]

After looking at this video I realized that the water pump will be mounted into this housing, therefore there will not be any problems with replacing the water pump in the future. I do wonder if there will be potential coolant leaks between this modification. If the adapter is machined to accept O-rings, then any minute discrepancies will not be a problem.

[@scrappy7571]

@@jimfiles3307 It's a 1/4 mile drag race car application. these things are torn down more often than the average grocery getter. Should not be a concern.

[@kenhawkins1033]

This kind of stuff always made me squirm. You want to hold the job securely, but you don't want to distort the workpiece. The easiest way to have something go haywire is to have the workpeice owner watch you work...

[@levitated-pit]

Hello Adam. Brit guy here! i am wondering what the US safety laws are like compared the UK? at my work we have an old Czechoslovak lathe and other machines in good condition but we are not allowed to use them because for example the lead screw is not shrouded! which seems a bit crazy as we are all old timers with lots of machining experience. the machines just sit there gathering dust and debris.

[@_Otaku-kt8be]

Give them away to a hobbyist or youtube creator in your area that would use them and needs them. You can always sell them too.

[@garybrenner6236]

Over here in the Colonies we don't use those guards.

[@lawrenceveinotte]

Nice job maching, somewhere something else has to be off on the engine to make the water pump pulley a quarter inch out.

[@scrappy7571]

They are adding a quarter inch thick plate between the housing and block. Known as an engine plate, it makes a solid engine mount for racing applications.

[@truckguy6666]

he said theres a motor plate which is a fance way instead of using motor mounts. 1/4 inch thick

[@tates11]

The finished size should be 0.250" less which is 3.347 - 0.250 = 3.097" not 3.087".

If can be done in a lathe, it is done in a lathe. If not, resort to other options 😅

There may indeed have been a slight variance in that pump to engine block mating surface once chucked in the lathe, but there’s not a soul in the world who would trust a manufacturer’s tolerance over an Abom tolerance!

[@bertblankenstein3738]

Sigh., the problem with comments is that things have already transpired and it is too late. That was something that I saw coming. On the first pass I thought it might have been a chip on that flange.

[@philhunt9297]

^this^ in all it's glory and representation Not a machinist and only a basic service & maintenance of motor vehicles qualification taken nearly 40 years ago 1 - spotted the issue with turning on lathe [correct Bert - first pass 22:39 it's chipped] 2 - water pumps are replaceable parts whereas pulleys less troublesome [machine off pulley not the pump] 3 - nothing can be done to fix either issues except treat them as a learning experience What I can't understand is why a vehicle specialist engine builder would send in the pump - it aint Adam's fault...he knows everything for precision machining and was just doing what the customer requested but shouldn't need to think is this the right part to machine............but I do know for sure 100% that if he reads these comments he won't be doing another water pump without double questioning the customer because he is a professional.

After looking a pictures of stock gaskets, I don't think they will work with the larger holes. Hopefully there is a large enough flat surface on the motor to take a homemade gasket.

[@Paul-FrancisB]

Exactly the ports in that casing are angled so taking that much material means they are unlikely to make with the dimensions of the original matching surface unless the plate will be machined as a transition piece between the old and new surfaces

[@Grantherum]

Personally, I would've rather had them replace the pullies on the other pieces of equipment, than to shave the waterpump assembly, since pully replacement is much nicer to the sealing surfaces than milling down the mounting surfaces of the water pump. But, they can do them, and I guess milling down the water pump is 1 part vs potentially 6-9 pullies.

[@scrappy7571]

it's not a water pump. It's a non moving housing, the water pump bolts to this.

[@MicrophonicFool]

Turning Odd shapes sure looks sketchy on the surface

[@tlum4081]

My thoughts too. Actually my first thought was to use the mill. It's not like the only tool Abom has is a hammer and everything looks like a nail!

You mean other than the part where the machined teference plate is easily grabbed by a chuck, and the painted lugss prevent it from being dropped directly on athe lathe table. Setup time costs.

Bridgeport and Silicon. Can fix anything. The lathe is an odd choice but for content I get it.😂

And also you remove all the material you want but that flange for the hose is still gonna hit.

[@FRANKBURNSONE]

Those two WP housings are not the same. The original housing, where the impeller sits looks to have a lager opening. Could be the camera angle.

[@_Otaku-kt8be]

No I'm pretty sure they're different too

[@wagnerfarm5550]

Best option would’ve been to machine a pulley with the correct offset. Water pumps are a wear part and have core value as well. A pulley is expected to last through the life of the car. Maybe 4-5 water pumps.

[@simonsben]

440 engines use a four bolt pump that bolts into the round flange - what he is machining is the housing that the replaceable pump bolts into. This part is not the wear item.

[@JamesRook]

A really, really bad idea. If you have to machine the water pump to fit the motor plate there is definitely a mounting problem with the motor plate, not the pump. The water pump is an item that commonly fails and gets replaced all the time on regular vehicles, much less with race engines that put more wear and run higher RPMs. Unless they send you a bunch of pumps to modify and keep with the vehicle for when (not if) the pump fails, this is not how you do it. You can't get a replacement pump from the local parts store now so the engine is useless once you get a failure. I also have wonder whether the thermostat housing is going to clear the timing cover and front of the manifold now since it's inset.

[@Patric-Kole]

If you didn't machine the pump, the pulley will be 1\4 inch to far forward of the crank pulley. Unless you shim the crank pulley and all the accessories that 1\4 inch forward as well.

[@silasmarner7586]

@@Patric-Kole Correct. The peanut gallery just wants to rant and rave... Rah rah THIS.... and rah rah THAT. .. without considering all the facts.

[@rprice7670]

The first thing is that this is the housing for the water pump. The water pump is only 4 bolt holes with a o'ring. The next is the motor plate is 250 thous think so it will take up what he removed. This will allow the pulleys to align with no problem.

[@JamesRook]

@@Patric-Kole Two ways to fix that. A flipped or offset step pulley if you must run a belt drive, or do what many racers do and run an electric water pump with off the shelf parts. I understand the misalignment caused by using a motor plate, but this is not the solution. The motor plate is incorrectly mounted and positioned.

😳0,0005 ? What's the problem? 0,0005 ??? If the housing gets warm or cold, you get a different measurement again. Now so much material is missing that it is too short. Now it's no better, just shorter.😂😂
