Mopar Water Pump Housing - Machining .240" off Thickness

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.

At 6:00min the first job I would have done here would be to pivot a straight edge across one of the flats and that inlet/outlet would have immediately shown up as being in the way. Why would I have done this ? Because at my age I have found that nothing is as simple as you would like at almost every turn. The biggest single issue with the machining of any weird shaped part is somebody else will have always made some bit stick out where you don't want it.

I'd say "Close to parallel" is good enough. The pulley belts aren't that sensitive to a couple thousandths difference between front and back housing planes. The more important thing is the same plane for the block inlet flanges. (even then a thicker gasket and sealant is pretty forgiving on tolerance mismatches.)

My guess is it is about the ease of machining both sides the same height. Single op, as opposed to mill with the available(?) tools. So chase the correct size once, not twice with the inevitable deviation between the two attempts.

[@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.

[@whitt2274]

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

[@jsteifel]

Adam, your use of the height gauge may have been flawed. I think a test indicator should have been put in there and moved to zero each time on the test indicator. Then do the delta. That way you are not pushing too hard or modifying the height by your hand. While it worked, the scribe is not a good way of measuring. The test indicator gives a perfect indication of when you have reached the same point with the tip, then read the height gauge. Just my opinion..

[@anothermidlifecrisis]

Its a part that will grow by 10 thou or more with heating, and its a nonuniform shape, so its growing in all sorts of directions. A few thou lost with how he measured isn't bad.

[@jsteifel]

@@anothermidlifecrisis I think you miss the point. And this has nothing to do with it in use, only with it being machined, and his process of measuring is flawed. For this application it probably won't matter, but for machining in general that creates too heavy a hand, and too much chance for an incorrect reading.

All this precision just to achieve V belt alignment seems a bit much. I do appreciate all the considerations to clamp and hold this unique part for machining. I wonder what the tolerance was for the machining of the original part. I have built a 440 Mopar and they do not require this level of accuracy. This is truly a difficult part to machine mostly from a clamping perspective. That is the lesson of this video, the creativity required for clamping the work piece. Still makes for an interesting and instructional video.

[@WreckDiver99]

Kind of why I like Keith Rucker and Steve Summers (hope all is well with him and the family, he has been absent for a LONG time with that new grandbaby).

Customer wants a bit off the Top of the Pump Housing (NON Impeller side) from a Machinist then that is what they get. The 2/3 (guess) of post here seeking to find fault with that should take a chill pill. The tiny changes to the porting just don't matter hydraulically in any meaningful or measurable way. This is no more or less different than doing a cut and shut of rigid plumbing on any water pump in any industry.

[@Onceayoungidiot]

First cut, there was a shiny spot on the flange. Surprised you didn’t see that. That said, fascinating stuff & a sweet job overall. 👍 I think the customer will have to modify the gaskets on the machined part, though: looking at the old one in the last photo the standard gasket for the upper (on the screen) connection will overlap the new port size.

[@grahamstretch6863]

I told my wife you were going to hit the thermostat housing while you were fiddling with the plastic block, but figured I was wrong and it was just not the right camera angle for determining the clearance. I am really surprised that you didn’t notice the proximity of the tool to that edge whilst you were checking and touching on as you had the perfect vantage point , I thought I was seeing the first sign of contact as you were looking at the finish after the first cut at around 23:29! 😢

[@c0mputer]

Same here! I was thinking it’s an illusion and there was plenty of clearance but lo and behold it wasn’t an illusion and it started to interfere. He’s just lucky that housing wasn’t actually proud of the faces he was machining. Could have chipping something or spun the part in the lathe marring up the surface the chuck jaws were holding on to. Definitely a mill job from the get go.

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

[@marshalllarson8970]

Nobody in the trade, and probably everyone else, thought of using the lathe. Besides the obvious flaws, holding on to the finely machined housing bore with hard jaws is just poor practice.

[@bradywilliams2666]

Reading the comments it is apparent most don't know what a engine plate is. It is a thick plate that bolts to either the front or back of the motor and reaches out to the frame. When bolted on the front it is sandwiched between the water pump and block. It is used in place of the normal motor mounts on the side of the block. In this case the plate is a 1/4" thick pushing the accessories out of alignment. Taking the 1/4" off the water pump puts them back in alignment. That being said and engine plate and restoration does not go hand and hand.

You would spend that just setting it up on the mill, making sure its level having a good area to clamp,etc. Dont get me wrong if it was a nice square part that could just be chucked in a vice mill everyday of the week from the off. Just a oversight and caught it before the parts wrecked. Fixed it moved on and got the job done. Honestly done understand why people have to be so negative.
