Acme Machining

Acme Machining

My name is Todd Hopkins. I have been a mechanic for over 45 years and started machining while working on parts that did not fit properly or had to be made because they were not available. Name of my channel is Acme Machining for the small village in Alberta Canada that I live in. KZread has been a great learning tool for me and I hope I can share some of my skills with others.

    Yup got a Ram 1500, 5.7 Hemi. Manifolds need this done to them. Well I replaced the passenger side with a brand new one, so it'll be warping soon I'm sure. Driver side Id like to have this done to it, instead of having to keep buying these manifolds that are just gonna warp again. How much would you, or do you charge for this? What's your price per manifold? I know of a few machine shops near me, & what would be a good guesstimate price wise? Thanks, & good job on the manifolds!

    Thanks for watching & subscribing. I charge $60 per manifold to belt sand, or $100/hr if it has to go on the mill. Usually do at least 2 pair per week. Haven't heard of any needing redone in over 5 years, so it must be working.

    Why bother taking a measurement of the old pinion if you're installing a new pinion?

  • @acmemachining

    Never ASSUME. That will bite you when you least except it. If they are exactly the same, we would just remove and replace with out any measurements or concerns. Parts are never exactly the same especially gears and bearing. That's why they have shims and set-up procedures.

    ​​@@acmemachiningright so again why are you putting in the old shims when you have to re shim them anyway with plus or minus shims?

  • @acmemachining
    @acmemachining19 күн бұрын

    Shims can be re-used. Most times you have to stack shims to get the right height you need. Rarely do you have one of each size, but combinations will add up correctly. Always save your old shims for next time. A lot of shops trade off shims to get what they need.

    Great video I'm about to dive into this for the first time on a gm 12 bolt posi thats still mounted in the car, not looking foward to popping the carrier in an out 20 times, sucks this pinion didn't have a # on the face or any other markings cause I would have liked to see how that matched up or how you did the math using a calibration tool. My thought is just to mount a square plate where the carrier bolts up then just measure to the face of the pinion, seems it takes a bunch of math an room for error right off the table. Is the # on the face of the pinion the depth from the face of the pinion to the center of the carrier itnis from the back of the spacer behind the pinion to the center of the carrier?

    The marked numbers (you found 2) are gear set matching number to keep ring and pinion in a set during manufacturing / packaging, the other is pinion depth usually within the range of +4 to -4 in thousands of an inch

  • @acmemachining
    @acmemachining20 күн бұрын

    If you are taking apart a good work diff, and just changing to different gear ratio. You can use any repeatable refence surface. The important part is getting the calculated measurement of the bottom of the pinion where the bearing or shim sets against. Number on the pinion is usually stamped or scribed on the top of the pinion gear or on the shaft below the large bearing. My reference of top or bottom is if you are looking down into the diff like I had it is sitting in video. I don't like saying front or rear because that depends on where you are standing or possibly 4 wheel drive diff. The marked numbers (you found 2) are gear set matching number to keep ring and pinion in a set during manufacturing / packaging, the other is pinion depth usually within the range of +4 to -4 in thousands of an inch. A plus number needs to sit deeper in the diff, so a thinner shim. Hope this helps. Remember the final check is always looking at gear pattern in marking paint.

    25.4mm equals 1 inch. Pinions markers on older North American vehicle are in thousands. Always check for spec in a good service manual.

    What about bar sag and indicator spring pressure? Does that have to be considered?

  • @acmemachining
    @acmemachining26 күн бұрын

    I don't worry about bar sag or indicator pressure. A good indicator doesn't have enough pressure to move a good test bar. And bar sag can be checked with indicator mount to bar end against tailstock center. If bar sage is an issue you need a better test bar or spindle bearing maintenance. Lathe is cutting much truer since adjusting head stock, so that is proof enough for me. Thanks for watching & commenting. Hope you subscribed!

    That's all fine and dandy how your doing that but the pinion depth is pretty critical and all those measurements your taking off of different surface's your liable to be off a few thousands. Also if the rear-end has been worked on before who knows if it was set up right to begin with. That rear-end did not come out of a ram 1500. It's a Dana 60. They never installed them on a 1/2 ton ram. 3.125 is the pinion depth on a 60. Just get the right tools for the job instead of cobbling something together. Setting up axle gears right is pretty important if you want them to last. Especially if you using it to off road or pulling.

  • @acmemachining
    @acmemachiningАй бұрын

    Title of video is about using simple tools, not how to spend a thousand dollars on tools to save 5 hours labor. This diff came out of a 2012 Ram 1500 VIN 1C6RD7GT8CS118883 customer still has the truck. Diff is also too small for any severe off roading or pulling. Final check for any diff work is pattern checking, so if my method got a totally previously messed up differential to within a few thousands on the first try, to be corrected after checking pattern with gear paint, good job.

    That diagram was not for this differential, it just shows the measurement and where they are being taken.

    Nice job. The biggest thing for me is being ‘self taught’ mostly because any possible instruction in my past has been trial-and-error mechanics that act like it’s a secret black art because they can’t explain what they are doing or measure it. I’ve done a few diffs but knew just enough to get it right and understand why. But great video that affirms my knowledge and taught me a coupla things. Between this and metalshaper’s vids I feel like the next one I do (Dana 30 of my own) I will know exactly what I’m doing and why, and you just saved me $800 :) I actually found this video because I realized it’s just numbers and I thought it likely there was something like this method which would work. So you saved me a bunch of money AND saved me from reinventing the wheel.

    When I use this information to try to gauge my pinion depth, I'm getting some strange numbers. Based on what I've measured and calculated, I should be using 0.158 of shims. Does that seem unusual? That's the factory shim, plus nearly every shim that came in the kit I got. If I install that many shims, I can't get any backlash at all. So obviously I'm doing something wrong. I just don't know what. My pinion has the number 092 written on it. The ring has a D22092 on it. I'm assuming my mounting depth then is 5.092? The pinion is 1.99 without a shim, the center of my axle is 2.44 from the surface of my diff housing. Thanks

  • @acmemachining
    @acmemachining2 ай бұрын

    What was the original measurement of pinion before removing and do you have the right spec for pinion depth? Most pinion shims are under 0.035". If you can't get spec for your diff's pinion start with factor shim and check contact pattern with marking paint. If you have measurement from original pinion you can select shim through calculating difference. Some manufactures done give pinion depth spec, they just give what you should be measure with their special tools. I hope this helps. Do force anything and repeat until contact pattern is correct.

    There is something very loose in your setups. When you're winding the compound back you're taking almost as big a chip as on the way in. Maybe you're pushing on the compound when you're winding back. Use a drill to drive the compound, you'll get better finishes and more accurate cuts. Holding onto the machine like that is a bad idea.

    Amateur question: when you set the block up on the table, it seems to me that you are automatically accepting the undersurface (which touches the table) as "true and correct" and measuring the deck surface against that. Is there a potential for being mistaken in that assumption, and how would you detect that and compensate for it?
