gt14rider 797 #101 Posted April 10, 2019 I'm still down to the rafters, builder 60 years ago cut rafters 3/4 way through and put a small patch around pipe. Have to box in rafters and cut pipe to fit through box, put new subflooring, bla,bla,bla. Dam it JIM I'm a mechanic not a carpenter. 2 Share this post Link to post Share on other sites

Sarge 3,463 #103 Posted April 10, 2019 For building high load pulling tools, splitters, and such other devices - I use these as a cheap source of high strength forcing screws. https://www.surpluscenter.com/Power-Transmission/ACME-Thread-Lead-Screw-Nuts/ The ACME thread design can handle much higher loads than any SAE or Metric 60* thread design. Just be sure to keep them oiled and be careful in how you weld the nuts to avoid embrittlement. I've had to build countless pullers, pushers, splitters and other tools to work on things that were designed to not be serviced, but replaced. I don't accept that, so I rebuild a lot of things that for the most part aren't all that tough to do. Just takes time and some thinking outside the box.

gt14rider 797 #104 Posted April 10, 2019 Thanks for link, acme thread would be nice. Ouch taps are a little pricey Share this post Link to post Share on other sites
Sarge 3,463 #105 Posted April 12, 2019 ACME thread taps are not cheap at all, even the imported junk Chinese versions. Due to the thread design, it requires either a 2-stage tandem tap or 2 different taps to form the threads. Semi-square, square, round and other types are even worse. Far cheaper to just buy the nuts and weld/capture them when building parts or tools. The lead screws from Surplus Center are only 1018 steel, so they can't take the full rated load of that thread design but are far stronger than standard 60* cut threads. The nuts they sell are some really nice alloy - so no fear of welding them there but they are hardened. Best to use 1018 or ER70 filler rod and some preheat - right around 250*. I've built a ton of tools, screw driven devices and such with these parts - the thread design clogs far less, handles a much, much higher load force and can take shock loads far better than anything else for the money. Also, you'd be surprised what a cheap 3 ton, short hydraulic jack can do as well. Even one of those cheap knockoff Porta-Power units has a short ram that is useful.

gt14rider 797 #106 Posted April 13, 2019 (edited) .. Well thought about a Jack, that's why square plate is so big, to be able to bolt a Jack on if bolt didn't work, ( got idea from meadowfeilds post, in tools and equipment) but my use your idea of welding acme nut to plate, thanks for idea Edited April 13, 2019 by gt14rider Share this post Link to post Share on other sites
gt14rider 797 #107 Posted April 16, 2019 Welded up parking paw, ordered differential parts, should get bearings Wednesday Share this post Link to post Share on other sites
daveoman1966 3,762 #108 Posted April 16, 2019 (edited) That looks like a new Parking Pawl....nice weld-up. The reason this gets 'ground down' is from yanking up the Parking Brake while in motion. Every time someone does a 'panic stop' like that, a bit of the pawl gets chipped off...worn down and...guess where the filings go... floating thru the entire system, scarring and damaging the soft BRASS components like the piston slippers and valve plates. It is kinda like throwing your car into PARK, while moving. Don't get me wrong...I'm not lecturing, just want to get this out there in Red Square land...so all will know. Don't EVER pull up the Parking Brake lever while moving. There is even a decal warning of this. Edited April 16, 2019 by daveoman1966 2 Share this post Link to post Share on other sites
gt14rider 797 #109 Posted April 16, 2019 It was broke when I got it honest, it wasn't me. It will be nice to be able to set break not throw a block down or run after it. 3 Share this post Link to post Share on other sites

Check out the bearing seams ok, I'll probably go a head and use it. I'm a little anal to always replace with new bearings Share this post Link to post Share on other sites
gt14rider 797 #114 Posted April 29, 2019 Little progress on tranny, cleaning things up. Got the lift valve cleaned up with new seals. Cleaning up cases, seals and bearings should be here in a couple of days Share this post Link to post Share on other sites

gt14rider 797 #117 Posted January 1, 2020 Started work on this again. Does anyone know a good source of hydraulic hose fittings and what size. Might try and make some if price is right or buy some from A-Z Share this post Link to post Share on other sites
