    Capacitor testing

    I know there are some members with solid electrical backgrounds and I need some help troubleshooting my mig welder. It is a 100 amp unit, 110v. Lately it is not working well. It seems to not be generating a hot arc like it used to, it also feeds the wire slowly. The symptoms seem to have...

    Dirty Oil- PCV Fail?

    I drained the engine oil and collected a sample of strange looking, non-magnetic, black particulate matter from the drain plug. I drove the truck 12 miles and drained a sample of oil and it was black. I drained it again and drove it 6 miles and it was very dark. I have not driven it since the...

    39 brake shoe retainer clip

    Does anyone have a source for the brake shoe retainer clips that fit a 39 rear backing plate? The usual suspects have a postwar clip but they don't fit. I expect to be back in there shortly and know at least 2 are broken. Thanks.

    Front axle king-pin bolts

    I replaced the kingpins and bushings on my 39 pu last December. This morning I had the front jacked-up and noticed that both king pins were loose in the axle and the tapered bolts securing the kingpins were not very tight. I snugged the bolts and the play between the kingpins and axel is gone...

    Odometer Spool Disassembly Question

    I removed the speedo from my 39 pu because it was making noise. The odometer and tripmeter were inoperative also. I have cleaned all the hardened grease and lubed the gear-train. What I have found is it appears the 100s and 1000s wheel on the odometer spool are stuck. It looks to me like...

    Passenger Door Latch Mechanism

    I've got what appears to be a 1940 passenger door on my 1939 pu. The inner passenger door handle moves one way to open and the other way to lock. When I disassembled it there was a chain attached to a spring and stud on one end and the handle linkage on the other. It looked to be an...

    Why would someone do this?

    I drove out to Bonneville yesterday and among the many curiosities was this one. Any idea what's going on with the cylinder heads and intake? It's half a flathead, sort of.

    Wheel Cylinders Where Art Though?

    I put USA kits in my 1939 pu wheel cylinders and three leak, due to corrosion pitting I could not hone-out. I searched the old threads and they suggest that I should buy new USA wheel cylinders which are available at NAPA and C&G but these threads are years old. NAPA's website has no parts...
