    IH 424 Wiring question

    Actually, I said I thought it might be a TVS diode, which is two diodes back to back ->||<- It only passes voltage that exceeds the breakdown voltage of the two diodes, so during normal operation it blocks voltage in either direction. If it sees a high voltage (anything above the specified...

    IH 424 Wiring question

    Jim and Jim - the idea of a turned back wire seems correct to me. I noticed a few wires on the existing harness that went nowhere, that is probably exactly what those designate. I replaced the original alternator a long time ago with a 1-wire alternator, so no need for the regulator. It...

    IH 424 Wiring question

    Maybe acting at a TVS diode? I'd say it's definitely a possibility. I'm considering replacing the coil with one that has a built-in resistor, that would simplify things a bit.

    IH 424 Wiring question

    I assumed that this diagram did not include any lighting - there's no lighting switch, headlights or taillights shown at all. But, it's an odd diagram - shows the Ammeter, shows the Oil Pressure gauge, but doesn't show the Tach! No legend at all in the manual for the 424 (I have the I&T shop...

    IH 424 Wiring question

    I'm getting ready to re-wire my 64' IH 424 (gas) tractor due to multiple issues. I have a shop manual, but the wiring diagram shows a few thing that has me a bit confused. The areas on the image circled in red show what I'm confused about. If anyone has some thoughts, I'd sincerely...

    injector and compression question

    Those injectors were a nightmare to remove! Took me the better part of a day to coax them out. I'll try the bolt idea, but I did scratch the bottom of the bore with a screwdriver, and it definitely does not appear to be copper.

    injector and compression question

    I have some old injectors here I'll modify, just curious is there was something off the shelf. When I pulled the injectors, there was no crush washer in the bore, which I found very odd. I'm planning on adding them, just wanting to know if anyone else has seen this.

    injector and compression question

    I'm slowly bring a mid-70's MF300 loader back to life. Motor is a Perkins AD4.203. I pulled the injectors, there are dust seals at the top, but no sealing washer in the bore - is this typical, or am I just not able to see the washer? Also question about testing compression - since the...

    MF300 air intake boot

    Anyone know where I might be able to find this particular part? Not a huge deal, it connects to the exterior air intake grill to the filter. The grill might keep wasps out of it, but not much else, so I'm not convinced it's a must-have, but as shown, it's ripped. It's on a mid-70's MF300...

    MF300 hand throttle control

    I had the fuel tank off, figured I'd see if I could repair it - turns out it was simple enough to remove, clean up, and put it back - works fine and dandy!

    MF300 hand throttle control

    Well, I'll be - never thought to look there! Found a DORMAN that looks like it will do the trick. Appreciate the advice!

    MF300 hand throttle control

    Please see image - my hand throttle control on my MF300 loader no longer locks (pull and rotate to lock). Having no luck at all finding a suitable replacement. I'm hoping that I can disassemble it and repair, but if I could find something similar, I'd be happy to purchase. Any ideas where I...
