    420w hydraulics leaking badly

    Thanks Timar- that makes sense. Puzzled why they leak so much worse now than 5-6 years ago, but I guess that old seals will do such things, and it"ll be good if it is just those control shaft seals. Just looked at the diagrams in the parts book and it makes sense. I had the Touch-O-Matic apart...

    420w hydraulics leaking badly

    Thanks It's sub-zero here and I do not have any heated workspace, so would need to wait for a warm spell. Wondering if there are any "common" things that could explain what I have going on. It really didn't leak anywhere but the rockshafts before it sat.

    420w hydraulics leaking badly

    I have a 1956 420W that I have owned since 1998; engine and driveline are strong, and I've re-done clutch, brakes, radiator, and some of the hydraulic seals. 'Other chapters of life' resulted it it sitting for about 5 years outdoors until this past fall. I've revived it without difficulty and...

    Thanks for the input- that's very encouraging! Will run it some more and see what I can find.

    70 ignition keeps failing

    In my opinion, skip the all-electronic changeout models and get something called a Dyna Ignition Booster DBR-1, primarily marketed for motorcycles but will work for tractors- it uses stock points to switch a transistorized circuit that takes nearly all of the load off of the points and...

    430w updated rock shaft and housing

    Could you please point me to a thread or website on the updated seals and how to machine for/ install them? My 56 420W has no seals and should be called the Leak-O-Matic, which is especially bad because I have a loader on it, and due to the loader, hyd. levels vary.

    JD 420 hyd. pump accidentally run w/o enough fluid...

    Hello all- Recently revived my 1956 JD 420W after other complications in life had caused me to (regrettably) leave it sitting for a spell of a few years. The good news is that with some minor tuning up, it runs every bit as well as it ever did (it has great compression, good oil pressure, and...

    JD 420 hyd. pump damage- run dry?

    Yes, the filter IS good for over 1200 PSI; it's a Donaldson Industrial filter sourced from Applied Industrial. When I got this loader its history was unknown and it was a bit scruffy, and I didn't want any scuz in the loader's system passing into my tractor's hydraulics, so went to the extra...
