There is a new high flow charge pump the pre-charges the main hyd pump and also increases the lube to the trans and differential. Our original took a dump and snapped te small hex shaft that drives it. Gears were junk, as well as the bushings. They replaced the shaft without checking the pump, and it didn't last 3 hrs before it was trashed. You have to remove the rockshaft assembly to get at the pump. The new one is quite a bit bigger and a PITA to install, but it fits. BARELY.
To remove the main pump, you'll have to remove the front axle to drop it from the bottom, or take it out the top. Either way sucks. Fittings are hard to get at. Not much room. Either way, replace the pump drive coupler and bushings. You'll thank me later.
This 4430 has ground TONS of hog feed, hog cart duty, pulled a field sprayer, has run the grain vac for over 10 yrs, hauled TONS of manure, small grain cart. Some tillage. Mainly used to mow road ditches, run the vac and haul manure now.
Also have a '65 4020 diesel that is on its 4th tach. Who knows how many hours are on it. The last one I replaced had almost 9000hrs on it when it croaked. Last engine overhaul was ~24 years ago. Still starts great in the winter, and no block heater of any kind on it. Boss is too cheap to buy one. Tiny sniff of ether in the winter, and its running.
