Default Re: John Deere 4300 complete rebuild

These pix show the tractor after it was brought home on a rollback
truck. The place I bought it from sort of put it together with the parts
they could find, so at least it could be moved. Numerous parts had been
taken off to fix other 4300s that were in the active rental fleet. Since the
range shift was broken and the transimission was in gear, I had to pull
the tractor off the truck deck.

The 2nd photo shows the back end of the tractor, and the broken right
axle housing. I was surprised to find out this casing is cast aluminum....not
a good design decision, IMO. The lower 3-pt arm attachment has pulled
out. The middle section is cast iron or cast steel, which is the opposite
of the earlier 955, which had Al center and cast steel axle housings. The
Kiotis I have owned, and some of the Kubotas used all steel back there. I
would hesitate to buy a tractor this size with Al axle castings. (I do plan
to mount a backhoe on this tractor.)

3rd photo shows a bent loader cylinder rod....these guys are only 25mm
in diameter! Too small, IMO, which is supported by the fact that many
many of these have been bent. Attempts were made to protect them
(see the green bracket?) with limited success. This is the 420 FEL;
maybe the larger 430 FEL is more robust?

Finally take a look at the the two independent hydraulic pumps....no
flow divider is used, which IS the case on a lot of other CUTs this size. Nice.
