6-2. LOG SPLITTER MODEL 632
(See Figure 6-3).
6-2.1 The Model 632 log splitter will split hardwood
logs up to 26 inches long. It is trailer mounted
with a hitch that accommodates a 1-7/8 inch
ball for towing. The wheels have high-speed
tapered roller bearings. For a summary of
specifications for Model 632, see Table 6-1.
6-2 . 2 Log Splitter Operation.
1. The two-stage log splitter pump has one large
and one small gear section using common inlet
and outlet ports. Below a preset pressure
(called unloading pressure) a check valve
between the two gear sections allows both
flows to combine. Together the two gear sec-
tions create a large volume flow which pro-
duces rapid cylinder movement under low load
conditions. See Figure 6-4.
2. Above unloading pressure, a pilot pressure line
(which simulates actual pressure at the cylin-
der) activates the unloading valve, which
causes the flow to bypass the large gear sec-
tion and return to the pump inlet area. The
small gear section is now operating alone and
will generate the higher pressure necessary for
the actual log splitting operation.
