Control valve
31
MTD uses three different control valves on log splitters.
The size of the log splitter determines which valve is used.
The three different valves are identical on the outside.
Whenever testing or replacing a control valve, verify the
part number of the valve on the splitter is the one listed in
the parts drawing for that specific splitter. The valve part
number is stamped into the end cap of the valve.
See Figure 4.1.
NOTE: The numbers were filled with white paint to
improve visibility for the picture.
NOTE: The only parts of the control valve that are service-
able are the spring cover, lever, master link and the
lever bracket.
NOTE: DO NOT use teflon tape on any fitting on a MTD
log splitter. Pieces of the tape can get into the sys-
tem and damage the valve or the pump.
Control valve removal/replacement
To remove a control valve:
1. With the engine turned-off, relieve hydraulic pressure
from the system by moving the lever on the control
valve through its full range of travel.
2. Thoroughly clean all dirt and debris from around the
valve.
NOTE: Any dirt or debris that gets inside the valve can
destroy it.
3. Place a suitable container under the valve to catch
the fluid that will leak out as the hydraulic lines are
removed. See Figure 4.2.
4. Loosen the hose clamp on the low pressure return line using a 5/16” wrench.
5. Disconnect the low pressure return line.

Hydraulic fluid under high pressure
can be dangerous. A high-pressure
hydraulic fluid leak or spray can pen-
etrate the skin. If this happens, seek immediate
medical attention to reduce the risk of blood poi-
soning leading to death or limb amputation.
