Tandem Pump Removal
! WARNING !
Hot oil can cause personal injury. Lower all attach-
ments and make sure the oil is cool before removing
any components or lines.
Remove the oil filler cap only when the engine is
stopped and the filler cap is cool enough to touch with
your hands.
NOTICE
Collect and contain liquids in a suitable container. Dispose
of all liquids according to local regulations and mandates.
Note: During disassembly, cap all hoses and fittings to
prevent fluid loss and contamination of the system fluids.
1. Remove the charge pump and the auxiliary
pump.
2. Label and remove all the hoses and tubes from
the tandem hydrostatic pump. Be sure to cap all
hoses and fittings.

3. Secure pump by chain or floor jack to prevent it
from falling once mounting bolts are removed.
4. Remove the mounting bolts (with spring lock
washer and flat washer) from either side of the tan-
dem pump. You will need to keep sliding the pump
away from the engine mounting plate as you loosen
the bolts to prevent the bolt head from bottoming out
on the pump.
