Note: Before beginning the removal process, you may want to make a sketch of
the plumbing and component configuration to aid in re-assembly.
2.
If not already done, remove necessary body panels and framework to
gain access to the pump compartment and RSDM pump assembly.
3.
Make sure there is sufficient clearance above and around the apparatus
to perform your service requirements. Obtain access to the pump and
gearbox assembly by removing or disconnecting other equipment as
needed, e.g., valve operators, discharge and suction piping and valves
that would interfere with pump removal.
Have clean disposable shop rags and oil dry handy. Also disconnect
cooling tubes to the pump, air lines, electrical switches and tachometer
cable as required.
4.
If you are servicing the oil seal only, it is not necessary to drain oil from
the gearbox.
However, if your service is internal, i.e., input shaft assembly compo-
nents, you must drain oil from the gearbox - remove the magnetic pipe
plug. See Section 4: Preventive Maintenance, heading “Replace Gear-
box Oil” on page 52. Have a suitable container available to collect the
fluid, approximately two (2) quarts (1.9 liters).
5.
With the pump assembly properly supported and balanced, remove the
twelve (12) 3/8”-16 (M10-1.5) screws and hardware that secure the
assembly to the engine mounting. (See Figure 6c-2: “RSD Engine Drive
Option,” on page 100.)
Always use proper lifting and support apparatus (jacks, hoists, straps,
chain, etc.) when servicing the unit. Exercise care when using chains to
protect finished surfaces from scratches.
6.
Carefully remove the assembly from the engine mount elastomeric drive
disc.
7.
Move the assembly to a clean work area and clamp into a suitable and
stable holding device. It is recommended to maintain the lifting device
connected to the pump assembly.
8.
Remove the eight (8) 1/2”13 screws (two sets of four, of different
lengths) and hardware securing the flywheel housing to the gearbox
housing. (See Figure 6c-2: “RSD Engine Drive Option,” on page 100.)
