GENERAL INFORMATION
Using the proper guidelines and precautions, all four
model Electro Lift
®
units are easy to disassemble and
reassemble. Figure 3-1 (page 32) is an exploded view
which applies to all four models. It should be used as
the primary reference for proper reassembly. Where
necessary, this section includes additional information,
photographs and illustrations to assure proper and
efficient repairs.
UNIT DISASSEMBLY AND REASSEMBLY
Model E-46, E-46H, and Power Angling units with the
exception of the Power Angling Valve Assembly, the
parts and disassembly / reassembly procedures are
common to all models.
Many repair procedures, including removal and
replacement of the “B” and “C” Solenoid Valves, can
be accomplished without removing the unit from the
vehicle. While Figures 3-2 through 3-62 show the unit
clamped in a vise, make all possible repairs on the
vehicle when possible.
NOTE: Pump Assembly should not be disassembled
since it cannot be serviced with the exception of the
pressure relief valve (pages 19-20) and pump shaft seal
which is covered separately in this section.
Motor should be taken to the appropriate (American
Bosch or Prestolite) authorized service station in your
area for all parts and service with the exception of brush
replacement. Procedure for American Bosch motor
brush replacement is covered separately in this section.
Disassembly
See Figures 3-2 through 3-11 (pages 34-36), Figures
3-25 through 3-31 (pages 39-41) for important
disassembly points on any of the four models.
See Figure 3-12 (page 36) for important disassembly
points on the E-46 and E-46H models.
See Figures 3-13 through 3-24 (pages 36-39) for
important disassembly points on the Electro Lift
®
units.
See Figures 3-42 through 3-48 (Pages 44-45) for
Crossover Relief disassembly.
Reassembly
See Figures 3-31 through 3-41 (pages 41-43) for
important reassembly points on any of the four models.
See Figures 3-49 through 3-62 (Pages 46-49) for
Crossover Relief reassembly.
Additional Reassembly Points
O-Rings- Coat liberally with hydraulic fluid and
position carefully to minimize possibility
of damage during assembly.
Fasteners- Torque all fasteners which are specified to
insure proper reliability and prevent
damage due to over-tightening.
PUMP
Shaft Seal Replacement
NOTE: Do not disassemble pump assembly.
1. Remove motor as shown in Figures 3-4 and 3-5
(page 34).
2. Using an appropriate tool, pry out the original shaft
seal, being careful not to damage the shaft or pump
housing.
3. Liberally coat the replacement seal I.D. with
hydraulic fluid and apply a very light film of
Permatex Form-A-Gasket No. 2 or equivalent to
the replacement seal O.D.
4. Carefully slide the replacement seal
(metal side up) over the shaft until it is squarely
against the pump housing.
5. Center a 11/16" hex deep socket over the seal and
use it and a plastic or leather mallet to squarely
drive the seal into the pump.
6. Replace the motor as shown in Figures 3-39
through 3-40 (page 43).
