FILLING OF HYDRO-LECTRIC
RESERVOIR
from rear seat back panel and remove shield
from pump and motor, if present.
This procedure virtually eliminates discharge or
spillage of hydraulic fluid and possible trim dam-
age while filling and bleeding system.
Fabrication of Rubber Filler Plug Adapter
1. Obtain a spare
rubber
filler
plug
(Part
#7596442).
2. Cut approximately 1/2" off male end of plug
(end inserted into reservoir) to permit in-
sertion of tubing as shown in sketch.
3. Obtain a 2" length of metal tubing 7/32 O.D.
x 5/32 I.D.
4. Insert
reworked plug into filler
hole in
reservoir.
5. Insert metal tubing through hole in reworked
filler plug.
NOTE:
Attached sketch illustrates fabricated
filler plug adapter.

2. On "B-C & F" body styles, remove rear seat
cushion and back.
3. Place absorbent rags below reservoir at filler
plug. Using pliers, slowly pull filler plug from
reservoir.
IMPORTANT:
When installing new or over-
hauled motor and pump assembly as a bench
operation, fill reservoir with hydraulic fluid.
This priming operation is necessary prior to
performing the following steps in order to
avoid drawing excessive amount of air into
hydraulic system.
4. Install filler plug adapter to reservoir and
attach four or five foot length 5/32 inch I.D.
rubber tubing or hose to filler plug tubing.
5. Install opposite end of hose into a container
of GM Hydraulic Brake Fluid Super #11 or
equivalent.
NOTE:
Container
compartment area
should be placed in rear
on "A" bodies and rear
floor pan on "B-C & F" bodies, below level of
fluid in the reservoir. In addition, sufficient
fluid must be available in container to avoid
drawing air into hydraulic system.
6. Operate top to down or stacked position. After
top is fully lowered continue to operate motor
and pump assembly (approximately 15 to 20
seconds), or until noise level of pump is
noticeably reduced. Reduction in pump noise
level indicates that hydraulic system is filled
with fluid.
7. Operate top up and down several times or until
operation of top is consistently smooth in both
up and down cycles and no further air bubbles
are exhausted in container or fluid.
8. With top in down position, remove filler plug
tubing and remove filler plug adapter from
reservoir.
9. Check level of fluid in reservoir and re-install
original filler hole plug.
NOTE:
Fluid level should be within 1/4 inch
of lower edge of filler plug with top in down
position.

DO NOT OVER-FILL.
