ELEGTRICAWACUUM SYSTEM
DIAGNOSIS
When diagnosing problems in the electrical sys-
tems of the air conditioning system, consult section
8A.
LEAK TESTING THE REFRIGERANT
SYSTEM
Whenever a refrigerant leak is suspected in the
system or a service operation performed which results
in disturbing lines or connections, it is advisable to
test for leaks.
Liquid Leak Detectors
There are a number of locations (fittings,
valves, etc.) on the air conditioning system where a
liquid leak detector solution may be used to pinpoint
refrigerant leaks.
By applying test solution to the area in question
with the swab that is attached to the bottle cap, bub-
bles will form within seconds if there is a leak.
For restricted access areas, such as sections of
the evaporator and condenser, an electronic leak
detector, such as
5-29547 or equivalent, is more prac-
tical for determining and locating leaks.

INDICATOR
2-HI-LOW SWITCH
4-BALANCE CONTROL
Figure 12 Electronic Leak Detector J-29547
ELECTRONIC LEAK TESTERS
(Figure 12)
Electronic leak testers can accurately determine
leaks in areas that are difficult to test with liquid leak
detectors due to poor visibility or inaccessibility.
The H-10 Leak Detector 5-26934 is a 110-volt,
A/C powered tester while the Refrigerant Leak Detec-
tor J-29547 is a portable, battery operated model.
Both models provide visual
and/or audible signals to
indicate leak detection.
The successful use of electronic leak detectors
depends upon carefully following the manufacturer's
instructions regarding calibration, operation and
maintenance. Battery condition is especially impor-
tant to the accuracy of the portable battery powered
model
5-29547 and is monitored by a low battery
indicator.
SERVICE PROCEDURES
Before attempting any service which requires
opening of refrigerant lines or components, the person
doing the work should be thoroughly familiar with the
information under HANDLING REFRIGERANT- 12,
HANDLING REFRIGERANT LINES AND FIT-
TINGS AND MAINTAINING CHEMICAL STA-
BILITY IN THE REFRIGERATION SYSTEM. Very
carefully follow the DISCHARGING, ADDING OIL,
EVACUATING AND CHARGING PROCEDURES
FOR
A/C SYSTEMS instructions given on the fol-
lowing pages for the unit being serviced.
Sealing caps should be removed from sub-
assemblies just prior to making connections for final
assembly. Use a small amount of clean 525 viscosity
refrigerant oil on all tube and hose joints. Always use
new O-rings dipped in the clean 525 viscosity refrig-
erant oil when assembling joints. The oil will aid in
assembly and help provide a leak-proof joint. When
tightening joints, use a second wrench to hold station-
ary part of connection so that
a solid feel can be
attained. This will indicate proper assembly.
Tighten all tubing connections as shown in
torque chart (Figure
13). Insufficient or excessive
torque when tightening can result in loose joints or
deformed joint parts. Either condition can result in
refrigerant leakage.
O-RING REPWCEMENT
Install new G. M. approved service replacement
air conditioning
"0" rings whenever a joint or fitting
is disassembled, except when provided on new com-
ponents. Even though an
"0" ring may look the same,
it is extremely important that only recommended ser-
vice replacement air conditioning
"0" rings be used or
excessive leakage of Refrigerant 12 may occur.

Removal
1. Remove oil pan as previously outlined.
2. Remove pump to rear main bearing cap bolt and
remove pump and extension shaft.
Disassembly
1. Remove
the pump cover attaching bolts and the
pump cover. Mark gear teeth so they may be
reassembled with the same teeth indexing.
2. Remove the idler gear and the drive gear and
shaft from the pump body.
3. Remove the pressure regulator valve retaining
pin pressure regulator spring and valve.
4. If the pickup screen and pipe assembly need
replacing, mount the pump in a soft-jawed vise
and extract pipe from pump cover. Do not disturb
the pickup screen on the pipe. This is serviced as
an assembly.
Cleaning and lnspection
1. Wash all parts in cleaning solvent and dry with
compressed air.
2. Inspect the pump body and cover for cracks or
excessive wear.
3. Inspect pump gears for damage or excessive wear.
The pump gears and body are not serviced
separately. If the pump gears or body are
damaged or worn, replacement of the entire oil
pump assembly is necessary.
4. Check the drive gear shaft for looseness in the
pump body.
5. Inspect inside of pump cover for wear that would
permit oil to leak past the ends of the gears.
6. Inspect the pickup screen and pipe assembly for
damage to screen or pipe.
7. Check the pressure regulator valve for fit.
Assembly
1. If the pickup screen and pipe assembly was
removed, it should be replaced with a new part.
Loss of press fit condition could result in an air
leak and loss of oil pressure. Mount the pump in
a soft-jawed vise, apply sealer to outside diameter of
swaged end of pipe, and using Tool
J-8369 tap
the pipe in place with a plastic hammer.
NOTICE: Be careful of twisting, shearing or
collapsing pipe while installing in pump.
2. Install the pressure regulator valve and related
parts.
3. Install the drive gear and shaft in the pump body.
4. Install the idler gear in the pump body in the
original orientation.
5. Install cover gasket.
6. Install the pump cover and torque attaching
screws to specifications.
7. Turn drive shaft by hand to check for smooth
operation.
Installation
1. Assemble pump and extension shaft with retainer
to rear main bearing cap, aligning top end of
hexagon extension shaft with hexagon socket
lower end of distributor drive gear.
2. Install pump to rear bearing cap bolt and torque
to specifications.
3. Install oil pan as previously outlined.
ROD CAP AND

Clearance
CONNECTING ROD BEARINGS
Connecting rod bearings are of the precision
insert type and do not utilize shims for adjustment. DO
NOT FILE RODS OR ROD CAPS. If clearances are
found to be excessive, a new bearing will be required.
Service bearings are available in standard size and
.013mm and .026mm undersize for use with new and
used standard size crankshafts.
lnspection and Replacement
1. With oil pan and oil pump removed, remove the
connecting rod cap and bearing.
2. Inspect the bearing for evidence of wear or
damage. (Bearings showing the above should not
be reinstalled.)
3. Wipe both upper and lower bearing shells and
crankpin clean of oil.

V-8 ENGINE 6A3-27
3. When finish honing
a cylinder bore to fit a piston,
the hone should be moved up and down at a
sufficient speed to obtain very fine uniform
surface finish marks in a cross-hatch pattern of
approximately
45" to 65" included angle. The
finish marks should be clean but not sharp, free
from imbedded particles and torn or folded
metal.
4. Permanently mark
the piston for the cylinder to
which it has been fitted and proceed to hone
cylinders and fit the remaining pistons.
NOTICE: Handle the pistons with care and do not
attempt to force them through the cylinder until
the cylinder has been honed to correct size as this
type piston can be distorted through careless
handling.
5. Thoroughly
clean the bores with hot water and
detergent. Scrub well with a stiff bristle brush and
rinse thoroughly with hot water. It is extremely
essential that a good cleaning operation be
performed. If any of the abrasive material is
allowed to remain in the cylinder bores, it will
rapidly wear the new rings and cylinder bores in
addition to the bearings lubricated by the
contaminated oil, the bores should be swabbed
and then wiped with a clean dry cloth. Cylinder
should not be cleaned with kerosene or gasoline.
Clean the remainder of the cylinder block to
remove the excess material spread during the
honing operation.
Piston Selection
1. Check USED piston to cylinder bore clearance as
follows:
a. Measure
the "Cylinder Bore Diameter"
with a telescope gage
"2-1/2" (64mm) from
top of cylinder bore").
b. Measure
the
"Piston Diameter" (at skirt
across center line of piston pin).
c. Subtract
piston diameter from cylinder bore
diameter to determine "Piston to Bore
Clearance".
d. Determine if piston to bore clearance is in
the acceptable range.
2. If
used piston is not acceptable, check Piston Size
Chart and determine if a new piston can be
selected to fit cylinder bore within the acceptable
range.
3. If
cylinder bore must be reconditioned, measure
new piston diameter (across center line of piston
pin) then hone cylinder bore to correct clearance
(preferable range).
4. Mark the piston to identify the cylinder for which
it was fitted.
OIL FILTER BYPASS VALVE
Inspection and Replacement
With the oil filter removed, check the spring and
fibre valve for operation. Inspect for a cracked or
broken valve. If replacement is necessary, the oil filter
adapter and bypass valve assembly must be replaced as an
assembly. Clean valve chamber in cylinder block
thoroughly. Torque retaining screws to specifications.
