ENGINE AND ENGINE REBUILDING
PISTONS AND CONNECTING ROD | REMOVAL
(See Figure 47)
- Remove the engine assembly from the car; see Engine Removal and Installation, earlier in this section.
- Remove the intake manifold, cylinder head or heads, as applicable.
- Remove the oil pan.
- Remove the oil pump assembly.
- Stamp the cylinder number on the machined surfaces of the bolt bosses of the connecting rod and cap for identification when reinstalling.
If the pistons are to be removed the connecting rod, mark the cylinder number on the piston with a silver pencil or quick drying paint for proper cylinder identification and cap to rod location.
The 4-151 engine is numbered 1-4 from front to back; the V6-173 is numbered 1-3-5 on the right bank, 2-4-6 on the left bank.
- Examine the cylinder bore above the ring travel. If a ridge exists, remove the ridge with a ridge reamer before attempting to remove the piston and rod assembly.
- Remove the rod bearing cap and bearing.
- Install a guide hose over threads of rod bolts. This is to prevent damage to bearing journal and rod bolt threads.
- Remove the rod and piston assembly through the top of the cylinder bore.
- Remove any other rod and piston assemblies in the same manner.
CLEANING AND INSPECTION
Wash connecting rods in cleaning solvent and dry with compressed air. Check for twisted or bent rods and inspect for nicks or cracks. Replace connecting rods that are damaged.
Clean varnish from piston skirts and pins with a cleaning solvent. DO NOT WIRE BRUSH ANY PART OF THE PISTON. Clean the ring grooves with a groove cleaner and make sure oil ring holes and slots are clean.
Inspect the piston for cracked ring lands, skirts or pin bosses, wavy or worn ring lands, scuffed or damaged skirts, eroded areas at top of the piston. Replace pistons that are damaged or show signs of excessive wear.
Inspect the grooves for nicks or burrs that might cause the rings to hang up.
Measure piston skirt (across center line of piston pin) and check piston clearance.
WHEEL CYLINDERS | REMOVAL AND INSTALLATION
(See Figures 22, 22a and 23)
- Loosen the wheel lug nuts, raise and support the car, and remove the wheel. Remove the drum and brake shoes. Leave the hub and wheel bearing assembly in place.
- Remove any dirt from around the brake line fitting. Disconnect the brake line.
- Remove the wheel cylinder retainer by using two awls or punches with a tip diameter of 1/8 in. or less. Insert the awls or punches into the access slots between the wheel cylinder pilot and retainer locking tabs.
Bend both tabs away simultaneously. Remove the wheel cylinder from the backing plate.
- Position the wheel cylinder against the backing plate and hold it in place with a wooden block between the wheel cylinder and the hub and bearing assembly.
- Install a new retainer over the wheel cylinder abutment on the rear of the backing plate by pressing it into place with a 1 1/8 in. 12-point socket and an extension.
- Install a new bleeder screw into the wheel cylinder. Install the brake line and tighten to 10-15 ft. lbs. (13-20 Nm).
- The rest of installation is the reverse of removal. After the drum is installed, bleed the brakes using the procedure outlined earlier in this chapter.
