Shock re-build process
Lever action type shock absorbers were used on most cars until early 1950s and on some sports cars as late as 1980s (MGB, for example). Pistons in these shocks are connected to a shaft, one end of an arm (or a pair of arms) is attached to the shaft and the other end is connected to the suspension spring. Spring oscil- lation causes back and forth movement of the arm, which on its other end induces rotary movement of the shaft, causing pistons to move and force the fluid through the valve ..., and spring oscil- lation is dampened. (Compare to modern “direct action” tubular shocks where piston and spring are attached to a single rod.)
Always check shock absorbers!
INOPERATIVE OR WORN OUT SHOCK ABSORBERS CAN CAUSE UNDUE TIRE WEAR, HARD STEERING, LOSS OF CAR CONTROL, SHORT BRAKE LIFE, AND PREMATURE FRONT-END WEAR.
Two levels of shock rebuilding services:
STANDARD
Apple Hydraulics long standing reputation for precision workmanship started with these fine rebuilt shock absorbers. Externally cleaned to bare metal. Housings rebushed with
bronze bushings, shafts reground and polished. Cylinders and pistons are align honed and polished. To aid dirt and water exclusion highest quality double-lip seals are used, which outlast originals. Valving is properly calibrated for correct jounce and rebound specs. Painted with a gun-metal gray primer.
All rebuilt shocks come filled with fluid and ready for instal- lation on the car.
Prices listed in this catalog are for Standard Rebuild.
HEAVY DUTY
Ever since introduction of our Heavy Duty shock line we have been selling them 2 to 1 over standard units.
Designed for our customers who enjoy driving their cars with performance in mind. Rebuilt to same high quality as our standard units, but with larger bronze bushing where main shaft rides. Shock valving is upgraded, 15% stiffer than standard shock, but a longer lasting unit. Highly recom- mended for many Armstrong aluminum body shocks, esp. Big Healey front, Midget/Sprite front and TR-6 rear shocks, and also for Delco double arm front shocks.
Please add $10 per shock for Heavy Duty Rebuild.
