Kaiser Qwik Kit Uses Three Principles to Achieve Longer Life

1. Steel bushing. Steel pin combination for wearability.

2. Grease grooving on pins and bushings to provide more grease and better lubrication in high wear areas.

3. Seals to keep the grease in and the dirt out.

Tested 500,000 Miles Without Repairs

The Kaiser spiral steel bushing and pin used in front spring suspensions has nearly the same established wear life of 500,000 miles as that of the steering knuckle king pin and bushing. (See Bulletin 7.) Kaiser spiral steel bushings have proven to better withstand the wear action placed upon the front spring under all road and environmental conditions.

Steel's Proven Performance

The Spring bushing is made of 12% Chrome, 1.5% Carbon tool steel, and heat treated for strength and durability. The Kaiser Spring Pin is made from an alloy steel (8620), carburized and hardened to a hard case of 62/64 R/C scale. A tough ductile core is left to take up shocks transmitted through the spring action. Highway tests have proven the two steels to be compatible without galling or seizing.

Front Spring Qwik Kits

Kaiser Qwikkits for front spring eyes and shackles are manufactured for most springs used on axles with ratings from 1,500 lbs. to 22,000 lbs. There are also some applications for the rear springs. (See Kaiser Cross Reference Catalog #101.) All Qwik kits come with 2 bushing assemblies, 2 pins, and necessary hardware. The bushing assembly is made

up of a carburized and hardened steel sleeve and a Kaiser spiral steel bushing. The steel sleeve protects the Kaiser spiral steel bushing from grit and dirt and tends to make the forged spring eye round to accept the pin. By sizing the bushing assembly in manufacturing, NO reaming is necessary during installation. Pins are finished ground to a running clearance fit of 4 to 6 thousandths. (.004 to .006). Work can be done with the spring on the vehicle to save installation labor cost by eliminating spring removal and reaming operations.

Savings from Minimum Tear Down

Both time and effort can be saved by working one side of the spring at a time, either front or rear. Repairs can be made in about one-half the time by using this procedure. Drop the end that needs repairing, and drive out the old bushing. Spring eyes must be clean of scale and rust before installing the Kaiser bushing (continued)
