SERVICE INFORMATION

This bulletin provides information to correctly use the new wheel balance adapter kit. The kit is an essential tool for all Infiniti dealers.

Adapter Kit Hardware

1. Base Kit (for all dealers)
1-Spring
1-Cone (with insert installed for machines with 28, 30 and 36 mm shafts)
1-Flange plate (with insert installed for machines with 28, 30 and 36 mm shafts)
6-Flange plate studs

2. Adapter Kit with Replacement Shaft (for dealers with Coats. Sun 1742 & 1762, and Nortron balance machines with 28 mm shafts only, and Bear 8-200 with 30 mm shafts
1-Base Kit
1-Replacement shaft
1-Wing nut
1-Pressure cup

NOTE:
The replacement shaft is necessary for the above mentioned machines since the threaded portion of their spindle shaft is slightly smaller than the non-threaded part. This causes incorrect centering of the flange plate in the new adapter kit which results in measurement errors and eventually customer complaints.

The 28, 30 and 36 mm cone and flange plates have factory installed inserts to fit the spindle shaft on your balance machine. The inserts can be pressed out and fitted with new inserts (if necessary) to match other spindle shafts of various balance machines that are currently in the market. For further assistance, contact your TECH MATE program at 1-800-NMC-2001.

Check the Operating Condition of Your Balance Machine

Your balance machine must be calibrated and in good condition to achieve a correct wheel balance. You must perform the following procedure periodically and before using the new adapter kit.

1. Check the back plate and spindle shaft on the balance machine for excessive runout and wear. Contact your specific balance machine manufacturer for specifications. If the runout or diameter of the back plate or spindle shaft are out of specification, it will be impossible to correctly balance a tire/wheel assembly to within Nissan standards.

2. Locate the operation manual and calibrate the balance machine per the instructions.
