COMPONENT CODES 4251, 4256SUBJECT: 3V-0197 BOLTS MAY NOT HAVE THE PROPER HEAT TREATMENT
PROBLEM:
The front brake supplier was using a bolt similar to 3V-0197 Bolt, which did not have the required heat treatment on the tip of the bolt. When the bolt is tightened, the end of the bolt can flatten and cause the bolt to loosen.
SOLUTION:
Illustration 1. (A) Bolt without proper heat treatment
(1) 3V-0197 Bolt with proper heat treatment
Check 3V-0197 Bolts. Bolts that are not properly heat-treated are silver in color and have a picto of a nut and bolt on the head of bolt (A). Properly heated bolts are black in color and have a plain head (1).
Ensure that all 3V-0197 Bolts have the proper heat treatment.
