Subject: Spare Tire Lock Corrosion
Model and Year: 1963 Corvettes
Source: Chevrolet Technical Service Bulletin
Number: DR #610, Section X
Date: July 22, 1963
TO: ALL CHEVROLET DEALERS
Spare tire lock jamming or difficult operation may be due to an accumulation of dirt or salt deposits in the lock cylinder. The exposed location of the spare tire lock makes it susceptible to corrosion and subsequent malfunction.
To prevent or correct field complaints concerning this problem, the lock should be checked when the vehicle is in for service and if defective, cleaned, and a protective boot installed as shown on Page 2 of this bulletin.
Beginning with March 15, 1963 production, the protective boot Part No. 3841701 will be installed to prevent corroding of the lock.
