Date: September, 1983
Subject: PACKAGING CHANGE IN THE THREADLOCKING COMPOUND RECOMMENDED FOR TBI SERVICING - 1982-1983 ALL APPLICATIONS WITH TBI
TO: ALL CHEVROLET DEALERS
There are a variety of procedures involving TBI servicing where threadlocking materials have been found to be desirable. For these applications, Rochester Products has recommended the use of Loctite 262, or equivalent. Recently, the manufacturers of Loctite have changed the package labeling of their product Threadlocker 262, and this has caused some concern. Although the makeup of the compound has not been changed, the description "PERMANENT" and the term "Non Service Removable" has conveyed the impression that any parts, once coated with the compound, would be joined forever.
For the applications involving TBI screws, the diameter of the screws, the nature of the mating aluminum casting material into which they are driven, and the length of these screw thread engagements, are such that the use of Loctite 262 is satisfactory. Although there are situations involving the use of this high strength material that could be considered permanent, TBI screws which have been coated with the compound can be removed without damage, if necessary.
