This article is re-issued for the following reasons:
^ Change the word "PINION" to "VALVE" in the title.
^ Change "large" to "small" diameter bore housing
- after part number E3SZ-3548-A in the text.
Beginning early in the 1983 production model year, a revised power steering rack and pinion gear housing with a smaller diameter valve bore will be used.
The only external difference between the new and previous gears is the lefters "SPR-BJ or BK" stamped on the upper right end of the rack housing of the new gear. Internally, the new gear uses smaller valve seals, but is otherwise the same.
Future seal kits will contain two sets of valve seals to accomodate both housings. The "red or blue" seals are used on the new, small diameter bore housing. The "white, tan or green" seals are used on the previous, larger diameter bore housing. Following is a method for choosing which set of service seals to use based on color.
