Abstract
Abstract A spacer system for a differential lock assembly having a fixed clutch and a sliding clutch with a sliding-clutch collar. The spacer system comprises a shift fork member and a bearing adjuster which contact when the sliding clutch and fixed clutch are engaged so as to prevent the shift fork member from binding within the sliding-clutch collar, without requiring a manual adjustment to account for tolerance stackups or gear or bearing positional adjustments.
