Detroit Diesel 53 Series Rear Crankshaft Wear Sleeve | 23516636 | FP Diesel

FP Diesel rear crankshaft wear sleeve for Detroit Diesel Series 53 engines, replacing Detroit Diesel 23516636. The sleeve presses over a worn crankshaft seal surface to provide a new sealing diameter, avoiding crankshaft replacement or machining. Requires an oversized rear crankshaft seal — a standard seal will not work with a wear sleeve fitted.

Compatibility & Fitment

Required companion part — a wear sleeve increases the sealing diameter, so an oversized rear crankshaft seal must be used with it. Detroit Diesel 5196852 is the single-lip oversized seal specified for use with this sleeve. Ordering a standard-size seal will result in a leak.

Fitment gate — confirm your crankshaft has not already had a wear sleeve fitted. A second sleeve cannot be installed over an existing one, and a crankshaft that has been sleeved previously needs the old sleeve removed first.

Installation note — the sealing surface must be clean and the sleeve pressed on square to its correct depth. Check the crankshaft flange for damage beyond the seal track before fitting, since a wear sleeve corrects a grooved seal surface but not a damaged or out-of-round flange.

Conclusion

This is the FP Diesel rear crankshaft wear sleeve for Detroit Diesel Series 53 engines, replacing Detroit Diesel 23516636. It restores a worn seal surface without replacing the crankshaft. Order an oversized rear crankshaft seal with it, since a standard seal will not seal against a sleeved crank.
