Key Features

• OEM-Grade Seal Material — Manufactured to the same elastomer compound and compression rating as the original, ensuring full contact and a consistent sealing surface against the rear shaft journal.
• Direct Replacement for DCA150SSJU — Engineered specifically for the DCA150SSJU ultra-silent diesel generator; installs into the existing seal bore without modification to the housing or shaft.
• Leak-Free Engine Rear End — A properly seated rear oil seal prevents crankcase oil from escaping past the rear shaft, protecting bearings and keeping the generator running cleanly at rated load.
• Prevents Contamination and Oil Loss — A worn or failed rear seal allows oil to migrate into surrounding components, leading to oil starvation, premature bearing wear, and potential alternator damage on long-run generator sets.
• Genuine OEM Part — this part is an authentic Multiquip component, ensuring the seal profile, lip geometry, and material grade match what the engine was originally built with.

A rear oil seal sits at the back of the engine crankshaft, creating a dynamic lip seal between the rotating shaft and the stationary engine block or housing. Its job is to retain engine oil inside the crankcase while keeping dirt and moisture from entering. When a rear oil seal degrades — through heat cycling, age, or mechanical wear — it begins to weep or leak oil, which can coat nearby components, create fire risk near exhaust surfaces, and cause the engine to lose oil pressure over time. Replacing a failed rear seal promptly with the correct part restores a clean, tight barrier and protects the engine's long-term reliability.
