Short Description: Ensure the longevity of your crankshaft with this high-precision oil seal. Essential for preventing oil leaks and protecting the front main bearing from contaminants, restoring the airtight integrity of your engine.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible models)
• Manufacturer Code / SKU: MT801190
• Part Type: Engine / Crank Gear (Sealing)

Purpose and Role in the Motorcycle (based on the original manual):
The MT801190 Gland is a critical sealing component installed at the front end of the engine crankcase, specifically designed to work in tandem with the 209 Single-row radial ball bearing (the crankshaft front bearing). Its primary function is to maintain a secure, airtight seal around the crankshaft journal, preventing the engine's lubrication oil from leaking out and, more importantly, excluding the ingress of dust, moisture, and debris into the bearing race. According to the technical manual, failure of the gland seals can lead to a dangerous increase in internal crankcase pressure, which not only causes oil leaks but also triggers premature oil contamination and accelerated wear of the crankshaft and connecting-rod components. You should replace this gland if you notice oil seepage at the front of the engine or during any crankshaft-related overhaul.

Benefits of Buying:

• Exact Technical Fit: Manufactured to the precise dimensions required for the 209 ball bearing and MT-11 crankcase, ensuring a leak-free installation.
• Enhanced Engine Protection: By keeping contaminants out of the front main bearing, you significantly extend the service life of your crankshaft and reduce the risk of unexpected engine failure.
• Restored Oil Integrity: Eliminates oil weeping at the front journal, helping you maintain the strict oil consumption limits specified in the MT-11 technical manual.
