Products Description
Outstanding High - Temperature Resistance
Crankshaft Seal for Honda GX340/GX390 & Clone Engines
Designed to seal both magneto and PTO shaft ends, this 35x52x8 seal prevents lubricant migration, maintains crankcase pressure, and shields bearings from debris. Manufactured from fluorocarbon elastomer (FKM) for superior performance in extreme thermal environments.
Technical Profiles & Materials
Exceptional Thermal Stability – Fluorocarbon (FKM/Viton) compound endures sustained exposure up to 200°C, far exceeding standard NBR seals. Retains elasticity and sealing force through repeated heat cycles.
Twin-Position Versatility – Engineered for both magneto/flywheel and output shaft positions. Simplifies inventory with one part covering two critical sealing points.
Precision Lip Geometry – Single-lip design with garter spring maintains constant radial load on the crankshaft. Steel casing prevents distortion during press-fit installation.

FAQ
Q: How do I verify compatibility before ordering?
A:Confirm engine model code from nameplate. GX340, GX390, or GCV530 class. If replacing a clone engine, measure shaft diameter (35mm) and housing bore (52mm). OEM numbers 91201-ZE3-004 or 91201-Z7E-003 confirm fitment.
Q: What failures cause premature seal wear?
A: Crankshaft surface scoring or nicks (use repair sleeve if grooved). Crankcase pressure buildup from blocked breather. Excessive bearing play allowing shaft movement. Misaligned belts or chains over-tensioning the shaft. Poor-quality replacement seals with incorrect compound.
Q: Any installation tips for maximum service life?
A: Always clean shaft and bore with solvent before installation. Lightly oil the lip and shaft. Drive seal flush with housing face using a flat driver-never deeper. Inspect shaft for burrs. Replace both magneto and PTO seals simultaneously during engine overhaul. Allow seal to settle one hour before first start.
