FAQ

Q1: What is the difference between front crankshaft oil seal and rear crankshaft oil seal?

A1:
‑ Front Crankshaft Oil Seal: Smaller dimension, located at timing gear / pulley side; relatively easy to replace; mainly prevents oil leak towards drive belt.
‑ Rear Crankshaft Oil Seal: Larger‑size heavy‑duty seal, fitted at flywheel end; replacement requires removing gearbox and clutch assembly; leak will contaminate clutch components.
These two seals have different inner‑outer diameters, housing sizes and lip structures and cannot be interchanged.

Q2: Which truck engine models do your crankshaft oil seals fit?

A2: We provide matched front and rear crankshaft oil seals for mainstream light‑duty diesel engines used on ISUZU, JMC, Qingling, JAC light trucks, covering engine models including 4JB1, 493, 4DA1. For other engine versions, please provide OE part number, engine model and old seal dimension (ID / OD / thickness) for accurate matching.

Q3: Are your crankshaft oil seals OEM‑equivalent replacement parts?

A3: Our crankshaft oil seals are manufactured according to OEM dimensional and tolerance standards. Each batch undergoes high‑temperature resistance, oil‑immersion swelling test and lip spring tension inspection before shipment, adapting to continuous heavy‑load working conditions of light‑duty diesel trucks.
