What is the 394498 flywheel?
The 394498 is a flywheel assembly for a piston air compressor: the large steel disc carries the V-belt / starter gear ring around its rim, machined ventilation slots between the hub and rim dump the heat that pumping builds up, and the central ball bearing in the hub carries it on the crankshaft nose. This one arrived new in its factory bag, handled only at the rim. The intake record lists it at 880 元, photos uploaded 3 July 2025 — no brand is stated on the record or the part, so match it by the dimensions and tooth count against your compressor's parts book. It passed through the Koeed warehouse on 3 July 2025; the photos below show it as received.

Fitting notes
Slide it on the crankshaft taper or keyed straight bore (match yours before ordering — both styles exist in this size), torque the retaining bolt to the manual's figure, and spin it by hand to hear the bearing run before the belts go on. A flywheel that wobbles at the rim will eat belts and hammer the crank bearing; check runout with a dial gauge against the rim while it is still on the bench.
