Aftermarket reduction case gasket for Honda GX-series kart engines with a reduction (wet clutch) case. Seals the reduction cover to the crankcase and replaces Honda part 21591-ZH8-620. Sold in packs of 5.
This version has a black rubber seal ring bonded around the shaft opening, so you get a better seal at the bore than a plain paper gasket.
- Fits: Honda GX120, GX160, GX200, GX240 and GX270 with reduction case
- OEM reference: 21591-ZH8-620 / 21591ZH8620
- Pack size: 5 gaskets
- Bolt holes: 5
Fit a new gasket every time the reduction cover comes off. A reused gasket is the usual cause of oil weeping from the reduction case on hire karts.
