James Gaskets Derby Cover Gaskets/seals

13 products — part of all Derby Cover Gaskets/seals

James Gaskets derby cover gaskets and seals give Harley-Davidson Big Twin owners the precision-cut primary cover seals needed to prevent oil leaks from the derby plate inspection cover on the outer primary chaincase. The derby cover is removed every time the primary oil is changed or the clutch is inspected — a routine that on a well-used Harley-Davidson happens several times a year, and each removal stresses the existing gasket. James Gaskets produce their derby cover gaskets to exact Harley-Davidson specifications, with material choices that compress correctly under the specified cover bolt torque and resist the primary chaincase oil that keeps the clutch pack lubricated. A fresh James Gaskets derby cover seal on every reinstallation is the surest way to prevent the primary oil seep that stains the frame, the chain and the ground wherever the bike is parked. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries James Gaskets derby cover gaskets alongside a comprehensive primary covers and sealing range.
