The Perkins 4107 and 4108 diesel engines have a chronic problem with leaking rear crankshaft seals. Perkins owners replace them frequently to no avail. They just continue to leak. . Even new genuine Perkins replacement rear seals leak after a few hours of use. This is especially problematic and expensive in a marine application where there is limited access to the engine. But Foley Engines has a solution to this chronic problem. A solution that is a permanent fix.
Foley Engines has developed a new and improved rear crankshaft seal kit. No longer are you subject to having a rope as a seal for your marine or industrial Perkins 4.108, 4.107, or 4.154. Foley’s Hytork Rear Seal Kit is made from special Teflon coated nylon braided material and has been proven over & over again to stop the chronic rear seal leaks on the engines.
