This kit is specifically engineered for the Perkins diesel engine found in the 390 , which has earned a reputation for durability and fuel efficiency when properly maintained. Made to Last Every component in this kit is manufactured to meet or exceed original equipment specifications. The complete kit includes sleeves and sleeve seals, pistons and rings, pins and retainers, pin bushings, complete gasket set, crankshaft seals, intake and exhaust valves, springs, guides, and valve keys .

Installation Notes This is a complete rebuild job that requires proper machine shop work including boring, honing, and valve work. Take your time with assembly and follow proper torque specifications throughout. A good tip is to keep everything organized as you disassemble - label bearing caps, mark piston positions, and bag hardware by system. This attention to detail during teardown makes reassembly much smoother and helps ensure everything goes back where it belongs.
