Us Pro - Tools 7pc Diesel Engine Injector Seat Cutter, Cutting Tool Pilot Key 5588

Set of 5 cutters for re-cutting injector seats when reconditioning diesel engines or replacing the injectors. Injectors can be extremely difficult to remove, due to the build up of carbon deposits and the effects of corrosion. Once they have been removed, the injector seat is often in a condition that makes it almost impossible to successfully seat the injector, and there can be a high risk of 'blow-by' (leaking of combustion gases from the cylinder, via the injector seat) occurring as a result. This can lead to various poor running and starting symptoms: excessive smoke, tar build-up, noise and loss of compression). The Injector Seat Cutter set allows the technician to re-face the seat, in order for the new or reconditioned injector to be fitted correctly. (it is recommended that re-facing of injector seats is done with the cylinder head removed to avoid the risk of metal filings entering the combustion chamber).
