We do not have any of the Churchill fitting tools for the fitting of the injector sleeves. They are an expensive set of tools, so typically only garages who service a lot of Leyland engines would invest in the set of tools. Here at Tractor Spare Parts we have developed an injector sleeve of part number 37D2599 which can be fitted without these rolling tools. This injector sleeve is machined from a solid piece and has the O-ring integrated. It can be fitted to the BMC and Leyland cylinder heads without specialist tools. We offer a fitting instruction sheet.
