This points seal installer for your Triumph motorcycle keeps from tearing your oil seal when installing your timing cover. You won’t know if you tore your seal until after you have reinstalled your points plate and timed the engine, if you have a leak oil will get past the seal and leak into the dry timing housing. This tool threads into the end of your cam before you fit your timing cover back on, and the taper helps easily guide your cover in place while protecting the oil seal. This tool is for Triumph and BSA motorcycles up top 1968 with BSF threads. This is a replacement for Triumph factory tool OEM # 61-7013.
