Replacement jaws for the most popular version of the tool used to pull the crankshaft timing gear of Triumph and Norton big twins. The tool was originally supplied by MCE, and an improved version is also available in my store, if you need the whole tool.
These jaws are bi-angle ground to fit within the tight confines of the timing chest, and can wear out with multiple use or break if the timing gear isn't heated before extraction. So here are replacements if you need spares. They should fit any style of the puller tool noted, construction is 304 stainless steel.
