Here I have a tool made for the Bsa/Triumph singles that have the oil fed end crankshaft,eg B44,B25,C15G,B40G, Triumph T25. This tool will pull the crankshaft into the main bearing nice and squarely.The crankshaft on these models are a tight fit into the main bearing some people try and press the crank into the bearing and damage the crankcase, seen it a few times ! A small price to pay so no damage is done. The crank and casing are not included. Overseas p/p is a estimate ,please ask first. Colours may vary .
