961 Norton – Crank Removal Manual
Download the complete PDF version using the green download button at the top right of this page for a detailed Norton 961 crankshaft removal guide covering the final stages of engine strip-down, crank removal procedures, crank centre support inspection and important reassembly precautions for modern Norton 961 engines.
This illustrated workshop manual created by Richard Coote walks through the process of removing the crankshaft from a Norton 961 engine once the motor has already been stripped to the required stage. It includes clear full-color photographs showing crank access, baffle removal, crankshaft extraction, O-ring locations and the internal crankcase areas that must be checked carefully during disassembly.
The guide also highlights a potentially serious crank centre support issue seen on some 2013–2015 engines, where the support bolt may torque up without the mounting face sitting fully against the crankcase. Detailed photographs explain what to look for, how the interference issue may appear and the corrective drilling procedure described for confident, experienced mechanics.
Important cautions are included throughout covering protection of bearings and oil passages, preventing swarf contamination, using new O-rings during reassembly and confirming all oil passages are clear before final assembly.
