About this part
The crankcase on your Bonneville T100 T100 carries the crankshaft and main bearings and holds the engine oil. Cracks after a con-rod failure, worn bearing seats or stripped threads usually leave a replacement casing as the only fix.
Frequently asked questions
What should I check when buying a crankcase for the Triumph Bonneville T100?
Match the engine code and casing number of your Bonneville T100 T100, as manufacturers revise the part several times within one series. On motorcycles the case halves are machined as a pair at the factory, so always buy them matched.
What deserves extra attention when buying used?
Ask for photos of the bearing seats, sealing faces and threads, plus mileage and the reason for removal. Hairline cracks near the oil galleries are the usual reason a cheap crankcase turns expensive.
