1745 Timken bearing simulator tool

When you are building a high-performance Big Twin engine from the 1970 to 2002 era, checking your clearances is non-negotiable. This Jims Timken bearing simulator tool is an ingenious addition to the workshop, allowing you to easily remove and replace the flywheel assembly in the left crankcase. It is perfect for checking rod-to-case, piston-to-flywheel, and cylinder-to-flywheel clearances without the friction and hassle of a press-fit bearing. By using this simulator, you can mock up your assembly multiple times to ensure everything is perfect before the final press, preventing costly mistakes and ensuring a long-lasting, reliable engine build.
