Tiger king 1.6 mm Full circle Crank No Taper
Tiger King 1.6 marine full circle crank.
By far the best crank we have ever seen.
Note: In Zenoah or RCMK bottom ends may require
the use of a crank shim--TK-B0005 or TK-B006
Changing to this crankshaft requires modifying the squish on your cylinder to accommodate the longer stroke. We recommend that the cylinder be modified, this is a far better solution than stacking gaskets to get the added clearance.
To install this crankshaft, a very small bit of crankcase material must be removed so the lower end of the connecting rod will not rub on the case. This is easy to do , and can be done with a Dremel tool.
The lower rod of the crankshaft (since it sits lower than the stock rod location) makes it slightly rub on the crankcase. Before using this crankshaft, it is essential that you remove a small amount of crankcase material to free up space so the rod does not hit. Once you do this, be certain you COMPLETELY clean the crankcase so it is free of any debris or shavings! Any small pieces of debris or metal left in your crankcase could damage your engine.
MAKE SURE YOU COVER YOUR BEARINGS WITH TAPE WHEN USING THE DREMEL TOOL, SO NO SHAVINGS GET IN YOUR BEARINGS. ALSO, COMPLETELY CLEAN THE CASE OF ANY SHAVINGS WHEN FINISHED!
Before running the engine, make 100% sure the crankshaft is not rubbing any part of the crankcase. Failure to do so will damage your engine.
The first version cranks with tapered ends fit with no problem. The latest crank crank with no taper has a much thicker rod. The big end has more material added around the outside and will touch the case on others brand cases
