1. Engine Selection

Match the engine’s performance and cost to your specific application to get the optimum performance at an affordable price. That means better value for you.

2. Engine Installation

It is important to maintain the original engine’s size, starter type and position, fuel tank location, fuel line routing, muffler location, exhaust direction and muffler accessories (i.e., deflector, spark arrester, etc.). Reinstall all guards, shields and safety devices. Replace missing, worn or damaged parts

3. Crankshaft Specs

Compare the overall engine size to avoid possible mounting interference

  • Match the crankshaft
  1. A - Diameter
  2. B - Height (distance from base to crankshaft center line)
  3. C - Length (distance from oil seal/cover’s mounting face to end of crankshaft)
  • Match the crankshaft type, i.e., keyway, tapered or threaded
  • Match the crankcase cover’s tapped holes for mounting accessories (if applicable)
  • Match the base mounting dimensions and bolt hole spacing
