Clinton A400 vs. A490

Post by Timothy Klatte » Thu May 23, 2019 5:36 pm

Are any parts interchangeable between the A400 and the A490?
Thanks for any info.

- The blocks are different -there is a pocket for the PTO ball bearing on the A490
- Cranks are different - ball bearing press fits on the crank
- Pistons, rods, rings, gaskets, manifold, carb, tank and pretty much everything else is the same for the two
