kawasaki fc420v 14hp.

I have an exmark m-48-14k-5 with a Kawasaki fc420v engine. its preety old from around 95 or so. Compression was on the low side it was 74psi. So I took motor apart and thats were problems began.

Maybe motor was bebuilt in the past not sure. Strange thing is that it seems that the piston, connecting rod, and pin are not spec for the fc420v.

I purchased piston rings 13008-6001 but these rings are to thick for my piston. they are .078 and the rings I took out are .058.

Trying to find specs for piston rings or anything for Kawasaki is a pain in the butt. On bottom of piston its marked u-4. On side of piston is a number 4. on connecting rod it looks like a pacman symbol then -1-1

Anybody know what these numbers mean so I can get correct part.
Any info would be greatly appreciated. Thanks Scott

Scott,

Post the spec number off the engine next to the FC420V, Should look like FC420V-BS15 for example.......

The FC420 used 2 different piston and rod setups...
Find a spec # that uses a different piston and rod...and youve found your parts..

Scott....its easier than you think....
They only made 2 different piston and rod setups...
Look thru a few spec numbers till you find a different piston and rod setup ...bingo...
Its basically the older and the newer style setups...

Did you do any other tests on it? Wouldnt be tearing an engine apart just because it had 74psi of compression...
