Hi. I'd like to install a billet flywheel onto my EX-17 Robin. However, the vendors I've contacted don't have aftermarket 'wheels for it. No one knows if the Honda/clone flywheel will fit any Robin engines.
If someone out there can post specifications on Hondas or clones, I can compare them with Robin engine flywheel measurements.
The Robin EX-17 engine flywheel
1-piece mounting plate and fins;
2.36" thick, including fins;
7 lbs. in weight;
7.0625" in diameter;
keyway is .125" wide;
The Robin engine's crankshaft is tapered;
Its machined nose is 1.125" long;
Total length of shaft with threaded tip is 1.93" long;
At its base, the machined shaft is .97" diameter;
At the nose of this machined surface, it is .79" in diameter;
The shaft's half-moon key is .11" wide.
Thanks for any information you can give.:thumbsup:
