Hello Guys!
I live in western Washington state and just got a new 160 engine to replace the old briggs on the mower. The deck is fine and the new Honda looks like a nice fit.
My question is, what kind of an adapter will I need for the 7/8" keyed shaft...and more importantly, it looks like I'll need to drill deeper and tap the hole for a bolt. What size tap should I use.
(Probably will depend on the kind of adapter kit I might get, right?) Any rectummendations would be appreciated! Thanks!

Most are 3/8-24 2B tapped but really need to know exactly which GCV160 you got to double check the specs.

Do not drill crankshaft, click on above for adapter plate, blade & bolts which are metric.
What brand mower deck do you have?

This why I said I need the exact GCV160 the op has [type code and probably it serial number] as there are a few threaded internally @ M10-1.25 and even some that are externally thread @ M14-1.5.

This is not a guessing game when it comes to using the right tap as the OP can really mess up the crankshaft if not done right.

I hope this helps: 4.4 HP 160cc Honda Vertical Shaft Engine GCV160 28-1931
Bought it through Surplus Center in Nebraska. I can post the engine or serial number if that helps.
Thanks, Guys!

GCV160LA0 - N5B

Now that clears things up as it not even tapped in the first place. Just a centering point for the lathe.

Mark I curious what keeps everything on the PTO shaft if it is not bolted on?
