Hi,
I recently acquired a Gravely 816 with an Onan CCKA engine. The person who gave it to me said that over 10 years ago it stopped moving forward and reverse. He took it to an authorized Gravely dealer in our area and was told that it was the "internal forward/reverse clutch," and the charge would have been $1100, so he abandoned it.
The engine is shot from sitting outside for 10 years, but if the diagnosis by the dealer was correct, then what is the internal forward/reverse clutch? Is it actually gears inside the transmission, or is it the clutches bolted to the outside of the tranny? I really do not want to open the transmission up if I do not have to. Any ideas are most appreciated.
Thanks

HerbertK1,:MTF_wel:. Not sure to what the dealer was talking about.The only internal clutch I know of is the pto clutch. The dealer may have been talking about some other part in the trans and mistakenly called it a clutch.

I'm sure someone will be along to clarify your problem and let you know how to fix it. Good Luck!!!!!!!

Hi,
I hope someone has some insight. I'd hate to open up the transmission if nothing is wrong with the inside. I've never done that before, and don't wanna start now.

Without a running engine, it will be difficult to check out the tranny, but you can download the 800 series manual and IPL from www.oldgravelys.net to familiarize yourself with the components.

There is no internal forward/reverse clutch on an 816. Only one inside is the PTO clutch. To check without a running engine, place the tractor in one of the gears and High or Low range. Pushing it should show both clutches turning. Attempting to place in Forward or Reverse should cause the tractor to not roll or the engine to try to turn. It is possible that a key is sheared on the clutch hubs, but that doesn't cost a grand to fix.

Too bad it sat outside for ten years. Now, what could have been a simple repair will be a major project.

Thanks everyone. It is a mystery for now. I called the dealer, who diagnosed it (10 years) ago. The guy on the phone said..."those don't have internal forward / reverse clutches". So, now my focus is seeing if I can get the engine running to see what is actually going on. Not sure if that will be possible though.
