Haha, it seems it has struck again.

As I mentioned in the, "What did you do with your Gravely," thread, I got a lead on a CCKA powered 816 earlier this week. Today I made a short 500 mile round trip to go pick it up. The guy i got it from picked it up in the early summer, but found he was never going to get around to working on it. he mainly was looking for a trade, not cash. He's a collector of all tractors, no matter the brand or features. I offered him my 75' 810 and he liked that so we struck a deal.

It's in fairly good shape overall. The Onan runs, I heard it and saw it running today, and it has all the normal 816 features including rear liftable hitch, snow plow latches, and PTO axle block. It also has the very rare Gravely individual steering wheels, not be confused with individual rear wheel brakes, ;). Obviously it needs a little work. The steering arm on the bottom of the sector box is missing its key and the wheel just spins; the reverse clutch has worn out splines, (the forward was well greased but not the rev,); there's an oil leak somewhere on the left side of the engine, as you can see the rear hitch and left axle is coated in it; the rear hitch is missing the lift rod that connects to the rocker shaft; the fuel tank collected water and is coated in rust on the inside; and the hydrualics leak down, which may be where the leak is. Overall though I'm happy. I only paid $150 for the 810, and it actually came from about 20 minutes up the road from where I got this 816. The serial looks to put the tractor as a 74'

Nice grab!
You may be right that the leak is coming from around the hydraulic pump, check the hard lines for tightness or maybe the gasket is leaking. The reverse clutch is dirty too so it could be coming from the seal there.
The steering wheel will spin when the gear at the bottom of the wheel shaft disengages from the sector gear in the box so it may not be a missing key.

Double check all the fittings at the pump. Had one at work we had the tranny out of and put back and the fitting at the pump I didn't touch started leaking.

But at any rate nice haul (again) :thThumbsU

Thanks guys, ill check the fittings and the steering shaft and see what's up. At the moment the arm that comes off the bottom of the box can't be attached because that's where I'm missing a key. As you can see both wheels are pointed out wards at the moment because of this.

The bona fide 816 models are pretty sweet. Now you get to compare the original CCKA-powered version to your 816T.

Quite a list of maladies there Rick but your the right guy to figure them out. I wonder if those reflectors on the back are original? Can anyone shed any light on that?

Thanks! I agree, I can totally see why they were one of the most important models in Gravelys entire line. You really get a whole, and a pretty awesome looking tractor at that. There's just something about seeing that big ole' CCKA sitting there on the back end. It just gives the tractor an entirely different stance.

Thanks Al! I'm looking forward to it, with the steering in the condition that it is I may have to work on my R/P conversion quicker than I had planned. Not sure on the reflectors, ill have to take a closer look and see.

Got a chance to really look the tractor over tonight. I figured out why the steering wheel just spun. When the set screw on the output shaft of the sector box loosened up and the key fell out, the wheel was over turned completely in one direction. If you turn the wheel all the way in one direction with the steering arm disconnected then the gear gets dislodge from the shaft, which I'm assuming is the same thing that was mentioned earlier in this thread. Turning the output shaft and the wheel at the same time got the gears realigned. I replaced the key with a spare that I had, and now the steering works enough to be able to drive it. The box does have the usual amount of play, about 5" of the wheel turning to either side before it goes right or left. Are all of the sector boxes supposed to have grease zerks? The 810 I trade had it, it was a 75', and my 432 has one, but I can't seem to find one on this 816.

I had hoped to fire it up tonight. Got the terminals cleaned up and an IV tank going to the carb. As I was opening the valve on the tank, (I had already hooked up the battery about a minute prior,) I started smelling an electrical burning smell near the engine. I started checking the wires and noticed the bundle of wires going to the stator, and whatever else may be down behind the flywheel, was getting way too hot. Key wasn't even on, and the battery was just hooked up. Looks like ill have to look into the wiring before I can fire this thing up.

All in all though, glad I was able to get the steering fixed pretty easily.

Good luck with the 816. Once everything is sorted you'll enjoy it. I rewired mine from end to end last year and it was well worth the trouble. While I was at it I replaced regulator and relocated it to under the dash.

Thanks! Hope to get it going soon. I've had to completely rewire two tractors in the past and even though it's a pain, it's worth it in the long run. Did yours have the regulator behind the flywheel? I know some of them do. Mine has some thing that looks like a regulator mounted on the inside of the frame below the seat pan. Don't believe it's the regulator though.

I spent some time pulling the R/P retro fit kit from my 810 parts tractor. On one side the bolts came off fine, the other side required an angle grinder with a cut off wheel. After about 30 minutes I had it out; was even able to separate the steering wheel from the shaft. The shaft has seen better days. I'll go with it for now, but keep my eyes open for a replacement. This 810 sat in the woods for a while and the old battery completely disintegrated the frame. Worst shape I've ever seen a frame in. The weldment will need a little derusting and some paint, but the core pieces of it are in good shape. Now to find the rest of the parts that I removed 2 years ago and make a template. This 810 was my first rider, never had it running, but it's amazing the amount of stuff I've been able to pull off of it.

Don't know what you paid for the 810 but I'm guessing just the R&P kit made it worth the purchase. And you mentioned getting other parts off it, to boot.
I think I paid about $315 for it. That price included a running L with a snow plow, a 106 mower with a sheared horizontal shaft, and the 810 came with a complete 40" commercial mower running off of a front drive kit with lift assist. I think I made it all back after selling the L with the repaired 30" mower. From just that 810 I've been able to pull off and use: entire front drive kit and mower, front wheels and tires, hood, 1 rear hub, (can't get the other one off,) clutch studs, carb, fuel pump, grass catcher screen, hitch, and now the R/P retro fit kit. I think I've gotten my moneys worth from it...:dunno::fing32:

Had a little time to start jumping into the wiring issue. Interesting to find that the inside of the shielding was painted yellow. Perhaps the engines were painted a standard color by Onan at the factory before going to equipment OEMs? I pulled the flywheel and, "holy oil build up Batman." Though, any CCKA I've ever seen on this board has never been clean on initial inspection. After brushing and picking away some of the layers of dirt I found the wire connector going to the stator. One of the two yellow wires is corroded, almost broken off, and missing its insulation. I'd say that's probably the wiring problem. From what I can tell it looks like someone removed the original regulator behind the flywheel, based on the two wires in that 4 wire connector that were cut off. Its now located on the inside frame rail under the seat. My goal is to patch the wiring up enough to run and inspect all functions, PTO and such, before tearing deeper into it. I'll keep my eyes open for a good used exhaust, this one had already been welded on numerous time. Anyone know the PT# for the original one? Couldn't find it noted in any IPL.

From what I remember others telling me, that may have been the primer color from Onan. Here's a picture of one of the shroud pieces from my '73 816. You can see the yellow on the inside as well. It definitely has a different tinge from the yellow that Gravely used on the earlier Commercial series machines.

As I mentioned in the, "what did you do...," thread, I spent a little time getting the 816 going yesterday. Basically a carb clean and unhooking the stator and she ran. Here's a pic of the inside of the carb after cleaning it fairly well, and then a vid of start up and checking it over.

Thanks Guys! Most of the junk I was able to get out of the carb fairly easily. I think if I let it sit in something to loosen it then the rest should come right out. Worst comes to worst and I'll put a DD carb from a B on it. I already plan to change the points to a B series setup because they're pretty hard to get at, although I didn't have to open them to start it.

Steven, they're always watching us.....lol.
