On fixing a flat tire.... and a stubborn Ariens clutch lever

(Making progress, slow but sure. This thread started a few years ago. The clutch lever was replaced and works fine, but finally getting to the shift rod adjustment) Two questions.... I've got an old 7HP Ariens with the H70 engine, a tire was low (maybe empty) so I inflated it just before using it. Short while later I see it's riding off the rim. Inflated it again and made it through the storm. I did notice the second time around, with a now wet rim, that the air was leaking (bubbling) out through the base of the stem, and a tad around the bead. What's the right way of changing a tire tube on a rusty rim so it holds air? And about a clutch. The hand lever was all but locked and wouldn't go in. Although there may not be a relationship, I fiddled with the gear selector a bit and then the clutch worked fine. This happened several times. I looked inside the chassis and didn't see anything amiss, but at the time the lever was also working properly. What could cause an intermittent lockout of the clutch lever from functioning?

It's an old one. The model number is 10962, serial 005998. I see Googling that it's a late 1969 model and was able to download the manuals for it from Ariens thanks to leads at this site. Tire size is 12.5 x 450-6. The service manual shows tire 71046 and tube 71050 on assembly 155 610985. How does the tube come out of the tire? I tried prying the bead over the rim without success.... there must be an easier way. And I haven't seen this size tire for sale anywhere, chains yes, the tire itself no. The lever is on the left side under the handlebar and it releases/engages the wheel drive.

I see that design in the rim, and thanks for pointing out what should have been obvious. Is there an easy way to flatten the tire so the bead is in the center, perhaps "C" clamps? It's a stubborn material to flex.

The clutch lever via the linkage moves the internal drive bracket assembly. That assembly carries the friction disk. It moves the friction disk up to the drive plate which eventually caused the wheels to turn. When you let off the hand clutch the friction disk backs off the drive plate. That is, the drive bracket gets pulled back by a spring to it’s home position. It seems you have some binding in the drive bracket or the movements at the base of the linkage rod where it goes into the tractor housing. Moving the shifter will cause movement in the hex shaft and friction disk which are connected to the drive bracket. Moving the shifter probably causes enough movement in the drive bracket to free up what ever is binding it. That could be the drive bracket or the linkage at the tractor base. It could be worn parts, rust or lack of lub causing the disk bracket to be tough to move. Things to check: - Linkage where it enters the tractor base, lubricate..
- Put the machine on it’s bucket and watch the drive bracket move when you engage the clutch. Lube the pivot points, look for wear.

When you let off the hand clutch the friction disk backs off the drive plate. That is, the drive bracket gets pulled back by a spring to it’s home position. This one must be an antique because engaging the lever stops the machine. I've cleaned and lubricated everything but it still sometimes binds. Watching it, appears that everything should be fine but it's not. I can live with it and hope it works out the kink. I got the tube into the crazed and cracked tire with the aid of some dishwasher soap. No way that aged tire was going to come off one side of the rim without self destructing. Gonna adjust the length of the shifting rod at the threaded knob/locknut adjustment that's just outside of the tractor. The machine doesn't readily engage in reverse, and sometimes in neutral will creep forward as if it's in first. And fourth seems to travel really fast, I'm almost trotting along behind it. I want to lengthen the rod (is that correct logic?) but by how many turns? I don't want to be too aggressive and break anything.

I've been basking that seized adjustment fitting with PB spray for days now. The nut is free, but the threaded shaft part is seized up really bad. Tried some heat from a propane torch today; figured nothing to lose. Started with a gentle tool and last attempt was with 16" pipe wrenches. I don't think I can fabricate a part like that. The local dealer said he has used parts like that but doesn't sell them over the counter, and I'd resent paying someone to install it for that reason. So for now I just toodle along in 3rd and try avoiding needing reverse or neutral. The old rusty heap works like a champ charging through those hard packed curb mounds like there's nothing in the way! Thanks all for your help. (edited to correct a typo)

Can't believe I'm resurrecting a post from two years ago, but goshbegee, this was one of the first things that came up on a google search! I have finally unseized the shift rod adjustment barrel, and can guess an adjustment but don't see one listed in the manual. It's a Model 10962 (from 1969, going on it's 43rd season?) which I believe is covered in this manual: http://apache.ariens.com/manuals/prm-10000.pdf Is there a proper way to set the length of the shifting rod?
