Charlie P --Thanks for the exploded view of the 782 Axle (PN 759-3270) highlighting the spacers, PN 750-3002 (see below), but I'm not convinced that replacing the spacers will "take up the slack" in the steering that I'm finding, especially on the LH side where the drag link engages the spindle. I'm thinking that the spacers need to be bushed inside the axle, as shown further below for Model 1782 (PN 759-3271).
And anyway, there is still significant play/wear at the 3/4" center pivot bolt. The only way I can see that ever going away is by bushing the axle and employing a shortened 7" bolt instead of a standard 5.25" to eliminate wear at the threads.
The only axle I can find that has bushings on the spindles is the one that fits a model 1782 (among others), PN 759-3271.
The fellows who wrote up the Super Steer Upgrade (Wyatt Compton & Ken Updike) that I found posted on your site appear to have used the axle that was originally fitted to a Model 1541 (among others), PN 759-3549, which employs a 3/8" ball joint on the drag link at the steering column.
While Randy Swartz, in his posts in the MTD/CCC Forum reports using an axle for a Model 1863, PN 719-3100. (The same part is listed for Model 1440 among others.) He had a time fitting the 1/2" ball joint on its drag link to the steering column.
Again, because (1) I can't find evidence that Super Steer Upgrade has been widely employed, (2) I have doubts about sourcing and fitting the parts, and (3) no doubt that the whole thing will likely wind up costing me over $1,000 (assuming use of new parts).
It seems to me, after my studies, that bushing the parts most prone to wear is the most elegant solution; guaranteed to eliminate all slop, while allowing for proper maintenance and, if necessary, replacement of worn parts.
I was just wondering if anyone else had tried the same approach to the problem.
Perhaps I'm obsessing about the issue. But I swear there is more play in my axle that mere replacement of existing parts will repair. Maybe other people don't have the same problems I'm finding. The tractor has certainly seen some use, the (non-functioning) hour meter stands at 0690.9.
The previous owner replaced the original Series I KT17, and I've replaced his B&S 16 HP replacment. But unit's Hydrostatic transmission seems solid, the deck works OK, the Kohler M18 looks like it will run forever. I love the way CC works, and I hate to give up on the project, yet I hate to compromise so much on the steering.
Bushing the axles seems like an easy out to me right now; either that or just throw it all back together and try to forget about it for another year.
