718H

Is the AC 718H rare? I cannot seem to find any info? Also what is a ballpark figure for bevel gearbox rebuilt? I got the motor running Wednesday but the bevel box isn't turning. I think the "DRIVEN GEAR" is missing some teeth. Are these rebuilt in the tractor or are they removed from the tractor? Has anyone heard from Sandy Lake Implement lately??? I sent them two e-mails and got no response? P.S. Buy the way once again you guys are right the box on top of the Kohler was the rocker arms!!!

Most of the time you should remove the gearbox to work on it. Be prepared if you do remove it, the gearbox is what holds the two halves of the tractor together. The gearbox is pretty easy to rebuild and parts are available from a dealer. I think the hardest part was getting everything back together. PhilD

I just rebuilt the bevel gear box in my 7012H. Replaced both gears, 1 shaft, all bearings & seals, all retaining rings & woodruff keys, drive gear washers & bolt, shims, gasket & misc. Depending on what your box needs, parts cost should be around $200 - $300. Sandy Lake Implement did have a used box. I never removed & rebuilt one of these before, and it was a "challenge" at times. Next time (I hope not on mine) will be a lot easier now that I've done it once. Just make sure you use 2 short shaft convex washers, installed correctly, and the special thin head bolt (torque 27 ft. lbs.). Also, take your time installing the correct amount of shims to set the backlash. PhilD is right, the box should be removed to rebuild it. I removed my box, rebuilt it, but then I removed and reinstalled the long (output) shaft so I didn't have to remove the frame side. Good luck........

I rebuilt mine on my 716H this year. If I remember parts was about 250.00. You have to split the tractor ( easy, 4 bolts and remove the drive shaft from motor). Once you split the tractor the gear box is easily accesable from the back half. One very important issue is the shims between the case of the out put side of the gear box and the frame of the rear section of the tractor. Thes shims are what achieve the proper mesh for he two gears. Make sure that there is not to much play in these gears. May cause another rebuid later.
