Is this too much grade for a K46 transmission?

Tuff Torq K46 Tranny
Comments (80)Thanks to this Thread I was able to repair the LT180 I just bought at an auction. All was good until about 30 minutes of mowing when the world stopped turning and the machine was barely moving. After reading all the info above I took a slightly different approach to remedy the slow trans-axle condition. Taking the least aggressive path, I was curious if just a fluid change would make a difference, I decided to jack the rear end up and pop a couple drain holes into the Axle cast housing where Tuff-Torq suggests. Here is a Link https://www.tufftorqservices.com/EnvEEdefault/FlatHTML/TechInfo/ttcoil/pdfs/K46%20Drain%20Port%20Location.pdf I used a 1/8 stubby drill as not to injure any interior components, both holes drained over night. I then added 2 self tapping screws 1/2 inch long with a neoprene washer. Without the deck on the machine I was able to reach under the frame and pop the fill hole cover off using a stubby flat screwdriver. I cleaned up the magnet and filled the unit. 24 inches of 3/8 clear tubing and a small funnel allowed me to add back the 2 quarts of cheap 10-30 oil for my test. Popped the magnet and cap back in place and DONE! I am pleased that the result was success, the machine runs very well without growling and slowing after 30 minutes of use. My intention is to replace the 2 small drain holes with real drain plugs after about 5 hours of use and refill the unit with synthetic oil for hopefully many more years of use. Happy Mowing!!...See MoreNew CVT transmissions. Any experience?
Comments (79)I have a Craftsman 917.255810 42" 19 HP Briggs & Stratton Fast Auto TurnTight® Riding Mower equipped with a General Transmissions RS800 CVT (constant variable transmission). It was purchased on Black Friday, Nov 24, 2017. I also purchased the correct Craftsman 9 bushel, 3-bin bagger to fit the mower. I used the mower to 'get up' leaves 3 times in the fall of 2017. I stored the mower in a shed, out of the weather, until this spring. I have used the mower 2 times to mow my lawn. Basically to knock down the onions and dandelions. There was little or no 'real' grass to mow yet. My front yard has a slope that I run side to side on. The CVT started sticking, becoming difficult to change from forward to reverse and back, in the fall. In the Spring it became an issue to the point I contacted Sears Service and they sent out a service technician. He was a contractor for Sears and had enough work with Sears that he didn't do anything else. One of the common problems with this CVT is debris jamming the exterior workings, ie. Variator Levers, Inversion/Variation Control lever (forward/reverse), Drive Variator (variable pulley), etc. The Sears Tech said that my CVT was one of the cleanest he'd ever seen (I attribute this to the few times I had a chance to used it & blowing it off with a leaf blower.) and was not a debris problem or issue. The short of it was that the CVT was failing. The Tech said that the GT CVTRS800 was one of the main issue on most of the calls he was dealing with. He said that Sears & Kubota had gone away from it and were mainly using a hydrostatic transmission again. He did say that John Deere was using it in their new 'consumer grade' mowers sold at big box stores like Lowes & Home Depot. My options were to continue to call Sears Service for 2 years while the mower was still under warranty, then purchase a yearly Service Contract for about 1/2 the cost of replacing a CVT, or try to sell the mower and purchase something else. The Tech did say that he had worked on one CVT RS800 equipped mower that didn't have these issues. It was used on a yard that was about an acre or less and as flat as a 'golf course putting green'. The Tech is coming back in a few days to replace the CVT at no cost to me. The Tech said that the CVT was originally designed to drive the blades and wheels of snow throwers/blowers and it did fine at that. GT tried to repurpose it for Lawn tractors to less than mixed results. I guess I'll ride this horse for two years and then try to sell it to someone with a pool table flat lawn. I'm also with toefungus wondering if there will be a Class Action Lawsuit as a result....See MoreAnybody know about the K58 Transmission?
Comments (13)the k58 is ok but is also found in lower end tractors along with the k46 and k60 I would not say they are junk but there are better ones such as the k71 found in the x500 but pulling just a aerator or something like that your dealer is right go across not up and down and you will be fine . also they are not serviceable by design but you can still service them they dont have a drain plug only a vent tube so the easiest way is to unbolt the hydro unit from the tractor and take the plug out of the vent tube then tip the hydro upside down so the vent tube is pointing straight down and let it sit that way till the oil all runs out then refill it with fresh oil by dumping it into the vent tube it takes a little while to get it refilled but if you use a funnel and run a small rubber hose into the funnel to act as a vent then pour the oil into the funnel with the hose in place it allows faster filling because the air has a way to escape as you are filling it up afterwards just bolt it back on and reconnect everything and if you have a little lever on the back that says bypass or release start the tractor with both rear wheels off the ground and pull the release lever which bleeds the air out of the system while the tractor is in drive after about 10 mins put the tractor back in neutral push the lever back in and take it for a drive...See MoreHelp Troubleshooting K46 Transaxle
Comments (17)the pulley should not move at all i would think. what about your pedal linkage, did it have any slack where it attaches to the tranny? that is what determines how fast you go, and therefore how much force is applied to the tires. if it is only partially engaging you could get them same exact symptoms as well....See Morerustyj14
