TuffTorq K46 Repair Guide with Pictures

[wactbn]

I called tuff torq today and they told me to buy the rebuild kit $320.00. I asked about cheaper options Derick said to get the pump block kit $58, the cylinder block kit $71, filter $8 , sealant $13, and center case A $88.total $240. My question is do I really need center case A. what is it can I just clean up the old one, is it a good investment? The mower is in good shape the engine is strong. the transmission just go to weak. I think the mower could last another 10 years but like any big investment in an old item, I still worry about other problems and just end up throwing it away. Any feed back and pointers would be much appreciated.

Like you, I started out planning on buying a similar parts kit from Derrick, but it was going to be close to $300 with shipping. Since I only paid $750 for my used L130 (with the busted K46) last summer, I simply couldn't justify that repair cost. I ended up buying just the fan, filter, vent & cap, oil drain bolts from Tuff Torq ($28 in parts + $16 S&H!) and bought the sealant and Castrol 5W50 synthetic from the local auto parts store. In hindsight, the oil drain bolts were a total waste of time and money since the best way to drain is to remove the K46 from the mower and turn it upside down anyhow.

If you have a few hours and elbow grease to spare, just re-sand the revolvers and center case by hand. Or take them to a machine shop. It will be much cheaper than buying new ones. I would still recommend buying a new filter, cap & vent from Tuff Torq. It's up to you to weigh time vs. money.

Do they sell synthetic elbow grease?

Did you verify that the pump and motor were spinning before you put the transaxle back on the mower? Did you top off with more oil after doing the air purge? I did my air purge on the shop bench by using a clamp to release the brake, and spinning the pulley by hand. I saw quite a lot of bubbbles in the oil as I was rotating the pulley and watching the axle move (about as slow as the minute hand on an analog clock).

When it's jacked up, does the differential work, i.e. spin one wheel, and the other wheel spins the opposite direction? This would check that the differential and axles aren't binding.

I noticed the the bottom one closest to the pulley spinning whenever i spin the pulley but never seen the other one move yet..Yes whenever I turn one wheel the other goes the opposite way is that what is supposed to happen ?? The oil didn't drop any at all

Yes, one axle moves from spinning the pulley, while the other didn't for me either. And the wheels do turn the opposite way due to the open differential.

Did you reconnect the brake actuator? Maybe you still need to bleed more air out?

Lots of green grass, What advise can you give on John Deere L110 when the transmission is slipping.
Have replaced belts and no help.
Thanks

Did anyone happen to break this linkage? I'm trying to find or build a replacement.

Just wanted to say that I could not find any 5/50 Synthetic so I used 5/30 Synthetic. I have had no problems at all.

As others have mentioned in other threads found on the net:
1.) Originally came with 10/30 Dino oil so Synthetic is much better.
2.) Splitting hairs between 5/50 and 5/30.
3.) Thousands out there, many without problems at over 1000 hours.
4.) Much of the problems are due to clogged cooling fins on the upper side of Transaxle, thus causing over heating of oil..... Keep top side of Transaxle clean so the cooling fan can do it's work.

Just my 2 cents.

Nettelec, I am interested in getting the parts list for the upgrade.
Thanks
