K66 John Deere Oil Change How To

[@guidefurlani2199]

Excellent video Rob. Much clarity gained on the K66 Transaxle fluid. Yesterday had to change the fan on top of it, hell of a job, and doing that I realized actually this guy has a need for oil.. lol.. - Great suggestion to plug two holes in the Plate to access the 2 top oil caps, as well as painting the 2 draining screw/plugs. Thank you, great job.

Excellent! Thank You! Your video helped me a lot. I have Husqvarna GT54LS with K66 Tuff torque 190 hrs. A plastic gas tank covers the top of the tranny. I was able to get to the gear side top plastic threaded fill hole plug with the left tire removed and reaching to unscrew it by hand. I drilled and cut to enlarge an existing hole in the back to insert the fill tube. I would have preferred to use full synthetic 5w50 but I had some mobile one 15w50 so I used it. I filled the gear side very slowly with a flex hose inserted from the back and moved the hubs back and forth to get air out. This went very smooth with no issues.... but like I said I was only doing the gear side to start with. I took it for a test ride and the difference was AMAZING. All the speed and torque was back. I have not yet changed the hydrostatic side. but I did make a small square access hole for it on the rear so I could get to the over flow jug. My point is...... I am surprised the result I got just doing the left Gear side. UPDATE: I got the hydro side done. It took a HECK of a LONG time filling through the overfill jug. and purging air. I will check and top off again after a few weeks of use. note: my husky k66 has a hydro side OIL FILTER located at the front side of the transaxle (per the deck side). Its a large flat plastic screw in plug. The machine is is no longer sluggish and moves like new.

I'm happy to hear the video was helpful for you! I'm also glad your machine is coming back to life!

Thanks for posting this...I am changing all belts and hyd oil on a G100 with a K66....the drain plugs were not obvious and your video helped.....

[@RobHoffmann20]

Great! happy to hear it could help you out. Thanks for watching, Cheers!

Tuff torq calls for removing the overflow tube housing, I guess to allow air to more easily escape, it means removing the seat, platform and fuel tank etc. . I upgraded my 510 hour D160 with a k66y, and updated hubs,, wheels and tires. Things are tight. I ll try the overflow overfill method, but it seems like it might take as long as full disassembly. I now also a have a goal of getting air with the front wheels .....great job

Nice , I have a K66 in my D130 Deere. It really transformed the mower.

[@RobHoffmann20]

I couldent agree more, made this a new machine!

I have a Scott’s 2554 with this transaxle in it and it has a fill cap under the seat. I’m assuming that’s for the reservoir, I better check if there’s another one before I get into this job

[@RobHoffmann20]

That's a convenient feature, I can't really say other than this video what you should be looking for.

[@DougWerth]

I just did my s2554. There’s a second fill cap.

just put a used K66 into an L118/ K46 .. new seals and start of fluid/ 5W50 synthetic today, so thanks for helping me see this step in the change which I'll do tomorrow. I'm coveting your TALL seat too!

[@RobHoffmann20]

Very nice! Im glad the video could help you out. The worst part was just burping the air out of the system. Thanks for watching. Cheers!

Great video I know K66 is better than K62 but the cases are same. I have a K62 in my JD 190C and I would like to add those access holes for the gear fill & plastic reservoir. What size holes & where is center for each? The K62 needs to have air purged out during refill. What a PITA, I used my drill on nut for fan (pushing forward & reverse lever back & forth as well as bypass valve) and it took me over 2 hours before I saw the fluid level change. After reinstalling transaxle it still took a while before trans would engage. So I figure fluid levels dropped and access holes would be very helpful.

[@RobHoffmann20]

If your planning to drill holes I would say simply to try to align with the areas you require access to. The placement isn't crucial if you have a flexible tube to use when refilling the unit. Yes Air lock's can be a challenge to work out of the system. Best of luck. Cheers

[@christhefistful]

Good information, thanks for doing this.

[@RobHoffmann20]

Thanks for watching and for the feedback. Cheers!

Hey, thanks for the video. My simplicity has the k66, i believe, and a locking dif. I think its a 2004 Conquest.

[@RobHoffmann20]

That locking diff would get my mower to the next level! Haha thank you for watching, hopefully this video helps you out some. Cheers!

[@soulmatejenn3974]

did you use the same type of oil in the plastic tank?

[@RobHoffmann20]

Yes, its the same oil type

@@soulmatejenn3974 I was lucky enough to get some in from my local automotive parts store, I would think it could be ordered in if you requested that.

[@cristogreyling4736]

do you know where I can get a k66 - who still sell them?

[@RobHoffmann20]

RjrTractor . com is where my kit came from, it was a complete kit for install on the machine. it was very easy to follow. however it's pricey

[@davidmorgan8612]

I can’t find anyone doing maintenance on a k62
