transaxel grease contamination

Recommended Posts

jb3179
Hello all and thanks so much for the information I have read within these pages. I am fairly new to Simplicities as i have only had my landlord 3410 one season but have been a mechainc and fabricator all my life. My question is a simple one though. I changed the gear oil in the transaxel of my 3410H as soon as I got it and have greased the zerk on the axel tube a few times this season and when i checked my gear oil yesterday it was over full and had black colored streaks in it , I assume is contamination from the axel grease, is this common or is there an internal seal that separates that axel grease from the gear oil that I need to replace? How often do you guys add grease to your zerks?

Joe there is no internal seal, because the grease lubes the axle shaft which rides inside the axle tube. There shouldn't be any way for grease to migrate to the transaxle as the axle tube is a solid assembly (folks, correct me if I am wrong here). There are actually 2 grease fittings, one on the outside of the right wheel and one between the transaxle case and the differential. I lube mine once a month during the summer and again in the fall before the winter (less use in the winter than in summer). You should also change the BGB (Bevel Gear Box) fluid if you haven't recently. Also, check the level regularly because that's a very important part of your machine.

Thanks for the advice I thought that was the case but I am still baffled by the over filled condition in the transaxle. It took forever to get that 75w90 in the fill plug and if anything i thought it would be slightly under filled. im going to do all the fluids over this weekend with synthetics. When I got the tractor god only knows how long it had been since they had been changed and i wanted to put some hours on it with new mineral based fluids to clean it out so to speak before i went synthetic. After the winter with synthetics ill check again for discoloration.

Your 3410H is a Vickers hydrostatic. The overfill condition in your transaxle is probably hydro oil leaking into the transaxle. To fix is a big job, as the hydrostatic driven motor is leaking at the output shaft. My HB212 hydro has leaked into the transaxle most of its life. My transaxle is over-filled with hydro oil, and with 1000s of hours it is still working just fine.
