Deutz Allis 1920 60" Mower Deck gearbox repair

Recommended Posts


Hello all and I would like to thank you for your help in advance. I have my fater's Deutz that he purchased new in the late 80's. Love this tractor, been mowing with it since i was a kid. Here's my problem. The Durst gearbox is not holding gear oil. I cannot find a simplicity dealer that can help with finding the correct bearings and seals for the input and output shafts. Could you point me in a direction to get this serviced and working again. I have replaced bearings and seals before and have a 12 ton press but this is a little beyond my diy, not sure how it comes apart and in what order. Thanks

I have filled it with grease. Most of it was on my floor the next morning. It looks like it stayed to the level of the bottom of the input shaft (pto shaft). It didn't all run out but only 3/4 to an 1" in the bottom of the gearbox when i take off the service panel. So I don't think that the output shaft (mower pully shaft) bearing and seal is bad. It doesn't "sound" bad when i turn it by hand or even when it was running before I noticed that the level was way down.

Durst or Curtis? Post the Mfg. No. of the tractor and deck and I will give you the numbers. I believe the seals are 118117 but can check.

Grease isn`t going to work. It takes a oil.

Not sure what its worth, but Id sell it for 30 plus shipping.Ill see if it will fit in a flat rate box without the mounting bracket which should be the cheapest way.Ill check tomorrow after work and get back to you.Bill

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
