Frequently Asked Questions

Which transmission parts fit a John Deere 1010 crawler?

Broken Tractor carries several 1010 crawler transmission parts, including the Metallic Clutch Disc (T15801), the Transmission Bearing Cone (JD8194) and Race (JD8230), and the Transmission Input Shaft Bearing Cup (JD8225-). Some 1010 parts are split by serial number, such as the 4th Speed Gear (T19222) and 1st & 2nd Speed Cluster Gear (T16598) for units after SN 15258, and the Input Shaft (T23653) for units after SN 43053. Check your serial number against the fitment listed on each part before ordering.

Why does the transmission seal I need depend on the serial number on my 350B?

John Deere changed the transmission seal on the 350B at serial number 142199, so we list two seals. Use the Transmission Seal AT12822 for 350 and 350B before SN 142199, and the Transmission Seal AT13945 for 350B after SN 142199 along with 350C, 350D, and 355D. Confirm your serial number to pick the correct seal.

What transmission bearing cups are available for the John Deere 350 dozer?

Broken Tractor offers multiple transmission bearing cups for the 350, including JD8225 and JD8187, plus the Bearing Cup Race JD7444. The JD8187 also fits the 350B before serial number 142199, and other cups like JD9117 cover the 350B through 355D. Match the part number to your model and serial range to get the right cup.

What length shift cable fits a John Deere 350 series dozer?

We carry a 60 inch shift cable (AT83335) that fits the 350, 350B, 350C, 350D, and 355D dozers. This same cable also fits several other John Deere machines, so verify the part number against your unit before ordering.

Which speed gears does Broken Tractor carry for a 350 series dozer transmission rebuild?

Broken Tractor stocks speed and cluster gears including the 4th Speed Gear (T19222), 3rd Speed Gear (T19462), 2nd Speed & Reverse Gear (T16326), and the 1st & 2nd Speed Cluster Gear (T16598). Most fit the 350 through 355D, and the 4th speed, 3rd speed, and cluster gears also fit the 1010 crawler after serial number 15258.
