Part of the Kubota Parts Manuals.
Looking up part numbers for a Kubota 1600 or 1600DT? This OEM catalog (#67111-8282-4) covers both the standard and four-wheel-drive models across 107 bookmarked, searchable pages. Exploded diagrams break down the engine, transmission and drivetrain, and chassis and body assemblies, with callout numbers tying each piece to its catalog reference for quick cross-checking. The transmission case takes shims in 0.3, 0.5, and 0.8 mm thicknesses (page 31), and the 1st shaft runs on a 6304 ball bearing (page 37). Separate front axle sections distinguish the 2WD model (tire size 4.00-12, page 95) from the 1600DT (tire size 5.00-12, page 105). Order the wrong part and you wait another week. Get the right number the first time.

Kubota 1600, 1600DT Common Problems This Manual Covers
Kubota 1600DT front differential rebuild, the pinion shaft bearing markings rusted off and unreadable p. 101
Open the front axle exploded view on page 97 for the 1600DT. The front differential pinion shaft bearing (Ref. 24, page 101) does not have its size listed in the remarks. Confirm the bevel gear case shim 1 at 0.5 mm shown on page 98 before ordering, then verify callout numbers against your serial number range in the parts index.
Manual Section: Front Axle (1600DT)Can't identify the 1st shaft ball bearing for the gearbox, the old one's markings are rusted away p. 37
Refer to the 1st and 2nd shaft parts diagram on page 37. The 1st shaft ball bearing is a 6304, listed on page 37. For the creep assembly, that needle bearing measures 20x26x8 mm per page 38. Cross-reference both catalog numbers against the parts index before placing your order.
Manual Section: Transmission and DrivetrainDifferential ball bearing worn out, need the exact bearing number from the parts list p. 43
Pull up the differential parts diagram on page 43. The bearing is listed as size 6010, confirmed on page 43. If you disturb the transmission case shims during teardown, note that page 31 calls out three thicknesses: 0.3 mm, 0.5 mm, and 0.8 mm. Match each callout against the parts index.
Manual Section: Transmission and DrivetrainOrdering replacement front wheels and tires, unsure which size the parts list specifies p. 95
Turn to the front axle parts section starting on page 92 for the 1600. The listed front tire size is 4.00-12, confirmed on page 95. Match the wheel and weight callout numbers from that exploded view, and double-check against the parts index so you don't accidentally order the 1600DT wheel (5.00-12).
Manual Section: Front Axle (1600)Frequently Asked Questions
What are the replacement specifications for the ignition switch?
The catalog lists the main ignition switch as "ASSY KEY, main switch" under part number 66711-5518-2. A separate replacement key is listed individually as part number 66711-5514-3.
What front tire sizes does this catalog list for the 1600 versus the 1600DT?
The catalog specifies 4.00-12 for the standard 1600 model (page 95) and 5.00-12 for the 1600DT four-wheel-drive (page 105). Ordering the wrong size is a common mistake when switching between variants, so confirm your model designation before placing the order.
What bearing sizes does this catalog specify for the transmission and differential?
Three transmission bearings are called out: the 1st shaft ball bearing is a 6304 (page 37), the creep assembly uses a 20x26x8 mm needle bearing (page 38), and the differential takes a 6010 ball bearing (page 43). Cross-reference callout numbers in each exploded view against the parts index before ordering.
