Drive Sprockets by Machine: Match the Sprocket to the Model
Browse sprocket product information.
The drive sprocket is the toothed wheel that turns the chain, and it is the part where a wrong number is most expensive: the sprocket sets the pitch the whole undercarriage runs on. Two machines that share a track size can still take different sprockets, and the tooth count and hub pattern have to match the drive. This page is the machine side. It sits inside the Drive Sprockets guide.
What the sprocket does
The role of sprockets and how the sprocket relates to the rollers set out the job; how tooth count affects performance and how the hub handles torque go into the two numbers that matter.
Caterpillar
The drive sprocket for the Cat 304C CR and 305C CR and why that sprocket fits cover one family; sprocket 2606341 for the 305.5D and 305.5E and the same number in Canada the next. On the crawler side, the Cat D6 dozer sprocket and drive hub fitment are the dozer entries.
Bobcat and the compact track loaders
Sprockets for the Bobcat T200, T250 and T300, roller 7165109 for Bobcat loaders and its suitability and price cover Bobcat; the T770 and T180 drive issue and sprocket wear on the Cat 259D, 289C and 299D are the compact loader cases. The Cat 259D replacement guide is the worked example.
Kubota, Komatsu, John Deere and the rest
Sprocket RC41714430 for Kubota and what that number is, with the Kubota U-series and the precision fit alongside; the Komatsu bulldozer sprocket and the mining variant cover Komatsu, sprocket 2056268 for John Deere covers Deere, and the Hitachi EX200 and EX400 sprocket and the Hyundai 81EN-10014GG fill in the rest. The tracks and sprockets matching guide ties it together.
Confirming before you order
Cross-reference the number, then confirm tooth count and hub pattern against the sprocket you are removing - the OEM compatibility guide walks through it. The Drive Sprockets guide covers the rest, and the wider system sits under the excavator undercarriage parts guide.
FAQs
Can I change the tooth count to change speed?
No. The tooth count is set to match the chain pitch and the drive; changing it changes how the chain engages and will not run correctly.
Are sprockets for track loaders and excavators the same?
Only where the number crosses over. The tooth form and the hub are machine-specific.
Do I need a new sprocket with a new chain?
Where the sprocket is worn, yes - and the guide below explains why pairing them badly is the expensive option.
