Rubber and drive hydraulic pump couplers for Kobelco excavators, spanning compact SK60 machines through large SK480 class equipment. These couplers connect the engine to the hydraulic pump and are a common wear item requiring periodic replacement to prevent vibration, noise, and pump damage.

Frequently Asked Questions
What are the signs of a bad hydraulic pump coupler on a Kobelco excavator?
Cracking, chunking, or deteriorating rubber on the coupler are the main signs it needs replacement. A worn coupler can also cause vibration and noise between the engine and the main hydraulic pump. Replacing it early helps prevent damage to the pump itself.
What does the hydraulic pump coupler do on a Kobelco excavator?
The hydraulic pump coupler connects the engine to the main hydraulic pump and transmits engine power to it. It also absorbs torsional shock and minor misalignment between the two. Because it takes that load constantly, it is a common wear item that needs periodic replacement.
Which hydraulic pump coupler fits a Kobelco SK200-6?
Two of the couplers we carry list the Kobelco SK200-6: part number 2418R139F3, which also fits SK200-3 through SK200LC-6, K907 and MD180 to MD200 models, and part number YN30P01009F1, which fits the SK200-6 and SK210-6. Match the part number on your old coupler or your parts book before ordering. If you are unsure which one your machine uses, call (800) 909-7060 and the parts team can help confirm.
Is a Kobelco excavator pump coupler rubber or a drive coupler?
It depends on the machine size. Broken Tractor carries rubber flex couplers for compact Kobelco models such as the SK60 to SK80 series, K903, K904-2 and SK100, and rigid drive couplers for mid and large frame machines from the SK100-4 and SK120 series up through the SK480LC. Check the fitment list for your exact model and dash number, since the SK100 and SK100-3 use a rubber coupler while the SK100-4 uses a drive coupler.
Do your Kobelco hydraulic pump couplers cross to OEM part numbers?
Yes, each coupler we carry crosses to a Kobelco OEM part number. These include 24100U341S1 for SK60 to SK80 and K903 machines, 2418U224S7 for SK100-4 through SK160LC models, 2418R219S1 for K909LC-2 and SK220 to SK330LC models, 2418R605S1 for SK300 to SK350-8 models, and 2418R660S001 for the SK400 IV and SK480LC. Matching the OEM number from your old part is the most reliable way to order the right coupler.
