How do I find the right hydraulic cylinder seal kit for my Case 680 series backhoe?

Start by identifying which cylinder you are resealing, then match the Case part number from your old kit or cylinder to the SKU. Some kits fit the whole 680 series, such as SKU 1543273C1 for the 680E through 680L, while others are limited, such as SKU 1543252C1, which is listed for the 680K. Fitment can also depend on serial number, so confirm your model and serial before ordering.
