707-99-38720 Hydraulic Cylinder Service Kit for Komatsu

The 707-99-38720 is a hydraulic cylinder service kit for the boom cylinder installed on Komatsu hydraulic excavators. It is used with Komatsu PC160 and PC180 machine models, including the PC160LC-7 and PC180LC-7K machine versions.

This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts). The kit is intended for servicing the boom hydraulic cylinder on the listed Komatsu equipment and is supplied as a service-kit assembly rather than as a complete hydraulic cylinder.

The product application is defined by the machine model and cylinder function: the kit is intended for the boom cylinder of the specified Komatsu excavators. It should not be treated as a general service kit for every hydraulic cylinder or every machine in the PC product range.

Fitment

• Komatsu PC160 hydraulic excavator
• Komatsu PC160LC-7 hydraulic excavator

• Komatsu PC180LC-7K hydraulic excavator

The listed fitment identifies the Komatsu equipment on which the 707-99-38720 kit is used. The application stated for this part is the boom cylinder. The machine series and model designation should be checked against the equipment identification before installation, particularly where several cylinder configurations may be used within a model range.
