The GP-RIPPER TILT 4T9977 cylinder is a critical component in heavy machinery, particularly in Caterpillar equipment
designed to facilitate the tilting action of rippers. Here's how it works:
Functionality: The 4T9977 cylinder is a hydraulic cylinder that is part of the ripper system in heavy machinery like Caterpillar's
D10N, D10R, and D10T models. lt is specifcally designed for the tilting function of the ripper, which is used to adjust the angle
of the ripper for optimal digging and grading performance.
Operation: in operation, the hydraulic system of the machine supplies pressurized fluid to the cylinder. This pressure causes
the piston within the cylinder to move, which in turn actuates the ripper to tilt. The tiling action is essential for tasks such as
breaking up hard ground, clearing rocks, or leveling soil.
Components: The cylinder consists of a cylinder barrel, piston rod, and gland. These components work together to convert the
hydraulic pressure into mechanical force, enabling the ripper to tilt effectively.
Maintenance and Warranty: Proper maintenance is crucial for the longevity of the 4T9977 cylinder. Manufacturers like
Bedrock Mlachinery offer a limited warranty that covers defects in workmanship and materials for a specifed period, usually
12 months from the shipping/invoicing date. lt is the customer's responsibility to maintain the equipment and report any
defects promptly.
Specifcations: The 4T9977 has specifc dimensions and weight, with a bore of 209.6 mm (8.25 in) and a stroke of 660 mm (26
in). This makes it suitable for the intended machinery and ensures it can handle the required forces during operation.
Replacement and Availability: The 4T9977 is available as an aftermarket part, ensuring that operators of Caterpillar
machinery can replace worn or damaged cylinders to maintain optimal performance. The part is stocked by various suppliers.
ensuring availability and often offering a warranty for customer peace of mind.
