How do I pack my leaking cylinders?

When you ship your cylinders to us to be rebuilt, they should be prepped and packed carefully to prevent damage and avoid fluid leakage.

Before packing, make sure to remove all fluid. To do this, point the cylinder hose ports or hose ends, where applicable, into a bucket and remove fluid by extending and retracting the cylinder rod end-to-end several times. Be sure to point the cylinder ports into the bucket and away from yourself.

Once drained, push the cylinder rod completely into the cylinder. Wrap the exposed cylinder rod with bubble wrap, foam, or any other material that will protect it from getting damaged. Place cylinders in a plastic bag to contain any residual hydraulic fluid. Wrap each cylinder individually before placing it in a box for shipping. Use plenty of space filler in the shipping box to keep the cylinders from shifting around.

Make sure to include your contact information including name, phone number, and return shipping address. We have a Customer Info Form available that you can print out and include in the box with your cylinders.

What is the warranty on rebuilt cylinders?

Our rebuilt cylinders carry a 3-year warranty. If a cylinder fails within the 3-year warranty period, we will repair the cylinder at no charge.

Damages not covered by the warranty include:
Hydraulic cylinder and/or hose damage caused by mishandling, improper installation, and malfunctioning convertible top system components will not be covered under warranty.

What is the warranty on the convertible top hydraulic hoses?

Our 27,500 psi hoses carry a 5-year warranty.

Damages not covered by the warranty include:
Hydraulic cylinder and/or hose damage caused by mishandling, improper installation, and malfunctioning convertible top system components will not be covered under warranty.

What is the warranty on the Hose Couplers?

When properly installed, our Hose Couplers are warrantied for 5-years. To receive a warranty replacement, the Hose Coupler in question must be sent back to us along with the attached hoses on both ends for inspection. The returned Hose Coupler will be inspected to make sure that it was properly installed.

Damages not covered by the warranty include:
Any damage due to tampering, mishandling, or improper installation of the Hose Coupler will void the warranty.

What is considered a “good core”?

A good core is a used cylinder that has not been physically damaged or tampered with in any way and is free from rust and pitting. Damage and tampering encompasses missing parts, and/or physical damage to the cylinder, the cylinder rod, or the hoses.

Often times older model cars may have been resold several times and previous attempts to repair the cylinders may have been made. Before sending us your cylinders, carefully look for missing parts and damaged or tampered-with cylinder components. Cylinders that were previously tampered with may not be eligible for a core exchange or core refund.

What if my cylinders were tampered with or previously damaged?

If we find any damage during our inspection process, we will call you to discuss the damage before we start any work on your cylinders. Often times we can still repair your damaged cylinders.  Additional costs will apply based on the extent of the damage.

What if the cylinder rods are rusty and/or pitted?

Please inspect your cylinder rods very carefully before shipping to us to know the condition of your parts.  Cylinders with rusty rods cannot be rebuilt properly without replacing the rods. For an extra cost, we replace the rusty cylinder rods in the most common rust-prone cylinders. If the rods need to be replaced, we will contact you to discuss cost and to obtain approval before beginning the rebuild.

What happens when Cabriolet Hydraulics receives my leaking cylinders?

When we receive your cylinders, we perform a detailed inspection. We look for missing part, physical damage such as bent rods, drilled holes, scrapes, dents, rust and pitting, or any other alterations to the original factory cylinders. If your cylinders are free of damage and all the parts are intact, we begin the repair the same day that we receive your cylinders.
