Main Lift Cylinder - Cadillac XLR

$250.00

You send in your leaking XLR Main Lift Cylinder, and Top Hydraulics rebuilds it.

  • Top Hydraulics replaces & upgrades ALL seals in your cylinder with our superior proprietary material including rod seals, gland seals, port seals, plug seals and piston seals. Top Hydraulics also manufactures and installs our own precision CNC machined front caps in these cylinders, so that the tiny OEM rod seals can be replaced with Top Hydraulics' u-cup seals for a far more reliable seal and much longer service life.
  • No surcharge for dented or corroded cylinder shafts - shaft replacement as necessary is included in the rebuild charge.

The original seals in these cylinders are made of a material that fails within 10-15 years, or faster if exposed to contaminants or water in the convertible top hydraulic fluid. Top Hydraulics replaces the original steel gland inside the cylinder with a new, CNC-machined one that accommodates a more sophisticated rod seal, gland seal, and wiper seal for maximum service life of the cylinder. Replaced and improved rod seal, piston seal, cap seal, gland seal, wiper, and port seals make this part better than a brand new one, with an expected service life of 30-50 years under normal circumstances. 

In most cases, the first leak on the original cylinders will be through the mounting hole at the bottom of the cylinder, making it appear like a leak from one of the hydraulic hoses. Next, they will typically leak from the top, and ultimately they will develop internal bypasses. Even brand new cylinders from the dealer can fail again within a short time frame if the hydraulic fluid in your system is contaminated. The rebuild & upgrade service from Top Hydraulics will avoid these issues because our seals are inert to almost any contamination.

Note on Main Lift Cylinders: These are the only ones that have a significant percentage of corrosion on the dark cylinder shaft. This corrosion occurs with the top raised, where water has leaked into the car, and accumulated on top of the cylinder housing where the shaft goes in and out. This corrosion is not always visible when the cylinder shaft is fully extended, because it happens a few millimeters below the top of the cylinder housing. If we notice any pitting on the shaft from corrosion after we have opened up your cylinder, then we will advise you that a shaft replacement is in order, which will cost an additional $100. Top Hydraulics' shafts are made of hardened, polished, chromed stainless steel, which makes them very resistant to corrosion.

These cylinders are very easy to remove from the stowage cover. Remove the mounting pin first that goes through the clevis (fork) first, and retract the shaft. Then remove the bottom pin that goes through the cylinder housing. Last, remove the hydraulic line clips by sliding them in the cylinder's rail. Hang on to the clips, so that they don't get lost. Pull out the hydraulic lines - we suggest sticking the hose ends into a ziplock bag. Cycle the fluid out of the cylinder(s), package well, and send to Top Hydraulics.
