Cylinders and distributors upgraded by Top Hydraulics should easily outlast your car! W124 E-Class 93-95 Top Hydraulics installs port seals that are tighter than the originals, just in case the hydraulic line fittings have been scratched. DIY removal of the brass rings will almost certainly destroy the brass rings. They are secured by precisely machined brass rings (accuracy about 1/100 mm). Port seals have a special shape that makes them seal under pressure. It also applies to the front distributor p/n 1298000022. Port seal failure is becoming more and more common as the R129s age. They seal the hydraulic lines where they are pushed into the cylinders. They are usually the last seals to fail, but these o-rings are penny items.Ĥ) Port seals. These are just o-rings that seal the top cap of the cylinder from the housing. Crumbling piston seals can block valves or pinholes inside the hydraulic system, and it can be difficult to diagnose a piston seal failure without testing several cylinders once you find that your top is moving slowly or not at all.ģ) Gland seals. Early model years have the added problem that the piston seals swell up and make it very hard to move the piston inside the cylinder. Failing piston seals will cause internal leaks, which result in a pressure drop in your hydraulic system. The piston seals have been made of different materials and sizes even in the same p/n cylinders throughout the years. They seal the input and output sections from each other, as the piston slides through the cylinder. These are usually the first seals to fail in the cylinders.Ģ) Piston seals. When they fail, you will see fluid coming out next to the chromed shaft (rod). They are cup-shaped and seal the piston rod from the rest of the cylinder. Top Hydraulics replaces and upgrades ALL seals in the cylinders with our superior proprietary material:ġ) Rod seals.
What fails most frequently, are the other seals, which have special shapes for proper function. Every R129 cylinder has one o-ring, and those rarely ever fail. Rebuilding these cylinders is NOT a matter of changing o-rings. (The left tonneau cover lock was omitted after 1996.) The original seals in the hydraulic cylinders, aka rams or actuators, will eventually fail in every R129, unless it gets wrecked prematurely, even if you never drive the car or have never used the top before. Model years 1990-1996 have twelve hydraulic cylinders, while 1997-2002 models have eleven hydraulic cylinders that move and lock the roadster soft top.
We have two order methods: Either you send in your cylinders first, or choose to "Order now with Core Exchange".
