Reseal service for Roll-Over Bar Hydraulic Cylinder Pair
Replaces and upgrades all seals inside the roll-over bar's hydraulic cylinders. Core exchange is NOT available for this part. Send in your parts for rebuild service.
Roll bar leaks are not very common yet, because Mercedes' supplier used seals almost as good as Top Hydraulics'.
Top Hydraulics only works on the hydraulic portion of this device. The emergency deployment feature of the roll-over bar is electro-mechanic, and it is not affected by Top Hydraulics' rebuild/reseal service for this hydraulic cylinder. Just for completeness, it is hereby clarified and agreed that Top Hydraulics is explicitly not liable for any emergency deployment of the roll-over bar, or failure thereof.
The hydraulic cylinder is used to "manually" raise and lower the roll bar. An emergency deployment disengages the roll bar from the hydraulic cylinder assembly via an electro-magnetic solenoid. The roll bar then gets pushed up quickly via spring power. If the roll bar has been emergency-deployed, then pushing the UP button will extend the hydraulic cylinder and make them re-connect. Subsequently, the hydraulic cylinder can pull the roll bar down and thus re-energize the spring for emergency deployment.
The hydraulic cylinder is complicated, and it has numerous seals inside. A special feature is the cylinder staying in the locked-down position unless it gets hydraulic pressure to extend. Top Hydraulics upgrades all seals inside the cylinder, including the port seals which are located where the hydraulic lines enter the cylinder.
Return shipping within the US via USPS Priority Mail is $15. International Express Mail shipping $80.
