Front Mount Hydraulic Steering Cylinder Seal Kit is Great for Use in Marine Applications!

Used to repair leaking or weeping cylinder seals. Rebuild the outboard front mount hydraulic cylinders, preventing the leaking of fluid and optimizing efficient performance

It is critical for you to check the cylinder rod to see whether it has scratches, nicks or damages in anyway. Any damages found, the complete cylinder must be replaced. Failure to replace a damaged steering cylinder will result in seal failure and possible loss of steering. Do not remove shaft from steering cylinder. Bleeding the system to remove any air, compatible with Seastar Hydraulic Oil HA5340 only. Check for smooth operations and full travel of the cylinder. Check for no leaking.

Note

The smallest imperfection on the shiny steering rod will cause a new seal to fail real quick. Remove the internal steering rod and then take some 1500 then 2000 grit wet sand paper and go over the full length of the steering rod (take your time!!). Clean rod up, lube it with hydro fluid and carefully reassemble the steering system.

Using Instruction

1. Loosening the Seal Gland. Turn the outboard hard to port; place the pin wrench in the holes of a gland. And use a 5⁄8-inch box wrench on the nut on the port end of the piston rod. (NOTE:Turn counterclockwise on the pin wrench with opposite pressure on the box wrench to loosen the seal gland)

2.Removing the Support Bracket. Use a 3/4-inch socket wrench to remove the nut and washer securing the support bracket to the support rod. (Do the same to the piston rod nut and washer. ) Use wrenches on the opposite ends to keep the rods from turning. With hardware gone, pull off the support bracket.

3. Use the pin wrench to remove the Old Seal Gland.

4.Install the New Seal Gland. Place the tapered guide tool from the kit on the end of the piston rod and lubricate it and the piston rod well with oil or grease. Carefully slide the new seal gland over the guide and onto the piston rod until it reaches the cylinder. Screw the seal gland into the cylinder, but don't tighten it yet. Remove the guide tool; it is not part of the final assembly, but you will need it for the other side.

5. Reinstall the Support Bracket. Reconnect the support bracket to the support rod and piston rod and replace the washers and nuts, tightening the nuts against the washers. You may need to use wrenches on the opposite nuts to tighten sufficiently.

6. Tightening the New Seal Gland. Use the pin wrench to tighten the new seal gland while using a 5⁄8-inch box wrench on the starboard end of the piston rod for counter torque.
