Hydraulic Power steering system

Hi there.

Does anybody have the manual for the hydraulic steering system in the attached picture?

I need to know the location of the bleed valve in the cylinder.

The cylinder has a sticked on the bottom that says:

Yamaha
Hydraulic Cylinder type YMM-23010-00

It has two tiny flush mounted rubber caps on one side.

Cheers
Shahid

Possibly Ultraflex?

Thanks Chris...it does look the same. Their site does not have any maintenance details though. Can't seem to locate the bleed valve(s)

Update

the cylinder is infact an Ultraflex model.

The bleed vent is part of the filler cap itself, mounted behind the steering wheel.

You say you need to bleed the cylinder. The hoses attach to the steering cylinder by a compression joint to one side of a tee piece. The otherside of the tee piece has a spigot, put a short hose on each spigot then put the hose into a receptical to catch the fluid. Back off the compression nut on the spigot side to bleed the cylinder. Make sure you keep the helm topped up with steering fluid all the time. By turning the steering one way then the other you can then bleed off any air in the system.
Hope this helps.

No... the cap on the Steering wheel is to top up the Oil reservoir. You must keep this full to the top whilst you are bleeding the cylinder as described in Aquatecs post.

When I fitted my steering system it came with a pipe that fits into this threaded hole on the top of the steering pump the other end of the pipe connects to a full bottle of fluid. You then loosen of the bleed fitting on the cylinder and turn the steering wheel the correct way to pump fluid out this then gets rid of any air in teh system.

Before you start bleeding each side you must have the engine turned hard over in the correct direction as well.

Really you need to get yourself an instruction manual before doing this.
