Raymarine Tiller Pliot Ram

[Kestrahl]

Does anyone have information or links about disassembly and servicing of the rams from ST-4000 S1 and SPX-5 and general information on issues. We have 2 backup rams, one of which the thread had worn out (it was brought 2nd hand and had done a lot miles) And another which makes a loud clicking sound when in use and under load (bearing race?) The thread looks fine and hasn't done alot of work.

Does this help? It is for a Raymairne ST4000.

Cheers,

Andrew

The clicking sounds like a worn rubber belt to me. Cheap to replace.

The above PDF is really helpful for self servicing.

The ST-4000 doesn't have a belt, only the ST-1000 and 2000

Water ingress seems to be a major problem with these either when it rains or you have spray coming onto the unit

Our new ram now is worn out after 5000 miles of cruising. Does anyone know a company in the states that sells just the ram itself? Defender/West etc have the corepack but we don't need the course computer.

I ditched the wheel on my boat and thought I'd just buy the SPX5 GP Ram. Sorry, no source that I've found. If anyone comes up with a source, sing out.

Looks like the only solution is to buy X5 GP core pack just to get the ram. In looking at pricing, the GP core pack is nearly double the X5 basic core pack. In looking at the specs, torque ratings for both are the same. What makes the GP version so much more expensive???

I sent mine in for repair years ago, I forget the details now, but I received one that works.

Seems now there is a flat rate:

The only company that replied to my email was west marine, who will sell the ram by itself. Its not much less than the corepack - only save $150.

As far as anyone can tell the only difference with the GP version is a bigger motor. Which doesn't make sense with the price difference. Since the screw and bearing race seem to be the components to wear out first then I don't see the need for a bigger motor. Also the motors are replaceable (you can buy a replacement) as opposed to the other components.
