[tcollins2]

I can't find any model number on the unit.

It's from 12 Meter Express.
It's about 16 inches long.
Here is youtube link.

We have the rebuild kit for the ram $78.12 plus USPS

We also have the ball joint ends.

Trojan part number was 21-334 for the ram.

It does not appear that ram is available any more there is one the same size but does not mount the same. It could be tricky to make it fit.

Thanks.
No repair needed, just trying to find capacity size (displacement) in cc's.
Need that number to find appropriate size of autopilot pump.

How close do you need to be?

Measure OD of cylinder.
Subtract 0.125"
Measure stroke length.
Multiply to get volume, convert to cc's.


4 tie rods look easy enough to remove to determine actual bore, if needed. Note that different amounts of fluid are needed to turn to port vs. starboard.
