For the Volvo engineers amongst you.

We have got a DP-E trim cylinder with a slightly scored/pitted rod.
The pattern of the scoring is cylindrical, not longitudinal, It has been caused by us having to leave the boat with the leg fully up, allowing barnacles to attach themselves to the rod.

We are looking for a satisfactory method of filling this scoring. Our initial idea would be to do this with Silver Solder and then finely polishing it. Would this work, given that the part would be under water for half the day?

Any thoughts/suggestions would be appreciated.

Most hydraulic work shops deal with sort of damage every day, depending on the diameter they use an assortment of methods to replace the missing metal and the cost is not that high, however is often ceaper to replace the length of stainless steel rod in smaller marine rams.

Hope this helps,

I had my rams refurbished by a local hydraulic shop last year, it worked out at £30 per ram and that included rechroming and replacing the seals. That was on VP290 drive.

Thanks for that.
Interestingly we thought that the "rods" had a chromed surface as well. We were therefore going to de-chrome them then re-chrome them to cure our problem.
However, we discovered a couple of days ago that in fact they were polished SS. Hence our belief that Silver Solder may be the way to go.

Where are all the metal workers on here, when you need them??

Thanks oh antipodean!!

Unfortunately Volvo want to charge megabucks for the complete item (cylinder and ram) and won't supply the constituent parts /forums/images/graemlins/mad.gif

Furthermore, replacing the complete set is a barsteward to do.

Col of these forums made me a generous offer but unfortunately the parts were not the same.

Not sure where to go now.

This is obviously too hard a problem for this "Practical" forum's "experts", so I might have to go to MoBo chat to see if anyone's awake over there. /forums/images/graemlins/shocked.gif
