, I have a Volvo DP drive and was considering rebuilding the rams with a repair kit from the US available on eBay 160773196346 is the item number for the kit I need but they will do any one. There is even a tool provided to unscrew the top. What boat is it fitted to.

Hi.

I have got more info on how to do a rebuild on another forum "Motor Boats Monthly" their is a post on there by jparham titled "Think I mended my KAD 32 DPE Rams" if you do a search on this it will give you pictures of the rebuild that he carried out on his own rams. Since viewing the post I have stripped down the leaking ram on my outdrive which is a Volvo Penta DPR drive. I was looking for a tool to remove the end from the ram and looked at the type of spanner used for changing the disc on an angle grinder,luckily for me when I tapped the ram end with a dot punch it started to open fairly easy so I proceeded with it's removal and was able to pull out the plunger of the ram intact, all of this was done with the ram attached to the transom shield as when I tried to open this end which is in the engine bay it would not budge. Thats as far as I have got for the moment I will update progress if you are interested I plan to take the ram plunger into a local hydraulic firm in Cork next week to get new O rings. Oh yeah the boat in question is an Excalibur 8.7 mt wrap around fitted with a VP D6 350hp.
