Volvo hydraulic trim cylinder rebuilding

[billh1963]

One of my Volvo I/O trim cylinders is leaking and needs new seals. After checking around it looks like Volvo doesn't offer a rebuild kit so I've purchased a new one.

However, the parts dealer recommended I find a competent hydraulic shop to rebuild the old one and keep it as a spare. Does anyone know a shop with the capability to be creative in finding matching parts and rebuilding the trim cylinder?

I'm willing to ship it to whomever can do the job.

Thanks!

I know 5 or 6 in Toronto area... just look in the yellow pages... every hydraulics place cross references seals and such for obsolete cylinders every day....they can machine parts to take stock seals if compatible parts absolutely do not exist

If you’re playing in salt it is and iffy deal at best

The amount of labor to get it apart kills you and the shafts tend to have small groves as the SS material is a tradeoff of hardness VS corrosion resistance which is not a factor in a standard hydraulic cylinder

And then if the water spent any amount of time in the cylinder you have to deal with the damage to the cylinder wall finish as any leak will not allow the drive to stay trimmed and always be a PITA

What model drive is it?

Re: Volvo hydraulic trim cylinder rebuilding

I have a VP SX drive and has same issue. I made a spanner wrench from a piece of aluminum flat stock and two pins to get cylinder apart. Then I bought seals at hydraulic store. The shaft surface was failing (that is what hurt seals originally I am sure) so i had it stripped and hard nickle plated at local plating shop. I have about $50 total (most in $40 min plating charge). Better than the 350 dealer wanted.

It's a 290 Duoprop.

Someone on another forum said that Volo and OMC had a joint venture during that time and many of the drive parts are interchangeable? Anyone know the veracity of that?

Thanks!

Re: Volvo hydraulic trim cylinder rebuilding

The 290 is not one of the ones that was shared with OMC. It’s unique to Volvo. You have the new cylinder already so all this is academic. If you really want to rebuild the old one yourself than purchase the genuine Volvo shop manual, it will have all the info you need to rebuild the cylinder. I would think that the 290 duo-prop repair kits would still be available?? Perhaps not from Volvo but there are a few companies out there who still have NOS. If not, the seals are fairly common and the shaft can be re-plated. Good luck.

Volvo doesn't have parts or info on rebuilding the 290 cylinders. If they are bad, they get replaced.

Re: Volvo hydraulic trim cylinder rebuilding

I have the new cylinder, however, if I can rebuild the old one as a spare then that would be great. I am only replacing it because it was a litle wet (slight weep) and I am very fanatical about maintenance.

The trim cylinder looks like new, otherwise. My mechanic believes that if we can remove the cap around the piston then it's probably just a matter of replacing an o-ring.

Where is a good source for a Volvo DP-D1 manual?
We'll see!

Look on ebay,A bunch of manuals on there.
Or check with Volvo dealer...

Re: Volvo hydraulic trim cylinder rebuilding

Like I said earlier, there is no info of any kind on rebuilding those cylinders.
Nothing in the service manual. WHY you ask! Because they are not a repairable item. If they go bad, Volvo just replaces them.
Now, if you need a manual for replacing the complete cylinder, then you need Volvo service manual #7797368 and it goes for about 20 bucks from the dealer.
