Volvo Trim Cylinders

[garagenc]

I started tearing the outdrive apart to get remove the trim/hyd cylinders for repair/replacement of the o rings and seals.

Right off the bat one of my removal bolts for the helmet plug broke off and I tried to use a extractor, didn't work had to drill the broken bolt out and then use 2 punches to remove the plug.

What should have been a 5 minute job ending up taking 3 hours.
Removed the top portion of the outdrive (no Problems) removed the shift cable and raised the outdrive up until it was straight out from the transom.

Tomorrow when I get in from work I'm planning to remove the hyd lines to the cylinders and then see if I can disassemble the cyl in place or if I have to remove them from the transom shield. The bolts that hold the cyl to the transom shield are in the lower portion of the transom and it looks like I'll have to remove the exhaust manifolds to get to the bolt pins that hold the hyd cyl to the transom.

I found a guy on e bay that I think has the repair kits with all the o rings and seals.

I'll try to take pics and post them on here as the job progress's unless no one is interested then I'll just "geter done" without a report and pics.

Lee, wish I had some advise for you, but I've never done one of those. Good luck with it, keep the heat handy, you'll probably need it

Hit a snag:

I got a e mail from the guy on ebay and he said he doesn't have any repair kits to fit my cyl's.

He said he's never tried to find the kits for my stuff.

Now the decision comes to try to get mine apart and see if I can find the seals and o rings or bite the bullett and buy cyl's.

I wonder if the newer style cyl that he has would fit mine?

Took some pics of additional disassembly but I'm having trouble with login for photobucket so until they get my login fixed I wont be able to post pics.

I could open a new account but then I would lose all my pics stored on there. It may come to that.

1 of the pics I took shows a plastic allen head fastener (outdrive side) next to the hyd cyl pin that holds the hyd cyl (trim hyd cylinders) to the transom shield.

Does anyone know what it's for?

Also the hyd cly pin is threaded partially and has a bolt in it (is inside the boat) does anyone know how these pins are removed?

The Seloc book doesn't address my type of attachment.

thats a 290 drive right? I'll see if i can get a factory manual

[garagenc]

Yea a 290 DP 1.95 1991

Thanks Lee

Lee, If you can get the cylinder head, rod and piston assembly out of the cylinder barrel you can take it to Hydraulic Service on Victory Blvd in Portsmouth Va. Im pretty sure they could fix you up with a repair kit. Give them a call at 757-487-2513 or toll free at 1-800-537-9986. I use to carry all kinds of cylinders to them and they have always fixed me up.

Thanks C

If Tony at Shoreflythe is correct the only way to get the connecting pins (that hold the cyl to the transom shield) is to push them outboard with high pressure grease. If you look at the 2 pics that show the yellow dots, they get removed and then the grease fittings are exposed.

He said they could be very hard to get out.

Tony said he had found o rings and seals to fit them but he didn't sound like he would sell them to me or install them in mine ( I think he wants to do the removal and reinstallation)

If I can get them out I was planning to go to a hyd shop and try to find the o rings and seals but I may see if Tony will sell them to me.

Spare was looking to see if he could find a manual on mine. My Seloc repair manual doesn't address my type of connection.

You can try ta soak those pins down with PB Blaster or penetrating oil if you can get it on them, it may help. I've never messed with a Volvo Penta drive, I ain't much help. They look like they are a pain ta get off.
