Here is a pic of the Volvo drives and their oil requirements, it’s a long diagram but took oic of maybe what you have, I know some of the early 280 drives say use 30wt oil, I have always run 75/90 in those just not synthetic 75/90, on all my dp drives the synthetic 75/90 will get pic of the oil can tomorrow for you

Have to spend some time going through the silhouettes to look for features which match my sterndrive. Have you heard back from your mechanic regarding the dark coating on the clutch seats? Also, does anyone have an idea why the main shaft moves up when I turn the universal bearing anti-clockwise (see pictures)? Thank you Martin |
I know A and B series have a metal bracket that the power trim rams mount to on the drive, I think c,d,e series the rams mount directly on the drive., I will try and take closer up pics of the drive diagrams, unfortunately too large to scan and email

This is some close ups of drives, it does not show dpe but its is the same as the D and uses vp gl5 75/90, the earlier models show gl4 90, not sure Volvo makes that anymore, check your Volvo dealer. Sorry my guy is out and have not had a chance to speak with him

Thank you for the feedback!
To prevent me from causing further damage I kept reading before lapping. In one of the articles it was said that Volvo experimented during the production time of the DP drives. Apparently the steel sleeve and the steel cups must not be lapped. Only the ones where one of the two is made out of brass shall be lapped - which sounds logical. Furthermore the article also mentioned Volvo added some sort of anti friction coating to the cups. These shall also not be lapped - which also sounds logical. Now, the configuation I had when I opened my drive was steel sleeve, steel cups, some sort of sticky layer on the cups only. I am wondering now if I have the combination of factory fit steel sleeve, steele cups AND friction coating. Unfortunately I am unsure what my sterndrive seriel number was as it was corroded away. Maybe someone of you guys has the ability to check what the factory fit shifting cobination of my drive is? https://cimg0.ibsrv.net/gimg/www.off...77cdecd9a5.jpg I have no idea what was replaced during the first 30 years of useage before I got the drive. Also I am wondering if my issue was linked to the oil I used. According to the information I had at the time my drive needed GL5. So I used Ravenol SAE 90 GL5 oil. I know not the recommended Volvo Penta oil but I didn't know any better back then since it is my first boat. As it is a but of a pain to get to the clutch sleeve, I would like to get the confidence that the internals are as intended before putting it back together and try it with the Volvo Penta oil. Technically I have three options now. Option 1: use a new brass sleeve and lap Option 2: use a new steel sleeve and lap Option 3: use the old steel sleeve and try again with the Volvo Penta oil Sorry for the big confusion. I think finding out what the factory fit configration was is the best starting point. Thank you Martin |
Do you have a picture of the complete drive, at least we could narrow it down a little to the model, sorry but it’s getting a little too technical for me, do you not have a vp mechanic near you, also perhaps look for a good used top box, as gear ratio is in the lower unit, that’s one of the nice things about Volvo penta is a lot of interchangeable with their drives.
|
When it comes to the top box their are too types early models had a smaller top bearing and laters models had a larger top bearing, I have a dpe and have a dpx top box, I am referring the upper section when I say top box as the drives have the lower section, mid section and upper or top box. Do your power trim rams mount to the mid section directly to the drive or is there a large stainless steel bracket that they attach to.. if you have the big stainless bracket that the rams attach to it’s most likely an A or B model.send pic, and I know a lot of guys like to rebuild their own stuff but sometimes it’s good to take to a mechanic, it’s not like a car that you fix yourself and it breaks down 2 miles down the road, just pull over and fix or call. Tow truck, the boat breaks down and you maybe heading for the rocks on a beach.

Hi
Here are three older pictures. One from the previous owner and two while I was cleaning it after the purchase. https://cimg8.ibsrv.net/gimg/www.off...a3f41f495a.jpg https://cimg4.ibsrv.net/gimg/www.off...d9299b424.jpeg https://cimg3.ibsrv.net/gimg/www.off...d0b1bbddb.jpeg |
