Help Assembling Volvo Penta DP Outdrive

[cchinny]

Hi, I bought a 1991 Larson 220 Hampton that the outdrive DP 290 (I think) was taken apart because of a broken steering helmet. I think the shop removed the driveshaft from the lower unit and put it back on without screws or other parts. When I put it back together I wound up with these "extra" parts. One looks like a home made wood shim and the second a big plastic ring that I have left over. If anyone knows where the ring goes and which way the white side faces that would be fantastic. I want to make sure I put everything back in place before I put it in the water. Also, how important is it to replace all the rubber seals? Any pointers on putting this back together. If anyone can help I would really appreciate it.

Chinney,

In attempts to fix the photo issues, try this. Go to photobucket, create an account, upload pics there, after uploading and viewing a photo you should see some links with code on the side of the photo. Copy the html version and paste it here in the post box and click reply and see if your photos show up.

Good luck

The only plastic ring I've seen on a DP is the one under the cone securing the smaller aft prop.

I think it worked now with the pics. Again any help appreciated.

I don't know anything about this drive, but extra parts are never good. Wood shims?? Not replacing rubber seals? If the drive leaks, water will mix with the gear/motor oil within the drive and failure is only a few minutes away.

The manual for your drive may help. You can find it here: http://boatinfo.no/lib/volvo/manuals..._drive.html#/0

Before putting in the water, I would make sure and pressure test the drive.

So, it is hard to tell from the manual what parts I have. If I had taken it apart myself this would be a different story. Is it possible the black O-ring is the shoulder washer that goes over the Ujoint drive shaft? I have no idea where the wood shim came from. That was sitting in a box in the boat. I'll replace the seals or pressure test it before putting it in the water.

Anybody know where the black ring goes? One side is black the other is white and black.

Anybody? Someone has to have taken apart a DP outdrive and recognize where the ring goes? it is possible that it is the inner or outer thrust ring for the propeller? I'd like to get the boat in the water this weekend. Please help!!!

Okay, I'll take a stab - First thing: You think you have a 290 DP, and the pictures show that but, there are different variants of that drive. Check the data plate on the upper gear unit to determine which one you have. I used to be able to post pictures but this site's new format appears to have screwed that up. Discussion below relates to a 1989/1990 DP-A SN# 3102070596 There wouldn't be any reason for a shop to disassemble the lower unit for a broken steering helmet, so lets assume the lower unit wasn't touched. There are no wood shims anywhere on a 290 DP - there is a "cork" ring listed as item #32 on the DP-A parts breakdown for the upper gear unit - Does your wood shim appear to be a ring?. On your 3rd & 4th pictures, there is supposed to be only a shim (if required) & an o-ring between the intermediate & upper gear units (for a DP-A), what you've got pictured (rubber/Teflon) isn't either. Hold the plastic ring you have in the 2nd picture around the upper unit flange where the drive bellows is clamped. Does the radius of that ring match and does the ring have a "V" notch on the outer circumference? If the answer is yes - I've heard that some DP drives have something like that glued/bonded on the upper unit to ensure the bellows stays secured properly when clamped.

Great thank you!
