Welcome to iboats drifter, next time you have a question and see that big red bar at the bottom, it means you need to start a new thread of your own. I moved your question to a new thread of it's own for this one.

If you in fact have a 260 V8 engine, then yes you need to pull the engine.

Find out what engine you have for sure. Volvo didn't use the 307, 305 and 350 yes, just not the 307.

If you have the charcoal gray flywheel cover that does not have a grease fitting, and uses the single PDS bearing, I'm pretty sure you do not need to pull the engine, just the tranny section of the out drive.

Not the single bearing with an AQ V8.

Not the single bearing with an AQ V8.

Sorry Don, I just edited my post with some details pertaining to the single bearing identification. I also think the flywheel cover would have had to been replaced, if this is an older boat. I didn't catch the year.

The AQ engine series (see title of thread) is red and the AQ designation on the engine ended about 87, gray didn't start until 94.

I understand that, just thinking along the way it may have been replaced.

I can't believe how much work was done to my old boat - some of it great and some of it genius. Previous owners are capable of anything it seems. LOL!

i messed up its a 305 with orange housing, the boat is an 1984 cruisers inc 24 foot, i saw the shematic on the flywheel housing and have found all the parts online everything crosses over to sierra numbers except the bearings, but they should be no trouble as long as i can gat a number off the race

Then yes, you have two bearings and need to pull the engine. and yes get the number off the bearings, they are just standard ball bearings. Nothing special.

Hey drifter,
I did this job on my 86 contessa about 5 years ago and scoured all these boards or information. I'll copy and paste the information I finally went with.

And just to be clear, I am not a pro but a do it yourselfer so do your own homework on this job. My info is from 5 years ago and maybe things have changed since then.

...just trying to give you what might be pertinent info. Good luck on the job. It's not too hard to do.

Pasted:

PDS Bearing info: Industry Standard # 6206 and #6007 "open" bearings in the equivalent of an Electric Motor grade.
No Chinese bearings!
Seals are both 35x 62x 7mm in either Timken or TCM of which are rubber encapsulated.
Pre-fill the grease cavity before installing the seals.
Glue or stake the forward seal in place so that grease pressure cannot blow it out of position.
Be sure to install the aft-most seal in the non-conventional orientation.

To pull the engine on your setup, just remove the upper gear box on the drive. No need to remove the complete drive.



Once you have the upper gear box off, remove the 6 bolts holding the clamp ring in and remove the clamp ring.




Then just disconnect the electrical, cables, hoses, exhaust, and lag bolts holding front mounts to the stringers and lift the engine forward and up to get it out.

Don,
Could he also separate the flywheel cover from the engine, leaving it attached to the transom? That would save him the cost of those two gaskets, right?

Re: Primary Shaft service info needed. AQ-280 out drive/ AQ-260 motor

You don't have to replace those big rubber rings unless they are really, really flat or damaged.
I have reused them for many years with no problems, think I only replaced them on 2 or 3 boats (PS: Volvo certified tech for 15 years and I have pulled hundreds of engines)

Re: Primary Shaft service info needed. AQ-280 out drive/ AQ-260 motor

You could probably do it that way, but man would that take a lot of climbing in and out of the boat. To say nothing of trying to get under the engine to get the tin off and the flywheel cover bolts out.

thanks it doesnt look to bad, just more time consuming than anything else. this is the first failure on my 84 cruisers so i cant say a bad thing about volvo
