Is my outdrive scrap?

[lewlew100]

Thanks OG MURV and BOUBA. I guess that the reason this old thread being re-awakened was due to OG trying to help me with my Jackshaft (PDS) problems. Having FOUND AN EXPLODED DIAGRAM OF THE AD40 on the web I am fairly certain that the engine will have to be removed. Due to not having any room in front of the engine I am looking into trying to separate the engine at the rear of the bellhousing - IF I can find someone to do it. Geoff.

Although it may appear to be a rather daunting task.it is not that complicated.
Just need to be methodical.
In my case the engine was only moved forward the few inches to get at the bolts with spanners/sockets and this was done using a very Heath Robinson scaffolding tripod affair with a block and tackle.
Being an idle git did not undo a vast amount of stuff by way of of wiring/fuel pipes,perhaps with the exception of the starter motor cables and of course the front engine mountings.
Replacement bearings all came from a generic bearing outfit. The entire affair took about a day to remove leg,shift engine take jackshaft out clean everything up and another day to bolt everthing back together.
A more sensible person would have taken more time to do the job but after all the the other leg problems preventing use of boat,was keen to get back into the water.
Why on earth a couple of grease point was not designed in to the transom assembly is known only to whichever particular God you believe in and Volvo.

Thanks OG, that sounds very reassuring. From what I have read on an American forum, there is a grease point, but in such an awkward position that it tends to get forgotten. One American dealer referred to ZERKS? which I assume is a grease nipple and stated that on any boat that he deals with he extends the GN up to a position on the transom with easy access. If I am unable to find a willing engineer I will try to get some sort of lifting tackle arranged and have a go. Thanks again. Geoff.

Def no grease point on my transom casting.
Even considered drilling something and installing a nipple to get grease into the void between the inner and outer bearings.

As I understood the comment, I got the impression that the greaser was on the jackshaft housing extension, but that may of course just been my interpretation. I suppose that as it was an American site he may have been referring to petrol engines. When you moved your engine back a few inches did you split at the engine end of the bellhousing or the flywheel cover? I think they are two separate parts. Thanks. Geoff.

Ususally if the bellows have had water in for some time the input shaft rusts and knackers the seal on the top section allowing water into the drive, Vp drives tolerate water better than others, so a good rinse with diesel and new oil usually is all thats required. But also check the seals on the propshaft and gearshift nmechanism.

thanks spannerman
my feeling is that with a clean and new seals it's going to be ok-any advice re changing the propshaft seals? It looks on the exploded view to be a straightforward remove two bolts, extract shaft/bearing/seal assy....

Yes its pretty much as you describe, just be careful when refitting the bearing housing over the prop shaft as the splines can damage the new seals. I usually put a plastic bag over the shaft as a kind of condom and slide the bearing housing over then pull the bag off the shaft.
