I have just drained oil from v50 following manual, then removed oil filter cover, before i put the new filter in a hexagonal threaded bit fell out of the old oil filter, the screw that holds the cover on to the sump screws in to this other bit but it doesnt appear in any exploded drawings anywhere, what is it and how does it hold the filter cover in place ? it has tightened up ok but just puzzled as to what the `piece` locates on, hope this makes sense..

Not quite – a picture would help.

The oil filter cover is the little nearly circular finned alloy bit right? It seals to the rest of the sump with an O ring. And there is a single long retaining bolt that runs through the centre of this cover, up through the length of the oil filter, and then … I always presumed ... screws into the underside of the block somewhere.

Which leaves me unsure as to what the piece is that you have found. My money is on it having come from somewhere else and that the filter had done its job.

The hexagonal piece was /is about 2" long and must be what the screw that holds the plate on screws onto... I haven`t filled it with oil yet so i will take it off again tomorrow and take a photo,  thanks

ps, the cover is a secure fit...

took it off again, it seems as if the screw goes into the flat end and then the wholle of the hex piece goes into the filter and then screws up into a locating hole (threaded) in the sump,  seems to work..

Thanks, seems it is called a `union`    question is now... should it be loose ?

If screw 32 screws into the end of it, I would say, no.

It seems the action of tightening screw( 32) turns the union (8) and they both tighten together,    thanks again..

As 8 has flats on it, I would assume it is supposed to be tightened into the crankcase with a spanner, then the screw holding the filter just screws into is. They could have just fitted a longer screw, but that would mean screwing into alloy every time, not best practice.

sorted, that is how it works, used a long extension to locate the union then oil filter screws on as normal,   just need to fill with oil now,  many thanks to all..

Wow – I’ve never seen that parts diag before, nor realised that the piece 8 even existed. What do we thing the hole drilled into the flat might be used for? In the picture we can see that the thread is much finer on the filter retaining bolt than on part 8. I can’t really therefore understand what the bolt 32 is actually screwing in to right now. 

I’d drop the sump at this point to have a good look up there. Assuming threads are mostly good I’d make sure that 32 winds nicely into 8 before cleaning up and locktiting 8 back in. Occasional removal of the sump and cleaning of the gauze filter in there (but which I can’t see on the diag) is recommended anyway, though in my experience has always been a waste of time. If the sump hasn’t been off before then you’ll likely have an unhappy time having to scrape the old gasket off the faces before fitting a new one – and which I would oil before fitting.

It would be normal practice to use a coarse thread into alloy and a fine thread into steel which accounts for the differences.
The bolt screws into the female thread in the other end of part 8 which you can't see in the photo.
So part 8 should be properly tightened into the alloy casting, and shouldn't come loose later.
I suspect someone has tightened the bolt up too hard in the past. It only needs to be tightened enough to compress the seals.

Hi Butch.

I have a pdf of the parts book that includes the diagram - I've found it very useful. If you want a copy it's at http://www.iansoady.org.uk/pdf%20documents/parts%20book01.zip.
