Oil drain plug size

<< < (2/3) > >>

Nurse Julie:
I'm a bit confused (easily achievable). Have you not just stripped and rebuilt the engine? Did you fully clean the sump pan by removing oil separation plate? If it's the wrong sump bolt, which makes sense as there shouldn't be a dowty washer there anyway, did you not notice any damage / repair / bodge around the area?

Haha of course I noticed it. But pay attention, and check against other engines? No.  ::) The sump has had a repair, it's been welded and I did a small amount of smoothing before I sent it off for cleaning. But the threads looked good and I assumed it wasn't leaking, as there wasn't a pool of oil on the garage floor before I took it all apart.

The bolt I have is about a 22mm (from memory) head, the thread looks to be about 15mm (I measured this so I could get a copper washer that might fit from the local fastenings place).

Bottom line is that I will have to get an unbuggered sump for the girl when I can prove it runs.

Laverda Dave:
DSS has replica sump pans for £95+VAT+post and you'll need the bolt and washer (he sells those as well).

mike the bike:
It's 17mm.

Sprocket:
So the head is 24mm, and quite clearly you can see the crack (now it's wet!) the PO has fixed. The sump doesn't leak, the reason this is soggy is because I undid it to measure the size of the thread. I think I'll keep as-is now and get a replacement sump in time for the first oil change.
