Although it's midsummer here.
Now you may remember a few months ago, probably a year or more actually, I had a 1200 Sport 8V in that had a faulty oil pump gear that was full of voids and which had stripped its teeth off? Luckily I caught that and no damage was done but while we had the front off it replacing the gear with the earlier steel version we found this!
Now why the inside of the timing chest should be painted at all is a question you'll have to ask whichever Piaggio wonk thought it was a good idea but I thought that it's peeling and flaking like that was most likely a preparation issue rather than a paint issue entirely. Anyway we dropped the sump and cleaned all the strainers on the pick ups and got the inside of the timing chest blasted before we reassembled it so it was all good. After all it's not something I'd seen before or since........
A few months ago I rollerised another Sport belonging to a bloke who lives out west, Orange I think from memory. As part of the process I would of dropped the sump for a decent clean out and there was certainly nothing that looked like loose sheets of paint drifting around and the strainers were clean. Just before Christmas though I got the call. It had blown up spectacularly while he was giving it a bit of a hurry-up. Dropping the sump revealed lots of big end frag but he then left it until Christmas/New Year was over to explore further.
Yesterday he sent me some pics. Have a look at 'em. You can see the culprit as clear as the nose on your face.....
This one really tells a tale.....
Most of this crap is bits of big-end shell but you can also see the sheets of paint.
Thing is BOTH
of these Sports are red, pre ABS, machines from memory and I'll put my one remaining swinger on them being from the same batch run of bikes. Whether the oil starvation is purely down to the strainer on the pick up for the lubrication circuit being blocked by paint or whether I'll find that the oil pump gear is faulty as well I won't know until we open up the timing chest.
It is most vexing.
