DR650 gearbox whine

**XF650** · 21st July 2009, 10:46

The bit of metal has been ID'd as being the the tip off a circlip end. Advice this morning is that the circlips used in assembly aren't good quality and that impact from crashing gears could damage them. Apart from this one piece the oil is very clean - good enough to use in the lawnmower anyway.
In the meantime I'm fitting a magnetic sump bung, scrounged from a wrecked Suzuki LTF (quad) - it's the same size as DR/XF, see pic

I bought 50 neomidium high strength magnets (only wanted 3) to make some bungs.

If it's only the tip then the only problem may just be difficulty in removing it off the shaft later.

Manual shows 4 circlips in gear cluster & 1 on the balance shaft. Service caution states never to re-use circlips.

I carry 2 spare circlips for my front sprocket.
Seeing how much they deformed putting them on, there's no way the old ones'll be getting re-used.

Back in the day, I was puttin my IT back together the night before a hare scramble , and lost the wire circlips from the piston. I tore the shed apart, and could not find them anywhere, but did find some normal inside circlips with the eyes in them. Got the bike going that night and finished the race the next day, although the bike had lost a lot of power.

Anyway to cut a long story short, all 4 of the eyelets had broken off and caused a lot of damage to the piston and bore.
Not sure if there is a moral to this or anything, but it did bring back some memories.

Drill a 6.5mm hole about 4mm or so deep and drop it in there.
You could use a flat ended drill bit to give a nice flat face for the magnet to grip and it would not come out unless grabbed by a pair of pliers.
Or just a bit of JB Weld.

If the magnet is pulled out then it's a bigger bit of steel than the sump bung so you'd probably be having other issues

Put me down for one too please Nordie. Pretty sure my bung is non magnitised as well (ohh err

)

Cheers R

There's only a few magnets left so hurry up!

That's 300g of 10mm thick steel hanging from the magnet.

**pete376403** · 22nd July 2009, 20:21

I'd like one if available, please.

Can I book one too?
And a query about your first photo with the magnets neatly stacked on top of each other - I thought a magnet repelled another magnet?

Not if they're stacked North-South-North-South-North-South...

If you try stacking one North-North it bounces a fair distance or just flips over violently.
