Trying to remove the swingarm axle bolt. The nut is off, the axle wont budge. Is there something else that is clamping the bolt or does it just need more brute force?
cheers J

Probably rusted into the bush ( that the needle rollers run on ) on the left side . I had to beat mine out with the log splitter ( BF hammer ). I laid the whole bike on its side and supported frame around the pivot bolt hole ( with lumps of firewood ). Put heaps of CRC WD40 around it for a day or so and have a go. Try not to damage the pivot bolt ..... I used an axle bolt out of something as a long drift. If you try to rotate the pivot bolt it will spin easily as its spinning the bush as well , so that really only leaves you with beating the shit out of it.

You got your swing arm out yet Fraser ?

Hamish,

New swing arm installed, new WOF, even rode it into work this morning. Need to get some exercise on it before the Boxing day races at Wanganui.
Cheers,

Fraser.

This pic shows the needle rollers and the bush on the left side of the swing arm

This pic is the ball bearings and spacers on the right side of the swing arm . It could also be rusted into this spacer/bush . The bush and bearings on the right side are what locates the arm end float (side to side on the bike ) and the needle rollers on the left just sorta sit where ever they need to .

Nice pics. Don't forget the silly little set screw that holds that aluminum spacer in place.
I have mine apart on the bench currently also. Sure is an expensive way to make a pivot (one of the reasons the Paso line went out of production) Later models, like the ST, were much simpler, cheaper, and easier to fix/repair.

Cheers, Phil

early designs rely on whats available in the parts chain. It takes time to develop a new supply of parts to improve on the concept as new tooling is both expensive and time intensive

Best wishes for 2016 to all.
Thanks for the info and pics. I got the bolt out with a bigger hammer.
I was going to renew some of the bearings to reduce the free-play but I think I will be looking for a Alu-welder now.
The PO probably never ajusted the chain tension. The chain has chewed through the swingarm on the bottom side, all the way to the rollers and ground out a weld on the top side. Anyone got a good swingarm going?
Cheers J

looks like this;

Mine was similar , just not ground right thru to the bearing .I think the swing arm in my pic was the one I sent to Fraser ( which was dumb coz its better than the one on my Paso ) I just made a new chain slider that went right round the pivot , just a 30mm wide strip of nylon strap 5mm thick , heated up and bent round the swing arm and pop rivoted on ................then I found some new Ducati chain sliders.
Beats me , if you run the chain anything like slack enough to do such damage the gear changes are real bad and that alone would make me want to tension the chain properly ...............but then I have heard of people blissfully riding round with their sprocket bolts cutting their swing arm in half ...........not looking towards anyone in particular

I took the swingarm out with the intention to cure the play on the lever system.
After cleaning and checking I put it back together to see which of the needle bearings/bushings needed replacing. What did I find, no play at all. Conclusion, the play I felt before was not in the bearings but the bolts through the bearings. These need to be very tight to prevent movement of the bushing on the bolt. Clamping force needs to keep the bushing in place. I have checked this on 2 other 907's, same issue, one also cured by tightning the bolts, (I own 2, the other was at a dealer)
My tip, put the bike on the centre stand, grab the end of the swingarm and pull up. If there is about a cm of free movement you probably have the same issue, tighten all the bolts and the ride quality will improve a lot.
What I also found on all three 907's I checked, the rear shock didnt work.. The two I checked had zero pressure where they need 6 or 7 bar in the canister. Pumped then up and found another huge improvement in ride. Only problem now is that they loose pressure over time. Anyone know the cure for that?

Happier with the 907's every day.
Cheers J
