can't get it fixed

[Brutus]

Can't get the linkage-arm of the swingarm in the frame. It's part 29 in the parts-catalog. The drawing shows that the arm has to be fitted with two washers. That's the problem. I can get the first washer in, the second one is impossible without extreme force! Anyone fitted the arm without the washers?

The washers (28) were not on my bike when I removed the swingarm linkage and when putting everything together I didn`t put any.
Did you have the washers on your bike when you removed the linkage ?
I was wondering if that is in fact another mistake in the parts catalogue as even part (30) does not exist.

If I remember correctly, i didn't have washers in that location, either. I did have a washer (#28) on either side of the pivot bolt where it mounts to the swingarm. The washer went between the connecting rod of the linkage and the block section of the swingarm where the linkage bolts to it.

In this picture, the washers go between the block on the bottom of the swingarm (the swingarm is upside-down in the picture) and the connecting rods of the linkage that are not attached to the rocker part of the linkage....




On a side not - Both of my bikes that had the washers installed in this location and not in the location you are speaking of, had been apart by previous owners. Do you specifically remember removing the washers from that location?

Tx guys. Got it installed. I've bought my paso in parts and I'm depending on the manual. So far I've located several mistakes in drawings.. So much for reliability..

Hi,
Just seen this thread. When I removed the rear suspension linkage from my 750 (owned by me since new, so as it was put together by the factory) I only had 1 shim/washer between the linkage and the frame brackets, on the near (left) side. I could see where the linkage had been rubbing against the frame bracket on the other side, which accounted for the occasional squeaking from the rear supension.

I assumed that the fixing (welding?) of the brackets to the frame wasn't very accurate so when the bike was built they could only get one shim in so left the second one out. The shim was 0.042" thick, or about 1mm, I could also fit a 0.010" feeler in so I had my father make two 0.025" shims (26mm OD, 7mm ID) on his lathe to take up the space, placing one on either side of the linkage.

have checked the parts catalogue with my dealer today as his PC version (of 907ie) shows more details then the printed one. The washers exist as 1mm and 0,5mm and are indeed used for shimming if necessary.

PS: interesting that the arrangement of these washers at the center linkage mount of the swingarm is different on 750 and 907ie

after checking my own swingarm linkage, the spare one and my 907ie swingarm again I noticed that if you rebuild or change the swingarm you`ll also have to check the clearance of the connecting rods to the distance piece (hollow axle) at the swingarm mount. This gap varied on my parts from 0,8 to 2mm !
Strange enough the 907ie parts catalogue does not show shims here but they may be required also.
For the guys having rebuild or switched swingarms lately, better check.
Good hardware stores sell shims in 0,1mm steps (should be M10 I think).
