removed the rear rocker arm to frame (after removing rear shock & control arm); carefully put components aside bolted back together off frame ... went to put it all back together again and

read and re- read the mec shop manual section on rocker arm to frame connection; I have 2 washers through bolt and nut (and the inner roller bearing components inner long spacer and seals have not been removed from inside rocker arm); ... seemed to be simple, straight forward, when I took it apart but now something doesn't seem right ... :P

question is; do the 2 washers go on the outside of the frame? or is one or both washers go as spacers between frame and rocker arm; cause there's a fair amount of side to side slide in the rocker arm as it sits without, about 1 mm; but neither of the 2 washers (both different sizes) do not seem to fit on the inboard side between frame & rocker arm; and its so unclear in the mec shop man and parts manual, where they should be located ... but maybe the thinner of the 2 belongs between frame & rocker arm ...? but does not seem to fit ....( fun?!) [popcorn]

Could someone please confirm where the rocker arms go and how much side to side there should be on the rear rocker arm?

Washers on either side against the frame, on the outside.  The special one on the right faces a particular way.  There will be some side-side play until you torque it down to spec.

Manual has this to say for my '07, FWIW:

Refitting the rear suspension
Grease shank and thread of the screw (10) and the contact faces of the washer (9) with specified grease.
Grease shank and thread of pivot bolt and the underside of nut (16) with specified grease.
Insert the complete rocker arm between the frame supports, as shown in the figure.
Fit the washer (9) to the screw (10) with the concave side facing the screw. Insert the screw fully home into the
frame.
Install the nut (16) with the hexagon facing outward and with the spacer (14).
Tighten the nut (16) and tighten the screw (10) to the specified torque (Sect. C 3, Frame torque settings).

Thanks!  [thumbsup]

Your instructions seem clearer that the mec shop man I have ..."go figure-iro Italian-o translation-io"

ok seems to make sense; but that's a fair amount of flex to get that to close the gap ... but I do see a fair amount of torque; "75 nm" or more understandable imperial 55 ft lbs If I remember ... will double check ... its a critical point... to avoid serious ball busting from a number of  perspectives the more I think about it ...

ha! was amazed after torqueing to the spec 55 lbs; -no play! took up 1-2 mm of play; that's a fair amount of flex in the frame with a whole bunch of welding and gusseted reinforcement in that area

- thanks again-  [Dolph]
