Swing arm 'spacers'?
Posted: Tue Feb 21, 2023 7:22 pm
Hi all,
I was performing some different service work on my 2013 R12RT. This required the removal of the swing arm. I followed a Haynes manual (for RT's up to 2009). Additionally, I thought I took enough pics of the teardown..... But upon reinstall / reassembly of the subframe, swing arm, rear shock, and final drive I was left with what I believe are a couple of spacers or washers or dust protectors.
The only place I can think of they came from is between the subframe and the swing arm pivot points as the inner holes on the spacers 'appear' to be the same diameter as the both pivot pins in the swing arm (going by memory as I'm not taking it apart to confirm) and there appears to be the narrowest of gaps that these spacers could have filled in after I did the reinstall (preloaded and torqued to spec). I can get pics and dimensions if need be to show. I just don't recall them falling out when I removed the swing arm.
Manual doesn't reference these spacers at all. OEM fiche shows no washers in swing arm or rear frame diagrams.
One spacer/washer has about a 12/13mm inner diameter, about 30mm outer, is very thin, (less that a mm thick?), and appears to be plastic. The other, similar inner diameter, only about 20mm outer, 2mm thick, and appears to be neoprene or rubbery foamy material.
Any thoughts anybody? Couple queries:
1) Something added to later models RTs; 2010 to 2013.
2) If they are as I suspect; spacers and/or dust protectors for the swing arm/frame gap, are they critical?
3) If not for the swing arm, any thoughts where?
Anybody done a swing arm removal on a similar year RT care to comment?
Thanks.
