Swing arm bushings or bearing replacement

My initial post was questioning what exactly is in a swing arm joint, as mine had decentigraded to the point where they were non existent.

Well a trip to the Honda dealer, and I had a rebuild kit in tow, for about $54, which was less than I found online! Love my local Honda guys, Sport Cycles Rockingham, NC!

So here is how you replace the faulty parts:
Remove rear tires, axle assembly and shock bolt. Remove swing arm bolts and take the frame to your work bench.
Now, notice you have a skinnier diameter eye and a larger eye.
The skinny eye has a roller bearing and a bushing the full witdh of the eye.
The larger eye uses a ball bearing, a large spacer collar, two smaller bushings in addition to the dust seals.
Here is what my small eye side looked like. The race is all that was left of the needle bearing. I had to heat the eye, cut the race and then it worked loose. You can drive this out from either side. Freeze the new bearing, clean the eye and lightly grease it and pound the bearing in using a 19 mm socket. Center the bearing as it has no index, then put in the dust seal on each outer side.

Now the large eye:
You can only drive out the large bearing and collar from the inner side. The eye is indexed so when placing the bearing in, followed by the collar, the bearing will bottom out on the inner part of the eye. Remove the bearing using a 19mm socket. Clean area, grease, then pound in frozen bearing and collar using a 24 mm socket.

Grease both bearings before installing the shafts.

Install and ride on!



This is my original post....
Looking to replace the swing arm bushings on my 2007 420.

One side only had a metal sleeve, nothing else to be found.....
So, can I replace it with the 2014 and newer style (looks to be all one single unit), versus the odd 4+ piece design from the 2007-2013 models? I would think a rubber bushing and steel sleeve would be all that’s needed...but anyhow.

Looking on e b a y, as partszilla doesn’t list the 2014+ bushings.

28-1211 is what I am after. I do know the bolts are the same, 12 MM.

The newer style is a pressed in rubber bushing which is intended to be non-serviceable by Honda. When they fall apart you are expected to buy a new swingarm from Honda. Manufactured that way, Honda decides how often you gotta buy a new swingarm, and a new bike... since the rest of those bikes are made chintzier as well, designed to have short, predictable product lifecycles... and Honda decides when to discontinue parts and leave you hanging. The buyers of a newer bike are converted into their corporate slaves. Their toys are all chintzy disposable landfill junk.

The old style use fully serviceable angular bearings which are much stronger and last much longer (30+ years and counting on many of the early Fourtrax bikes). You can buy those bearings and seals from every major bearing manufacturer. You can repack them with fresh grease as often as you wish.

Which design is the smarter buy supporting of your requirements and quality standards?

I have a 2011 Honda TRX420FM. My swing arm bearings needed changing. Just like in one of your pictures, there was just a shell left of the needle bearing. The new bearing (part # 91070-GC4-601 20x26x20) is what the diagram shows I needed. When the bearing came in, it seems too short. I measured the bearing and it is correct 20mm length x 26mm diameter x 20mm ID. In the pictures you posted, the needle bearing seem to me the correct length (longer than 26mm). I am not sure if the one purchased is the correct size. If I install the bearing center on the hub of the swing arm there will be plenty of space on each side, between the end of the bearing to the dust seal. Is this correct ?. It does not seem right to me. Any help would be appreciated to clear this up.
