I got my Motion Pro swingarm tool yesterday and decided to replace all the bearings in my linkage. I was surprised how easy this job was with the right tool
The tool cost me $54 including postage from eBay.
The kit comprises of a threaded rod and nuts , 3 different size drivers , a thrust bearing and 2 washers
To use you simply remove the bearing seal and metal insert
Select the right size driver for your bearing
Place into the bearing
Insert threaded rod , thrust bearing , and I used a 30mm socket to push the bearings into
Use a socket to tighten the nut
Tighten until the driver pushes the bearings through into the 30mm sockets
Bearings out
To fit the new bearing , slide it over the correct size driver
Assemble the Motion pro tool as before , ensure the bearing is seated correctly
Drive the new bearing into place by tightening as before
Turn the over and repeat for the second bearing , grease , fit insert and seals
I’m not a mechanic but I found this very a simple job and took about 30 minutes to replace all the brearings and seals in this linkage. I know their are ways to do this with sockets etc but this tool worked very well and I thought well priced too.

The Crf is the same mate , one end of the link has a lip that the bearing sits on. I have been told to take out the needle bearings then put some heat on it ( apparently aluminum expands 3 times more than steel ) then tap it out from the opposite side. Then use the tool to press in the new bearing . I’ll let you know how this goes Buzz !!

Update for Buzz
I ended up putting the link into my vice and heated it with a heat gun , I didn’t like the feel of knocking out the bearing case with a punch so I found out that a blind bearing removal tool fitted perfectly through the opposite side of the link and once expanded sat nicely on the bearing case and it tapped out easily.

This thing looks pretty handy. I used the press at work when I did mine. But that dragged me away from home using up precious brownie points.
This looks like something I could keep in my home tool box. Thanks for posting. BTW I was talking to Buzz re this today and he asked if his old hair dryer would do to heat up linkages and the like. I couldn’t see why not just as long as he held it there long enough. :whistle:Aaron wrote:This thing looks pretty handy. I used the press at work when I did mine.

While the steel bearing won’t expend as fast it can and does expand. A heat gun heats faster minimising the heat transfer into the bearing

Thanks TB. I could see how that would be as we put a graphics kit on a bike and tried a heat gun in a few spots but it was a bit vicious.
I have seen the fitters put some bearings in the over night fridge also before an install.
