Let’s do some rear maintenance (to the extent we can).
By the way, you can pretty much assume that nearly all the parts around the swing arm link on this GSX-R750 GR71 are shot (；∀；)
We use a frame stand to lift the rear.
Frames with an undertube are extremely effective for this.
I wish they’d sell this commercially already……
We start taking things apart.
The neutral switch has wiring coming out like I’ve never seen before—did the original spec have a gear position indicator?
We’ll use the cleaner rear suspension that you brought in (‘ω’)ノ
We measure just the SPG set length.
For its year, the condition was pretty good. The swing arm scratches were there from the start.
Unfortunately, the bearings you brought in are completely wrong.
Good thing we didn’t remove them~
Since these are all standard parts, please look up the part numbers.
It’s best not to use a slide hammer for swing arm bearing replacement. Not only does it look rough, but there’s a high chance you’ll destroy the bearing and leave just the outer shell behind.
With a hydraulic punch, you can even use it as a puller.
You do need to make the drift on a lathe, but it lets you remove things very smoothly.
And of course, insertion is equally smooth (^_-)-☆
Working in a straightforward, recipe-like manner reduces mistakes.
Aluminum and anodized products actually respond surprisingly well to carburetor cleaner.
Spray it on and scrub with a soft Scotch pad, and—surprise!—you get a surprisingly clean finish.
*The photo shows engine conditioner, but it works about the same.* *Don’t use this on painted items.*
Since I’m not sure what the original condition was, I can’t say for certain, but it works really well—give it a try sometime.
That’s all for now~(*^-^*)
