Hi all, I'm prepping my swingarm for powder coat, and as this is my first time at any of this, wondering how I get these shock mount bushes and front bushes out of this thing? Hammer time?
-
Mr T,
On the shocker bushes I use a socket slightly bigger than the hole with a threaded bar nut and a washer and just screw them out. If you youtube it you will see how to do it.
Watch out for the tapered edge when you are reinstalling and it is just the reverse process.
On the swing arm bushes I did mine with a blind bush/bearing puller but you can drift them out be careful with the bronze type. If you are putting new in as I did then it doesn't really matter how you get them out.
Regards,

some photos for shocker bush removal here T: http://www.sohc.co.uk/index.php/topic,4120.90.html

Both can be a little tricky IF they've been in a long time.
Shock bushes, using a socket normally works, however they can sometimes be sort of bonded into position and the socket will just cut through the rubber bush leaving the outer metal casing behind. If that happens a junior hacksaw can be used to cut a line in the casing until the swinging arm is met, the casing will then contract and is easy to remove.
The inner steel part on the swinging arm bush in the pic is removable, pull that out and your left with 2 sort of hard nylon bushes, same hacksaw trick can be used and they can tend to break up if you try and push them out with a long screwdriver or similar from the other side. I tended to use the hacksaw trick and it was quite easy to cut through, Honda do a nice little bearing puller for the CB1300 but at around £50 to buy it's not really a good investment unless you plan to use it a lot. I'm sure there are bearing pullers very similar for a lot less, depends if your on a budget and just want to get them out on the cheap.
Oddjob, how do I remove the inner steel piece in the swingarm bush pic? Sorry for such basic questions... feeling pretty new here.
-
You remove the pressed in bush by using a hacksaw blade. Cut down the bush until through, then cut another 10 mm away from the first. The 10mm bit of bush should come out by lifting it with a small screw driver. The rest of the bush will be easier to fold in on it self.
Just looked at the picture and this bush looks thicker than the standard type.

Did one earlier today and had a hunt in the bin. This is how you cut them
-
And the new ones look like this

Bloody hell Trig your going out of your way to post pics now. ;D

Trig did you freeze the new ones before fitting I do.Am I imagining it or did someone on here say soak the bronze bushes in oil first.
Mick

Thanks Trigger! Where do you source your new brass bushes?

I've also heard about the soaking in oil bit. Worth it?

Frank in Germany. No one can beat his price and quality.

My work shop is freezing at the moment. I just put two block of wood each side and place it in the press.

I have known Frank for years. Met him when i lived in Germany. Good old boy ;D

Yes, soak them in oil overnight, phosphour bronze is porous and will absorb oil, always a good way to start their working life. Lucas and various others use p/ bronze for bearings/bushes on starter motors, and they always pre soak in oil before fitting, and remember how long they last without any further lubrication:))
-
Oh well I'm sure mine will be fine I grease them every 1000 mile or so.
Mick
-
This what i did as you tighten the nut it pushes the small socket against the bush and out through the large socket

The swingarm ones need a bit of heat and are buggers to get out
pete

Yup Agreed

Just wanted to let you all know that the socket press idea worked a treat on the shock bushes, and the swingarm bushed came out slick with a bit of heat and a few taps from a drift. Another part ready for powder coat.

Anything else I should grab from Frank while I'm at it to save on shipping?
-
It all depends on what bits you're going to need in the course of your resto that spring to mind, head bearings? gaskets, bolts, seals etc.:))
-
Check the swingarm pivot very carefully, its expensive but most of the time is more worn than the bushes
-
Good point Brian I re grease mine every 1000 miles
Mick
-
Same here except on all occasions I mess around do it wether it needs it or not
Cheers
