Hello from Merseyside

Just thought I would join up as some one was telling me all about this site.

I am a keen engineer currently building a custom motor bike with my son for a school project.

Currently looking to buy or build a hydraulic press as we need one to remove the swinging arm pin

Hello Dave.

Is it a BSA C15 that you and your son are building? You mentioned it in another post. Have you any photos of progress?

I bought myself a new 20 ton hydraulic press a couple of years ago, it cost around £300. It makes otherwise impossible tasks a doddle, although I haven't needed to use it on my two BSA motorcycles yet.

Hi Dave, I have a 12 tonne hydraulic which was advertised on a well know auction site as a shop press - I got it for £100 as that is US terminology. Think before you use it as it is easy to do a lot of damage.

I made up a frame from 3 x 3 box section, welded together to make a portal frame, and used a 6 ton hydraulic jack as the power source. It was used to change a lot of Ford Cortina half shaft bearings.

Just be sure that the parts that you are pressing will not fly out sideways, if anything slips! And that you are exerting pressure on the parts that you should, otherwise you may well break something.

Making dollies to press bearings in or out is just simple turning, and makes life so much easier than "bodging"

Welcome to the forum, Dave.

You couldn't make do with something made a bit like a bush extractor?

hi dave so you have found the joys of bsa c15/b40 swinging arm pins and bushes, the pin wears on the ends ,so you have to push the worn bit all through the main frame , not to bad if you have the bike apart , as a kid (a long time ago) in my dads motorcycle shop i can remember him laying the bike on its side with wood blocks underneath and using a big old hilti drill with a home made adaptor to punch out the pin , lots of noise but the pin came out , and new bushes /pin and shim were fitted and the bike ready for its mot inside an hour , in fact i inherited all of his old special tools and used the adaptor last year to replace a set on a triumph cub which use the same system , if you have not done one before the only problem if you do not have the long factory reamer is keeping both bushes in line , i now use an adjustable reamer with a 8mm internal thread in the end and made various mandrels to screw in to line up when reaming bushes , just remembered the bantam range used the same set up . cheers will

Sorry for the late reply.

Yes its a C15, we bough a complete bike and a scrap frame, the scrap frame will be made in to a Bobber and the bits swapped over, then we can easily convert it back to a classic bike once the projects over as we didn't want to spoil a classic but its all we could find for our budget..

No worth while pics yet

Just finishing the Frame jig to hold it still whilst we cut it and re weld it.

I need the press for removing the rear swinging arm and a few other jobs we do at home, I keep saying I will make my own but still haven't.

Looking for a few C15 bits

Fork leg bit that holds the oil seal.

A rear mudguard any condition as it will be cut up.

A stand alone head light and stand alone speedo

Something interesting to make a rear light from

So have a root in your shed.
