I looked into replacing my worn bearings and found either plastic or rolled bronze available
now due to keeping prices down these are made down to a price (nothing wrong with that makes them affordable)
But if you want the best machined phospher bronze and hardened silver steel pins are the way to go
Now nobody makes these as far as I know so I made a set up (if people are interested I'll post how to but it's involved)

Although a lot of you might lack some of the tools here but the basic idea is the same as fitting any set of bearings so I thought you might find it useful and some of you might have an relative or mate who can do the machining for you

Old bearings you can see why they need replacing

Jason again

making things is your hobby right?

but post the insructions. very hot bearings!

First strip all the bearings down so you're left with just the bare frames like so (oops forgot to take pic of the spring braket stripped)

You got it jump-up

Jason · « **Reply #6 on:** July 18, 2007, 08:58:56 PM »

Next you have to ream the holes to make them round ( they are punched at the factory and sometimes come out oval also the new bearings are slightly bigger ) and then debur

The top bracket has a blue plastic spacer that only goes between the bearings now to improve this I made an ally full width one to keep the frames apart (so no flex under stress)

Jason · « **Reply #8 on:** July 18, 2007, 09:02:08 PM »

The spring bracket has the plastic roller and as the new shafts and bearings are larger this needs to be machined

Now the bearings need to be stuck in I use an anerobic retainer (it will stop them rotaton and wearing the frames )

The under foot one is easiestjust press the bearings in and slide the new hardened tubes in ( I used grease with Molybdenum Disulphide it makes bearings last ages (like a teflon coating))

thats amazing wish i could make my own stuff for when i wear stuff out instead ill just be paying money for new stuff
your really good at it...

Jason · « **Reply #12 on:** July 18, 2007, 09:06:10 PM »

Spring bracket same but put the plastic roller between the frames first

Jason · « **Reply #13 on:** July 18, 2007, 09:07:24 PM »

Thanks Dave I enjoy doing it

Jason · « **Reply #14 on:** July 18, 2007, 09:08:04 PM »

Top bracket needs the ally spacer in first but otherwise the same again

x_Rave_Dave_x · « **Reply #15 on:** July 18, 2007, 09:08:16 PM »

looks like a great hobby keep up the good work

Jason · « **Reply #16 on:** July 18, 2007, 09:09:25 PM »

Finally reassemble all the bolts using grease between the bearings and inner washers

Jason · « **Reply #17 on:** July 18, 2007, 09:11:09 PM »

The finished item infront of the first of my homemade crash mats (notice the foam for the rest)

Jason · « **Reply #18 on:** July 18, 2007, 09:12:23 PM »

I know this project is beyond anyone that does'nt have a lathe and the rest of the tooling but I hope it is of interest to a few and if anyone does decide to have a go I'll do some mesurements and drawings for them to make the bearings

The best bit is with only 2 thousanths of an inch clearence on the bearings I now get absolutely no wobble at all

Thanks for the space Naz ( know I use a lot

)

Thanks for another great tutorial Jason

I think I need to make a new section titled Jason's Mods

Much appreciated

Hey slow down Naz my heads big enough (according to the wife)

But praise is always gratefully accepted

Nice work Jason, your ingenious mods amaze me!

Jason · « **Reply #22 on:** July 19, 2007, 10:22:53 PM »

Thanks Sprog by the time I get to Capital Bocking we will see if this one is a success or not

it seems to be good so far
