So I decided to replace all my swingarm and linkage bearings so got all the parts and started to strip it all down. Got to the linkage to find all the needle bearings had disintergrated and were rusty. I managed to get the bushes out and have tried soaking and heating the bearing cases but the wont budge, and as i don't have a hydrualic press am stuck for how to get them out. Any ideas on were i could take it to get them pressed out??

find a socket that just fits in the hole put it upside down on a socket extension (so the square edge is facing down) then a good wack with a hammer on a hard surface always did the trick for me, but yea sometimes they can be a pain to get out. or sometimes i run a small weld around the inside of the bush to shrink it.

The cunning use of a 3 ton bottle jack.

this'll be funny to watch, he can't even give it a proper clean before the photos how do you think he's going to pay attention to the finer details of pressing them out without doing further damage!

Sometimes the only way is to collapse the bearing shell inwards by the use of a cold-chisel and hammer , just don't hit the alloy.

you're in auckland. i know for a fact there are at least two engineers in auckland.
go buy a box of beer, and get your mum to drive you 'round the engineering shops.

or, find someone awesome with a 4x4 ute and a bottle jack and use it against/between things that don't move, with the socket as suggested.

G Clamp might also work if you have one

Had this issue a few times before. I used a mixture of all thats been recommended above, G-Clamp to get a bearing moving, Chisel when getting anoyed and frustrated and the Socket works great if you can get one side out and other side is stuck. Best advice is to get someone with the correct tools and skills to do it, shouldnt cost much to get them out. Good luck.

a bench vice and the right sized socket also works well to take needle roller bearings in and out,

Yep plus 1, large G Clamp, vice, socket set and some WD40 will move most things.

Only one guy talkin sense here! Hammers chisels bugger me???

Bench vise, right sized socket easy as!

Just make sure you cover the serrated jaws on the vice or you will stuff the side opposite the socket.

you get this kinda stuff when u work on older bikes .......:bleh: some of the ones Ive seen there would be no way to get a socket on it ......

Ive machined a lump of steel , that work a treat even on brngs with no lip( sometimes)

Or a socket on one side, washers either end and the use the bolt/nut to pull the socket through.

It's effectively what the moion pro bearing pullers are, they are just more fancy.
