Title: Bush extraction
Post by: Webby the Bear on 07 May 2015, 20:45:59
No Stmo, not what you're thinking  ::)

So, got an Astra in today, failed an MOT on rear axle bushes, so i was tasked with removing said bushes and replacing with poly powerflex thingys.

air hammer with big chisel. both sides out in 5 minutes!!!!!

so i trust this method will get any bush out in similarly easy fashion? any scenario that this wouldnt work?

ps, just to add bush removal being such a pain thats why ive never put polys before on my car, but if the air hammer method works this easy im more than happy to go for it  :y

.......

Just my opinion so I could be wrong.......

Air hammer chisel probably ok to use on fixed bushings where the fixing is rigid, rear axle for example, as it has something to kick against. Not so sure it would be any good for knocking out bushes such as steering arm etc as the arm has to be swung down, making it bounce rather than impact the part. Tube type bush removal tools are good for this as they pull against themselves on both extraction and insertion. You do need access from both sides with these though. The downside is that you need a set, as bush sizes vary from part to part.

Depends on condition ime

If they are so rusted and disintegrated as omega donuts often are, then anything akin to digging out with a stick will do. Any other technique is likely specific to the size and shape of the bush and how mush room is available.

There does come a point when the "avit" aporoach is all that's left :y

The rear rose bushes on a Vectra B are an absolute bastard to do without the extraction tool. You can't use an air hammer on them either, I tried with mine and the only way to remove them was with the correct tool...

As ChrisGixer says, they are the tube type of extractor thats needed on them. You can however make your own with suitably sized tubes/sockets and good quality studbolts and washers and good nuts...

I lost count how many 'proper' rose bush tools Iv stripped the threads of....

I ended up buying a very heavy duty, specially made custom tool off a lad on VVOC, I sold it when I scrapped the Vectra... wish I hadn't done now as theres been loads of people asking if they can borrow it LOL

Thanks for the input guys.

Did my first proper wheel bearing today (N/S/F on a Kia Rio)

Was properly good fun. And did it all myself very pleased.

I wonder if the press used for that would also be good for bush removal (i.e. get an old bearing that will sit nicely on the metal outer part of the bush and then press? I forgot to ask head. mech. any thoughts?

I keep old bearing races for just that purpose. Sockets also make handy presstools. Although you do have to be careful when pressing hardened material.
And if all else fails, custom tooling is easily made on the lathe or with the welder.
