Chassis bush removal

[Warb]

I just found this video on YouTube. There is a video response that shows how the tool was "made" - it's just the thread from a scissor jack. Hope it helps somebody! If I can find an old scissor jack around the farm I might try it to fit the new bushes in the chassis I've just painted.

Hi Andrew, that's fine if the bush is capable of being pulled through, but more than likely it's rusted in solid.

A puller like the one in the movie will more likely damage the chassis that it's pulling against.

I'm more of the view that you get it out by burning out the rubber with an oxy or propane torch, then cut through the outer bush with a reciprocating saw.

It works for me anyway :)

As for pushingthe bush in - use poly bushes, and you don't have any problems getting them in or out.

why are polybushes easier to remove install?

...As for pushingthe bush in - use poly bushes, and you don't have any problems getting them in or out.
...The problem with poly-bushes is that they trap dirt and water turning it into a grinding paste and wearing away your chassis, ovaling and oversizing the hole for the bush. next time you want to fit new bushes original or poly they are loose in the chassis.

I did it once and only use the original style now.

I removed the SII bushes a few weeks ago. I drilled through the rubber (long 1/8" drill) in various places and then pushed out the middle section and rubber. Then, as you said, I sawed through the outer section and drove it out. However, whilst I was very careful not to damage the tube through the chassis, there are three saw cuts in it from previous peoples attempts!

The trick to using a puller (or pusher) is to make sure you're pushing the right item. The guy in the video uses a selection of sockets, but for tractors we turn down a piece that is exactly the right size, and use an air-over-hydraulic bush pusher that was made by a friend especially for the job. Sadly I forgot to bring it home when I did mine (it's also rather large for mere Land Rover bushes!) so I cut them out, but normally we make sure we're pushing the outer rim of the bush and the in this case the chassis tube rather than the flats of the chassis rails.

Earlier this evening I fitted one new bush because I had a couple of minutes to spare. Standard steel/rubber bush, took two minutes:

1/ drum sander to clean rust, paint etc. from tube through chassis
2/ anti-seize on bush and inside tube
3/ bush pushed through using threaded rod, similar to video, with large washers to ensure pressure went on chassis tube and outer rim of bush (not stressing the rubber)

Poly bushes have advantages. I used to use them all the time to remove movement from suspension in performance situations, but those situations were clean and regularly stripped and inspected. For this LR I decided to use steel/rubber, not least because it's having Rocky Mountain parabolics and they suggest using steel/rubber and not poly.
