I very rarely change a drive chain and when I have I'f normally had access to power points to remove the chain. This time I don't so I'm looking for alternatives.

Has anybody ever hacksawed or used bolt croppers on an old chain? Which is best, any other suggestions?

Thanks for any help.

Without power tools I have managed to split one using a file, a chisel and a large lump hammer. Although a battery angle driver would have been much easier.

Bolt croppers snip drive chain very easily. You might need to adjust the jaws to "close", that's all. No fuss, no mess.

Thanks for the help, much appreciated.

I'm now having another issue which I'll put in here regarding fork guide bush. What are people DIY ways of installing these? The bush needs to be compressed and pressed down simultaneously to fit.

Thanks for any help.

Bit of plastic waste pipe with a similar ID to the fork OD and a mallet.

Thought that was going to be the suggestion, which is what I've done before. However my current forks are 46mm stanchion diameter. So finding a 46ID and a 50-ish OD is proving tricky.

Sir could perhaps find a shortish length of 50mm and expand it by resting a hot piece of bar or tube along the inside. I assume someone sells a boring old tool to do the job though.

In fairness, yes, just buy the fucking tool. having done so, I wish I had bought a seal driver years ago. You can get adjustable ones that are pretty much universal.

Next on the list is a blind bearing puller.

Blind bearing pullers are fairly cheap now for hobby-grade ones. I think my set was under £50, and has been worthwhile.

Fitting bushes, I use plastic plumbing waste pipe. If it's too small to fit over the fork, I just cut it lengthways and open it up so I get a snug fit over the fork and coverage of most of the bush.

Bushes shouldn't need that much force to drive in. Make sure the fork leg where the bush sits is clean - a quick clean-up with a finishing pad or very fine emery paper to remove any corrosion, varnish or crap. Also good to run a pick or very small screwdriver around the bottom of the seat where a bit of crap tends to accumulate.
