Hi all.

Hoped to dust off my old 2011 Kona Fire Mountain and either restore the chain or get a new one. It was fine when I garaged it for storage but unfortunately now facing this issue, any help would be so appreciated.

 
I havent had too much time to look at the video properly, but the fact that your chain is completely orange (rust presumably), that won't help with the drive train running smoothly. And might explain why the derailleur is catching and being pulled.
 
what he said, start by oiling the chain, see how it is after.

It also looks possible that the rear mech or the hanger is bent.
 
I have found a chain for it in Halfords. It says below 'push pins' for easy fitting - does this mean I need a chain link tool still? Cheers

The SRAM PC-971 Bike Chain is compatible with 9 speed bikes and because of its PowerChain II technology and Powerlink Gold Chain Connectors it has super strength. For easy fitting and amazing durability this chain has chrome push pins. It's a quality, reliable chain to have on your bike.

SRAM PC-971 Bike Chain Extra Info
  • Compatible with 9 speed bikes
  • Push Pin Power: 200 kgf, Chrome Hardened Pins
  • Technology: PowerChain II & PowerLink Gold Connector
  • Weight: 298g/114 Links
  • Colour: Silver
 
The vast majority of chains will come with more links than you need, so even if they come with a QuickLink/MasterLink for easily joining the chain together (no tool required) you'll still need a chain tool to initially 'trim' the chain to the correct length.

The fact that chain doesn't mention QL/ML then you'll need a chain tool for fitting it too.

Don't forget to use the old chain as a guide as to how long to make the new chain.

The old chain is 3 links shorter than the new chain - so will take out 3 links.

Unfortunately I think this part is also bent which doesnt help, is it fixable - is this the "mount" or "is this the gear itself which needs replacing?

The top arrow fits into the little metal widget thingy but the plastic is snapped off (has been since I got it) but the bottom part is mishapen I think?

Can I bend it back (should I?) or will fitting a new one rectify the problem.

The frame's derailleur hanger needs to be straightened. Take it to a bike shop as they have the correct tool to do it properly.

The hanger looks quite a bit out of line and may need to be replaced.
 
DIY - would try taking the bend out of the derailleur hanger/drop out in a vice w/hardwood inserts, but may take a lot of force,
would probably put some (blow torch) heat at the bend prior to trying to flatten too.

It does not look replaceable ? (a side picture towards bike would clarify)
 
That is quite a bend to try and straighten.

It'll be hanger number 25 or 27, 25 on that Kona I think.

Alivio was 8 speed back then and counting the cogs I count 8 so really you want an 8 speed chain. Narrower 9 speed on the wider 8 speed teeth may cause problems.

I'd replace the mech too if it's never been right.
