    Seized Chain Adjuster

    Doing some pre winter maintenance it appears that the chain adjustment plate on the left said is seized in the swing arm.  No doubt due to lack of maintenance.

    Any ideas how to free it up before I resort to a hammer?

    Thanks

    That's virtually impossible with the amount of play there is between the adjuster the adjuster and swinging arm, have you slackened off the axle nut?

    Is there any horizontal movement in the axle?

    That's Art.

    No axle is seized too probably around left swing arm area.  I put some penetrating fluid on last night but aren't that confident of getting the axle moving.  Hopefully wonders do happen.

    Maybe a job for local shop. I'll have another go tonight.

    Remove the axle nut, support the weight of the wheel on a piece of plywood and wooden chock or similar (photograph to follow as I'm taking my rear wheel off for a new rear tyre later today) and tap the axle with a soft polyurethane or rubber mallet to free it. To completely remove the axle you will need to rotate it (lefty loosey) as you pull it out by hand.  If you don't have a soft mallet eBay, Amazon or your preferred tool supplier should get you sorted for around 5, no need for the home mechanic to buy anything reassuringly expensive here. Attack it with a hammer monkey boy style at your own risk of damaging the threads, when re-assembling the adjusters and axle a goodly coating of a general purpose lithium grease, torque to 98 Nm (72 lbf-ft) no more no less, noting the axle nut is a re-usable U- nut with a friction clamp cut into the top threads.

    Never got around to that rear tyre but here's my rear wheel tool kit. Note the piece of ply and wooden chock supporting the weight of the rear wheel and the No3 cross point screwdriver to line up the rear wheel, axle and swinging arm when re-assembling.

    Don't forget to coat the adjusters and axle with a general purpose lithium grease.

    Thanks Art.

    I will have a go in a few days to free the axle and adjuster.
