Bob is correct and it is not complicated to do, if you can note the order of parts.
One only needs to remove the scew coaxial with the forks of the take up spool and withdraw this screw, washer, fork etc.
The gear wheel driving the forks is held in place (sort off) and should not dissappear into camera.
The clutch action is friction and is driven (controlled) by the spring and washers which drops out with the forks, altering the spring length is diffiuclt without a vice and removing a washer is easier (and reversible). Note the sequence of each part on a notebook with pencil, text and drawing, in addition to dig photo if you can.
But unless you have damaged sprocket holes I'd ignore, if the spacing upsets the automated processing it is a more difficult decision, buying another Kiev may be easier.

If you have a later camera you will have to remove the three screws to drop the fixed take up spool first, stick the screws to pressure sensitive tape attached to camera, and work over a deep tray.
