I recently took off the chain and gear assembly on the side of my acto light 14 1947. The problem is now after reassembly the chain keeps coming off when I engage the clutch. Upon inspection there appears to be quite a lot of play in the drive cog (the one between the other two) and it twists.
can someone please help? I don't think I lost any bit when reassembling. Does anyone have a diagram or can advise how this can be tightened up as apart from the split pin head on the end there is no way to tighten up this part of the assembly.
