Good stuff, when you put motor back on see if you can slightly angle the key. It will straighten up when slid over.
Theres many variations of same machine, yours looks like a short bed with elevation handle and locks on left.
Check the caps first a new motor will be costly compared to a new machine.
ie elevation transfer box for mine was £244 excluding the motor, whole new machine was £930. Its where these Chinese machines sting you, same with others. Motor for RF25 was £256 any years ago (12) new machine £800.
