- Set of tube keys. Inch sizes for American and metric engines for European or Japanese engines. You don't need to spend a fortune on a game because you're not going to use it every day. However, do not buy waste because you can use them to work on other equipment. A 3/8 inch ratchet is fine, or a smaller size of 1/4 inch for use in confined spaces.
- The combined Keys, open at one end and the ring at the other end, are also useful. These can be used for situations in which a nut needs to be undone, but the threaded section of the screw extends too far beyond the nut to fit into a socket. The keys are also known as spanners in the UK. It is not necessary that the sockets or keys are greater than 3/4 of inch AF (in the planes) or 19 mm of size.

Before dismantling
Before you begin to dismantle everything, take some high resolution photos with a digital camera if there is any chance that you forget to forget how to reassemble the pieces.
In addition, if you need to remove many washers, bushings, springs and nuts on an axle or bolt, you can thread them into a piece of cable to track the reassembly sequence.
