Tools and working facilities The first priority when undertaking maintenance or repair work of any sort on a motorcycle is to have a clean dry well lit working area Work carried out in peace and quiet in the well ordered atmosphere of a good workshop will give more satisfaction and much better results than can usually be achieved in poor working conditions A good workshop must have a clean flat workbench or a solidly constructed table of convenient working height The workbench or table should be equipped with a vice which has a jaw opening of at least 4 in 100 mm A set of jaw covers should be made from soft metal such as aluminium alloy or copper or from wood These covers will minimise the marking or damaging of soft or delicate components which may be clamped in the vice Some clean dry storage space will be required for tools lubricants and dismantled components It will be necessary during a major overhaul to lay out engine gearbox components for examination and to keep them where they will remain undisturbed for as long as is necessary To this end it is recommended that a supply of metal or plastic containers of suitable size is collected A supply of clean lint free rags for cleaning purposes and some newspapers other rags or paper towels for mopping up spillages should also be kept If working on a hard concrete floor note that both the floor and one s knees can be protected from oil spillages and wear by cutting open a large cardboard box and spreading it flat on the floor under the machine or workbench This also helps to provide some warmth in winter and to prevent the loss of nuts washers and other tiny components which have a tendency to disappear when dropped on anything other than a perfectly clean flat surface Unfortunately such working conditions are not always available to the home mechanic When working in poor conditions it is essential to take extra time and care to ensure that the components being worked on are kept scrupulously clean and to ensure that no components or tools are lost or damaged A selection of good tools is a fundamental requirement for anyone contemplating the maintenance and repair of a motor vehicle For the owner who does not possess any their purchase will prove a considerable expense offsetting some of the savings made by doing it yourself However provided that the tools purchased are of good quality they will last for many years and prove an extremely worthwhile investment To help the average owner to decide which tools are needed to carry out the various tasks detailed in this manual we have compiled three lists of tools under the following headings Maintenance and minor repair Repair and overhaul and Specialized The newcomer to practical mechanics should start off with the simpler jobs around the vehicle using the BMW tool kit which is sufficient for all normal maintenance tasks Then as his confidence and experience grow he can undertake more difficult tasks buying extra tools as and when they are needed In this way a Maintenance and minor repair tool kit can be built up into a Repair and overhaul tool kit over a considerable period of time without any major cash outlays The experienced home mechanic will have a tool kit good enough for most repair and overhaul procedures and will add tools from the specialized category when he feels the expense is justified by the amount of use these tools will be put to It is obviously not possible to cover the subject of tools fully here For those who wish to learn more about tools and their use there is a book entitled How to Choose and Use Car Tools available from the publishers of this manual Although as its title implies this publication is directed at car owners the information given is equally applicable to motorcycle owners It also provides an introduction to basic workshop practice which will be of interest to a home mechanic working on any type of motor vehicle As a general rule it is better to buy the more expensive good quality tools Given reasonable use such tools will last for a very long time whereas the cheaper poor quality item will wear out faster and need to be renewed more often thus nullifying the original saving There is also the risk of a poor quality tool breaking while in use causing personal injury or expensive damage to the component being worked on It should be noted however that many car accessory shops and the large department stores sell tools of reasonable quality at competitive prices The best example of this is found with socket sets where a medium priced socket set will be quite adequate for the home owner and yet prove less expensive than a selection of individual sockets and accessories This is because individual pieces are usually only available from expensive top quality ranges and whilst they are undeniably good it should be remembered that they are intended for professional use The basis of any toolkit is a set of spanners While open ended spanners with their slim jaws are useful for working on awkwardlypositioned nuts ring spanners have advantages in that they grip the nut far more positively There is less risk of the spanner slipping off the nut and damaging it for this reason alone ring spanners are to be preferred Ideally the home mechanic should acquire a set of each but
