PREPARATIONS: RESEARCH & TOOLS
As engines have become more sophisticated, the importance of not disturbing manufacturer-set timing has become even more critical. Keith Anderson, technical writer at Laser Tools, notes that timing belt changing tools evolve all the time. You can check which tools are applicable for your car by looking up the make and model at www.lasertools.co.uk/ products/ Engine-timing-tools
It is worth noting that some motor factors operate tool hire schemes. Keith says also that obtaining the correct tools is the easy part, but obtaining specific manufacturer data can be more difficult and that Diyers should factor in the extra potential expense of sourcing data along with parts and tool costs. More modern engines will require more advanced locking tools. It’s worth investing in the correct equipment, rather than risk the cam and crankshafts moving when the timing belt has been removed.
For some basic engines, you may be able to use a long bolt of the correct diameter to lock the cam and/or crankshaft, instead of a dedicated locking pin. Be wary that a drillbit could fall into the crankcase.
