Steering Assembly
One of the most important factors in the installation of the steering assembly is the kength of the steering lines. Too loose and someone will trip over them. Too tight and either they won't have enough play to work properly or they might not reach the engine. Proper measurement will ensure that the correct length of cable or hose is bought for your system. Refer to measuremewnts A, B, and C in the diagram below:
