The base plate or transducer, depending on model, should be mounted onto a rigid surface.
See Figure 1 for bolt hole pattern. Place the bolt assembly just completed into the shroud and
then onto the transducer or base plate. The last step is to apply the steel washer onto the bolt
before applying the nut.
IMPORTANT - Grease the threads and fit the nut.
- Ensure that the threads are kept clean and lubricated.
The joint is now ready for use. Eventually the bolt and nut threads will wear and will need to be
replaced. IR recommends replacing worn joints with the appropriate bolt kit that matches your
joint kit model: JKS30-BKIT, JKS150-BKIT, JKS300-BKIT or JKS1000-BKIT.
