GENERAL INFORMATION: Solar’s Customer Services business is under constant pressure to reduce costs and lead times due to increasing competitive elements. We want to be the supplier of choice for all facets of our business, focusing on the customer’s needs and wants. The remanufacture of package components is an important facet of our business and is desired by customers. To improve the support of the reman business, Solar has dedicated package component remanufacturing facilities worldwide to provide superior quality, product reliability, and quick turnaround times for repair and for exchange options for the customer. By providing this service, our goal is to increase our value to our customers as a resource you can rely on. SERVICE BULLETIN NUMBER: 1.0/115C Caterpillar: Confidential Green Page 1 of 4 Solar’s remanufacturing facilities specialize in component repair, calibration, and testing to ensure a quality product for the full range of package components for Solar’s equipment. The following are just a few of the parts we provide this service for: Fuel Control Valves (both gas and liquid fuel) Engine Control Monitors Electro Hydraulic Actuators Package Pumps, Valves, Actuators etc. Engine Fuel Injectors Start System Components. In addition to the internally serviced parts, such as those mentioned above, we also continue to team with our external suppliers to improve servicing of certain parts which we must send out for repair. To ensure we can facilitate this process and serve you better, it is vital that the reman facility you work with receives the appropriate information and documentation when you are returning a part. When a part is received without any documentation, we have no direction as to how to process it, what order number it relates to, and it can be easily lost. Please help us to avoid this situation as we continue to strive to improve our service to you. ACTION REQUIRED: First, acquire an order number: Please obtain a Return Material Authorization (RMA) or Sales Order number prior to return of any goods. This can be quickly obtained by contacting your local Solar Service Parts Sales Office and supplying basic information about the return. In doing so, an electronic record will be created by which your return will be tracked and processed, and a form (acknowledgment) containing this information generated which you should include with your shipment for positive tracking. To initiate a repair or exchange, please contact Solar’s Service Parts Office with the following information: • Part Number and Quantity of the item being repaired or exchanged. • Correct Ship-to and Bill-to address • Does this qualify as a warranty claim per Service Bulletin 19.1/100B? – If not, a purchase order is required to cover the repair and freight charges. – If this is a warranty claim: o Explanation is required as to why the goods are under warranty, i.e. the unit is still under year warranty or the warranty request is to replace an item that has just failed and is less than 12 months old. o A purchase order is still required for the freight charges only.

The RMA will include any initial pricing for the required rework. Please help us improve our service to you by assuring that any staff involved in returning goods follows the instructions below: Second, mark your shipment with the order number: Please mark the parcel, crate, container, etc. containing the goods for return clearly with the RMA or sales order number.
