Service Bulletin Toolkits

West Coast Industries provides several tooling kits for overhaul and repair work. These include the CrackArrestor for enchanced stop drilling, CWORK-2B which includes both capital and expendable CR tooling for existing fastener sizes between ⁵/₃₂ - ³/₈", and the CWORK-1 and the CWORK-3 kits containing CB tooling to coldwork holes ranging from ³/₁₆¹³/₃₂" and ⁵/₈ - 1" respectively.

We supply custom commercial Service Bulletin Kits to the world's airlines for specific rework applications. These contain both capital and expendable tooling, or the customer may rent the needed capital tooling. Complete on-site training is recommended to insure your personnel are completely certified in coldwork procedures. Custom configurations can be designed for most any rework application.

CrackArrestor Tooling Kit

Stop drilling has long been used as an interim repair procedure. Most stop drills are not successful because the leading tip of the crack is missed. The CrackArrestor system significantly enhances the stop drill process by cold expanding the stop drilled hole. Coldworking the stop drilled hole greatly enhances the chances that the very tip of the crack becomes protected in the zone of compressive residual stress induced around the stop drilled hole. As a result, the interim repair becomes more successful. Field and government tests have shown significant life improvement factors compared to stop drilling alone.

CrackArrestor kits contain all tooling needed to stop drill ³/₁₆", ¹/₄", and ¹⁷/₆₄" oversize holes, and include a small hand puller unit, along with extension nosecaps for each size. The full kit contents are listed on the facing page.

Overhaul and Repair Kits

Overhaul and repair facilities have special fatigue enhancement needs. WCI tooling kits meet these needs by providing all the equipment (capital and expendable) needed to coldwork 100 existing fasterners of any one size. The tooling is based upon West Coast Industries Process Specification, PS-9201. The CrackArrestor, stop drill enhancement kit, is included with the CWORK-1 and CWORK-2B.

All tooling is contained in a mobile, four drawer cabinet on casters

Additional tooling sets may be placed in cabinet

One day of on-site, or in plant training is provided with the purchase of each tool kit (excluding airfare)

Tooling is specifically optimized for rework applications

Nominal hole size and oversize tooling is provided

Each hole size tooling set is contained within an individual high-impact plastic toolcase

CWORK-1/CWORK-2B include the 1700-OA offset adapter and extension nosecaps for restricted access problems

The 1700-20 puller gun and WCI-20 power unit are standard with the CWORK-1/CWORK-2B kits, while the 1800-30 is included in the CWORK-3 kit

Additional tooling may be ordered at the same time at a substantial discount

Dimensions 43½"H x 28½"W x 28½"D
