Usage:
NOTE: This Program can be administered either before or after failure. In either case the decision whether to apply the Program is made by the dealer. When reporting the repair, use "PS40204" as the Part number and "7755" as the Group Number. If administered before failure, use "56" as the Warranty Claim Description Code and use "T" as the SIMS Description Code. If administered after failure, use "96" as the Warranty Claim Description Code and use "Z" as the SIMS Description Code.
NOTE: Some of the Affected Product fall into more than one group. Do all applicable portions of this Service Letter at the same time.
Termination Date
May 31, 2002Problem
The welds for the rear and/or front frames need to be inspected on certain CB-334D and CB-335D Compactors. Due to inconsistent welding procedures the welds may be cracked. If cracks are present they will be visible in the center of the weld(s). If cracks exist they must be ground out and rewelded. Affected Product Note:

- (1-Rework Procedure)
Rework Procedure
This rework will involve 100% inspection of both front and rear frames where applicable.
Inspection involves:
1. Remove platform.
2. Remove water tank.
3. Inspect rear frame welds (see attached photos)
4. Inspect front frame welds. REPAIRS Front Frame

Front Frame
1. If crack is near fuel tank, remove engine and fuel tank.
2. Repair as per the repair procedure steps that follow.
Rear Frame
1. Repair as per the repair procedure steps that follow.
Repair Procedure
The areas to be repaired (shown in the following figures) and the surrounding area must be at a minimum temperature of 16 degrees C (600F) before and during all cutting, carbon arc gouging, and welding. Grind or arc out the portions of the weld that are cracked. The crack may be longer than visible; be sure that the cracked weld is removed entirely before rewelding. The Shielded Metal Arc Welding (SMAW) process shall be used with E7018 (ANSI/AWS A5.5) welding electrode. Weld size required is 6mm.
These are low hydrogen electrodes and must be stored in an electrode oven at 121 0 C (250 0 F) when not in use. If the electrodes get damp, scrap or recondition them to manufacturer's specifications. The following chart relates to the electrode diameter and approximate current settings for welding:
Use the direct current electrode positive (DC reverse polarity) setting and remove the slag after every pass. The weld pass size shall not exceed two times the electrode diameter.
As an alternative process the Flux Core Arc Welding (FCAW) process may be used with E71T-1 (ANSI/AWS A5.20) welding electrode and the manufacturers specified shielding gas(es).
Welding parameters will vary due to weld position and manufacturer of the welding electrode. Use the direct current electrode positive (DC reverse polarity) setting and remove the slag after every pass. The weld pass size shall not exceed 8mm (0.31") fillet volume.
