Component Code(s): 6504-WTL, 6129, 6513, 6503, 7000SUBJECT: INTERFERENCE BETWEEN BUCKET LINKAGE AND QUICK COUPLER LIMITS BUCKET ROTATION FOR CERTAIN BACKHOE WORK TOOLS
PROBLEM:
Only partial rotation of the bucket can be achieved when the 169-5725 Quick Coupler is utilized with the backhoe work tools listed above. This is due to interference that exists between the 204-4079 Linkage and the quick coupler as the bucket is rotated. The 204-4079 Linkage is part of the 204?4078 Bucket Linkage Gp.
SOLUTION:
Investigation into the problem is underway. Until a solution can be effected, only use the quick coupler for attachments with the following backhoe work tools:
