- Backhoe Loader:
- 446D (S/N: DBL1-UP)
Some 446D Backhoe Loaders may experience misalignment of the alternator pulley. The alternator pulley is offset from the crankshaft pulley in most cases. Check the alignment of the alternator pulley and the crankshaft pulley. If necessary, install a 8T-4121 Hard Washer behind the alternator pulley. After installation of a 8T-4121 Hard Washer, ensure proper belt tension.
