Anyone know the belt numbers that go on this dozer? I have the old ac part numbers but they aren't any good....it has the 344 Buda engine, any help would be great.

| IIRC you need to put a "7" in front of the old Allis number these days |

| What are the numbers you have? Someone might have them crossed in their notes if they know what your numbers are. |

| Also, if you have the old numbers, post em in a want ad in the classifieds section of the forum here. A few folks on here have NOS parts, and may have the belts you need. Darrel |

If you have the Buda HD344 as opposed to the Allis Chalmers HD344 aka Allis Chalmers 6000 motor the belt size is no longer produced. That is what I found when my HD6G needed belts. The Buda motor has the horizontal injectors and you have to remove the crank driven hydraulic pump to change the belts. Good luck |

For the Buda 516 in an AC Forty Five grader (which I think is the same engine front end) ours uses C 60 for the fan and C53 for the pump - that with an alternator fitted though. |
