I am looking for a parts book for a allis chalmers tracker 8 snowblower, serial # 1467 manuf. # 1600262 . I have the op. Manual and I am looking to restore this snow blower I still use it ,but I would like to replace bearings ,belts and bushing, if I can find the part s to replace . That would be great if you could help me out with this. It seems I can't put allis chalmers in the manufacture spot so I put simplicity.
