I have the original book from Trojan but I can't cross reference the book numbers to find the 3 belts for the blower, alternator and compressor. If anyone knows them that'd be awesome.
Just for kicks can you post the part numbers you have? A lot of times companies use OEM part numbers but add a couple digits to confuse you! As you are referencing "blower belts" I'm making the leap to assume this has a Deutz F6L913 6 cylinder engine? If not that model what does it have? Are there any numbers on the old belts? What about pulling them off an take them to say a NAPA dealer?
