I have a B7001 SN 20612 that requires a front diff assembly. I have parts manuals for the the B7100. My question is I have two manuals one for old (B7100 SN <20024) and new (B7100 SN >20025). Does any one know if mine would be an old or new style as the diff case part numbers are slightly different.

also refers to old sn <60163 and new sn >60164?

Welcome to the forum,

Are you sure you have a B7001? Many people see the serial number and it says B7001-xxxxxx
yet it really is an early model B7100

Does it have 4 bolt front rims? If it does it will be the "old style" ........... now the real difference will be the tires on the front..... a true B7001 has these tires:


No code has to be inserted here.

where as the B7100 has these:


No code has to be inserted here.


the internal gearing is different too!!! SO some parts do not interchange inside - most parts will work on the outside however.

Take a couple of pictures - one of the dash panel too!

based on ALL that great info ........... no doubt ...you do have a B7001!

Finding your parts may be harder yet to find unfortunately.
