I bought my Superstav EF2 (Bobcat B200) loader backhoe 2003 model with about 1400 hours on it in 2009. In 2010 the alternator failed. The stator was fine, diodes were good, brushes were good and ultimately we found that the field winding was open circuit. This is the winding that is on the rotor with which the current output of the alternator is regulated.
So I bought a replacement on Ebay (exact same Denso alternator) and today while moving dirt a little more than 150 hours after replacement, the battery lamp came on.....
The only thing I can say is that the alternator seems to get really hot. It has the radiator in front of it, no integral fan and the turbo is above and directly behind it. I don't know whether the heat from the turbo or radiator is the culprit, but a new alternator every 150-200 hours does not sound like a long term plan.
Anyone else have any issues with their alternator on the D1105 series engines ?
