    Hello to all,

    As I have admitted on here several times previously, I am in no way mechanically minded. I did, however, heed the advice of more learned people on this forum and have purchased workshop manuals in a misguided attempt to educate myself on what goes on at the back of the bus. Returning from Sydney today, I threw a generator belt. No biggie, I had a spare and had changed them before..........but I couldn't. NRMA. The helpful chap pointed out that the pulley nut had loosened and, in his words, flogged the belt to death. Unfortunately, closer inspection revealed that the pulley had been damaged. Haynes describes this pulley, which is in two parts, as a rear half and front half. Muir defines it as a generator or fan belt pulley. I have looked on Bus Stop, Justkampers and Custom and Commercial with little luck. Could someone on here, please, define the common usage description of this part and where I may, actually, be able to find one one. 1972 Microbus.

    with thanks in advance,

    AJD

    Thanks Barry,

    Is that much the same as alternative facts and fake news?

    Barry, is there a difference in these parts for alternators and generators?

    Not sure what you mean

    The cheap ones wear out quickly
    The piece that "locks" onto the generator / alternator shaft can round out and cause things to wobble
    They spin at a very high rev and I have seen them shatter

    no - there is a difference between 6V and 12V

    What do you have ?

    Seeing as you have had problems make sure you get new
    pulley
    spacers
    wood-ruff key
    bolt

    Cheap quality results in trouble

    Thanks again Barry. Today I was able to go to Nymeyer Automotive at Belmont. Hendrick very generously, but somewhat reluctantly, agreed to sell me an original cast metal pulley. He said the quality of pulleys available for the last twenty years have been very poor. My mechanic up here will put it on tomorrow. Fingers crossed.
