  2. I saw that but the pulley is not (usually) a tight fit on the fan, there’s radial clearance that might now be filled with Por15. Is the balance weight still crimped in the pulley?

    Hope they are permanent markers. I’ve made that error before!

  4. Yes the balance weight is still there.

    I'm not sure what you mean by clearance. The star head bolts were done up pretty tight and the rear of the pulley was sitting directly on the fan. Small washers under the bolt heads, large flat-sided washers under the nuts.
  5. :D Yes, a Sharpie permanent marker

  7. Excellent read. Thanks. I'm glad my father-in-law has a lathe and I'll definitely get it on there to realign everything. So the clearance you mentioned was between the fan/pulley and the fan housing? I thought you meant between the pulley and the fan. If the paint is too thick I can always remove it from the rim
  8. I did mean between the pulley and the fan and the Samba link is showing how to centre the pulley on the fan using a dial indicator on the rim of the fan and the groove of the pulley. If you have POR15 where the two parts bolt together it should be removed so there is metal to metal contact.

  9. Fair enough. I can scrape it away from the mating surface. Thanks for the advice

  10. I don't know if the thickness of the paint would make that much difference given that a rubber belt will be running in the pulley. Scraped back with a razor blade anyway...

  11. The thickness of the paint is not the main problem. When these things are made the pulley is mounted on the fan and the assembly balanced; once you remove the fan it’s unlikely to go back in exactly the same position and the pulley should be centralised on the fan and the assembly rebalanced.
