Just a follow-up to my anemometer repair...
A few months back my wind direction vane became stuck. Unlike the anemometer, which just had a 'sticky' spot, but would still turn in a moderate wind, the direction vane was stuck fast – couldn't even move it by hand! It was rusted solid (remember I live right on the ocean!).
Getting it apart is the same process as for the anemometer, and its construction is identical for the top half. I prised the bearing up off the post, and found no numbers on it (it's pretty small - where would they fit a number?
), so I measured it with vernier calipers.
I found a stainless steel sealed bearing with the same dimensions, bought online and fitted it, and now everything's working well again. The supplier listed below is in Australia, so postage would probably kill this source for those of you overseas, but it may be of use to other Australians experiencing this problem, and others might find the same part number overseas somewhere. I'm assuming (but haven't measured) that the anemometer bearing would be identical.
Supplier:
http://www.smallparts.com.au (
sales@bearingshop.com.au)
Bearing part number: SMR105A-ZZMC3
ID: 5.000 mm
OD: 10.000 mm
Width: 4.000 mm
They were $5.36 each incl. GST (I bought 4), with $9.35 total postage (within Australia), though the current price seems to have risen slightly since then.
I'm glad others have found my article useful, and hope this additional info is also of use to somebody.
