This from a friend:
Now one for you to ponder: I'm after a couple of bearings for my Howard Dragon rotavator - the ones that support the tine shaft. One bearing is completely shot (as in it's in two separate pieces), the other is OK, but I work on the principal of doing this job (semi) properly. The only markings are: England PF 135 30. It's 30mm internal bore, 72mm external dia, inner race 30mm wide, outer race 19mm wide, triple rubber sealed. I think it is what is known as an Agricultural Bearing (due to the two different race widths). I've trawled countless websites to try and track them down - but no luck.
Can anyone help?
TIA
Richard
