David,
It's your call! But I had such a job getting the last one off that the bearing ended up in the scrap bin when there wasn't really anything wrong with it.
Be very, very, careful if you ever have to apply heat to a crankshaft / main bearing. SKF & Koyo (for example) recommend 125C as the max allowable temperature for their roller bearings (beyond which you risk distortions and metallurgical changes).
Are you sure it was Hoffmann's you spoke to? I thought they went out of business decades ago... I believe the name is currently owned by a group which sources / supplies old stocks of their bearings. I had one off them but (as was discussed on this forum) it arrived with (admittedly minor) corrosion etching on the races & I didn't buy another. I think the last new ones were made in about 1990? I'm sure somebody here knows.
Tony,
Do you know a source of SKF CRM 10?
I ran one in my Ulster rep for 30-odd years, though I'll have to dig it out to check whether it was an AU (?) or not.
