I didn't know Lovejoy's were a sintered metal! As Gordy mentioned they are a metal that is made by pressing together metal particles at a high heat lower than the melting temp. They are difficult to machine and usually have a rough surface look to them. I thought that Lovejoy's were machined then hardened by heat treating. The ones I've seen on the Case tractors are aluminum. Back to the sintered metal being weldable? I would say the success would be poor.DavidBarkey wrote: ↑Mon Feb 14, 2022 8:29 amThis lovejoy is 1" bore . I have no shortage of pulleys salvaged in stock. My first thought is to back cut a the lovejoy L-099 with a centering collar , drill and tap for 3 x 1/4" bolts . Take a pulley that will fit nicely in the bracket and machine corresponding bore and drill 3 mounting bolt holes to match .Gordy wrote: ↑Mon Feb 14, 2022 1:20 am Dave,
I have not had to mess with the lovejoys, but I understand the crankshaft is only 1" or 1.125" long and the lovejoy must take up most of that. So the question is how do you intend on mounting a pulley in there? My first thought is to find or make a hubless pulley and weld it to the lovejoy, like the sprockets at Tractor Supply, pick the sprocket you need then pick the hub you need and weld the 2 together. Or find a pulley with a large enough bore to fit the outside of the lovejoy, then cut a keyway on the outside of the lovejoy.

I am not sure how the lovejoy would take weld as they are cintered metal . Maybe Harry would know .
