Heavy-Duty Pulley Blocks

[Ulma Doctor]

be sure to lube the SS pin with MoS4 grease or other extreme pressure grease of your choosing , to prevent galling of the stainless

I'm worried the stainless will be up to the task. If it is, certainly the zerk and grease before you load it up with tonnage.
I would have done a 4140, or 4130.. ss is generally soft, and your metal is sought of soft, so 2 softs... gall...
grease please...

Yes, thanks.

I could also see (if there's any problems in the future)
i) replacing the stainless pin with something else, or
ii) boring out the pulley centres for a roller bearing.
