Among my spoils from the auction the other day was a job lot of miscellaneous pullers. The main item I wanted was worth the bid price, but there were some oddities which have got me stumped.
Strangest is this lot, made by OTC:-
All I can think of is that the rod can be slipped through one of the discs, which will then hold if it's pulled square against something such as the back of a bearing, as in
Maybe there's some vital part missing?
I suspect the other bits in the tray aren't directly relevant.
The rods have part numbers such as HC-690-E (or C or D)
The discs are HC 690-A1 (or B1, C1 etc)
Googling OTC hc-690 hasn't found me anything useful.
Next is presumably a special, I thought at first it might be for extracting bearings while the shaft is in place but the removable jaws are only 2-piece so couldn't be slipped through an outer race from the front. The jaws are about 100mm bore. It looks to be part factory made, part shop made, and to have had quite a lot of use.
Any bright ideas? Thanks Tim
