    Default Hercus Gear Rack ??

    More treasures from my dad's garage. Can someone tell me what these are and if they would be of use/value to anyone?

    There were 12 in a box stamped (maybe by dad) HERCUS 48F6P

    Hello John,

    Hercus made a number of stock racks. In the copy I have of their 1979 Transmission Equipment catalogue, they list a 48F6R (not P) rack. It was 48 1/4" long, 2" wide and 1 1/2" high. It had 92 teeth with a pressure angle of 20 degrees and was made from mild steel. They weren't specific about the grade of steel but the pinions they produced to suit the racks were made from 1045. Your racks may have been specially made or simply cut from longer lengths to suit some now unknown application.

    Bob.

    Thanks Bob.

    I will probably put them up as freebies in market place in case someone can use them.

    On closer inspection I believe it is 48F6R.
    Thanks. They are in market place now.
