Dunham Bush scew

[RANGER1]

Currently working on a Dunham Bush 255/105 ( Frick old type ) .

Are there many around these days still running in USA etc .

Pain in the neck to o/haul due to main bearings requiring line boring .

Hi Ranger1

I work on several old Frick and FES packages that use Dunham Bush screws. You are right, they are a pain to overhaul.
