set screw. Heat hub to 275ºF (135ºC) using an
oven, torch, induction heater or an oil bath.
To prevent damage DO NOT heat hubs beyond a
maximum temperature of 400ºF (205ºC).

an excess acetylene mixture. Mark hubs near the
center of their length in several places on hub body
with a temperature sensitive crayon, 275ºF (135ºC)
melt temperature. Direct flame towards hub bore
using constant motion to avoid overheating an area.
If an oil bath is used, the oil must have a flash
point of 350ºF (177ºC) or higher. Do not rest hubs
on the bottom of the container. Do not use an open
flame in a combustible atmosphere or near com-

Heat hubs as instructed above. Mount hubs as
quickly as possible with hub flange face flush with
shaft end. Allow hubs to cool before proceeding.
