Not a rare sight to see 20-30 year old MILNORS
The 420 rpm extract gave 75G’s …about the same as a whirlpool/kenmore belt drive
Milnor made a hard mount OPL machine on the same base that had 600 rpm that gave 158G’s
Yes, these were the 2 motor, 2 clutch, tied together by a jackshaft machines that had reversing contactors and time out relays that scared the shit out of a lot of people that were not familiar with them, but it worked. For more than 30 years, it worked and worked well.
I will ask anyone to find a machine that washed or washes as well, today…besides a Milnor.
I’ve posted this before, but it’s been some time…..
It’s easy when you look at it this way….
Motor 1 – wash motor
Motor 2 – extract motor
Clutch one – wash clutch
Clutch two – extract clutch
4 pieces, tied together by a jackshaft and belts, equals 4 speeds
Wash speed = wash motor on, extract motor off, wash clutch on, extract clutch off
Distribution/Drain speed = wash motor off, extract motor on, wash clutch on, extract clutch off
Slow Extract = wash motor on, extract motor off, wash clutch off, extract clutch on
High extract = wash motor off, extract motor on, wash clutch off, extract clutch on
Two, 7.5 second timeout relays were used during the drain sequence….when the machine was commanded to drain, the first of 2, 7.5 second relays came into play. The first one commanded the machine to “wash” clockwise til the 7.5 second relay timed out….
Then, the machine ramped to drain speed and the second 7.5 second relay came in to play. For 7.5 seconds, the machine operated in drain speed with the drain valve “closed”….the load “rides the wave of water and finds itself a place on the side of the cylinder, to balance”….then the drain valve opens as the 7.5 second relay times out.
There is another 55 second relay that keeps the machine in low extract speed when high extract is called for. You will ever see one of these 4 motor machines go into high extract out of drain speed cuz of that relay.
