[GreenKeys] M33 50hz motor...

[teletypeparts at comcast.net]

I am not sure, but I think Julien has seen the 33 work in Local mode.  I know he had the printer out to do some work and was successful in replacing the printer.  
  
If you replace the existing motor with the 181870, you may also need the start relay and capacitor.  And the gears of course and a UCC-6 as well.  
  
I will check on the start relay and cap to see if it changes with 50HZ or 60HZ.  I have the gears and motor, but it will be pricey to ship, so I will await further checking by Julien.

Hi all... 

As suspected, Julien's M33 had seen service in Europe, 
hence the 50hz mods... 

I wud recommend the best 60hz motor replacement to be 
P/N 181870  rated @ 33mhp... 

As this is the most common motor in use in the M32/33, 
pbly someone on Green keys can help Julien with this. 

I don't have any spares or wud offer one up. 

Best that the 33 not be used on 60hz AC, as it will 
run hotter & faster... 

It wud not likely print properly when connected to a standard 
110bd signal, such as a PC or from a host computer... 

However, in a local mode, wud pbly print ok, but will for 
sure make the motor run hot... 

Along with the motor, you wud also need a 181411 pinion and 
a 181420 driven gear... 

The existing fan & shroud will be fine, as the larger fan 
will just provide extra cooling. For the 60hz motor, the shroud 
is optional... 

As for the UCC I.D. tag, it may be found in one of two places... 
It may be attached to a vertical surface closest to the right 
hand side of the UCC chassis, 
or located about 4 to 5" in a rearwards direction from the 
mode switch (Local/Line), facing up...It is a small 
aluminum plate stamped with UCC type mounted on the top 
surface of the UCC chassis plate... 

As this UCC is crowded with cct boards, you may have 
to dig a little to locate it...I am sure it is there...It 
shouldn't require a major disassembly to locate it... 

Hope this all helps! 

Cheers!
