Dual 1225 Woes

Hi there folks,

Trying to sort out a 1225 I got for $20 from a gent in Bethlehem, PA last week. First, the motor needs attention. The upper bearing was apart when I got it. I took out the set screw, but the pulley is still firmly attached to the spindle and I don't want to manhandle it off. I have accidentally broken parts on turntables in the past and don't want to repeat that. I think this baby deserves an owner that will learn how she works and deal with her idiosyncrasies.

Can the bearing be reassembled so it will stay together? Or should I just get a new motor? I have a donor turntable OTW whose motor looks relatively unscathed. There are other issues, but I will make separate posts as I get to them. I need the collective wisdom of you folks to get me through this, I am in a bit over my head. But that's how I like to roll. Oh, here's some pics for you:

I appreciate any help/advice!

Oh, PS? I have the original mounting instructions and instruction manuals that don't currently exist in your archives, just wondering how to scan the 1:1 mounting template in my legal page sized scanner :o

I'm not sure the pulley was heat-shrunk onto the rotor spindle, but heating it may loosen it enough to come off if the set screw(s) is/are released.

If you need a new motor, try 'organdonorparts' in the first instance. the Dualcan site and mrow2 here are a huge help for servicing, parts (Don has pimpels, grease and so on) and a general background into these decks. The 1225 does look simpler than the earlier version (1216) so good luck.

Thanks DSJR, those are all great tips! I already am learning about this machine just by studying it and playing with the settings. I went to the dualcan site, but the link for Marty's Dual Turntable Parts is broken :'(

Plenty of threads on removing the pulley and I cover it in my booklet at length but heating and cooling it, then leverage off with an improvised tool, ok to use a little "liquid wrench" lube in the shaft maybe through the screw hole, it should lift off. Microscopic corrosion is what keeps it on, more or less. Try to save the motor but in any event don't destroy the parts.

Hi mrow2! I downloaded the pdfs in the stickies, is your booklet in there?

I got my parts 1225 from eBay today, need to take a look at that. The thing I am most concerned about is reassembling that bearing and replacing the felt washer which is nearly gone. Hopefully that is covered in your booklet I look forward to reading it. Thanks so much for the advice =D>

Hi I will send a p.m. All of the downloadable information here is good. I have the steuerpimpel and Alvania if you need those. Cheers, Don (mrow22)
