From: Ron Rich ronnnrich@yahoo.com To: jukebox-list@lists.netlojix.com Subject: [Jukebox-list] Slow when cold Bodine motors
The story from my good, but not too long memory goes like this-- Sometime in the mid 1960's Seeburg began getting complaints about the mech not wanting to play at 45rpm when cold. At first (I understand), they "ignored" the situation. At some point, it became apparent that this was beginning to affect sales. They then came out with an "un-official fix"--which was an electrical addition plus the suggestion that the motor be removed, cleaned and re-oiled with "Seeburg oil". The electrical portion was "un-official" as they knew it would not be able to be UL approved. (It was similar to Wes' earlier suggestion). As more and more complaints came in, they decided sometime around 1966, to do a "study of the problem". They requested that their distribs. send in any motor that was having problems. They also requested a few sample Bodine motors from older models--all the way back to the model B. They further "borrowed" a few mechs from distribs that were having this problem. Short ending--It was found that ALL Bodine motors, including early ones ran slower when "ice cold", this is not noticeable in the 45rpm units, as the slow-down is less then one rpm@ 45rpm, however in the units geared at 33, the torque produced by the motor, when "auto-speeded" to 45rpm is much less. Bodine, which had assured Seeburg that the motors would be OK if geared and autospeeded to 45, supposedly also did a "study". Their answer was a redesign of the motor, which was then marked with a stamp "Al" after the KCI 42 model number ( I was told, once again, "un-officially", that Bodine admitted that about one percent of their motors had a "production defect").
Seeburg then re-suggested that on any mech having this problem, ALL grease, especially "Lubriplate" and oil be removed. All "thrust bearing" adjustments were to be checked, and re adjusted to specs, if needed. A light coat of graphite grease (NOT "Lubriplate") was to be applied to the gears, and a re-oiling with only "Seeburg Oil". Plus, the motor was to be dis-assembled, cleaned and re-oiled with Seeburg Oil. They also added a 5k10w ww resistor to the circuit, when in the "play" mode ( I think this is shown on the LS-1 schematic on up--I know it's shown on the LS-3 schematic-up). The above, although I do live in "Kahl-lee-forn-nee-ya", ain't no "torro feces"--just how I remember it--Ron Rich
