Lube for nsm sliding title mech

[jd]

Does anyone have a recommended lube for the sliding title mechanism? Looks like I have petrified lithium grease in there now. Dont want to repeat this process again in another few years if I put lithium back then find out I could have used something better.

Purchased a NSM performer grand 2000 that was supposedly "serviced". However titles immediately jammed with no title cards installed. I totally tore down the mech once I saw how crusty it was and am in total awe at how complicated it is. Cant believe this title mechanism was a commercially viable or reliable solution but it does look cool when it works.

JD,
IMHO, it was NOT "commercially viable, nor reliable", even after at least a million up-dates--improvements ! (OK --not quite a million ). But, again, neither were the Phillips CD players, either !
Last I heard--NO grease, of any kind, should be, or should have been, used -- Ron Rich

Ok thanks. All the gear pivots were grease lubed so I sparingly relubed with lithium grease after I scrubbed the grime off. Left the slides unlubed but had to clean and polish the rail again. This mechanism was a real duzy to synchronize. Not even the manual covers how to do a complete disassembly. Works much better now though.

Hi JD,
IMHO, once again, if that was the "ES4" type title holder, and did not get up-dated ( or even if it did) I hope you recall what you had to do, as you will most likely need to do it again, and again. The ES 5 unit, was a LITTLE better--but still "no cigar" --LOL Ron Rich

Lovely. Only a few main steps in case anyone else tries to totally tear down the title mech. The manual does not fully cover this process and assumes the gears never need to be removed. Mine jammed mid slide so I wasn't able to easily record positions before gears were popped off.

1) from totally apart take back shell and install 4 large gears and 3 small drive gears. Positions don't matter.

2) Assemble and install worm gears note there are 26 worm slots and 25 pages a side. Need to have all 8 worm gears oriented the exact same way with the end of thread on them pointed horizontal. Also worked out that the mold seam on the gear was vertical on mine. That leaves 1/2 a slot in the front and back and 25 centered. Ensure lower timing wheel has the peg centered in the photo sensor gate. It has a friction fit nut you can twist off with pliers to set it after the worm gears are set.

3) Install sides. Park front slide against a stop. Rear slide goes on the opposite side. No stop for rear slide. I installed the front 2 and the rear 2 pages by flexing and popping them in the front to do this alignment.

4) Rear timing gear with hemi photo gate gets installed with the gate centered on the middle photogate such that all 3 are blocked. install pages in the order recommended in the manual for a synch. (1/2 and 3/4 visible.)

5) This should leave you with a fully synched title page unit in the viewing position with the left and right pages level. Ensure the slides can fully travel left and right without snagging a page. Leave the slides parked on either side before reinstalling in the jukebox or the juke will pop out an error because it does not detect the front slide on the left or right.

Had to join forum just to say many thanks for your instructions on the rebuild of the title unit. Had one somebody had took one apart and rebuilt wrongly. Following your steps worked perfectly. Many thanks

Hi All,
Does the above apply to the ES-4, or ES-5 version, or both, of this title strip holder ? Ron Rich

[jd]

Mine is an ES 5.1. I don't know if the older ones are the same. I would imagine with the unbelievable effort somebody went through to design this title unit for the basic job it serves that it would not have been practical to make design changes over the 5-10 years they probably made these things.

Hi Gary,
Ah, didja read the above ? Is your's a -4 0r -5 system ? Ron Rich

[gm]

Hi Ron, its an ES-V, i didnt think that the title page assembly was unique to the ES-V. Any help on how to take this thing apart and fix it would be great. Thanks

[Ron Rich]

Yes--ES-4 and ES -5 were very different--in size and everything else. It's been 40 years since I did these-- don't remember much, as I hated the NSM brand at that time--(long story !) Like I axked earlier-- didja read the above posts--JD's post seems to be about the way I remember doing it--- Ron Rich

[gm]

Yeah, i did read his post, his unit was an NSM Performer, i think his may have been a bit different since my Firebird 2 is a 100 CD wall mount unit with no speakers. Looking at this title page unit and the "not so detailed" manual - doesn't say how to dissemble it to get to the jam. I hate to just start removing screws all around the case...scary, may not get it back together properly again.

[Ron Rich]

Only two of them were made--name of the phono, cabinet design, are of no consequence-- electronic SYSTEM NUMBER (ES), is what counts. To get to the jam, flex title holders, and pull---

Got it, the last title holder in the back with a cracked\broken center and edge....thanks Ron for your help and quick response !
