Would appreciate some pictures from someone who has a WurliTzer 2900, of the fluorescent lamp below the selection keyboard. Would like to see its position and how the end tips are mounted. Thank you Shankar Singh

Another problem child, Wurlitzer 2810 not selecting
by Tony Miklos 13 Jul '24

13 Jul '24

I have a 2810 in for some work. Got everything fixed and testing it yesterday it suddenly stopped selecting. It was set on free play when it came in and that worked fine. (It had some funny little clip on the free play button to make it stay on.) It was working perfectly. I had tested it for some time, then suddenly when making a selection, the buttons latch in and that's it. Both latch solenoids are engaged and the associated contacts are cleaned and adjusted. I did go through the troubleshooting menu in the manual but didn't find anything. Any ideas? Thanks, Tony

Try cleaning the switches for the relays on the junction box.

LPC 480
by Tony Miklos 13 Jul '24

13 Jul '24

I put a new (used) clutch in because the old one somehow had the worm gear stripped. Often when it went to the right side and then reverses, it gets stuck and just slips. I went over the rubber stop and the reverse trip adjustments and it is working much better, I actually counted and it worked properly 100 times in a row. If I make it change direction before it gets to either end, it changes direction no problem at all, ever. (I hope Ron isn't reading this and knows that I was hitting the reversing switch by hand) :) It was acting up whenever changing from the right side to the other direction but the adjustments cured that. What remains is that if I play the last record on the right, A or B side, it then gets stuck again. Pushing the mech quickly to the left will engage the clutch and all it well until I select the last selection. Any ideas? I'm about ready to tell the customer not to play the last selection!

Good news to report! The motor shaft and drive wheel axis had no left-right/top-bottom moment. But they had push-pull movement. I replaced the turntable belt and switched over the sleeve from a newer motor shaft to replace the pitted one I had. I was surprised at the difference it made. The annoying noise was gone! Just have to remove the back-stop pawls to clean them… again… (groan…) Thanks again John!

W2900 Problems
by Shankar Singh 11 Jul '24

11 Jul '24

I am now playing this juke after a couple years rest. Cleaning all the relays and switches made it operational again. 2 annoying issues prevail- 1. Back Stop Pawl keeps sticking. I sprayed a few drops of auto parts cleaner at the pivot. It frees up for a few hours and then sticks again to cause wrong odd side selections. Any suggestions? Trying to avoid removing and washing. 2. Turntable motor noise. This noise is not heard through the speakers. But it sounds loud before and after the music drowns it out. If I push off the drive wheel from the motor sleeve, you can barely hear the disengaged motor spinning by itself. Could the arm that the drive wheel spins on have a problem? The sleeve seems pitted. I think this could have been done years ago to avoid issues from hardened drive wheel tyre. Could the belt or rubber mounts cause this? Any advice would be appreciated. Thank you. Shankar Singh

Re: Reduced tension WurliTzer vertical play lift arm springs.
by Shankar Singh 11 Jul '24

Rob, Would this be a suitable gauge for the spring stretching exercise? https://us.ohaus.com/en-us/products/balances-scales/mechanical-scales-balan… 12 oz would be about 340 g. What sort of value would it be for an unstretched spring? Thank you Shankar Singh On May 4, 2022, at 14:23, Chan Gade <chan.gade(a)yahoo.com> wrote: I first reduced the lift springs in March 1986 when I got my first W1800. The approach I’ve always used is to simply overstretch them carefully so as to weaken the force down to approx 6 oz. for the 100-104 and approx 12 oz for the 200. I over weakened a spring on a 3000 to 6 oz and it worked reliably anyway. He reason for the slight added force on the 200’s is the friction from the duckbills and more careful setting of the guide rollers. I’ve always taken a whole setup approach. Mechs are washed. Carousel removed. That involves removal of the arch and motors as well as all underside assemblies. After drying and relube the carousel in replaced and I make sure it is locked/indexed to the crank. I manually turn the large gear in reverse to allow a lift arm to just begin to enter a slot. It must be centered. I double check by releasing the backstop pawl and checking of any movement. Wurlitzer was pretty good at setting this uniformly, but I have found a cumulative shift due to variances in the carousel. Try this at several points on both A and B sides. If more than a 1/16in shift is consistently noticed, I reset that side’s backstop pawl, Here I let the duckbill enter the slot just to the point where it’s hinge in entering as well. Carefully move the backstop pawl to just engage the carousel tooth and lock it. ----Guide rollers must be able to turn freely. The old oil often causes them to get stiff or not turn at all. This will affect the last inch of lift where they help position the gap or duckbill so they don’t drag on the turning record. Wurlitzer tended to use a bit tighter gap in the rollers than necessary. I open them ‘just enough” to do their job without adding much drag. --Stretching the springs: It is pretty simple, I attach one end to a rigid item such as a steel shelf unit and, using a shop glove I pull back on the spring over it’s entire length to the point where I feel as slight “give’.. Put the spring back on the mach and with lift arm fully up, I measure the force required to pull it back down against the spring tension.. I use a simple Ohaus spring pull scale hooked to the bottom of the arm elbow. Go slow and expect to try several times till you get the desired tension.. When I was doing Wirlitzers by the half-dozen ( I really liked them) the process became quick and intuitive. Now, I’d be back to first time caution. This was just one of several mods to make the old mechs less brutal and it is especially helpful in preserving the later AC gearmotors (2700-3300) for which there is no modern replacement that I’m aware of. It would be great if someone produced new-weaker springs, but this is probably too esoteric…so as usual, we are on our own. RobNYC

Rowe CD title page Motor
by Jukebox Repairman 09 Jul '24

09 Jul '24

I have a customer with Model I CD machine. This has the vertical title pages and like most the gear in the motor has stripped. The original motor is a Merkle-Korff ( now nidec) and apparently a rare commodity. Tried calling them directly and emailing but no response. Does anyone have a spare motor they could part with? Regards Rick
