As has been said not all manufactures classify their Screwdrivers in the same way. Some list them by (#) others by their Metric Size and some (Watch makers) go by a color band
For z scale these are the Phillips sizes i have found to be the most useful
#0000 = 1.20mm = (Grey) #000 = 1.50mm = (Violet) #00 = 2.00mm = (Green) #0 = 2.50mm = (Blue)
I use the "Gray" Phillips driver for the SD40 board Screws

While I do think the SP daylight paint scheme is one of the best looking paint schemes out there, I an going to have to say No I'm not interested in another SP set of Brass cars. It's been done before. If they are going to do brass cars again i would like to see some New Road Names preferably A Eastern road. Like B&O's Royal Blue, C&O, N&W, or maybe even a short line like the MA.&PA. R.R.

No the NYC was not released I believe they said there was a problem with the road numbers or something. Last I heard it was Supposed to be released as part of the 2nd run.

Will these use the same decoders -- TCS and Digitrax drop in decoders? TCS has a new decoder which fits for the SD40 and later. The TCS-1561 AZL2D5 that was to fit in the SD40-2 was Recalled due to production problems. All though Some Dealer websites may still have it listed (But Not Available) It has since been completely removed from any listings on the TCS Website.

Picking up where I left off yesterday. I Remove and cleaned all of the loco's wheels and gears. To access the wheel wipers which are mounted to the top of the chassis with a screw, the boiler body must be removed. The Boiler is held on with 3 screws. One under the front Pilot truck and 2 screws located just under the back of the cab which can not be accessed with out first removing the tender. Removing the drawbar screw from the loco will allow you to shift the tender to the side just enough to access the screws holding the boiler on. Once the Boiler was off and out of the way I also took the tender body off (4 screws on the bottom one in each corner) so I could inspect the wiring. As expected I found a few wiring issues in the tender circled in yellow the wire has broken free from the ring terminal at the bolster circled in orange wire is barely stuck to the side of the solder tab. circled in green only 1 strand of the wire is still connected to the soldered pad circled in red a melted piece of insulation hanging off the wire and the heat shrink tubing isn't even covering the bare wire. Note: This is not the first time that i have seen the insulation melted off the wires on one of these. The solder used on these connections appears to have a very low melting point. Its my guess that something shorted out causing the wires to get hot enough to melt the insulation and soften the solder to the point that the wires started coming loose. After I repositioned the heat shrink tubing and trimmed the wire ends i soldered them back in place. And With the boiler out of the way i was able to remove the wheel wiper assembly and bend them back into place. Re-checking the wiring for shorts, Re assembly and re-quartering the drivers is a job for next weekend David Attachments:

I'm next! Since I MAY have been one of the "few others" you mentioned... Any burned wires? Bring it with you tomorrow. Yup you were. and no not yet. But considering they had tender pickup, Tiest GS-3 should have ran even with out getting power from the drivers So I'm expect to find at least one broken or otherwise damaged wire in the tender. (Maybe even burned/melted like yours) David

Continuing my inspection I found that one of the wheel wipers at the rear set of drivers was bent sticking up above the wheel flange and not making contact with the wheel at all, The one on the other side was also bent slightly out of place and had some of fuzz caught up between the wiper and the wheel flange. After removing the front and rear bogies along with the gear cover plate it was easy to see that the one wiper was completely bent out of place and not making contact with the wheel at all. Well the next step is clear I will have to remove the drivers so i can clean and try to bend the wheel wipers back into their proper positions. But That's tomorrows job I'm done for tonight. David

As some of you may have read in the AZL Brass Pictures & Information Sharing ThreadTiest van Gool was having some trouble with a AZL Brass GS-3 and has asked me to take a look at it for him. And I know of a few others who are having trouble with poor or non running Brass Loco's, So I have decided to start this thread to post my findings and repairs in hopes that it may help others with similar issues. This is where we started Brass Train Experts (I am only a new member), I need some help, I have a BEAUTIFUL SP Daylight GS-3 and a GS-4. Thank you Sven for hooking me up! Issue I am having is the GS-3 that is not running. Only if I push down the back of the loco it runs for a second or so and stops again. GS-3 Not Running -HELP! Thanks! -Tiest After receiving the Loco I placed it on my test track for a test run and got the same results Tiest did in his video. As I posted in the Brass sharing thread My initial thoughts are that the wheel wipers are not making proper contact with the wheels or possibly a loose / broken wire. My next step was to place the loco upside down in a foam service tray and look at it under my Digital Microscope. The first thing I noticed was how dirty some of the wheels were (In the yellow circle) Next with the help of a home made 0.5mm fiber optic light slid in under the wheels (Circled in Red) its easy to see that when shifted to one side the wheel wiper is not making contact with the back of the wheel flange on the Front left driver (Fireman) side. For those who may not know, Yes the axles are supposed to shift side to side. With out the side by side movement the loco's would not be able to navigate the turns in the track. As such the wipers need to maintain contact with the wheels through the the entire range of movement. On the other side it appears like a bunch of fuzz and other crud caught up between the wiper and the back of the flange. David

What I'm seeing in your video is a wheel wiper issue. The wipers are not making proper contact with the wheels. Also their should be more than one wheel making contact so their may still be a loose wire somewhere in there. You can try cleaning the back of the wheel flanges. I would start with a pointed micro tipped cotton swab dipped in 91% IPA. If cleaning dose not help, It may need to be disassembled so the wheel wipers can be adjusted and the wiring checked. This is not something the inexperienced person should try, As re quartering the wheels is not easy. and no spare or replacement parts available for these brass Loco's.
The wheels sticking out to one side when not on the track is normal The leading and trailing trucks are slotted to allow side to side movement and rotation as it goes around a bend in the track.

Here we need your help: Sven, I do have one issue - the GS-3 does not run. I think it's because the back two wheels on the loco are not touching enough. When I push down on the backside of the loco it runs for a second or so but then it stops. Tested same with the GS-4 which shows no issues. Thoughts? Thanks and have a good evening! -Tiest Since you said it runs for a second or 2 when you push down on the back of it and it's recently been shipped My initial thoughts are it could be a loose or miss aligned wheel wiper, a loose/ broken wire that is not making proper contact I would start by putting it under my digital microscope and visually checking to see if the wheel wipers were making contact with the back of the wheels flanges on both sides at the same time. Their should be a tiny bit of side to side movement in each wheel set gently push each set side to side and watch to make sure the wheel wiper remains in contact with the back of the wheel flange at all times. Edited my response after watching your video's i don't think its a short hook a Z scale power supply to the track, and slowly turn it up to about 50-60% throttle (5-6 Volt) try gently pushing side ways on the cab first one way then the other. If it moves its likely a wheel wiper not making good contact with the wheels, If it dose not move use a tooth pick to gently move the wires running from the tender to the loco around a little. Try pushing the wires upwards towards the cab. If the loco starts to move you have a loose or broken wire.

I think it started back in January 4, so only about 112 days. But who counting? David Its been down Longer than that It went down right after they launched the first of the Black Friday Specials in November 2023 The site was hit with a malware attack last night. Our web guru John has been putting the pressure on the hosting company to get it resolved. I will post an update once we are back.

The Grooved notches for the flanges to sit in are set for N scale. Z trucks sit crooked unless you offset loco/cars closer to the back or front. However the Rokuhan Roadbed Track is a perfect fit between the raised area. Note I removed the backdrop and front Lexan dust cover so you can see how it looks with out aa blinding glare from the camera flash
