Repair Lionel Type V transformer

Ken  the type V and type Z are basically the same. There are many sources that show the working of the Z and that will help you fix your V.   Lenny

I easily found stuff on the ZW, but nothing on the Z. Please let me know some of these sources.

Ken, if you are an LCCA member  you can get the digital copy of the Lionel postwar service manual which gives a complete description of the Z which matches the V. The repair manual by Greenberg also has the Z.  The Z was held over into the postwar era. If you do not have access to any of these send me an email and I'll scan the info and email it to you. My email is in my profile.   Lenny

I put a manual for the Z in this recent post: https://ogrforum.com/...c/169655768841054100 (replying on my phone so you may need to copy and paste the hyperlink,).

Your V has a different coil and the circuit breaker is an 8 amp one. I fixed up a V several years ago and it's tricky, but not difficult.

Got my replacement carbon roller and rivet, so got to work on the V today. Replaced the missing roller. Also replaced the wires to both indicator lamps. Biggest issue was at the power plug where wires had broken. Put it all back together. Controllers 2, 3, and 4 work fine. I don't think #1 roller is contacting the winding: I can't hear or feel it, but it will deliver full power when turned all the way up. Also, the green "on" light works for the first time since I've owned this.  The aftermarket green lens lights up more yellow than green, though.

Haven't decided whether I'm going to go back in to work on #1, or just accept it with 3 working controllers, which is 3 more than I had this morning. I will replace the power plug, though, with one large enough to accept an underwriter's knot.

Thanks for the resources and support. I wouldn't have gotten here without it.
