C-25 Modifications

Following my review of Accucraft’s new C-25 in Steam in the Garden magazine, I got plenty of run time and decided on some changes that needed to be made. Here is a list of my C-25 mods. If anyone is interested in a particular modification I made, please contact me off-line for photos and a detailed description.

1. Installed R/C on the throttle and reverse with HS-65MG servos and AR6000 receiver.
2. Fabricated a working headlight using a 3 mm yellow-glow LED in a cut down MagLite reflector, with the battery and switch in the cab.
3. Changed the lubricator. The original displacement lubricator had a very high rate of oil use, so I changed to an Accucraft adjustable hydrostatic lubricator (AP-21611). But this did not work because the unit was incorrectly assembled and fed no oil at all. So, I installed a Regner hydrostatic lubricator (40405), which works perfectly.
4. Reconfigured the water pump hose to the locomotive connection. I found the original design to be awkward and difficult to attach and tried to improve it by installing a quick disconnect. But this solution was also awkward and difficult to manipulate because the connection is low and space between the tender and loco is very tight. My solution was to reroute the hose above the cab floor, but still use the quick disconnect. (TD63 Miniature Quick Disconnect Male 1/8" barbed bulkhead fitting on the back of the cab. TD60 Miniature Quick Disconnect Female with 1/8" barb on the hose from the tender.)
5. Installed a Summerlands chuffer (SCAC7).
6. Installed a WeeBee pop safety valve with adapter.
7. Installed a Goodall valve.
8. Replaced the gas valve lever with a knurled knob.

Hi Carl,

I'm fascinated by your adaptation of the Regner lubricator. Only my Accucraft Climax has an adjustable lubricator (which works well) and I'd like to begin changing over my other locos. Could you post pictures of your installation? Were there any particular issues you had to resolve when installing it?

Llyn, installation of the Regner lubricator was easy. The only fabrication was to cut 3mm copper tubing, solder on the compression fittings, then bend to shape. I did not install it through the floor like the original, but stood it on the floor in the front of the cab so I could reach the adjustment knob through the front door. Also, the drain can't be used so I use a syringe to extract the grunge. I never liked draining the old way anyway since it usually made a mess. One modification I made to the lubricator was to fabricate a handle and solder it to the cap, an easy mod.

Hi Carl,

That made a very neat installation! Did the tee and connecting fittings come with the lubricator? Did you silver solder the compression fitting ferrules, or just go with soft solder?

Llyn, the tee that came with the lubricator was for 5 mm tubing, so I also purchased a 3 mm tee and used it. I silver soldered the tips with Radio Shack rosin core silver-bearing .022 dia solder, which I find very useful for little jobs like this. I used a resistance soldering unit for neatness and localized heat concentration. I used the Regner 40405 lubricator and don't remember the part number for the tee. Jason Kovac has all the parts including copper line and fittings. I had to anneal the copper with a torch before bending.

As an FYI -I am going to make up a parts kit that has everything you need as I have been doing this for a bunch of people and it will make life easier.

Also note the Regner lubricators are designed to start at 2 turns out then adjust in after running to get to the final set point. Once there no more adjustment is necessary.

For larger locomotives there is also a tall lubricator that is about 3.5" overall. Don't worry Carl I still have you down for one.

Would you still have the lubricator kit for the Accucraft c-25 live steam. I just purchase a mint condition C-25 just about two weeks ago.

As mentioned, that was a 2012 thread, and I believe Carl Weaver ('weaverc') passed a few years ago.

On my EBT #7, I ran small wires in hypodermic tube. You can buy steel hypodermic tubing on Amazon. I think mine was 1/16th, but you'd have to check the diameter of the tube on your loco.
