Water heaters are problematic for sure. I had one a number of years ago (before the current one) that I caught leaking after water was already moving across the floor. Luckily it was Saturday and we were home. The pans can fill up fast, too.

Based on what I've been told, at 16 years old, you're significantly into the "replace ASAP" phase, as RSJB18 noted. The average life expectancy is 8-12 years according to several sources, including Bob Villa.

Seeing that we have completely hijacked Pat's thread discussing the power-train in the new Mikado's....

I'll make one more comment/ suggestion regarding WATER HEATERS (notice the lack of the word hot)

Tank-less gas or electric heat pump units are much more efficient than a 50-70 gal conventional WH. Add in the elimination of 50 gallons + of water leaking out on the floor and they are a win-win! I plan to switch out my 50 gal conventional soon.

We now return you to your regularly scheduled program already in progress....

Thanks to the advice of Mike Reagan, we went tankless hot water this time, and we’re loving it!…..the lovely Ms. Tammy & I did it ourselves, and all went well, …..When I went out to Mike’s place a couple years ago, his guest bathroom is like the Taj Mahal of guest baths, and he showed me his tankless set up. When ours decided last night was the night, we followed suit….

Back to Dave’s L1 now, and probably enough about hot water heaters, ……before the thread goes poof,….

As I mentioned before, the worm shaft engages half of the worm wheel. The worm shaft, ( worm on the motor ) is pretty fat, so the worm shaft rides off the edge of the worm wheel. I believe this to be the source of the noise in Dave’s example,….this new design of intermediate shaft can not move laterally, so I don’t see any issues with premature wear due to that set up. On Dave’s model, and I feel the other models that complained about issues with jerking or jamming in reverse, the problem is the gear lash. As Norm pointed out, these fixed arrangements have a much more crucial gear mesh than other designs, ….To get Dave’s model as best as it can, I played around with the shim/gasket under the motor mount. In Dave’s case, .7 mm gave the best operation, and the least amount of noise……These engines will be another case by case study depending on how badly they perform in reverse, and how much gear train noise they create in motion. I’m not seeing anything to make these engines grenade themselves as we’ve seen on previous models, with similar gear box designs….So basically it boils down to a crucial gear lash. Mitigating noise, or jerky operation will require a hard look at the shim between the gear box and the motor mount……OR the lack their of, if not so equipped……I test ran Dave’s example on my rollers, sitting on my workbench top, which would be noisier than running on the layout,…..I wanted the worst case scenario, so we’ll be pleasantly surprised with the best case…..a video will follow this reply. For gasket materials, I used automotive gasket papers of varying thicknesses to get where I wanted it to be,……I will reassemble Dave’s L1 and test on the layout to verify we’ve at least “ cleaned up” this engine…..again, I’m not seeing these go into self destruct mode as long as the gear mesh is ok on your model, …the tell tale will be in reverse. They do need grease added right out the gate!!!….factor at least half a teaspoon full as a blanket coverage ……

I see it, but I can’t find the words to nicely say what I think of the neglect

It's pretty typical, at least with Lionel. I grease every locomotive out of the box.

Diesels are usually worse as they have much smaller gearboxes. Worst part is, diesels don't have a grease screw port to get the grease in so disassembly is a must.

(Playing devils advocate here) At the very least, one might guess it could be to minimize the mess. When assembling 1000 or 2000 locomotives, one fingertip of grease could stain a dozen shells.

The sound is very minimal, and almost not there. Sort of like some of the very old tinplate engines with their set up, except they produce a bit more noise. Overall this does seem to be an improvement from the old K4 issues, but Pat has made if much better indeed.

I would have thought they would have put in enough grease at the factory.  Am I missing something?????

Yeah Mark, I think on a topic from a few years ago quite a number of people had stated about the grease being light. In some cases, nearly non-existent. Pat has said a few times that any new engines should get some grease popped into them. Not exactly what you would want to be doing, but as some have also said, "get some oil and lube in your engines before running for great performance."

And you hit the nail on the head Rick, any new locomotive should get a  pre-trip inspection and lube before going into service, …..live by the creed, if it moves, it needs lube,…..a lot of folks over look things on steam locomotives like rod bolts, eccentrics & sleeves, valve motion, levers, links, you name it, …..For this job, I like 75-140 gear oil. I love how that stuff doesn’t evaporate off, it clings like mad, and hangs around where I want it for a long time!!….75-140 in a pin applicator will amaze you guys when used as a tiny drop,…..

We’ll at least the problem is easily solved. My copy didn’t exhibit any of the bad behaviors. Maybe a tad noisy. Maybe.

I haven’t disassembled mine, but will probably do so to check the amount of grease and whatnot. I wonder if all of them have gaskets with the same thickness. I’ll measure mine and report back.

I’m glad you chimed in Ryan, I seen you post your videos on the other thread, ..but it’s really hard to hear beings your track is directly on the wood, and the sounds of the rails kinda drown any noises out,….I’d like to make a suggestion, and ask you to grease yours arbitrarily, and retest, ….but you’ll have to tell us how that works, as again, your layout drowns out with resonation…..if you’re not experiencing any issues in reverse, I wouldn’t open it up yet,….I’d like to know your findings after a proper greasing,……Dave’s had issues in reverse, and quite a bit of noise in forward,….so he was either fixing it, or sending it back…..thanks!!

IMG_7326Here’s Dave’s chassis ready to reinstall in the shell,….I like super neat cable management, so I improved on Lionel’s neatness, and wrapped these harnesses into nice bundles, that should keep them neatly in order for a long happy life,…….Also note, I found the motor mount screws to be a tad short for my liking, the holes are generous, so I installed some longer 4-40 screws to prevent future strip outs if servicing is ever needed in the future…..I test ran one more time with straight DC on the motor before finally plugging back in the motor & sensor leads,…..I’m liking what I’m seeing now!!…..so far, mucho bueno!!

This would be my recommended course of actions on these engines, ….ONLY if you folks DONT want to return them back for either warranty repair, or refund……remember, if you open it, and mess around in there, you own it!!…..so only go in if you feel comfortable, and really plan on keeping the locomotive simply because you love it,…..

1. Test run a short distance straight out of the box, sounds off, in command mode if possible. Observe forward & reverse operation, both running light, and a tug of cars, running through a few speed steps. Watch for jerking or stuttering more prevalent in reverse. If no jerkiness, or stuttering is observed, and noise is LOW, then apply grease to the gear box as mentioned about 1/2 teaspoon ( it’s a pretty big gear box ) and do a thorough lube and grease job, retest, and observe results.

2. if you found jerking, or stuttering, or an overly noisy engine that drives you nuts, then you’ll need to look at the motor mount and or shim if so equipped. Measuring the stock shim(s)? will establish a good baseline for increasing or decreasing as needed…..I’ve found I had to add, not subtract.

How hard is it to disassemble diesels? Whenever I have to disassemble anything, I'm always worried about breaking it. Now that I finally finished laying track on my layout, I can actually run things and I know I need to grease all of my engines.
