These are common items on 384E's up to 400E's and beyond. My question is if the Plunger Pin and Plate are not tightened and seated correctly, can it cause the worm and drive gears to slip? Are there any tips/tricks when putting these back together after greasing gears?

Joe,

I would like to help you, but you need to clarify. I can only assume that you mean the pick-up plate on the "bild-a-loco" motor. The plate needs to be firmly seated in order to properly retain the wheel bearings and assure proper mesh of the gears. There is no worm gear unless you are asking about modern reproductions.

From the bad ones I've seen, it's less of a design flaw and more not greased well. The group I run with know you never do more than a test run before adding Red n Tacky.

Steve,

What do you use as a rule of thumb for greasing? About 30 minutes run time?

I usually only do a lap or two to test the loco and electronics. That way if there is an issue, I can return it as received. Once the test is done, The collector is removed, grease and oil go in. Never had an issue.

By the way, I enjoyed our visit Sunday. Same place next year maybe? I did not buy much, but got a few cool pieces.

Are P3 locos immune from this design flaw? Does this issue affect O gauge engines, tinplate or otherwise?

All MTH locos use brass worm driven gears. The loading of std gauge motors places greater stresses on the worm gears and the lack of a gearbox limits the amount of grease that could be used.  A harder material might be better if it doesn't sacrifice the motor's gear.

Thanks Jon,

I may have to buy a box of these little gems.

Steve,

Is this Red and Tacky #2? How often do you apply? I have always used White Lithium Grease.

Joe

Joe

Yes, #2. If an occasional runner, once a year or so. For those that I run a lot at shows, every couple of outings because by then it will have 10-20 hours on it.

Steve,

Been looking for this grease, only to find the cartridges for the grease gun. Was hoping to find a smaller container, like a pint can with screw on lid. Only to find on amazon in the UK.

Joe, I bought the cartridge type. I put it in a grease gun, then put the tip of a compressed syringe up tight to the grease gun and pump the grease in, filling it while it pushes the syringe plunger back.    Filling this way keeps air pockets out. I keep a couple of syringes handy, some at the bench and some in my travel kit. Won't run out for a long time.

Here's where I got mine, it came in a couple days.  Smallish jar with a screw top. Will no doubt last a lifetime.Doesn't seem to come in anything smaller. There are many other listings as well.

Thanks Steve,

You are so resourceful. I had not even thought of that. I think I have seen the syringes with the curved plastic tip that narrows at the tip. I think if I bought the cartridge it would probably las forever, unless it dried out. I will give it a shot.

 

Thanks,

Joe
