Service intervals
« on: November 13, 2018, 12:54:47 PM »

Whereas (full size) cars state service intervals in either miles and/or months old, I have yet to find out how often in terms of age (including stored in a box) or running time hours what is the recommended intervals for servicing n gauge loco's. What would members recommend?

Depends how often/long you run your locos.  To be honest, when it needs it a loco will let you know. 

Dry high speed bearings make a screeching sound. Other than that it's best not to over-lube.

Listen out for the clicking of split gears.

Clean wheels, pickups etc. when the loco is getting jerky on clean track.



Before an exhibition I do try and check over every loco that's coming with me; give it a spin round the test track, examine for fluff and broken/loose bits, clean the wheels, a very light lube if I know I've not done that for several months to a year on that particular model. 

If I have time I also clean stock wheels before a show.

I have a little 'Service/Run' slip tucked in with the loco that lists the date run and a Y/N to show if it was oiled.

I'm quite often surprised when I look at the last run date.  :)

I think Farish state 24 hrs running for theirs and Dapol 50 hrs. My Rocrail software that I use to run my trains keeps track of running hours and flashes up a note when it’s time to have a look / relubricate, though sometimes I don’t think they need it and I leave them.

If it ain't broke, don't fix it.

The number of locos I've repaired due to over-oiling is colossal - so my simple advice would echo Nick's - wait until it's necessary.

Cheers,
Alan

Coming from the world of maintenance engineering I can tell you that the method of conducting maintenance periodically whilst not taking into account of actual usage hours/condition is quite a dated principle and can actually, as previously noted, be the cause of failures. You could run a maintenance diary as stated above with when last run and oiled etc in conjunction with obvious signs such a how it sounds compared to usual and visual inspections (which wont cause any damage to the working parts).

For example, I still have a couple poole era GF loco's that I haven't run since I was still in school, I gave them a run the other day and even though the motor is crude compared to today's standards they still worked well and sound as I'd expect them to so after visual inspection I decided to clean off the 20 year old oil where I could and apply a dash of new oil. There really isn't a set schedule as such.
