My N gauge Dapol A4 comes with a sheet saying the motion and gears needs oiling, though, somewhat inconsistently also says it has been "factory lubricated for 30 hours use".
How important is this oiling and why do Farish not recommend it if it is so vital ?
Anyway, I decided to undertake this oiling this morning but straightaway encountered a problem.
The keeper plate needs to be removed and that is held in, at one end at least, by a screw (magenta arrow in picture). However, that screw cannot be removed unless the plastic "brake rigging" is removed first. No instructions are provided as to how that should be done, and (not wanting to damage even more of the loco*) thus I have posed these questions :

How should the plastic brake rigging (red arrows) be removed ? Does it just lever up without risk of damage ?

Similarly for the keeper plate below it (green arrows)

* I love the detail on the Dapol loco but it is far less robust than the Farish locos I already have. Partly because of its constant derailing it has already been damaged in at least two places (blue arrows).......
Note the bogie wheels have been changed for "pizza cutters" as a result of the aforementioned derailing ! Also the front coupler has been removed to further minimise the chances of derailing (and also improve its looks ! ).

Whoa!

The normal understanding of 'the motion' on a steam model is the outside rods; and specifically what needs a tiny - very tiny - occasional dab of light oil is each moving joint and the slide bars to minimise wear. (Experience from OO*, I go around the motion joints every couple of months, the locos accruing about 30 hours running over that time period; and this works well enough that locos that have had this treatment over 20 years are still all in one piece.)

And further: generally no need to take the keeper plate off in my opinion. I would hope that the mechanism has a supply of light grease, adequate to keep it running well for many years. (Experience from OO*, grease lubrication in steamers is good for up to 5 years, and in centre motor twin bogie drives I have a 30 year old mechanism still running, never yet required a relube. What with N gauge being an eighth of the mass of OO, I'd gamble on never looking inside unless there are indications - slowing, 'audible complaint' - that attention to internal lubrication is required.)

*Experienced N gauge operator's advice may well differ, and should be given priority. HTH
Well spotted, I should have been clearer, it is also the drive gears that apparently need oiling. I have clarified that now !
