Hello, A friend of mine has an LGB 2-10-2 Factory fitted sound and pulsed smoke  Everytime he or I go to run it.. we find the quatering is off.. Is this a loose screw or a gear? Any help appreciated and hopefully its and easy fix..  Cheers Phil

Possibly a gear stripped? Only way to see, is to take the bottom cover off, although I've only done this with 0-4-0 and Bo-Bo locos, and never a 2-10-2....

It's a long while since I worked on one of these. The model is articulated, 2-6-4-2 rather than the 2-10-2 of the prototype. Each of the articulated drive sections has its own motor, but the motors are linked by a drive shaft with a flexible coupling to maintain quartering between the two units. I suggest you check this shaft and coupling as well as the gearing in the motor blocks.
Please do not adjust your mind, there is a fault in reality.

Neil is quite correct. If you dare try to adjust the quartering on one axle you need to check it against ALL the others - not just its truck of 4 or 6 wheels. If the loco has had a hard life, the coupling between the drive units could be worn. I am not sure if this can actually be 'out' of quarter. Are you sure the problem is with the quartering????

Yes, i'm quite sure Alan, as the Middle wheel pivot is higher than the others..

By 'pivot', do you mean the crank pin holding the motion.

So, lets understand this right. The middle wheel is further round than the others making the connecting rods not straight. That would mean that at some positions the crank pin is lower, some positions higher and sometimes might look right - is that it?

Your right - the quarting is out. Turn the loco over (use the polystyrene top piece if you have it). Unscrew 6 screws holding on the base plate. You will probably have to undo the lscrew linking the two chassis units as well. Now, very carefully, lift off the base plate with out moving any of the wheels - you dont want them all out of position. Lift the centre driving axle just clear of the gear and rotate one cog and lower into position - have a careful look along the connecting rods and see if they look straight. Replace the cover plate and screws and test. If not all OK, try turning the centre wheels the other way. If this dont do it - put it back as it originally was and get help. The guy from Bolton might be useful.
