Engine can't pull 9V train

Posted by John Mycroft on September 17, 2005, 2:54 pm

Hi - my son (OK, I!) has a 9 month old 9V Express train. The engine is now
unable to pull the trucks - the motor runs fine but the wheels slip. I have
given all the truck axles a wipe with a cotton bud dipped in WD40 which has
improved things a bit. Any other tips? How about replacing the "tires" on
the loco - can I get spares from anywhere?

www.bricklink.com
there you can buy all lego you can think of in parts.

and look at the photo on the #115 photo, the locomotiv has extra rubbers for
grip, those might help too, so try find them on bricklink (under train
probably? :)

WD40 will make everything slippery.
I use an alcohol dampened cotton wipe to clean the track. Do Not use this on
the Motor wheels as it might react with the rubber on the wheels. Try to
wipe the WD40 off the wheels with dry cotton swabs

Thanks, All

I've paid a quick visit to bricklink.com - haven't found any engine tires
there yet but I could probably pick up something similar at a plumbing
supply shop. As for the rails, I have wiped them all down with isopropyl
alcohol which has removed some gunk. I dismantled the axles before applying
a tiny spot of Wd40 - didn't squirt it stright out of the can and everything
runs more smoothly.

Clean out the WD40 quickly before it dries out. Once it does, the lacquer
like substance it leaves behind will freeze up the axels as if they were
glued in. Water Displacement formula 40 was developed to remove and seal
out water from the tiles and grout in Minuteman missle silos. Once the
volatile components evaporate, what is left is hard as a rock.

I've seem more equipment ruined by WD40 than I can shake a stick at, both
irreplacable teletypes and other printers. Whomever decided to advertise
it as a lubricant should be drawn and quartered.
