I am having fun (that is with a capital f) trying to get the flycranks and rods on a 4 wheel chassis to turn smoothly. 6 new AAs and i still have to encourage the axles to turn. What am I missing????
Hi, start with one thing at a time.
Does the motor/gearbox run freely outside of the loco?
Does the motor/gearbox run freely when it's in the chassis frames - that is with one axle in its bearings?
Does the non-powered axle run freely in it's bearings?
Quartering can be fun, but the method that I've adopted with reasonable success is to tighten up both cranks on one side, and the crank on the driven axle on the other side. Then just pinch the grub screw on the last crank so that it can move round the axle if forced, then run the motor for a few revolutions of the cranks.
If the mechanism is still a bit stiff, have you glued the bearings in place yet? The instructions on my 0-6-0 told me when 'not to do it yet' but never said when to do it 'now'. You only need one bearing slightly out of kilter to create a fair drag.
The other thing to try is to give the motor a bit of a kick with a standard 00 12v transformer, and to get the mechanism spinning enough for the brass bearings to bed down a bit.
Failing that, drop me a PM and I'll try and think of something else.
This is an IP 0-6-0 chassis
