Bachmann Brassworks shunters

[blueeighties]

Has anyone carried out any DCC fitting to Bachmann Brassworks shunters? I have some in the workshop which have been fitted with 00 chips and are very poor runners. Not sure if it's underpowered chips, or a poorly performing chassis.

Zimo MX645 works perfectly for me.

When you say poor runner, do you mean slow top speed or hesitant? Please explain more.

Hi Norman. Hesitant, seems to struggle a bit to get going, which I thought was lack of power. However it also seems to bind a bit, which makes me think it's more chassis related.

Hi

Seems to be a mechanical issue - pickups/bearings etc.

Try running it for an hour or two on a rolling road perhaps.

Or strip down and check all for fit and function.

My one runs faultlessly on speed step 1 - just crawls.

Happy to report I now have it running like a dream on speed step 1. A tiny amount of lubrication to the drivetrain, but lots of fiddling with the speed curve and emf settings have sorted the rest.
