hier ein interessanter Beitrag im RMweb zu dieser Lok, Fiona von Golden Valley Models spricht über die Herstellung der Janus:
Zitat von http://www.rmweb.co.uk/community/index.php?/topic/105523-oxford-diecastgolden-valley-ye-janus-0-6-0de/?p=3093195Hi all. There are some really interesting points raised here and thanks for everyone’s contributions. We try to work closely with manufacturers and get comments if any questions are raised. I’ve been in touch with Fiona at Golden Valley Hobbies who commented:
“Like any product there is an expected failure rate – from my 20 years as a retailer and importer it runs at around 1% . The Janus return rate since launch in September is hovering at close to 0.25%. Partly because it’s designed to be a simple model with few parts to fail, or get damaged and partly because every loco is test run at the Oxford Diecast factory before they are shipped.
Anything which is reported as faulty is returned to us at my cost, and inspected and repaired/replaced.
The faults so far split into the following:
1) Damage post manufacture – e.g dropping, opening or more often finding the insides filled with carpet fibres and hair! 2) Slow/stalls – which is mainly due to dirty wheels or pickups, but on one model was a bent pick up. 3) Burnt out capacitor due to running the model on half wave settings – using 1960/70’s H&M controllers in the main. 4) Reverse running (more of this later) 5) Missing second flywheel (as follows)
Point 5 - The loco CAD and design was for one flywheel fitted after and slightly above the motor on the driveshaft. There was never a plan for two flywheels.
We’ve been sent some photos and now realise that a modeller has mistaken a universal joint as a second flywheel. The simple answer is that during the manufacture of the first model the factory decided the centre of gravity was too high. They reengineered the motor/shaft assembly so that the flywheel could be moved from above the motor, to below it, replacing the universal joint. This has no impact on the smoothness of the drive but does reduce the risk of wobble when entering corners at high speed.
This brings us on to Point 4. During the analysis and trial to make the change, at some point one production line misunderstood, and simply reversed the motor on the shaft – but failed to switch the +ve and -ve power feeds. So, on a very small quantity of models the loco runs backwards compared to other models on a layout. This problem can be resolved if converting to DCC by changing the CVV setting for direction. On DC the fault was also simple to fix. As all power from the track passes through the DCC Socket and blanking plate, we simply specified that the factory needed to make a new blanking plate with the +ve and -ve feeds deliberately crossed over.
Any owner with a reverse running loco has been sent one of these blanking plates free of charge and it immediately solves the problem.”
