RMweb Gold chuffinghell Posted July 31, 2018 RMweb Gold Share Posted July 31, 2018 (edited) I've recently bought a virtually new Hornby 61xx and it has a side to side waddle (it appears to pivot left and right about the central drive wheels) After looking at other posts about other similar problems, the issue of quartering has come up a few times I've contacted a Hornby servicing/repair centre and they've told me that its unlikely to be the quartering because if it was this would cause a catastrophic fail? I appreciate that a rolling road exaggerates these kinds of issues but I wondered if its worth me looking at the quartering of the wheels myself as I'm assuming its just a matter of making sure the wheels are at 90 degrees to each other on the opposite side.........unless I'm missing something?

Nick Gough Posted July 31, 2018 Share Posted July 31, 2018 Is it missing the traction tyre from the rear near side driving wheel? I've just bought an Airfix version with a similar issue caused by that. Link to post Share on other sites More sharing options...

Many thanks for your response It's a later Hornby 61xx, I don't they have traction tyres Edited July 31, 2018 by chuffinghell Link to post Share on other sites More sharing options...
RMweb Premium John Isherwood Posted July 31, 2018 RMweb Premium Share Posted July 31, 2018 Many thanks for your response It's a later Hornby 61xx, I don't they have traction tyres Most unlikely to be quartering - more likely excess side-play on the front and rear drivers. Peco fibre washers with a segment cut out, or C-clips, pressed onto the axle between the back of the wheels and the frames should cure it. Be careful though, it's not easy to remove them if you overdo it and jam up the wheels. Regards, John Isherwood. Link to post Share on other sites More sharing options...

I'll have a look at that, thanks John Chris PS I bet that wont stop it sounding like a tractor though Edited July 31, 2018 by chuffinghell Link to post Share on other sites More sharing options...

Hi John Stupid questions 1) Would it better to leave a little side play or remove it all together (being careful not to jam up the wheels of course) 2) Is it better to just apply the washers to just the front and rear drivers leaving the centre axle to 'float' Many thanks Chris Link to post Share on other sites More sharing options...

DCB Posted August 1, 2018 Share Posted August 1, 2018 The Hornby 61XX is a bit of a lottery, we have 1 which runs nicely, 1 which runs after a fashion, 1 which waddles like a duck and is permanently being fiddled with and two Airfix beasts about which the least said the better. The basic Airfix / Hornby chassis is awful. It has a cast chassis with square axle holes and with production tolerances and wear the axles only bear on a tiny amount of the chassis and slop around furiously. I would resist the urge to take the chassis apart as getting the pick ups back in place afterwards is challenging. I would check the rods are straight and are not binding, and the cross heads move freely in the slide bars, drop of peco electrolube maybe? If its new give it an hour of running. If you don't have a continuous run buy a circle of set track and run it on the lounge/bedroom/garage floor. Vacuum up first to get rid of the fluff. Avoid the kitchen and don't ballast the track. Spacing the axles to reduce end float sounds good, split washers sounds dodgy to me but a guy on here suggested using plasticard dummy frames behind the wheels to reduce end float. Unfortunately he used white plasticard but Black should work. Bushing the axle holes would cure the issue if you could file the holes out evenly. Probably need Romfords to get the quartering right and then fitting the drive gear would be an issue. I have a Hornby 61XX and an Airfix 61XX in bits on my workbench as I write. Sorely tempted to stick them back together and put them n ebay as non runners, lets someone else have the hassle Our Hornby 61XX sit on shed looking pretty. I have a Farish 81XX on a re wheeled Triang Hall chassis which runs beautifully, and a Wills 61XX with Romfords and an X04 which also runs very well and the two have shared banking work on the layout for 30 odd years. We also have a Bachmann 93XX which runs beautifully but wont pull the skin off, and thoughts on transplanting the Bachmann chassis to the Hornby Body have crossed my mind on a number of occasions. 93XX and 61XX chassis in full size were pretty much identical forward of the back of the back wheel.

Regards, John Isherwood. Thanks John Your suggestion has done the trick Now all I have to do is justify running a 61xx on a branchline I may have to refer to rule #3 Chris Edited August 2, 2018 by chuffinghell Link to post Share on other sites More sharing options...
