oldknotty Posted December 10, 2009 Share Posted December 10, 2009 Here i am back again to pick your collective brains to help me on my way :-)) I have two questions to ask and would really appreciate any advice you can offer . Firstly I have a really nice model of the Lima class 66 in Yeoman livery and i want to replace the wheels on it as it will not run on my layout with the stock ones .I have the Bachmann one and runs very well on it , the wheels are smaller and finer . What do i need to buy to fix this and from whom ?? Secondly I have a Hornby 9F that will not run for beans on anything , I really don't want to fork out for the Baccy one unless I really have to , are there any alternatives to make it run better ?? Like maybe adding weight to the loco or is the new Hornby loco driven chassis available from them on its own ?? from the railroad range , I have heard it is an easy fit ?? Anyway I need some advice here please !! Thanks martin Link to post Share on other sites More sharing options...

For the 9F you could try for a replacement chassis (no idea if available or of price but Hornby usually very helpful), OR get someone(or yourself) to build the Comet replacement with Markits wheels, Mashima Motor etc (bit expensive & exciting if you have never done chassis kits); you might find that the Baccy one is less expensive than just this chassis and drive & then use the original as a shed filler! 36E Link to post Share on other sites More sharing options...
34theletterbetweenB&D Posted December 11, 2009 Share Posted December 11, 2009 Alternative to the Ultrascales: buy the cheapest Bach 66 you can find (under ??50 from the well known Liverpool emporium, but worth checking elsewhere) and stuff the lima body with the mechanism. That way you get all wheel drive and a chassis that you know works; and a current Bachmann body plus Lima chassis combo, which you can probably sell on to defray costs further. I would suggest a similar approach on the 9F. Flog it and buy the Railroad or Bach. If the body of the 9F has been detailed or modified then the Railroad is the obvious choice for a body swap to the new chassis. Personally, go for the Bach. it's a much superior model all round...

chertsey chopper Posted December 11, 2009 Share Posted December 11, 2009 Yes...I'll second that. I converted a Margate tender-drive Hornby 9F to Loco-Drive a year before the first China-made Tender-driven batches appeared. I had to do quite alot of cutting and filing through the chassis and made a housing for the SSPP motor I used to power it just in front of the backhead, so it wouldn't be seen. The drivers were number four pair, which still kept the "air-gap" under the boiler. It wasn't difficult to do either, and once extra weight was added into the hollow boiler, and extra pick-ups were added to the drivers, she pulled along quite nicely, but after all that work, I sold her and went for the China-made versions because the detail was much better. In turn, they went too in favour of the much superior Bachmann loco drive versions of which I have two now, and they are proving a very good choice. jules Link to post Share on other sites More sharing options...

Not quite as easy as that as the lima bogie side frames, fuel tank, battery boxes and air tanks all need transfering to the new chassis, along with modifications to the sole bar (relocating components), headstock (remove 'wipacs' and remove the lifting eyes) Does make a nice model when done, but is a fair amount of work.

Thanks martin Not sure what's wrong with your 9F, or which version it is, but mine is one of the older ones - pre-China - and I wasn't happy with the running, especially through Peco pointwork. I worked a few fixes on it and it now runs well and will pull a lot. 1) cram as much lead into the tender as you can - there's room for quite a bit. 2) the back to back spacing of the tender wheels was too narrow, causing the loco to run stiffly through Peco points. Moving the wheels out on their axles will solve that, but you'll then need to add shims or washers to ensure that the gears remain in mesh. I simply glued two squares of plastikard under the tender, to force the wheels to remain in mesh - it's crude, but works perfectly. 3) as it stands the loco picks up from one half of the loco chassis and the other side of the tender, which (since there are only two functioning tender axles) is not really sufficient for reliable running. Add additional pick ups to the loco chassis, and then hard-wire through the tender, so that you're not relying on the drawbar connection. China made 9Fs have pickup from both sides of the chassis so the existing arrangement should be fine. Once you've got your 9F running well, the body can be made to look pretty good with some additional detailing. Link to post Share on other sites More sharing options...
APOLLO Posted December 11, 2009 Share Posted December 11, 2009 I have 4 versions of the 9F 1. The first one, Hornby silver seal from late 70's. Best of the lot, haulage & running wise. Tender drive with traction tyres on all tender drive wheels. All loco driving wheels pick up, 2 permanent wires to tender. 30+ years old & pulls 'owt I put behind her, slow speed also superb 2. Second version similar, but now 2 tender wheels pick up, one side on the loco drivers also, which have the electrical feed to tender via loco / tender coupling. Not anywhere near as good as above, but you can fit lead weight on top of the motor under the coalspace, AND fit another pick up wire from motor to loco chassis, giving ALL loco wheel pick up (& 1/2 tender also). Fit new traction tyres with a touch of superglue (so they don't move). This now gives an acceptable performance. 3. Third version is a standard Bachmann. Fine loco with brilliant haulage & running - BUT not as good as the first one above. 4. Fourth - I have a couple of the new railroad 9F's. Loco pick up & drive. Haulage is good. Better than No2, but not as good as the Bachman, and nowhere near as good as No1. A bargain though at ??54 from hattons - 2 railroad 9F's for the price of one baccy - a no brainer. VERY little room in loco body for extra weight, even less if you fit a decoder. If yours is a no 2 type, try the extra weight & wire. It helps alot. (I permanently couple mine to a Baccy Sulzer type 2 in front - They haul my 10 x 100T oil train (as in Stanlow - Leeds, etc) Brit15 Link to post Share on other sites More sharing options...
oldknotty Posted December 14, 2009 Author Share Posted December 14, 2009 Found the fix for my Hornby 9F running problems . The gears were not meshing with the wheels as the wheels were way out of gauge and if put into gauge would not make contact with the motor gears .So I added a few washers to the axles and re-gauged the wheels and bingo perfect runner !!! Hope this may help some one else in the future :-)) STill need to replace the wheels on my 66 though any ideas for a straight swop with the Lima ones ??
