malcolmy Posted March 2, 2010 Share Posted March 2, 2010 Hi, I have been looking for a guide on how to fit a chip in a Bachmann Std 4 2-6-4T. I can't even work out how to get the body off! I seem to recall a thread about it in the past, but I haven't mastered the search tools on here, and it may have been on the old forum anyway. Thanks in advance.

RMweb Gold RFS Posted March 2, 2010 RMweb Gold Share Posted March 2, 2010 There are 5 small screws as indicated in the assembly diagram: a magnetized screwdriver will make removal (and replacement!) very easy. As for a decoder the TCS DP2X-UK fits with no problem at all as there's no wiring harness so it just replaces the blanking plug with no clearance issues.

malcolmy Posted March 3, 2010 Author Share Posted March 3, 2010 Hi, Thanks for the response. Unfortunately I don't have the assembly diagram. I checked the Bachmann website, and there isn't one there either. Obviously there are numerous screws underneath that could be the five in question. I tried undoing two above the rear pony truck axle, two into the side tanks accessible between the leading and centre drivers and all three central screws above the front pony truck. The body still seems secured to the chassis. The rear section moves maybe 1mm away from the body, but the front is still secure. This loco has lots of pipework, so I don't want to try 'forcing' it as given my luck I'll damage it! Please can someone enlighten me as to what I'm doing wrong. It shouldn't be this difficult!

RMweb Gold RedgateModels Posted March 3, 2010 RMweb Gold Share Posted March 3, 2010 The Standard 4 tank assembly drawing is an illusive creature, I bought a CD full of such things years ago off eBay and guess which one is missing? If I ever get my hands on one it will be in the scanner faster than you can say "copyright" Link to post Share on other sites More sharing options...
RMweb Gold RFS Posted March 3, 2010 RMweb Gold Share Posted March 3, 2010 This gives you a bit more info - look for 32-350. I don't have my 4MT any more but there were 5 screws as documented here. http://www.Bachmann.co.uk/service/body_removal.php Link to post Share on other sites More sharing options...
Butler Henderson Posted March 3, 2010 Share Posted March 3, 2010 All assembly diagrams should be on Bachamnns web site at http://www.Bachmann.co.uk/service/assmbly.php However they seem to have deleted the 4 tank from the list whilst keeping both versions of 4-6-0 on it. A quick look up the cat nos gives the service sheet pdf for the tank as being http://www.Bachmann.co.uk/pdfs/32-350.pdf Link to post Share on other sites More sharing options...
Carnforth Posted March 3, 2010 Share Posted March 3, 2010 Malcolmy I've just scanned mine so if you want to PM me your e-mail I'll send it to you. The 5 screws are indicated by dotted lines.Don't forget the speedo cable!! Steve Link to post Share on other sites More sharing options...
malcolmy Posted March 9, 2010 Author Share Posted March 9, 2010 Hi chaps, Thanks for all your help. My error was that the boiler splits from the front splashers - I hadn't realised that so was trying to part something that wasn't supposed to come apart! Anyway, all running now, with a TCS DP2X-UK installed. Link to post Share on other sites More sharing options...
Butler Henderson Posted October 21, 2012 Share Posted October 21, 2012 (edited) Having acquired a second example I found a normal sized decoder (a Lenz standard) will fit on its side in the plastic recess motor side of the socket, with the wiring end of the decoder towards the motor any excess wire length can be wrapped up in the recess. There was no need to undo the speedo cable as it is all part of the chassis and the pipework on the firemans side easilly unplugged from the body. My other one now has the same decoder in it freeing up a DP2X-UK for something less spacious. Edited December 1, 2018 by Butler Henderson Link to post Share on other sites More sharing options...
Brober Posted March 2, 2019 Share Posted March 2, 2019 Hi there, Help needed please. Have removed (eventually) the 5 screws retaining the body of the 32-359A but can't release the body until the speedometer pipes(?) are also removed. Could someone tell me how to remove these pipes without breaking them. Many thanks Link to post Share on other sites More sharing options...
34theletterbetweenB&D Posted March 2, 2019 Share Posted March 2, 2019 (edited) The representation of the speedo link to the rear driving axle is released by undoing the slotted head screw that serves as a crankpin. So far, so simple. When it comes to reassembly be prepared for some careful tinkering to get the crank to which the speedo cable is attached positioned 'just so'. There are a pair of cast dogs or lugs to engage in a slot to guide you to something like the right position, but it usually needs a few tries at setting until the loco runs smoothly. Customer feedback on this device (also fitted to the BR std 5MT 4-6-0) led Bachmann to leave this feature off all future models that could have had speedo drives represented. Edited to add, reseating the body at the front end is often awkward too; the mechanism needs to be inserted vertically drop out, drop in style. If it doesn't go in cleanly and leaves the front of the loco too high, remove the mechanism and restart. (This model was an early introduction in Bachmann's series of 'Blue Riband' OO models. A measure of how they improved with experience is their Fairburn 4MT 2-6-4T introduced a half dozen years later. Has all the assets of the BR std equivalent in that it looks right and pulls well: and there are just three easily accessible body securing screws, and the mechanism is then a breeze to remove from and replace in the body.)

Brober Posted March 3, 2019 Share Posted March 3, 2019 Thanks 34 for the detailed answer. Now have the speedometer assembly off (will see if the issue of reassembly appears in due course) but have now found that there is a pipe and valve assembly on the opposite side to the speedometer that is preventing removal as it is fixed to both the chassis and the body. Any tips about how to remove this without damage? Link to post Share on other sites More sharing options...
Butler Henderson Posted March 3, 2019 Share Posted March 3, 2019 Think the pipe and valve assembly pulls off or can be moved out of the way ; the first one I did I had equal problems getting the thing apart and I am not convinced I have refitted that assembly right. As I have posted before once apart I realised that with one internal body fixing screw undone and removed the whole of the boiler top and cab front and roof is a single piece which is then held in place by the front body fixing screw making access to the decoder socket etc far simpler - downside is that some boiler fittings may initially fall off at the first removal of that body part and need refixing and the cab roof may have a slight gap to the cab rear. Its annoying that the body fixing screw I took off is only slight off line of a bolt through the chassis and with a little more design work it could IMO have been made so that two screws undone would allow the boiler top to be removed saving on all the problems in accessing the interior.

Brober Posted March 3, 2019 Share Posted March 3, 2019 Thanks BH. It looks as if the pipe and valve assembly is fitted to a side lug. I tried pulling on it to no avail and I didn't want to try and force it off in case it just snapped! I will try again and see if it comes free. Failing that i think it may be a case of cutting some pipes to release the body and glue back once I have fitted the decoder. Link to post Share on other sites More sharing options...
Ruffnut Thorston Posted May 1, 2019 Share Posted May 1, 2019 (edited) There is some information about removing the body, including the injector pipes, in my Ffrwd Locks thread. This includes gaining access to the cab for fitting the crew, etc.. https://www.rmweb.co.uk/community/index.php?/topic/61184-ffrwd-locks-br-wr-north-wales-near-wrexham-c1952/&do=findComment&comment=872064 Edited May 1, 2019 by Sarahagain Link to post Share on other sites More sharing options...

The bracket under the cab that carries the injector pipework etc should be fixed to the body so that it all comes away together, but glue seeps down onto the chassis ....... 1 Link to post Share on other sites More sharing options...
