I am converting couplers on a friend's Bachmann GE44 from McHenrys to Micro Trains.
MT conversion chart recommends a type 001.02 052 (2004-1). Only the type 001 02 052 (2004) was in stock at my LHS, but I understand the 2004 is just the non assembled version of the 2004-1 and otherwise are identical.
MT do note that there will be a need to file some of the coupler pocket to allow the draft gear box to fit.
I have filed the pocket sides so the coupler fits width wise. However, to avoid the trucks touching the rear of the draft box, it appears that the pocket depth needs to be increased to such an extent that the screw post for the McHenry coupler also has to be removed. This means there is little material left below the front walkway to drill and tap for the MT screw.
I realize that the trucks may only swivel a small amount, and very small clearances may suffice, but am concerned too much material has to be removed to fit the coupler.
I also tried a Z scale body mount coupler removed from a 800 00 050 box car. However, the length of the draft gear box on this coupler is slightly longer than the 2004, and also interferes with the front of the trucks when they swivel.
I would appreciate guidance from any member who has done this MT conversion?
Thanks.
