|22253: 3MM SCALE 'NARROW GAUGE'CCU 7FT WHEELBASE|
Carriage Compensation Unit
These etched brass units for bogie vehicles provide a suspension system with the following characteristics:-
• Ability to compensate for changes in vertical track alignment and any degree of cant.
• Enhanced stability of vehicle body and bogies.
• Free running to allow scale length trains to be hauled.
They consist of an etched brass 'outside bearing' subframe which will accept standard bearings and wheelsets. The CCU is mounted on the coach underframe using a press stud which is supplied. This arrangement allows the bogie to be attached and removed easily. Alex Jackson couplings may also be fitted. To finish the bogie the modeller must provide bearings and wheelsets to the appropriate gauge and cosmetic side frames.
Brass Pin Point bearings - waisted (MJT 4009) and shouldered (MJT 4010) - are suitable for use with this CCU.
Can be used for narrow gauge bogies in other scales which require a 21mm wheelbase. The unit is designed to work with a 20mm long axle (over pin points) but with the use of shims and / or washers, a little variation in this can be accommodated.
