2mm Scale Association Instructions for Conversion of Farish 5700 Pannier Tank
Dismantling the Farish Loco
- Remove the chassis fixing screw: Located below the chimney.
- Separate the chassis from the body: Pull the front of the chassis downward and forward.
Dismantling the Farish Mechanism
- Disassemble as per exploded view (Fig. 1):
- Carefully remove brush retaining clips to avoid losing springs or brushes.
- Withdraw the top brush tube to release its feed wire.
- Discard the couplings, wheels, coupling rods, and keeper plate.
- Ensure the long wire from the top brush and the capacitor stays with the cast block if possible.
- Slide the top frame forward out of the crimped-over ears at the rear.
- Note the orientation of the magnet, usually identified by a spot on one side.
Replacing the Farish Worm
- Remove the worm:
- Screw a 1/4″ BSF nut onto the worm.
- Hold the worm in a vice with the armature hanging downward.
- Use a punch to tap the spindle through the worm (see Fig. 2).
- Fit the replacement worm:
- Cut to 1/4″ length.
- Gently squeeze onto the spindle in a vice using a spacer (e.g., an 8BA nut) to press it on as far as it will go (see Fig. 3).
Enlarging Slot for Gear
- File the slot:
- Extend the 6.5mm slot to 8.5 or 9mm, equally spaced about the axle position (see Fig. 4).
Fitting Axle Bushes
- Press bushes into side frames:
- Insert from the copper side and lightly solder using a small amount of solder paste under the bearing flange.
Checking the Thickness of Casting
- Ensure even thickness:
- Older castings were 6mm thick; newer ones have raised pads that need to be filed off flat to maintain an even 6mm thickness.
Adding Tapped Holes to Chassis Block
- Thread drills through bearings:
- Lay across the chassis block in axle slots (see Fig. 5).
- Spot through fixing holes:
- Use a 1.3mm drill.
- Remove side frames and drill with a 1mm drill from each side for 12BA tapping.
Filing Clearance for Muffs
- Attach etched filing guide/shim to cast block:
- Use the 6 tapped holes and 12BA screws.
- File axle slots to match the contour of the etch (see Fig. 6).
Clearance for Brake Hanger Support Wires
- Spot through etch holes:
- Drill to a depth of 0.5mm (see Fig. 7).
Fitting Gear
- Slide gear onto muff:
- Glue with Araldite if loose, ensuring minimal fillets.
Making Special Square Washer
- Fold layers for double thickness:
- Glue or solder together.
Fitting Brake Hanger Supports
- Assemble side frames with 0.3mm N.Silver wire:
- Solder lightly to copper surfaces (see Fig. 10).
- Separate frames and trim the excess wire.
Adding Guard Irons
- Solder or glue etched guard irons:
- Ensure squareness and concentricity of holes (see Fig. 10).
Crankpins
- Solder or glue into wheels:
- Lightly countersink rear with 1.3mm drill for space.
Chassis Reassembly
- Refer to Feb/March 2004 Newsletter:
- For help with assembling side frames, wheels, and muffs.
Motor Reassembly
- Reassemble motor:
- Use a special square washer under the 10BA frame fixing screw.
Electrical Connections
- Earthing and isolation:
- Ensure the offside frame is earthed to the chassis block.
- Isolate the nearside frame from the chassis block.
- Shorten the wire from the top brush and solder to the nearside copper surface (see Fig. 13).
Final Assembly
- Add brakes:
- Fold and attach brake shoes and support (see Fig. 14).
- Secure braking assembly with minimal solder and Araldite.
