Generic Equipment: (See tables below from part 2 for specific items depending on switch type and lengths and back drive positioning) Item Cat Number BRS-SM Number Quantity Required Tweezer connection 86/ /2 1 Adj con rod 86/ Channel Rodding (18 ) 86/ /1 1 Fishbolt for Rodding 86/ /3 4 Back drive Lugs No Longer Applicable Green adjustables or Tubulars fitted Roller Assembly 86/ A 1 Fishplate 86/ /2 1 For when more than one 18 foot length of rodding is used (on triple crank installations). Back drive Crank Plates (for square based cranks only): Plate Length Cat Number BRS-SM Number Quantity Required Short (6 foot side) 86/ Long (4 side) 86/ C 2 Nuts for Mounting Cranks to Plates (for square based cranks only): Cat Number BS Number Quantity Required 3/ BS Washers for Mounting Cranks to Plates (for square based cranks only): Cat Number BS Number Quantity Required 3/ BS Rodding Roller Plate: Plate Length Cat Number BRS-SM Number Quantity Required Long 86/ Short 86/ B 1 Packing Plates (to compensate for crank plates): Back Drive Cranks: Cat Number BRS-SM Number Quantity Required 86/ B Depends on crank plate number Crank Base Type Cat Number BRS-SM Number Quantity Required Square 86/ /18F 2 Square (UIC Rail) 86/ A 2 Rectangular 86/ /8F 2 Rectangular crank bases are for existing installations only. Square based cranks are now used for new work. #Comes without sleeves, these can be ordered (one per crank) with Cat No. 86/ (BRS-SM 220/11C). Additional Sleeve for Crank when double or triple action drive fitted: Cat Number BRS-SM Number Extra Quantity Required 86/ /11C 1 (double) or 2 (triple) Depends on whether single, double or triple action back drive fitted. Quantities in these tables are based on single acting back drive. (For double or triple action; add items accordingly).

4 Specific items of equipment according to switch length and positioning: 2. Full Depth Rail and Clamplocks Back drive mounted in 6 foot on LHS Required Front RH downset 86/ /4E 1 Back drive mounted in 6 foot on RHS Required Front LH downset 86/ /3E 1 Back drive mounted in 4 foot on RHS Required Front LH downset 86/ /3E 1 Note: the 4 foot back drive on clamplocks is usually mounted so the front connection rod is connected to the LHS of the front stretcher. If not, use RH downset rod Cat No. 86/063980, the rear straight rod remains unchanged. 3. Full Depth Rail and Machines Back drive mounted in 6 foot on LHS Required Front RH downset 86/ Back drive mounted in 6 foot on RHS Required Front LH downset 86/ Back drive mounted in 4 foot on LHS Required Front RH downset 86/ /2* 25mm yellow painted band. These are used when tubular stretchers are fitted only. *If other type stretchers are used two straight connection rods are fitted instead.

5 Back drive mounted in 4 foot on RHS Required Front LH downset 86/ /2* 25mm yellow painted band. These are used when tubular stretchers are fitted only. *If other type stretchers are used two straight connection rods are fitted instead. 4. UIC Rail with Clamplocks and Machines Back drive mounted in 6 foot on LHS (Machine (if fitted) mounted on RHS) Front RH downset 86/ /2 1 1 Straight Con Rod 86/ Straight Con Rod 86/ mm Orange painted band. For use when tubulars are fitted only, instead of 86/ Back drive mounted in 6 foot on RHS (Machine (if fitted) mounted on LHS) Front LH downset 86/ /1 1 1 Straight Con Rod 86/ Back drive mounted in 4 foot on LHS (Machine (if fitted) mounted on RHS) Front RH downset 86/ /1 1 1 Straight Con Rod 86/ Back drive mounted in 4 foot on RHS (Machine (if fitted) mounted on LHS) Front LH downset 86/ /2 1 1 Straight Con Rod 86/

This does not apply if straight connection rods are fitted to the front on some four foot back drives on UIC Rail. Also the general rule of thumb for viewing connection rods to see what angle they are is to pick them up by the turn pin connection end at the correct way around and view down the rod towards the thread. Front rods connected to Tubular stretchers do not have both collared nuts, only one is used. Rods are slowly coming through with one removed and an additional plain nut fitted in its place. If an old rod is used, take out some additional nuts to compensate. Front rods on tubular stretchers have special spherical washers fitted and also on the drive rod on machines. The spherical washers are attached to the nuts for the rear connection and these must be fitted to the new rod. Compiled by F.M. Spowart Version One October 2015.
