Boiler pump gearboxes have been supplied over 50 years for boilermakers to marine boilers. The boiler manufacturing companies have changed name several times but include the following trade names:
Stone Platt (Crawley)
Stone International
John Stone Deptford
Stone Boilers
Babcock Robey
Wellman Robey
The most common type of gearbox is the 3¾ inch worm reduction gearbox and often takes the reference type 66212 or M8327. They are to be found in certain classes of warship.
The gearboxes were originally manufactured by Stone Wallwork and then subsequently by Shackleton Gears, Babcock gears and B&F Carter. As Shackleton Engineering we own the drawings and records for these and all other Wallwork gearboxes.
We can supply genuine spare parts, typically as follows:
Kit of bearings and seals
Output shaft
Worm and wheel
New complete gearboxes
