Johnston road sweeping equipment can and will in many cases out last the useable life of the chassis it is mounted on. After complete refurbishment this equipment can be remounted on a NEW chassis and used for many more years. Parts that are no longer serviceable will be replaced with new Johnston parts.

THE PROCEDURE
All sweeping equipment is completely stripped apart, shot blasted, repaired or renewed where necessary and painted prior to re-assembly onto a NEW chassis of your choice.

BODY, COWL & REAR DOOR
The body, cowl and rear door often require much more work than a lot of the other equipment but this does not mean that they are not re-usable. All bodies, cowls and rear doors are completely stripped, shot blasted and repaired accordingly using the original grade steel.

This can vary anywhere between minor panel repairs for slightly dented cowl’s etc. to complete rebuilding of the whole body and cowl. For the body this will in most cases mean complete side and roof renewal along with internal vacuum tunnel rebuilding and suction and exhaust tunnelling replacement for the cowl. Rear discharge doors can also be completely rebuilt.

Once the body, cowl and rear door refurbishment is complete, they will be painted in your livery, in a low bake oven by a local company that specialises in commercial vehicle paintwork.

AUXILIARY ENGINE & TRANSMISSION
In most instances the auxiliary engine will be replaced with a NEW Perkins unit carrying a full Perkins warranty. Alternatively auxiliary engines can be fully reconditioned by a registered Perkins agent and also carry their 1 year warranty. New starter motor, Alternator & radiator along with top & bottom hoses & water & oil switches will be fitted

The fluid coupling and z-drive gear box will be fully reconditioned but can be replaced with new if required.

ELECTRICAL EQUIPMENT
Control boxes are mounted on a vertically mounted pod in the cab with the PTO and ‘Ergo’ switch incorporated alongside. The Camera monitor will be mounted on top of the control box. This means all sweeping operations are operated from one local area therefore vehicle dash boards do not have to be modified or removed to accept additional sweeping equipment switching.

In view of safety, reverse camera systems and audible reverse buzzers are fitted to all machines.
The engine loom will be replaced with a fusible link engine loom. Also resistors & relays are replaced.
Voltage upgrades are also carried out on 12 volt systems to 24 volt, to include starter motor, alternator, relays, bulbs and all solenoids.

The systems locker will be completely stripped of all contents, shot blasted, painted and re-fitted with all components, new where necessary.

HYDRAULIC SYSTEMS
All hydraulics are checked, cleaned and items replaced where necessary including internal valve bank seals. All hydraulic hoses are replaced with new, to include suction hoses, return hoses as well as pressure hoses. The hydraulic return filter is also replaced.

WATER SYSTEMS
All water hoses are replaced to include suction, return and pressure hoses. The water pump will be checked and repaired where necessary and all water jets renewed to give optimum water pressure and efficiency.
New Supa wash is fitted to incorporate front spray bar, nozzle box spray bar/s, also a hose reel & lance with twin jets.

SWEEPING EQUIPMENT
All sweeping equipment will be completely refurbished to incorporate NEW pins, bushes, motors & any other items necessary.

The WSB will be replaced with the low-pro system if not already fitted.

RUBBERS & WARE PARTS
All rubbers are replaced with NEW to include all curtains, nozzle box rubbers, nozzle trunking, top boom hose and gaiter, rear door seal, body and cowl make and brake seals & engine cowling seal. Ware mats will be relined or replaced if required.

YOUR LIVERY
All vehicles can be painted in your Company livery. All we need is the paint code you require your vehicle to be painted in and the style and size of your Decals.
