T6 and T7 Series Vane Pump Cartridge Kits
Cartridge kits for T6 and T7 series mobile vane pumps covering T6C T6D T6E T6CC T6DC T6DD T6EC T6ED T6EE and T7B frames.
Product Overview
Mobile pumps live a harder life than industrial ones. Dust gets past a tired breather, the oil runs hot in summer, and the drive shakes. The cartridge takes most of that wear, which is why a kit is usually the right repair for a T6 or T7 frame. Our kits cover single, double and triple frame sections and go in without disturbing the mounting or the power take off drive.

Key Benefits
- Puts a vehicle back on the road in hours rather than days
- One kit per section, so a double pump can be repaired on one side only
- No change to the power take off drive or the guard
- Priced so a repair makes sense on an older vehicle
Application Scenarios
- Tipper and hook lift pumps that have lost lifting speed
- Sweeper and municipal vehicle hydraulics
- Truck mounted crane circuits
- Agricultural trailer and spreader drives
Who It Is For
- Fleet workshops and mobile service engineers
- Truck body builders
- Agricultural machinery dealers
- Distributors serving mobile hydraulics
Problems It Solves
- The tipping body has become slow and the driver is losing time on every load
- Dust has entered the system and the cartridge has worn early
- One section of a double pump has failed and the other is still good
- The original kit is not available locally
Technical Features
- Rotor and cam ring hardened for mobile duty
- Vanes matched to the rotor slot
- Kits available per section on double and triple pumps
- Cartridge seals included
- Packed oiled and sealed for storage on a service van
Specifications
Performance figures depend on the exact variant, so we confirm them against your model code rather than publishing a number that may not apply to your pump.
| Kit contents | Rotor, cam ring, vanes, plates and pins |
|---|---|
| Frames | T6C T6D T6E T6CC T6DC T6DD T6EC T6ED T6EE and T7B |
| Sections | One kit per pump section |
| Seals | Cartridge seals included, shaft seal kit separate |

| Packing | Oiled and vacuum sealed |
Materials
| Cylinder blocks | Case hardening steel with a sintered bronze running face, bonded and machined after sintering |
|---|---|
| Pistons and shoes | Case hardening steel with a bronze shoe face, swaged and hydrostatically balanced |
| Valve plates | Bearing steel or bronze faced steel depending on the frame, lapped to a mirror finish |
| Drive shafts | Alloy steel, carburised and hardened on the spline and bearing seats, ground on centres |
| Vanes and rotors | High speed tool steel and case hardening steel, hardened and ground on all working faces |
| Cam rings | Bearing quality alloy steel, through hardened then profile ground |
| Seals | Nitrile as standard, fluorocarbon or polyurethane on request for hot or fire resistant fluid duty |
Manufacturing Process
- Turning and millingBlanks are turned and milled from certified bar and forging stock on CNC machines.
- Heat treatmentCarburising, quenching, tempering or nitriding to the route the original part uses.
- GrindingBores, spline seats and running faces are ground after heat treatment so distortion is removed.
- Lapping and superfinishingValve plates, shoe faces and block faces are lapped so the pair seals under pressure.
- InspectionDimensions, hardness and surface finish are recorded against the drawing on a sampling plan.
- Assembly and testComplete pumps are built, run in and tested for efficiency, leakage and noise before packing.
Quality Control
- Incoming material certificates are checked against the grade called for on the drawing.
- Hardness is measured after heat treatment on every batch and recorded on the batch card.
- Critical bores and running faces are gauged against the drawing tolerance, not against a sample part.
- Mating parts are matched as a set so the block, shoes and valve plate run in together.
- Rebuilt pumps are bench tested for volumetric efficiency, external leakage and sound level.
- Parts are cleaned, oiled and vacuum sealed so they arrive without surface rust.
Certifications and Documentation
Supplied on request with an order. We do not claim approvals we cannot evidence.
| Material certificate | Mill certificate for the steel grade used in the batch |
|---|---|
| Hardness report | Surface and core hardness readings after heat treatment |
| Dimensional report | Measured values for the critical features named on the drawing |
| Test bench report | Flow, efficiency, leakage and sound readings for a rebuilt pump |
| Packing list and photographs | Carton contents and photographs of the packed goods before shipment |
Customization Options
- Shaft and splineKeyed, straight or splined shaft ends built to your sample or drawing.
- Port and mountingFlange, thread and mounting pattern matched to the pump already on the machine.
- Seal materialNitrile, fluorocarbon or polyurethane for hot oil, fire resistant fluid or low temperature duty.
- Rotation and displacementLeft or right hand rotation and the displacement code your circuit was set up for.
- Marking and packingNeutral packing, your own carton artwork and your own part number laser marked on the part.

Use Guide
- Park the vehicle level and disengage the power take off before starting.
- Catch the oil from the pump and cover before it reaches the chassis.
- Check the housing bore for scoring before fitting the kit.
- Renew the shaft seal, then refill and bleed with the body raised slowly.
- Change the return filter and check the breather before the vehicle goes back to work.

Frequently Asked Questions
Can one section of a double T6 be repaired on its own?
Yes. Each section takes its own kit and the other section can stay as it is.
How do I read the T6 code?
The letters give the frame and section count and the digits give displacement. Send a photograph of the nameplate and we will read it.
Is a T6 kit the same as a T7 kit?
No. The T7B is a different frame with its own cartridge.
Do kits fit both rotations?
The cartridge is fitted the correct way round for the rotation of your pump. Tell us the rotation and we will confirm.
Can I stock kits on a service van?
Yes. They are packed oiled and vacuum sealed so they keep well in a van locker.
Send Us the Model Code and We Will Quote
Tell us the model code stamped on the pump, the quantity and your delivery port. A quotation with lead time usually comes back within one working day.
