7135-110 Repair Kit: CAV DPA Injection Pump Specifications, Parts & Compatibility
The 7135-110 Repair Kit is an aftermarket gasket and seal kit for compatible CAV DPA rotary distributor diesel injection pumps. It is primarily intended for pump servicing when aging seals, O-rings, gaskets, and related sealing components need replacement.
Unlike a complete injection pump overhaul kit, the 7135-110 focuses on the sealing system rather than replacing the hydraulic head, rotor, pumping elements, governor, or advance mechanism. This makes it particularly relevant to workshops and parts distributors maintaining older mechanical diesel fuel systems.
Common identification numbers include 7135-110, 7135110, and CAV7135-110, while some aftermarket catalogs also use cross-reference numbers such as 9059041A, 9059-041A, 9059156, 9059-156, and 1987240106. These references should be verified against the actual pump before ordering.
1. What Are the Specifications of the 7135-110 Repair Kit?
The main product specifications can be summarized as follows:
- Repair Kit Number: 7135-110
- Alternative Identification: 7135110, CAV7135-110
- Pump Family: CAV DPA rotary distributor injection pump
- Product Type: Injection pump gasket and seal repair kit
- Repair Scope: Sealing-component replacement
- Common Pump Configurations: 3-, 4-, and 6-cylinder DPA pumps
- Common Drive Arrangement: 3-bolt drive
- Possible Additional Seals: 2 × 5393-252R for certain keyed-shaft configurations
- Application: Agricultural and industrial mechanical diesel engines
- Product Condition: New aftermarket repair components
The kit is commonly associated with different DPA pump configurations rather than one single injection-pump model. For this reason, the pump identification number remains more important than the equipment model alone.
Some aftermarket suppliers may package the components differently, so the exact parts list should be confirmed before purchase.
Common Cross-Reference Numbers
Depending on the catalog, buyers may encounter:
- 9059041A
- 9059-041A
- 9059156
- 9059-156
- 1987240106
These should be treated as cross-reference identifiers, not as proof that every kit carrying one of these numbers has exactly the same contents.
2. What Parts Are Included in a 7135-110 Kit?
The 7135-110 Repair Kit is designed around the sealing points of a compatible DPA injection pump. Depending on the supplier and version, commonly supplied components may include:
- Pump body gaskets
- Cover gaskets
- O-rings
- Shaft seals
- Sealing rings
- Copper washers
- Other small sealing components
These components are used when servicing sealing points that have deteriorated through age, fuel exposure, heat, or long-term operation.
What Components Are Outside the Kit?
The 7135-110 should not be selected as a complete internal rebuild kit.
It does not normally replace major precision components such as:
- Hydraulic head and rotor
- Pumping elements
- Governor components
- Advance mechanism
- Drive-related components
- Other internal wear components
If inspection shows damage or excessive wear in these areas, additional repair parts may be necessary.
This distinction helps workshops choose the correct repair scope before disassembling a pump.
3. Which Injection Pumps Are Compatible With 7135-110?
The 7135-110 Repair Kit is commonly associated with CAV DPA rotary distributor injection pumps used on 3-, 4-, and 6-cylinder diesel engines.
A 3-bolt drive is a commonly referenced configuration, but the drive arrangement alone should not be used as final compatibility confirmation.
Before ordering, compare the actual pump against these points:
- Complete pump identification number
- CAV/Lucas/Delphi DPA configuration
- Cylinder count
- Drive arrangement
- Shaft type
- Existing sealing arrangement
Some keyed-shaft DPA pumps may require two additional 5393-252R seals. Whether these seals are necessary depends on the specific pump design.
For this reason, a reliable compatibility check should start with the injection pump, not simply the tractor name.
4. What Equipment Uses a 7135-110 Compatible DPA Pump?
The 7135-110 application range covers many older agricultural and industrial machines equipped with compatible CAV DPA pumps.
Commonly referenced equipment manufacturers include:
- Ford
- Massey Ferguson
- John Deere
- Case
- David Brown
- International Harvester
- Long
- Allis-Chalmers
- IMT
Examples found in aftermarket application references include Ford tractor families such as the 2000, 3000, 4000, 5000, 6000/6600, 7000, 7600, 7700, 7810, and 7910.
Massey Ferguson references include selected models from the 35, 50, 65, 135, 150, 165, 175, 180, 230, 240, 245, 265, 275, 290, 390, and 399 families.
Selected older John Deere 20-, 30-, and 40-series tractors and related industrial equipment are also referenced in aftermarket application information.
These equipment models should be treated as application references rather than automatic fitment confirmation. The same tractor family may have different engines, replacement pumps, or production configurations.
5. What Does the 7135-110 Repair Kit Do for a DPA Pump?
The main function of the 7135-110 kit is to restore sealing performance.
During long-term operation, original sealing components can lose elasticity, harden, shrink, crack, or otherwise become less effective. When this happens, diesel fuel can escape from sealing points, while air may enter the fuel system under certain conditions.
Installing suitable replacement seals and gaskets can help:
- Reduce external fuel leakage
- Restore sealing around service points
- Improve fuel-system integrity
- Reduce repeated fuel-system priming problems caused by air entry
- Support more reliable pump operation when seal deterioration is the underlying issue
The kit does not increase injection pressure or independently restore worn internal pumping components. If the hydraulic head, rotor, governor, or pumping mechanism has significant wear, those problems require separate diagnosis.
6. Which Pump Problems Can Be Related to Worn Seals?
A DPA pump may require seal replacement when visible leakage develops around its sealing points.
Common indications include:
- Diesel wetness around the pump
- Fuel leakage near the pump shaft
- Seepage around pump covers
- Leakage around flanges
- Persistent diesel odor
- Repeated fuel-system bleeding
- Difficulty maintaining fuel-system prime
These symptoms can indicate deterioration of sealing components, although they do not prove that seals are the only cause.
For example, hard starting or poor engine performance may also result from:
- Injector problems
- Restricted fuel supply
- Incorrect injection timing
- Internal injection-pump wear
- Other fuel-system faults
A proper inspection should therefore identify the source of the problem before selecting the repair scope.
7. What Should Be Inspected Before Replacing the Seals?
New sealing components work correctly only when their mating surfaces remain serviceable.
Before assembly, inspect the pump shaft and sealing areas for:
- Scoring
- Corrosion
- Excessive wear
- Surface damage
- Housing damage
- Distorted mating surfaces
- Contamination
Particular attention should be given to the shaft sealing surface. A worn or damaged shaft can cause a replacement seal to leak again even when the new seal itself is in good condition.
The pump housing, covers, and gasket surfaces should also be cleaned and inspected before assembly.
If the repair expands beyond basic seal replacement, internal components such as the hydraulic head, rotor, pumping mechanism, governor, and advance system may need further inspection. Professional injection-pump testing and calibration may be required after a more extensive rebuild.
8. How Should You Verify a 7135-110 Kit Before Ordering?
The most reliable approach is to match the repair kit to the actual injection pump identification.
Before Ordering 7135-110, Confirm:
- Repair kit number: 7135-110 / 7135110
- Pump family: CAV DPA
- Complete pump identification number
- Cylinder configuration
- Drive arrangement
- Shaft type
- Engine model
- Equipment or tractor model
- Existing seal configuration
- Pump identification-plate photograph
A clear photograph of the pump identification plate can be especially useful when the complete number is difficult to read.
If the pump uses a keyed drive shaft, confirm whether the application requires the additional 5393-252R seals before ordering.
For distributors and wholesale buyers, providing the pump number together with the equipment information can make compatibility verification faster and reduce incorrect-part orders.
9. When Is 7135-110 Enough for a DPA Pump Repair?
The 7135-110 Repair Kit is most appropriate when the pump remains mechanically serviceable and the main repair requirement involves gaskets and seals.
Typical situations include:
- Replacing aged seals during scheduled pump service
- Repairing external leakage caused by deteriorated sealing components
- Renewing sealing components after pump disassembly
- Servicing an older DPA pump before returning it to operation
A more extensive rebuild may be required if inspection identifies significant wear in the hydraulic head, rotor, pumping mechanism, governor, advance mechanism, or other precision components.
Therefore, choosing 7135-110 should depend on the condition and repair scope of the actual pump, rather than treating the kit as a universal solution for every DPA pump problem.

11. Frequently Asked Questions About 7135-110
Q1: Can I identify the correct 7135-110 kit from the engine model alone?
It is better to use the complete injection pump number. Engine and tractor information can narrow the application, but different pump configurations may have been installed on similar equipment.
Q2: Does 7135-110 apply to both 3-bolt and keyed-shaft pumps?
The kit is commonly associated with DPA pumps using a 3-bolt drive, while certain keyed-shaft configurations may require additional 5393-252R seals. The actual shaft arrangement should therefore be verified before purchase.
Q3: Are all 7135-110 aftermarket kits packaged with identical parts?
Not necessarily. Aftermarket suppliers may offer different kit configurations. The current supplier parts list should be checked if the exact number or type of seals is important to the repair.
Q4: Can I use 7135-110 if the pump has both a fuel leak and low engine power?
The kit may address the leakage if deteriorated seals are responsible, but low power requires separate diagnosis. Internal pump wear, injectors, fuel restrictions, or injection timing can produce performance problems that a seal kit cannot correct.
Q5: Why is the pump identification plate important?
The identification plate can provide the pump number and configuration information needed to distinguish between similar DPA pumps. This is generally more reliable than matching only the tractor or machine model.
Q6: Should I replace the seals whenever a DPA pump is disassembled?
When sealing components have been removed during pump service, replacing aged sealing components can help avoid reusing deteriorated parts. The appropriate repair scope still depends on the pump's condition and the service procedure being followed.
Q7: Can a 7135-110 kit restore a completely worn injection pump?
No. The kit is primarily intended for gasket and seal service. A pump with substantial wear in its hydraulic head, rotor, pumping components, governor, or advance mechanism may require additional parts and professional rebuilding.
