CAV Lucas DPA Pump Top Cover Repair Kit 7180-872A | 7123-888A With Throttle & Shut off Shaft

Why Replace your Top Cover assembly?
Over time, the CAV/Lucas DPA top (governor) cover can become worn, damaged, or compromised due to normal use or improper disassembly. This often leads to fuel leaks or a cover that can no longer be reliably reused.

This kit includes a new gasket and sealing components to ensure a proper installation. The original mounting gasket frequently deteriorates with age and may not survive removal, while the O-rings on the throttle and shut-off shafts can lose their sealing ability over time.

In addition, the throttle and shut-off shafts themselves are subject to wear or damage. In some cases, replacing seals alone is not sufficient to restore proper function, which is why this kit includes new shafts as well.

Together, these components provide a complete solution for restoring proper sealing and helping eliminate leaks from the top cover area.

"Jason will be your pump man if you let him"

From a Customer who Found Us on Ebay: "Just a note to let you know that the injector pump that you re-built for me works like brand new. If there is anyone here that needs one re-built I will tell them you are THE BEST IN THE COUNTRY". Thank You so much Ken - AZ

I rebuild and set these pumps for a living, and have been doing so for 34 years, If you would like to send me your pump to be rebuilt, contact me. Most of the pumps that use this top cover will run about 450.00 to be rebuilt. We can also check and clean your injectors for free, so send them along as well. After checking your injectors, we can give a quote if any fail testing.

Here are some of things that can effect the price:

  • Pump is locked up and/or the main drive shaft is broke.
  • Engine will not start when warm, after sitting from 1-60 minutes. But does start when cool. This may indicates a bad head and rotor.
  • Cam ring in pump is worn, requires inspection during tear down.
  • Pump has excessive rust and corrosion.
  • Housing is damage or unusable.

Here is how it works:

  • Contact me with your pumps Models numbers.
  • I will try to give you a closer estimate based on the problems you describe.
  • Pump must not have been taken apart.
  • Pump must be drained of all fuel as shipping service may return or destroy packages that leak fuel.
  • You ship your pump to me pre-paid. (Packaged well, I can not be responsible for items damaged in shipment)
  • We check the pump and contact you with a full estimate, return shipping cost and time you should expect your pump back. (Normal times are a week to 10 days).
  • If you choose not to have your pump rebuilt after the estimate, all you pay is freight back to you.

Why would you want to do this?

  • Pump will be cleaned, inspected, rebuilt, tested and will look and run great.
  • All fully rebuilt units are invoiced and include a 6 months warranty.
  • We will provide tips for reinstalling as well as some of the parts you may need to do so.
  • We have access to parts, specifications and test equipment to make sure your pump is right.

Remember the call is free, the service is great and my knowledge base covers over 30 years. DC pumps are higher

Payment for rebuilt pumps must be paypal or Credit Card before we can ship the pump back to you, Thanks.

Please Note: Your fuel injection pump is a very technical device. Not only does it control your engine it also protects it as well. Repairing your pump yourself may be a great way to save money, but proper care must be used as serious pump and/or engine damage can occur. Any person(s) attempting to repair, or otherwise maintain, a fuel injection pump is assuming the full extent of the aforementioned risks.
