Replacement CAV / Lucas / Delphi 5393-252R Drive Seals on DPA Diesel Injection Pump

Note: These DPA Pump Drive Seals replace Delphi Part Number 5393-252.  There are usually two per application, so we sell them as a pair.  These are aftermarket seals, but we source them from a reputable vendors (not China).  We stand by their quality, and as such, frequently use them for our in-house pump rebuilds.  Each pair of seals ships to you in brand new condition, never before used, and in a sealed packaging.  Thanks.

MPN: ads-5393-252

Fitment Guide:

  • Unfortunately, there is not a comprehensive list of pumps that use these drive seals.  There are also 1000s of pumps that use them, so it isn’t feasible for us to create one.
  • You can–and we actually prefer you to–send us your complete pump number ,and let us make sure they are right for you.
  • Other than having us check, we can only offer a few general rules to help you determine compatibility.
  • For example, almost all injector pumps that have model numbers that start with U304 use these seals
  • Also, only pumps with tapered shafts use these seals.
  • And these drive seals also do NOT just fit any DPA pump that have two drive seals
  • We also know that they do not fit pump number 3342F260 or MF383 tractors (we’ve gotten this a number of times).
  • But they do fit pump model number 3233F360.
  • I’m sure this is all confusing, so essentially if you are not absolutely sure these are the seals for you, CONTACT US!

We have some tips for replacing your old seals:

  • Remember the direction your old seals were installed in. Sometimes they are both lip in, sometimes they are not.
  • Some will have a clip between the 2 seals.  If yours have said clip, make sure to put it back when you put the new ones on!
  • Also note that drive shafts have a couple indentations that are sharp and make it hard to get the seals in without cutting them.  In the field, we sometimes use the corner of a plastic bag to cover the sharp edges just enough to get the seals past.
