Over the weekend, I had the opportunity to re-work the power steering pump
on my 90 XJ6. I had noticed a leak in the system for some time … but it
wasn’t killer so I used some seal enhancer to hopefully rectify the problem.
Well … it was to no good end as the leak increased significantly this past
Saturday as the wife was driving.
Upon her return home, she informed me that the “car was smoking”. A closer
inspection revealed Dexron burning off the exhaust manifold and cat
converters. After a quick de-greasing and another test drive, the problem
was manifested itself as an apparent power steering pump seal leak … lots
of red blood directly below and around the front of the engine.
Let’s start by stating that Haynes is exceedingly simplistic with regards to
this repair work. Lots more to the problem than the simple paragraph Haynes
devotes to the subject. After jacking the front of the car up on stands …
and removing the exhaust manifold heat shield (and EGR valve) to allow
access, I was able to remove the inlet hose and high pressure hose from the
The pump itself is secured to the engine jack shaft via three 13mm head
bolts that are NOT located for ease of manipulation. These bolts are a
b&t*h to access. Finally, I was able to remove the bolts and pull the power
steering pump out via the engine bay. With the pump in hand, the fun just
begins to start.
The pump shaft is attached to the engine via a standard spider type coupling
… but there’s a problem. The pump shaft coupling hub is pressed onto the
pump shaft … not easy to remove. I was able to remove the coupling hub by
some creative machinist work with the excellent help of my local machine
shop. With the coupling hub off, I was able to remove and replace the shaft
The good news … the power steering pump is a conventional GM Saginaw pump
… the seals and rebuild kits are very plentiful and inexpensive. Not
wanting to break into the pump (as there was nothing wrong with the pump), I
decide a seal replacement was all that seemed necessary. The cost of the
seal was $5.00 US.
After replacing the seal, the machine shop helped to re-press the coupling
hub back onto the power steering pump shaft. This part is not as simple as
it seems as you need to place the hub back to the exact location you found
it. Thankfully, I pre-measured the distance before removing the hub. The
machine shop charged me $6.00 US for the press work.
Its accurate to say the re-installation work was a bit simpler than the
removal as I was already familiar with the work. It was about 2 hours for
removal and 1 hours for re-installation. The total cost … $14 US with the
new Dexron III.
The really bad news … I contacted my local Jaguar dealer and asked if they
had the tool for removing the pump side coupler hub. The answer was …
maybe, but it would take two weeks before they could work me into their
schedule. Two weeks to attempt a 15 minute job … these guys are truly
customer driven. Can you imagine the price the dealership would have
charged for this repair work? Another example of excellent Jaguar service
… needless to say, I declined their service and did the work myself.
Every weekend is a new adventure …
