Subject: Dead tach on '87 RR

    Tom,

    You may be on to something with the alternator.  When my drive belts (87
    RR) came loose the other day, I noticed that the tach went dead while
    they were squealing and came back instantly when the belts got traction.
    I don't know what the connection is but it appears there is one.  Maybe
    the tach reads the AC frequency from the alternator and translates it
    into RPM. Did you have any "left over" wires?

    As to the plugs: you should always be a little paranoid on something as
    expensive to repair as a Rover but I've been using Bosch platinum plugs
    (don't have the number avaialble) for years now with no problems.  I
    suspect the warning has to do with the heat range and the risk of
    detonation, which is particularly hard on an aluminum engine.

_________________________________________________________________

The tachometer on my 87 RR has decided to quit.  I have
about 90K miles on the vehicle.

I first noticed the problem no more than one day after replacing the
alternator. (May have been same day and I just failed to notice.) Does
anyone think there's a correlation?  Or, is there something else I ought to
check out?  (I had NOT been fiddling around with the electricals or behind
the instrument binnacle.)

Also, a second (and unrelated) question:  I had a local garage change the
spark plugs on the 3.5 about 5K miles ago. Reading through the RR shop
manual it states very ominously that only the correct type of plugs should
be used or MAJOR engine problems could develop.  The plugs in there are
AC's (R44XLS).  Should I replace with Champions as the shop manual
specifies or am I just being *paranoid* here?

Yo Dave:
the "book" specifies 10W40 or 20W50 for ambients of 86 to 122F, lyou know,
normal Wisconsin  summers.  I'd personally choose the 10W40.  Easier starting
for those brief summer forays into minus 3 degrees F.

Someone told me the tach signal for the Defenders comes off the alternator.  

same for rangies?? Might explain the coincedence.

Re teh plugs, I'll bet that when they said severe engine damage, they really
were concerned with "reach" of the plugs, meaning how deep they project into
the cylinder. This is obviously to prevent the piston from meeting teh spark
plug, and and on engines with small or wedge shaped quench areas it is of
supreme concern.  That your truck runs and doesn't emit very bad sounds right
now means plug reach is not excessive.   Proper heat range is important to be
sure, too, and if the heat range is not correct, I would want them replaced.
 Heat range can affect mileage, and probably startability, and plug life and
fouling tendencies.  I don't know the specifics of the RR engine though, so
I'd just go with what the manual reccomends.

    Barnett,

    FYI: Gas weighs about 6 lbs per gallon.  That's why it floats.
    Good luck with your rack.  Just don't forget the potential effects of
    being rear-ended on five or ten gallons of gas in a very vulnerable
    place.  There's a lot of heat energy there.

I checked the D90/D110 shop manual and the electrical schematics show 
the tach having three connections: 1) to ground, 2) to power through the 
fuse box, and 3) to the "alternator stator windings." Assuming the tach 
setup on the D90/D110 is the same as on an RR, I'd start looking at the 
alternator connections for the problem before trying to pull out the 
tach.  Good Luck.

You might want to check the four "nylock" nuts on the back of the emergency
brake housing where the driveshaft bolts on.  After a west coast list off
road trip one of the list members mentioned that his were loose.  I went out
to check mine and found two of the nuts very loose.  I put Lock-Tite on all
of them.

The Rover 3.9L had 8.13:1 from '89 until it was increased to 9.35:1 in '93
the 4.0L in the new Disco's also has 9.35:1.

Good info about tires; pity that as in nearly all tire tests I've seen 
there was not a chance to get a side by side comparison (eg of Trac Edge 
vs XPC).

Yes there probably is a correlation; have a look at the little lead that 
plugs in to the back of the alternator about in the middle; when it is 
disconnected the tach ceases to function.

The alternator drives the tach. Make sure the tach cable is plugged into 
the right terminal on the alternator. Try cleaning the connector to make 
sure you've got good contact.

Subject: Fuel Pump Replacement

The RR got to ride on the back of the flatbed again!

I stopped briefly this morning and then the RR would not start.

My feeling is the fuel pump failed.  Good spark and coughed with a squirt of
starting fluid.

Fuel tank was replaced in January and a new fuel filter installed.  Tank has
leaked from the top ever since when filled up.  It could be a bad gasket or
it could be leaking though the pump wiring area.

Electrical power is good to the pump.

A new pump should arrive tomorrow from RN.

What other areas should be checked before pulling the fuel tank and pump?
Any suggestions and words of wisdom from those that have done this already
would help.

Thanks.

Subject: Re: RR Fuel System Problem

Jeff -- I haven't done this job, but I wonder if you could simply test 
the fuel pressure somewhere along the line? Or even yank off a fuel 
hose somewhere and see if petrol squirts out into a handy container 
(could be dangerous though). Also, can you hear the fuel pump running?

Another possibility may be that the power source to the injectors failed; 
maybe worth checking the fuel injection relay?

Good luck

Subject: Tach-alternator relations

Regarding the 'dead tach on an '87RR' thread, I have a really irritating (and
embarassing especially at night) problem on my '89RR where 'something' under
the hood squeals loudly periodically.  When that happens, the tach dips or
hesitates.

I suspect the squealing is caused by the alternator spindle bearing, though
it's really hard to tell where the noise is coming from -- I do know it's on
the driver's side of the engine bay.  It doesn't appear to be a loose belt, as
the belts are tight enough.  And it doesn't explain the tach dipping when it
happens -- unless the tach runs off the alternator.

Has this happened to anyone else?
