Preventative Maintenance NT Pajero

Preventative Maintenance

Our NT auto diesel has been a reliable vehicle with around 175k on it.
It is regularly serviced and fluids ie auto and other drive train fluids fluids changed every 50k.
Inlet manifold has been cleaned and it has a Donaldson 3 micron 99% efficiency filter and oil catch can fitted. All recalls have been completed. Fan belts have been replaced and a new set of hoses will be fitted before our next big trip. Ditto a new set of tyres. Battery was replaced in 2018. Brakes are fine. Tappets will be check at 200k. Might even fit some new fuel lines at 200k.

I'd like some input from the Pajero Club brains trust re additional items I'm likely to attend to. eg

Wheel bearings - km ( im thinking 200-250k - happy to be told otherwise)
Suction control valve (I'm thinking around 200k)
What else?

Thanks in advance

Hi, I just want to know what’s symptoms of bed suction control valve?
Is it running rough in the first start when cold weather?

Scv symptoms are surging.

I think you're pretty much on top of it.

It doesn't necessarily count as preventative maintenance, but I learned that I had two dragging brake calipers (one front, one rear) by monitoring tyre temperatures with internal tyre pressure sensors.

I wouldn't have seen it with external sensors. In comparing results with fellow travellers, the external sensors don't give useful temperature information. It took a lot of monitoring, and ruling out other potential influences such as sun, wind and road conditions, but I found the problem long before I noticed excess brake dust on one wheel (as I had with Shorty) or unevenly worn pads come pad change.

I'm hoping it might warn me of failing bearings, but I can't speak from experience.

I have a Masten system (found thanks to this forum) that is routinely available for a little over $200, including a 5th sensor for the spare. Pressures and temperatures are always displayed on the screen, and it has configurable alarms for both. For less than the cost of one tyre, I think it's cheap insurance with the bonus of diagnostic capability.

Hill.

330,000 on our NS. Original bearings and water hoses. Like your's it's serviced regularly.

Things we have replaced..Suction valve around 220,000 was surging. Swirl control valve around 120,000 was throwing codes. Belts twice, glow plugs around 225,000. Only running on 3 now as one old one snapped off.

Runnig a dream. Just dd outer western suburbs to Brisbane via New England averaged 10 5. Return via M! 9.8. No complaints for a 2 tonne vehicle.

Do you service transmission every 50k?


Are you using original fluid or aftermarket, like Penrite or Nulon fluid?

Same as you we have done the preventative maintenance and usual mods.

210k our NT had a wheel bearing and we changed the belts and ac pulley.

Looking at the glow plugs for next service. Haven’t changed water hoses as yet they still look quite good and we have flushed the radiator a few times since having the car.

Sounds similar to what I do. All fluids (diffs, transfer case, a/t, brake fluid, coolant), regular filter changes, belts and hoses (I keep the old ones as emergency spares in the seat well), and keep an eye on normal wear items (such as engine mounts, suspension bushes, ball joints, etc)

Personally, I wouldn’t bother doing SCV and wheel bearings ‘preventatively’ - I’d wait until they show signs of wear (ie noisy wheel bearings). Don’t use aftermarket wheel bearings, according to several friends who have used them, aftermarket seem to fail much. Out of interest, my NT is over 300k and still has the original wheel bearings but had to do the front upper control arm ball joints. It’s all about doing regular checks and addressing anything found.

The a/c cabin filter is another this often forgotten.

When you do the rad hoses don't forget to do all the other little coolant hoses around the place like heater core etc. They often get forgotten about but are still degrading due to age much the same as the rad hoses.
Maybe also consider the intercooler hoses as well, if nothing else a good check of them to be sure they aren't degrading. I haven't read/heard of Pajero ones failing but on makes to get a mention from time to time.
Other than that I reckon routine checks is the way to go, fixing/replacing when worn or before your next big trip if you think it's getting close.

Thanks everyone for your input. Keep them coming.

What I'm also after are items that will stop us. We always try to get away each winter for 3 months/ 15 -20k km and to date have towed our Quantum to the tip of Cape York, NT and WA , Gibb River Road etc. Were looking at completing The Savannah Way this winter.

While I do a fair bit of servicing myself I always have a pretrip check at least once a year.

Nj swb - have had a few grabby brakes in the past but never in Pajero. Good thinking

Bruce&Bobbie - Your NS has given great service. My mates NP has 350k on original bearing and fuel pump. Must admit I get nervous when travelling with him and its notheing to do with bearings.

Kimmy - Auto has a flush, filter and Penrite auto trans every 50k. We tow a 2.4T off road camper.

Crojo - Thanks for the heads up re ac pulley.

Geopaj - Agree re SCV as this shouldn't stop up. Disagree re wheel bearings mainly due to inconvenience of changing them out when travelling. Thanks for heads up re Upper control arm ball joints.

Dhula - Agree re all water hoses.

Input from Crojo point to replacing wheel bearings at 200k rather than 300k. They will eventually need replacing with some good quality Japanese bearings.

Anyone had trouble with cv boots - fatigue rather than physical damage?
Ditto Starter motor?
Diff bushes?

What about alternators? I know in my old Terracan they'd go at about 100,000km

Pajero ones seem to last 'forever' ?

I replaced the alternator on our old Pajero at 170k
A non working alternator will slow us down but not stop us. I have 4 batteries between van and car and 420 watts of solar

First thing on my list would be the HBB motor. I got caught out on this one and many are failing now. Once it fails you lose brakes in a very short time and unlike a power vacuum system cannot even have limited hard braking. It takes time to figure out how much of the MC needs attention and then source parts. MM only sell complete units for around $3500

That is actually a good idea. The HBB motor has been on my mind too.

Your explanation of how the system works once failed reminded me of a race car I used to own. It had non-power assisted disk brakes. The brakes worked fine but you had to push the pedal MUCH harder than a car with power assisted brakes. That caught out a few friends when they borrowed it for a 'fun hot lap'.
