G'day,

It seems I might need to change my logon to DieselPete (if it's not taken), as I've bought a Dec. 2002 4.2L turbo diesel auto Landcruiser at only 48 K Km. And it came with what appear to the untrained eye to be "poly air bags' in the rear suspension. A red colour.

When I hitched up my 25Ft van at about 2.3T for the trip to Mudgee for the long weekend, she was a bit low, so I put 35psi in the air bags and that worked a treat.

But what I don't know is, what are the limits of the air bags.? What is a safe maximum pressure? There were no brochures or instructions with the vehicle.

Your experiences would be greatly appreciated.

So, why is "LPGPete" maybe no longer appropriate? Well I had a 99 Ti Patrol on dual fuel and the cat converter in the emission system blocked for the 2nd time in 6 months and the Cruiser just happened to be next door to Nissan at the Toyo place - and they don't come up second hand very often - so I jumped at the opportunity - and it tows like a dream as though I have a few more gears available.

The Patrol was great - the Cruiser doesn't have climate control - Grrrrr!! But as we're off to The Centre next week for 5 weeks, I couldn't take the chance of getting stuck somewhere!! And it's all thanks to Mr. Costello anyway for us self funded retirees. He paid for the changeover by removing the RBLs!! Nice man.

All the best and I look forward to your replies.

Pete

I run the firestone's and they have a max pressure of 35psi, which is what I always run when loaded up on the highway. They are brilliant.

Hi Pete

My 100 series also runs the Poly air bags and when fully loaded with van and car I pump them up to 180 kpa. The best way to check is first measure the hight of the ball. Put 150kpa in them, hook up the van and deflate if needed to drop th ball down to normal drive height.

When you get home deflate to around 50 kpa to stop the bags moving in the springs and pulling the pipes out.

Regards Derek.

Have heard some stories about air bags failing after a few years, something to do with the area around the air intake ?? Maybe a furphy, maybe just one brand. I'm seeking clarification at the moment.

I have had Poly air springs in my VL Commodore wagon since about 1992. I needed them to support the weight of all the junk you need to take camping with kids. They worked really well. I forgot about them since about 2002 and now found that they have separated at the inflation holes. I attribute this entirely to lack of inflation - all my fault. So keep them inflated at about 10 psi minimum and you should have no trouble.

Thanks everyone for your replies.

Very helpful info and I'll study the Polyair web site when I get a moment.

And ... RBL = Reasonable Benefit Limits ... as in superannuation ... and as they've been removed by Mr. C, we can now have access to asll of our hard earned.

Thanks again.

Pete

I have Patrol 4.2 Td an poly,s red fitted 30psi max and nothing less than 5 psi when not in use ((NO WEIGHT)) so I drop mine to 10 lowest if not towing.

Happy Poly Towing.

Hi Pete

When you inflate them they can not go more than half way through the gap in the coil, I hope that made sense.

And never have less than 5psi in them.

Have fun

Pete,
I recently purchased a set for my 100 series and was told at the time never to inflate them over 25psi and always have a minimum of 5psi in them, to stop them from pinching. I presently have them sitting on 10psi with a modicum of off-road accessories fitted but expect they will need more when loaded up for a touring trip, which is essentially what we purchased them for.
