Posted: Mon Jan 31, 2011 21:22 Post subject: Inflating Lorry Tyres . ...wtf ? |
|
|
Wife has told me the tyres are looking like they need air in them on her 7.5Te Iveco Horsebox
Off I popped with our Halford type inflator to confounded with wheel trims like :
We have only had the lorry a few months so never considered, need to pump them up.
Tell me : How the hell do we pump them up ? Surely I don't need to take the Wheel trims off do I ?
Madness ?
Admitting my toy inflator wouldn't get a look in, I drove it down to the nearest Garage.
Nope - poking the wand through the Gap I still had no chance.
How / Where will I get them inflated?
(and thanks to another thread I assume 90 PSI ?) _________________ If you google google it breaks the whole internet |

Yep thats trims off and a trip to the nearst truck tyre dealer to get 90psi in .
Or stop a passing tyre truck fitter , there will be some mobile freelance boys near you I'm sure .
Dont go up the local garege as the tyre will beat the 50p air thing my mate did that and 2 quid later he came away with 60 psi not 105 .
Oh also have a look at the air tanks sometimes there is a fitting put on so you can couple up a tyre line blow your own tyres up off the trucks air system - bit slow though . |

You need a security torx to undo the trims - then as posted i recon 85 psi on 75.tonner tyres
these need to be checked every 6 weeks as per the VOSA servicing guidlines
surley she has this info ?
its classed as a HGV for servicing purposes lol
all ours do 450-750 miles every six weeks and still have to be inspected / serviced
cheers

I dont think you need an operators licence for a horse box as its classed as a motorhome _________________ |

Yeah, someone on the Horse and Hound web forum (ohhh the shame !!!) said bin th bin lids as they hid the wheel nuts for inspection etc.
Does seem a little daft, but I set to them with a torx set and went to my friendly ATS commercial depot over the Road.
Turns out the pressures all round were not too bad but the Wheel Nuts
Some were pretty loose !
I need to find a Torx Screw driver I can keep in the cab to do it easily - 9/64's ? sound about right ?
I can only see a full set type thing. _________________ If you google google it breaks the whole internet |

Should be T20 or T25 type thing ? I would get the ordinary torx replaced with stainless steel security ones and get a driver for them too . |

The guy over on the HorseHound thread is adamant I sling them all together - potentially dangerous things in the way you over look the Maintenance of the Wheel nuts _________________ If you google google it breaks the whole internet |

You should bin them as said - when we have them fitted they have to be removed every six weeks for the fitter to check the wheel nut torque
if they are not there you could use some bright wheel nut pointers - visual aids for wheel nuts coming loose

I must be imagining things but I am sure I read here that someone said you can often use the Air Brake System / Compressor to Inflate tyres.
is that right ? Obviously a mod, but it does sound sensible.
As for the Torx Screwdrivers - no such luck _________________ If you google google it breaks the whole internet |

on the heavy plant we had the bayonnet type fiitings on the ends of our air tanks to top up the tyres as and when needed, yeah its a mod but any pirtek or hydraulics outlet will have the fittings and its not a big job to fit, PTFE tape, fittings and adjustable spanner, really handy if you get a slow puncture on the way and need to top up til you get back to civilisation. _________________ Dead on my feet but sitting on my *beep*!!! |

Seems a good idea, not sure if the tank / compressor on the 7.5Te Iveco will be man enough for it though.... _________________ If you google google it breaks the whole internet |

Most air brake systems run at 130 psi or 10 bar - tyre inflation isn't recommended as it can over heat the compressor

do remember though that as long as there is oil flowing over the gear drives on the compressor it should have a cooling effect and on top of that just a thought, air brake, the compressor runs all of the time anyway to ensure sufficient service brake pressure, not sure how diverting that what would be surplus air that would only be dumped by the relief valve would have any bearing on the heat build-up of said compressor? _________________ Dead on my feet but sitting on my *beep*!!! |
