brakes

I have a 1997 Lunar 462 for the past 10 years ive had it serviced at a couple of dealers, but because of problems the last couple of times ive decided to service it myself. So first off I need to know the torque figure for the 1 shot drum nuts. Can someone help. Allan

Allan,

A typical value for the AL-KO Euro and Delta single shot axle nut is 290 NM and this creates two problems:

The first is the required torque, which is outside the usual range of 1/2" drive torque wrenches (max of 200 NM) and so you'd need to find a 3/4" drive wrench (more expensive - double the price), and a 3/4" drive socket

The second is that the torque value needs to be accurately set - so you should use a calibrated torque wrench - which will be accurate to better than 5%

A 3/4" Sealey torque wrench calibrated to 4% will cost around

Allan,

I have a Lunar LX2000 462 and used to have it serviced at the main dealers. After getting fed up with grease dropping off the van, onto my new block paved drive. I decided to get a caravan mobile fitter. What a difference! Van was serviced on my drive without a spot of grease being spilt.

The van towed better, no binding brakes, the water pump ran quieter and the heating thermostat seemed to turn on/off better. If you have the choice get yourself a mobile caravanman as they do like to give good service for obvious reasons.

Best wishes,

Pop

Thanks for getting back to me with the torque figure I can get my hands on a torque wrench so thats not a problem and as to getting a mobile fitter I tried that but they still wanted over

Allan,

When you say you can get your hands on a torque wrench, 3/4" drive (calibrated) torque wrenches are not exactly common - unless you know someone in an engineering company that is.

290 NM is roughly the same torque as many 2 litre diesel engines produce at the flywheel - and is way outside the normal range of hobby torque wrenches.

I have a three quarter drive torque wrench it's a Churchill item as supplied and used in many franchised dealers. It along with my other torque wrenches used to be regularly checked by the motor sport team I worked for (at their expense) very rarely did they need any attention. The key to any torque wrenches accuracy is to always take the tension off when not in use. Just tension them as you use them and release it immediately you have finished.
