Centre Lock Torque Wrench

[Lancerlot]

Those with Centre Lock wheels will be aware you need to tighten the Centre Lock bolts to a torque of 600 nm and torque wrenches capable of this kind of grunt are few, far between - and expensive!

However, Auto 4 in Solihull currently have a special offer on Norbar Torque Wrenches this week and can supply a 300 - 1,000 nm unit for £280. The unit comes with a calibration certificate (+/- 4%), a handy folding storage case and free shipping.

If you fancy one you can contact Paris Dineen 01235 776636. The offer is open until 5pm this Friday 17th September.


BTW - It's ¾" drive, so it will fit directly into your Porsche supplied socket. You also get a 1" adapter as part of the offer and this would allow for some really serious torqueing!

Regards,

Clive

Ordered 12.30pm yesterday - arrived in good order 11.30 today.

Certainly can't complain at the shipping lead time! []

Thanks Clive, very interesting. I seem to recall from previous posts that you used a torque multiplier on your centre lock wheels. If so, have you decided that it did not perform very well and that a full on torque wrench is a better option? I ask because I am considering purchasing a torque multiplier, partly because of its more compact size and could be carried in the front boot.

I use a torque multiplier (snap on) and it works fine with a standard 1/2" torque wrench. As all garages have one of those I just carry the multiplier and the socket of course.

Hi Terry,

The multiplier is fine. I have used mine for more than 10 years without a problem.

The advantage of the wrench is it works directly on the bolt without an intervening tool and is therefore a little more convenient with a reduced chance of slipping when forces are applied.

However, the wrench is a fairly sturdy piece of kit and probably best stored in the garage rather than carried around in the car.

Just invested in a Norbar 5R-N 3/4 drive wrench to get my winters off my Panamera and my summers on. £396 from Somerset Commercials, ordered yesterday, here today. Saves me the hassle of a visit to the OPC and allows me a bit car centric activity on a rainy day. Also tooled up with a big breaker bar, Castrol moly grease and a mandrel. All I need to do now is persuade the wife to hold the footbrake down.
I've also heard that Porsche and not keen on multipliers because of their reaction arms acting on their wheel spokes and why I have stuck with long lever and wife approach.

I'm not sure exactly what Porsche is referring to here. The photo shows the Sealey multiplier in action and it doesn't go anywhere near the wheel spokes. (Photo perspective is deceiving) It simply increases the available torque to the wheel bolt. However, using a suitable torque wrench to tighten directly does reduce the number of interfaces and simplifies the operation.

Clive,

Of course you are right and the Sealey multiplier would seem to be an excellent solution when coupled with the tried and tested Lancerlot method.

I wouldn’t be as confident with the multipliers that get their reaction from engagement with the wheel spokes, but that’s a personal opinion.

Randall

PS, I was half expecting a comment that centre locks have no business on a Panamera !

I have a Sealey torque multiplier for sale if anyone is interested. I no longer
have a car with centre locks so have no further use for it. It has only been used 5 or 6 times so is as new. £125. Message me for any more info

I have seen some multipliers that use the wheel (spokes generally) itself as the resistance so perhaps Porsche are referring to those styles of multiplier.
