Car Forum / Land Rover Cars / November 2005Timing Belt tension on a 200Tdi
Hi folks, The manual says "tension with a lever-type torque wrench to 20Nm" Is that right ? It sounds like bugger all. Steve >Hi folks, >The manual says "tension with a lever-type torque wrench to 20Nm" > >Is that right ? It sounds like bugger all. Its not too far off what my workshop manual says for the 2.5 diesel (29 to 23 Nm) - so its feasably correct. If you are replacing the timing belt you need to double tension it, i.e. tension correctly once, rotate engine by hand for a couple of revs, and repeat tensioning. I think there is a good description on difflock website (for 300tdi, but very similar). Pieter > Hi folks, > The manual says "tension with a lever-type torque wrench to 20Nm" > > Is that right ?

Besides which and despite popular folklaw, it is not an elastic band.

The amount of stretch is minimal indeed.  SignatureAustin Shackles. www.ddol-las.net my opinions are just that "Chuck didn't reply, so George swung round in his saddle. He could just see Chuck's face, a white oval turned toward the sky. 'Look,' whispered Chuck, and George lifted his eyes to heaven. (There is always a last time for everything.) Overhead, without any fuss, the stars were going out" Arthur C.

The amount of stretch is minimal indeed. Which is just as well, as setting the timing with a stretchy belt could represent something of a challenge.......... ;-) Richard Signaturewww.beamends-lrspares.co.uk sales@beamends-lrspares.co.uk Running a business in a Microsoft free environment - it can be done Powered by Risc-OS - you won't get a virus from us!!
