glow plug torque settings

[mvtimmyk]

this is my first post although i read things now and then. i have a '93 LN130 which needs its plugs changed (especially as it has got cold recently!). i am no mechanic but reasonably competent diyer and was going to replace the plugs myself but was wondering if there is such a thing as a published torque setting to put them in at?
thanks for any help

all i did when i done mine last week was to just tighten them till i felt a bit of strain on the ratchet.Don't force them in to far just take your time and you will feel when they are tight enough

As stated above is good enough, but 13Nm if you want to do it by the book.

Its usually written on the box they come in as well.
