TD5 Front Pulley

LeroyC · Dec 28, 2022

Hi all,
Fitting a new front pulley at the moment, have a new bolt.
The question is do I put oil on the thread & under the head?
The workshop manual just says to fit the bolt & tension it, nothing else.
Any help would be appreciated - Thanks - Leigh

Assuming the engine is a TD5 and that you mean the crank pulley the bolt is fitted dry but must be torqued correctly

I'd like to see the look of a 2006 Range Rover Diesel Td5 though

The Range Rover man in Melbourne said to put engine oil on the bolt & we tensioned it to 460N/m, we did it & it went OK
As a reference we set the small tension wrench to 100N/m & tightened to that to start off, and then marked the bolt & pulley & then went with the 1000N/m tension wrench to 460N/m the bolt moved an extra 2 flats (120°)
We hope this gives us a base angle torque for next time for a bush emergency. (In the outback it is not easy to find an 1'' - 3/4" tension wrench)
P/S Engine had TD5 written on it, 5cyl, Wastegated turbo, Unit injector type, EGR, auto trans & alum. radiator & intercooler. Australian ADR plate.
Thanks - Leigh

What ever your tourque wrench setting was it became redundant the moment you put oil on the thread, you will get a false reading and in any even it will work itself loose. Not a good move mate. Plenty of video's on you tube about tourque settings and oil on threads.

The Melbourne dealer where the vehicle owner bought the new pulley & bolt is a mate of his, so if there is any
trouble we will put it back on him, I did not want to use oil at all, we showed him the page out of the shop manual, it was his recommendation. I was waiting to hear back from you guys, but the owner wanted the vehicle urgently.
Thanks for your help.
