I have a disco 300TDi, with approx 65Kon the clock, i beleive there is a modification to the timing belt case. How does one know if this mod has been done. Is there a new part No. on the timing case to cross check against. Is there any modification to the timing belt tensioners as well. Does anyone have a reference I can look up on the interweb thingy to assist in this.
Thanks
Tony
There should be a square of yellow paint on the timing case but it's not always there. If you look at the rear of the injector pump there is a right angled bracket from there to the block and if the mod has been carried out this will have been changed to one with self aligning sleeves in two of the bolt holes.

At 65,000, the timing belt should be due for a change. It should be fairly obvious to the garage when this is being done as to whether the necessary mods have been done.
The following extract from
What is the problem ? The timing belt on 300Tdi engines fitted to Defender and Discovery and Range Rover, suffer from premature wear due to miss alignment of some of the guiding pulleys. If serious this should manifest itself before the 60000km change interval.
What is the solution ? Land Rover issued a technical bulletin No. 0008, on 25 March 98. This bulletin details the fitment of one of two possible rectification kits, depending on model numbers. Where the kits have been installed workshops are instructed to paint a 2cm square yellow block on the upper left side of the timing cover.
