Having just gone over the pictures from when I did the front belt, oil and water pump change last weekend I realize that the year of the belt removed was 2005... so much for that full service history when I bought it!
If I don’t change the rear belt for a few months what’s the worst that can happen?

If it does break you will come to an unceremonious stop, but nothing more than that. I'm amazed the original belt lasted so long especially if you experience cold winter temperatures yµ (idµ - eAµ) ψ=mψ

Indeed... maybe I should go and buy a lottery ticket! It has 160k KMs on the clock. That probably saved it.

Just as an aside, did you replace the oil pump when you did the front belt?yµ (idµ - eAµ) ψ=mψ
The rear belt failing can cause damage to the main wiring loom across the rear of the engine and surrounding pipes, dont leave it to long..

I did. I had no shortage of expletives for that moment when I realized that I had to remove the alternator and bracket!
Thanks Flack. I’ll do it in Q1 next year. I actually lost my job this week because my project at work has been cancelled so I might have some time on my hands in February. Plus having worked on the car each of the last 3 Saturdays to get it through the Swiss MOT this month I fancied a break.

Hi there
I've got some troubles to fit the special tool DA1120 - Britpart - to lock the crankshaft (manual transmission). First it seems to be a different diameter (tool about 35mm, hole about 32mm) and secondly the starter screw has bigger bolts than the nut of the tool. Am I fitting the right tool to lock the flywheel with this tool?

Thank's a lot in advance and Happy new Year!

Certainly the cheap eBay kits require a little filling down to fit. Not as much as your experiencing, but I guess not many use britpart kits.
The bolt isn’t meant to fit that thread.

Emery cloth, remove the plating is normally sufficient for it to fit.

35mm is the correct diameter for the tool, it may be you have a build up of rust is the block casting preventing it from seating. That said, I have on occasion thought there was more than just rust causing interference with the tool fit. (casting variation?)
So either you skim a little of the block, the tool itself, or both! As Pete K say's the transmission bolt will not fit the tool, so you will need an 8mm bolt to lock it in place. yµ (idµ - eAµ) ψ=mψ

Thank's a lot for all your fast replies. Glad to hear that it's the correct tool. I'll skim the tool until it fits.
I had to use a grinder on the tool I got in a kit from Island 4x4 a couple of weeks ago, was confused at first but when I figured the tool was too bit it wasn't too much of an issue to sort out.
Kit was only £30 and the pin didn't break when torqueing the hell out of the crank bolt so no big deal 2012 Discovery 4 HSE Sumatra Black

Yes that extreme torque puts high stress through the crankshaft and through the flywheel, why dident they just put a key in that shaft/pulley instead of base it on friction to hold it.
I had to use a 2 meter long braker bar to loosen the bolt 😳

@ Kviasen
The official JLR tool for holding the pully in position is a different one and positioned at the pully...
So no big torque on the crankshaft then when mount or dismount the bolt...Best regards
