Just about to clock 90000 miles in my 300 tdi discovery and though it would be a good time to renew the timing belt. According to the service records I have, the belt was changed at about 60000 miles. Any advice on doing the job - the engine overhaul manual refers to some landrover tools for doing the job. Are these a requirement or can the job be done (without too much hassle) without them. Thanks in advance. Davy M.
Manual or auto, bit eaiser in manual as you can lock the engine... if it is an auto you can make the lock tool that bolts to the crank pulley and yo u can make this into a puller as well.
You also need the lock pin for the pump, spin one up on a lathe something like 9.75mm

Davy,
Search for instructions on the web. I found a few that made it easier and have some advice about commonly available substitutes for the tools.
Thanks Max. I forgot to mention it is an automatic. How long should the pump lock pin be?

OK went and had a look there are 3 tools you will need
1 - to hold the crank pulley and pull it off. An upside down top hat, the hole through the middle needs to take your socket, on the lip 4 holes to line up with the crank pulley, and a handle on the other end to hold it.2 - lock for the engine. 14mm x 1.5 bolt x 20mm long. through this is M10 x 42mm ( ish ) bolt. This goes throught the bellhousing ( the inspection plate at the bottom that you do the torque conveter bolts up through )
3 - pump lock pin. The bussines end of mine is 9.34mm by 45 mm long then a handle bit 40mm long.Make sence ?? i try and put some pics up on the www tomorrow ..

a 9mm drill bit does the trick
I built an extractor with a base plate and some screws similar to the Land Rover 'Special tool' only to find it came off with no effort and no need for the tool.
To lock the engine, I used some dinghy mainsheet rope wrapped around the pulley ( In the opposite direction ) as much as you can and then tied it to the chassis. Worked a treat.
Before I took the belt off, I marked each pulley (3 Altogether)and the belt with two marks in yellow paint. After I took the old belt off, I transferred the marks to the new belt and checked by counting the number of teeth between the markings. You can re-check them again on installation but this made the whole job easier as you could see what you had to do.

Many thanks again. Your photos make a good job of making clear what is required. I've just got to make them up and do the job now!
Thanks again Davy M.
