Thread: Tools for 300tdi timing belt change

Ummmmmm what do you mean when you say SST's.

Ive dont it and the only special tools that I needed was a 9.5mm (from memory) drill bit to keep the inj pump alligned and one I made up to get the fan off but it will come off if it isnt stuck too bad and keep in mind is left hand thread.

The only other tools you need is a 3.8" drive needle torque guage to accuratly measure 20Nm for the tensioner.

The rest is just normal spanners and sockets etc.

Do some searches, there are some good information available on this site and others.

Check this out DIFFLOCK - 300tdi Timing Belt Change It is really good info.

The main trick is to take your time

don't know about workshop cost - expect it would be over $250 + parts...

easy enough to do yourself if you have the time and tools... you'll need to have or have access ot a 3/4"' drive 27mm socket for the crankshaft pulley nut

you'll also need to fabricate

(1) a 4 leg holder to stop rotation of the crankshaft pulley and

(2) a 4 leg puller for the crankshaft pulley, and

(3) fabricate/adapt a timing pin for the flywheel and (drill bit floating in a plug), and

(4) a timing pin for the fuel distributor pump drive (sawn off 3/8" bolt)

(all really fairly easy to do if you are used to making things out of steel with a drill press & welder)

google difflock as they had a really good instruction article on all of the above and think about buying incs rave disc

if you are all ok with the above it's then all fairly straightforward after that - just put all the new stuff not forgetting new idler pulley bearings, water pump & "p" gasket

if I was closer I'd lend you my stuff and help out - regard - Laurie

can photograph my tools & email the pics to you if you like

I've seen a real easy way of changing the belt where you don't need special tools... Problem is that you need to register on another site to get the details. Mind you, the synopsis is this:

• Access cam belt.
• Slacken off tensioner.
• Using a sharp knife, cut the belt in half along the LENGTH of the belt.
• Use the knife & remove half of the belt.

[You should now be left with half a belt holding the timing in place]

• Slide new belt on.
• Carefully cut the remainder of the old belt and remove.
• Slide new belt into final position.
• Tighten up tensioner.
• Reassemble.

It's really simple when you think about it...

BUT....

this is rather questionable isn't it...

what am I missing... how do you access & replace the cam belt on a 300tdi without removing the harmonic balancer and front cover????

I think you are only misleading the person raising the question

Thanks for all the info including the link. My last experience with a timing belt/chain was 39 years ago on a Hillman Gazelle. Got it back together and found the internal crankshaft oil thrower under a rag on the ground. Now older and maybe getting wiser!

Ummmm, yeah you need to remove the harmonic balancer but that wont desturb the crank pulley.

The crank pulley is behind the timing cover so the theory is sound but I wouldnt do it, it is easy enough to do properly.

The only problem I can see being encountered is that if the belt is old and has a small amount of stretch it may still put it all out of whack and you would have to start from the start anyway.

I wouldnt want to be trying to cut the belt lengthways with a stanly knife, I recon it would be more work than doing it by the book.

I agree with 87County. Either you've got a kitted out shed, and can fab all the stuff, or you'll pay around $250 for special tools, and still need to fab something (e.g., I had to make an crank locking tool).

Having done it once, I wouldn't do it without the locking tools (at least pump and cam). Once the cover is off, it makes sense to do all the seals.

Don't be scared though. It's a fiddly but fun & easy job. A LOT easier than a 4 cyl transverse DOHC timing belt (90% of vehicles out there).

My crank locking tool was the passenger side chassis rail

Fit a socket to the cranfshaft bolt, the add a breaker bar with a short piece of pipe, rest it on the chassis rail and quikly click the starter.

Some will give me a spray about doing it this way, but I have done it on most of all the vehicles I have owned and never had a problem.
