Thread: should i re-do timing belt 300tdi

Well, for peace of mind I would be inclined to do another replacement job knowing only the contadictory facts that you relate. All 300tdis need replacement 60k-70k, the early ones were the ones that gave most trouble - 98 models should be OK (but still adhere to replkacement schedule)

Just a belt change shouldn't cost that much.... talk to a competent LR specialist workshop and see what they recommend and offer.

Yes, there are other parts that should be replaced on a belt change (eg. idlers & tensioner bearings, water pump etc)

To help us to help you - where are you???
at how many ks was the belt supposed to have been last replaced???
do you a workshop and tools???
and do you feel sufficiently mechanical competent to dismantle it yourself???

If the updated pulleys have already been fitted (which they should have, many years ago - it was a recall item I think) you probably just need a new belt.

Read this link: DIFFLOCK - 300tdi Timing Belt Change and look for point 12.


12. Inspect Timing Cover and Belt

With the timing cover removed, inspect the inner surfaces of the front and rear cover for any deposits of black belt dust and debris or oil contamination.

If there is oil contamination, you will need to replace the camshaft and crankshaft oil seals in the rear timing cover. See our special Difflock Guide to replacing these in the next issue.

If there is a significant build up of black belt dust and debris, this is an indication that your belt is badly worn and that possibly the 300TDI engine requires a modification kit to be fitted. (Note: You do NOT need to fit a modification kit if your belt shows no signs of excessive wear, regardless of VIN Number).

..................not quite so simple if he doesn't have (or have access to) the tools to lock the crankshaft & undo & remove the harmonic balancer (pulley)

Mike,

300tdi that late in the run should be sorted.

speak to any major LR dealer service department and ask what is involved with the timing belt service. If idlers need to be replaced and yours only has the belt changed then you have something to complain about.

One of the mechanics on the list that is not on leave will come along soon and give you the good oil.

Mike,

There are heaps of opinions on this, but I can tell you that I NEVER just replace the belt. ALWAYS the tensioner and idler, and obviously any seals that look like they are weeping. Think of it this way, the idler and tensioner have at least 80K odd already, they WILL not last all up 160K at the next belt change. Obviously there are those that don't replace them, hoping that any warranty has run out before it seizes and breaks the belt they fitted

Do it once properly.

These things are so bad for the belt tracking over and wearing away the edge and/or the flange on the drive pulley. Any wear in the idler pulley assembly is not worth the risk - even though it has the late type idler assy, they are a consumable item on 300Tdi.

I also like to recommend replacing the harmonic balancer as well although generally most are ok at the initial 80k mark and need doing at the second interval.
