Dayco, which are OEM, and exactly the same parts and quality you'd get from an LR dealer

I replaced my 3.0 D4's serpentine belt at 100K kms with a Dayco belt. After another 80K kms I removed the Dayco belt because of its cracks and refitted the original belt whilst I waited for a genuine LR belt. I've had many Dayco belts fail on my farm machinery so now only ever use genuine equipment manufacturer's belts.

If you bought a Genuine LR belt kit, it would have been a Dayco belt and tensioner inside the box

That doesn't guarantee that the quality of a Dayco belt bought from a bearing supplier for the same application is the same quality.

Why would Dayco make more than 1 quality of belt for the same application?

The only differences between a belt supplied by an LR dealer and a Dayco KTB694, is the manufacturers part number printed on the belt

Time to do some digging....

It wasn't the D4 but my MY03 D2a to which I had fitted the Dayco belt at 100K kms which didn't last the distance of the original. Therefore I can't comment on the longevity of a Dayco D4 belt. At 175K kms the D4's original belt was changed for a non-genuine belt at the same time as the camshaft and HP fuel pump belts were changed and is still going at 260K kms in my son's ownership.

That would make sense, the aux belt arguably has a tougher time, dealing with water/dust etc, whereas the Cambelt is mostly isolated from those elements, especially if the cr goes off road

Does anyone please know where the best place/ lowest price to get a Land Rover compatible Crankshaft Pulley Removal/ Installer Kit for 3.0 TDv6 L405 (and if you do, could you please post a link to the tool)?

And is labour time for the job of about 5.4 hours about right for a competent mechanic?

Note - the full job is said to require removal and refit of fan belt, cam belt, fuel pump belt, idle pulleys and coolant. Although I’ll be guided by those more knowledgeable.

Thanks in anticipation.
