Ancillary Belt - Tensioning weirdness

All the stuff I've found suggests that there is an automatic tensioner on most/all of the diesel engines in these - I'm not sure that I have the original engine (the plate has been removed or corroded off).

But anyway, here's the set up on my van:

None of these idelers have any movement in them.

The belt I got to replace is 40mm longer than the current belt.

https://dispatchexpertscudo.org.uk/foru … php?id=651 has a diagram of the belt routing and it looks like my (1) and (2) are the same size, but swapped round. And where my (1) is should be the tensioner.

I have refitted the old belt (but it needs replacing) but cannot easily source the same length for my 'setup'

Lots of things on this engine make me suspect it's been finagled with in the past (the waterpump was different, which meant they'd hacksawed a bit off the top-back timing belt cover - more on that in another post).

Thoughts/suggestions? (I had considered using a larger idler (taken from the timing belt replacement) in place of 1 or 3).

Is there much movement in the alternator to take up 40mm of slack (I guess 20mm of movement for 'there and 'back')?

Re: Ancillary Belt - Tensioning weirdness

Looking at the image, I wonder if slackening of the nut between 1 and 2 will allow the 2 idler to move and take up slack...

This is the same as my 1.9D DW8B 2006 automatic tensioner.tens.jpg

Yeah, there's nothing obvious like that on mine - Eurocarparts gives a ball-park figure of £120 for something similar - I'll try the local scrappy first!

Re: Ancillary Belt - Tensioning weirdness

OK, a bit of digging around and I found this thread:

https://www.berlingoforum.com/thread-16239.html

This seems to be the setup I have and also lists a belt which may fit, 6PK1388 - going to give it a go!

Re: Ancillary Belt - Tensioning weirdness

Sorry ..... For whatever reason I've arrived  late ......

I do believe some DW8's had manual belt adjustesrs fitted ... Which would make it your N.O.2 in picture ......

Just like you've now found out from a post on the Berlingo forum from our very own kenbw2 ...................




Mine must have the auto tension on it as I bought IIRC a 6pk1440 and it lay in back of van for ages............
which then had to get fitted about 2 years ago ... when coming across Ranoch moor the belt fitted let go and then we hobbled into the green welly .......

Oh wow! I'd forgotten about that post. What was I doing in a Berlingo forum?  neutral

Re: Ancillary Belt - Tensioning weirdness

@KenBW2 - on that Berlingo forum you put "Oh and yea, looks like my old belt was too long at 1438mm. The new 1390mm one leaves plenty of room between the pullleys." Which is exactly the same problem I have - I'm glad you've point me to a shorter belt that will fit as I don't fancy making the adjustment to the level where the two tensioner/idlers are almost touching!

Related - does anyone want a belt that is 40mm too long for me to use? :-)

Re: Ancillary Belt - Tensioning weirdness

Yes! I remember thinking my pulleys were awfully close to each other. I like to add my findings for future people, glad to see it helped!

Re: Ancillary Belt - Tensioning weirdness

11 quid Dayco belt turned up from eBay (Evans halshaw stock label)

All fitted in about an hour (including wheeling tools out, jacking up the van, wheel removal, etc - and reverse when fitted)
