Thank you all for the warm welcome.
Kookaburra,
Here are the prices for the main components excluding tax:
I bought the Iveco parts through
www.vexi.co.uk who sell at trade prices to customers and will ship to Germany. They are very good and much cheaper than going directly to Iveco as they buy in bulk and so can get good deals. The power take-off is a crazy price for what it is, the price below is the vexi price, Iveco wanted over £2500!!!
5801549827 Sliding prop. Shaft = £476.20
504276738 Power take-off = £1,931.10
Retarder parts through Telma:
AF30-35 Retarder-brake unit, Anti-vibration bracket, Relay Box, Hand Control unit, Light Bar Display = £2,603.00
Electronics through RS Components

I tried to get information from Iveco but they were useless, just telling me to go to a local garage. When I went to the local garage they didn’t even know what a PTO was and so I was less than confident that they could actually help with any real technical data! I approached SCAM and was very rudely told they would not discuss anything as I had an Iveco.
I did find an Iveco document that states the maximum torque transmissible by the ‘Option 8696 PTO Transfer Box Meccanic’ is 1900 Nm. So I had to assume the transfer box and PTO would not have a problem with the 350 Nm of the retarder. I also looked at the sectional views of the transfer box in the workshop manual and could see how it works internally which I was sure could handle the loads.
Modifications in the UK are much easier than in Germany. You will need to pass the annual inspection, but this is a test of the vehicle as presented. They do not check if you have changed something, just that the vehicle works safely. For example, the brakes will be tested and if they meet or exceed the required standard you pass. However, you do need to inform your insurance company of any modifications – my insurance company decided the modification was not ‘increasing the vehicles performance’ (making it go quicker) and so they did not increase the cost of the insurance.
I have sent the full details of this modification to SCAM so they could use it on their vehicles but got no reply. I have also seen that Iveco headquarters in Turin have looked at the retarder modification page on my website. So Iveco know I have done it but they have not contacted me.
It is not a cheap option but is very effective for hills and I use it all the time while driving normally. I have had a significant reduction in brake wear. If I bought another Daily 4x4 it would be one of the first modifications I would make.
Hope you find this helpful, sorry for the delay in replying. We have just crossed from Brazil back into Bolivia ;-)
