The job is done and the 190 is running nice and smooth. Mind you I haven't taken it on any road runs yet so it may well blow up on me yet.
The belts that were on it were not in the greatest shape as mentioned above.
I suspect that the rear belts were the originals as they were Rover branded and were quite loose. While I had the pulleys off I replaced the rear cam seals which were all weeping. The front belt was very sloppy. Whoever changed it last hadn't got the tension right and the top runs between the water pump and the pulleys were very slack which can't be good for the cam timing.
I got most of my parts from a well known retailer's "Cam Belt Group Buy" and have to say I wasn't overly impressed with the quality of the parts. The water pump needed a lot of filing of the mounting holes to make it fit and the mounting bolt for the tensioner had too much thread on it's shank compared to the original, and the spacer washer looked like it came from a DIY store. I used the original bolt and washer instead but this doesn't give me a lot of confidence in the parts. The front belt was a Dayco, and I was surprised at how tight it was once fitted. Definitely tighter than the belts I had used on my Freelander V6. It could be that the roller on the tensioner was incorrectly adjusted out of the box but all of the manuals say to leave it alone so I did.
One other thing I found was the cam pulley bolts which came from Rimmers. Some were marked with an M and others were marked Pooja Forge. The MGR packaging said "Made in the UK" so I know they were good quality!
One last parts issue was the front cam pulley cover I bought off E-bay to replace my broken one. Of course I needed a right and they sent me a left. I wasn't about to leave the car apart while waiting for a replacement so I just made up a little alloy part to cover the hole. Problem solved.

I also installed a new water pipe manifold on the subframe. No bones about the makers of this one as the label was in Chinese, but the manifold and hoses fit perfectly. It even had the rub reinforcements as per the original.

I'm glad the job is done and I certainly hope I don't have to do it again.
I am looking forward to getting back to work next week to have a rest!

I know that feeling ! Whilst fitting and timing the belts is easy enough , the frustration comes from the amount of stuff you have to remove to do the job

I hate to say this Rich but the tensioner pulley needs to be adjusted according to the INA instructions in conjunction with the plunger setting.

Simon, what are INA Instructions?
The car is running great now, much better than before the belt change, but I will pull the belt cover off as soon as possible to check that the tension isn't excessive.

INA is a brand of tensioner pulley for the KV6. Someone on this forum found an INA document describing how this part should be set-up after fitting. MG Rover's official workshop manual to dealers does not include any guidance on pulley replacement or set-up and neither does the much lauded Gates brand.

The pulley can be moved eccentrically and fixed by means of a bolt whose position is not preset by the manufacturer and is supplied loose. The pulley needs to be adjusted to a precise position using an 8mm Allen bit before removing the pin from the tensioner plunger. This procedure ensures that the correct tension is applied to the belt.

INA Service Info: Tensioner pulley; important information for correct assembly.

Thanks for that Simon.
I only referred to the factory and Haynes manuals.

As Simon has rightly pointed out, A lot of KV6 's are rattling around with the tensioner incorrectly set. I would be concerned if you fitted it straight out of the box without following the data sheet. Not what you want to here but many people have commented on them not being set correctly.

If there were a data sheet with the tensioner that would have helped as
the manuals (I had the factory manual, the Haynes manual and the factory Freelander manual open as well) say nothing about tensioner adjustments other than "It is set at the factory so don't mess with it or very bad things will happen".
The Schaeffler instructions are very straightforward. I wish I had seen them before as that may well have saved me an extra day's work.
At least if I have to strip it down again things will come apart easily.
