Hi All
Things are continuing to progress on the van. The front disc brake conversion still has some work to be done, but is nearing completion. You can check this out elsewhere for now at

I thought I'd drop the front suspension out and start cleaning and sorting that out as it was covered in a combination of oil and grease in places and encrusted in years of built up mud. My van came from the country and would have spent some of its time on dirt roads with much of the mud still there. This build-up is sometimes an advantage as is sets like cement and tends to seal the underside, especially when you add some oil from a typical British leaking motor or gearbox. Over the years I have had Range Rovers, a Land Rover and a number of Triumphs that all had this wonderful anti rust system. The only problem was that the oil never spread far enough to protect the sills!
After having a good look and a read of the manual it was apparent that to remove the front end complete I needed to unbolt the top pivots from their mounts. I knew that the springs would need to be compressed for this so the top arm was off the top bump rubber. The manual mentioned some special Churchill tool so I made something up myself. I'm not sure if anyone has done the same, but it proved very simple and effective, consisting of some 10mm threaded rod welded to some 20mm box section with a hole drilled through it. Total length is 300mm from centre of bolt hole to the end of the thread.
It fits in as shown in the picture below with a large washer and nut under the lower suspension arm. Doing up the nut compressed the suspension enough to lift the top arm up off the bump rubber and was now able to undo the pivot mounting bolts and found it long enough to drop the suspension so the springs was loose.
Before this I had to disconnect a number of ball joints, which I was not looking forward to as they always seem impossible to get apart with out destroying them in the process. To my surprise it only took a few hits and they were apart.
After undoing the necessary mounting bolts, which amazingly came apart easily once I'd found them buried under their mud encasing, it was out and time to see what we had. I already knew that the right hand shock bottom mount had parted from the shock body so I chose to start there, and quickly realised that I also had a cracked spring. The last coil was still cemented into the lower spring platform with the missing part of the shock absorber.
I set to and chiselled through the mud and after 30minutes finally got the missing part of the spring out.
I then removed the broken shock absorber which otherwise seemed in good condition. It was here I made an interesting discovery. When I purchased the van I had been told that it was a 1965 model, but on the body for the shock absorber I discovered a manufacture date of 2/62. I pretty sure that in Australia these vans were made from knock down kits, but it seems to me very unlikely that they would be fitting 3 year old stock to a new van. So I suspect the van could be a couple of years older than I thought.
Does anyone know if the guy who does the Commer dating has been able to date knockdown Exported kits?
That’s where I am up to at the moment. Where I work we have an industrial parts washer that they use for cleaning large compressor part. I am very keen to try this out with the suspension components once I have them all apart, it could save me a lot of time and effort. The ball joints all seem in good shape and hopefully a clean and fresh grease will be all they need plus all the other bushes etc seem good too, as whoever operated the van originally wasn’t afraid to use a grease gun.
Cheers for now
