Abandoned Cam turning tool

vitesse · 17th February 2022, 16:11

Look what I’ve found: an original 18G 1747-4, I now know how to make a certain Canadian jealous.
Was out to the local scrapyard, not too much snow and plus 1c, to get a replacement SRS side sensor. Not too bad a job, final check for tools before heading home, but what’s that on the floor over there? It looks like, can it be … God I’ve been searching for one for my otherwise complete set of genuine Rover cambelt tools. Happy days

Jealous Canadian here

Well done!
That was a lucky find.

Comparing the picture of your factory cam turning tool to a cam pulley insert gives an idea.
A spare insert could easily be converted into the tool by cutting off the ears, threading the center hole and screwing in and loctiting a bolt to take a wrench.

The only advantage my home made tool has is that you can slide it onto the cam and leave it there without fear of it falling off.

Just to clarify for those who haven't seen the original thread here is my version of the turning tool made from a socket that slips over the end of the cam and has an 8mm pin inside that locates
in the notch in the end of the exhaust cam to allow it to be turned into position.
The cam holding tools have had their hex ends which are no longer needed cut off to make them more compact.
These tools make the awkward job of fitting the rear pulleys much easier.

Nice that you and Trikey appreciate the rarity of the find, most others I suspect don't know what it is. I can honestly say that if I had found a chunk of gold the same size I wouldn't have been that happy.

Thanks for the picture of the insert, I've never seen the back of it. Your plan could well work and provide an alternative source for this most elusive part.

Keep well

For such a small tool it sure makes the job easier.
It's really a shame that the people manufacturing the aftermarket
tool kit didn't supply the turning tool instead of machining the hex
on the end of the holding tool. I'm sure the cost would have been
about the same.

Bloke here just managed to break two camshafts with his universal kit, although don't really get the full picture as he was trying to undo a camshaft bolt but the holding tool slipped, it involved fitting the universal front holders which have a round peg into the camshaft's square-ish slot.

Looking forward to seeing a picture of your ear-less adapted gear holder when you find the time (if you've got a spare).

Keep well

The damage can occur when the holding tool cocks when fitted putting pressure on one side of the slot in the cam. Being as long as the handles are makes them quite awkward to work with.
I had this happen to me once on my old Freelander and it broke a chunk out next to the slot. Luckily there was enough left of the slot to still locate the tool. That engine must have been jinxed as when I got it the intake cams had a big piece broken and had to be replaced. The last guy had just put the piece back and torqued the pulley bolt down hard.
An exhaust cam was also badly broken the tool would no longer fit so it had to be replaced as well. The same head had noisy tappets so in the end I took advantage of a big sale that Rimmers had at the time and bought a new L/H head and a second intake cam for the Right head. The pulleys had a lot of marks painted on them so I assume the belts had been done without tools and the guy had taken all of the belts off at the same time and had to try to turn the cams with whatever he had handy.
I don't have a spare pulley adaptor but they are only 5 quid so I may add one to my next parts order to play with.

This is the broken intake cam from the L/H head with the piece sitting in place

And with the piece removed

This is the R/H head. The cams were in terrible condition. By the colour of the broken end of the exhaust cam you can tell it had been broken for some time, and check out the excess sealant on the cam carrier. The oil channels in the carrier were almost completely blocked.

Shiny new head on the bench next to the old head
