I have been rained off today so i thought i would investigate the cam timing!...So off with the radiator and timing cover etc..I checked and re-checked a couple of times and as far as i can seen the cam is timed in on the inlet at 103 degrees.I need to find a figure for the exhaust so i can check to see if the phase is correct.The front end has a duplex chain and a nice front pulley so thats good i reckon.
So with some time to spare i decided to pull the head and see what was going on in there.It is a 1600 and is on its first oversize.These are the pistons.Can anybody i.d these please?

I then took a look at the head.Now this really looks the part internally.It has been ported to a nice standard and has bronze guides.Here are some pics.Not the best but its hard to photo a port.
A pic of the valves.

Nice looking head Adrian. The pistons look like standard bowl in piston, cast ones. The number on them looks like an AE/ Hepolite type number (20850) somebody with more knowledge than me will be able to tell you if they are 1300 or 1600 pistons by that number or by the size of the bowl in the piston, a 1300 will have a smaller bowl than a 1600.Gone to the Dark Side but still lurking!

Or even 20550. I notice in the Burton catalogue, there is a Nural (formerly AE) piston with a number 20552.Gone to the Dark Side but still lurking!

Well now that the engine is out i have decided to pull the box out also as the speedo drive was not working.
I removed the bung...Damn!!
No drive fitted
I rang quaife-ex and they said that it would be a big/expensive job to modify my gearkit.
So i have bought one of these from rally design.
Its 80mm dia and should look ok with the jaeger rev meter that is fitted.
It has a hall effect sender that picks up from one of the disc mounting bolts.

I managed to get a new bearing for the gearbox from the local bearing factor for the princely sum of £7.20..Thats now fitted and the box built back up with new seals and gaskets.I hadn't planned to do this but glad i did as i now know it will be right.
On further investigation the spigot in the end of the crank consisted of a piece of bronze that was 4mm bigger in diameter than the input shaft of the box.This has probably not helped the situation.
I have a needle roller bearing type and have fitted that.
So the box is now ready to fit.
