This is the first bike I own that has a Speedo.

Removing the timing cover.

Oil pump etc.

Lots of buildup of excess fluid gasket - I wonder how the sludge trap looks.

Is it normal to have them to much off center?

Its going to be a real hassle to get this pinion off, It has bee grinding the crancase!!

Removing the Drive side cover.

Engine removed and inspected

Cylinder + piston + Head looks fine

VB without motor.

My temporary workshop (in 5 degrees freeeeeezing).

Transport to better locations

Now I need to dismantle some of the last bits, and then its all going to be properly cleaned, for final inspection.

This shock absorber arrangement is ok, even though they dont seem to look right.

The Assembly:

The parts are now properly cleaned and ready for inspection and assembly:

It was quickly obvious that a new cam bus was needed, so the old one was removed.

Barrel looks great

Placing the Cam bush with a screw and center spacers to assure a straight pull, and it does not jam on the way.

Reaming the Cam Bush - Please note the bush spacer that keeps the reamer in line, and does a perfect job. - The Reamer Was borrowed from Henrik Larsen from the Danish Ariel Klub

Now I have to shim the crankshaft with the crankcase.

Just a moment-photo of my tool shed - its pure pleasure to do Ariel there - When its warm (-:

The two cams, The old one have to be redone somehow - The new one was purchased from Jørgen Andersen.

The halfs have been prepared and the shimming is finished, so the halved can be put together for good.

The halves are carefully cleaned with alcohol, and the sealing compound is put on both halves.

The halves are put together, and the end clearance is checked once again.

Now its time to fit the CAM and the cam followers. Please make sure the lube before fitting, as the first starting of the engine will be without that much lube, until the oil is circulating properly.

I made some slight modifications to the gasket, to make it fit the timing side - Otherwise it would not be a perfect fit. I took off aboit 1-2 mm at the side.

Make sure to place the extra gasket at the oil return suction joint. (Use very little fluid gasket on each side to be sure)

Putting slight amount of fluid gasket on the timing box. 

When the timing halve has been fitted you should make a test to check weather the return suction joint are air tight - I took a rubber hose and placed on the suction tube (near the sump plate) and placed my finger on the hole where the oil pump is fitted, and started to suck. This should be completely air tight.

Next was the cylinder barrel and head.

If the timing chain are the endless one, it has to be fitted with the sprocket, other wise its not possible to get it on.

The ignition and dynamo is inspected - I checked that it was functioning bu getting a electric jilt when turning it by hand. (It can have other faults, even though this is possible)

the engine is ready, now I just want to make the bike roadworthy - I found that the rear wheel bearing was badly worn, so it had to be changed. (Don't worry, it will also have to be painted at some point in time)
