The early CA95 was fitted with a tach drive and you can't do away with it unless you change to the later head and camshaft.
Before removing the 3 screws that are visible, remove the cover where the cable would go in if a tach were in use.
Next, withdraw the worm (screw) that drives the cable, it just pulls out.
Then slide out the tube that the worm spins inside of, this section is on a keyway in the main housing, it should just slide out.
When these 2 components are removed, Remove the plug that gives access to the fourth holding screw which is inside the tacho drive body, this is just like the top screw on the cam end blanking plate of the later model with no tacho drive. remove all four holding screws using a long impacter on the internal one. If you damage this screw you've got problems.
The body should then pull away from the head but you will note that this tacho gearbox body is also the bearing for the camshaft and you are left with a gapeing hole in the side of your head.
When you rebuild this section, it's a good idea to replace the internal screw with an allen bolt, they are much easier to remove.
If you deceide to go with the later head and camshaft, send all your old parts to me and I will despose of them in a safe and humane manner at no cost to yourself.
Sam.
