Gentlemen
the next update:
I started cleaning up the alloy engine covers :
The alternartor cover showed signs of a fall, deep scratches...
After grinding with sandpaper 120, 180, 240, 400 this was the result:
No more scratches...
And this is how it looks after polishing:
So you see that a lot is possible with the correct tools and with patience.
The other covers are treated the same way with more or less the same results.
They wait to be covered with a coat of the special varnish.
I also spent a lot of time on cleaning the cylinder head.
After about 2 days the results were good enough for me so I started to assemble it.
The valves were all lapped and then the assembly commenced.
Just an advice for people who do this for the first time:
don't forget to put the spring dishes in the head BEFORE you put the valve stem guide caps on!
If you don't do it that way, you can't put the spring dishes in after the guide caps are in place and you'll have to remove the caps and thereby causing damage.
When I put the valves in the guides, I always use a bit of special grease on the valve stems.
After all the valves are installed in the cylinder head it's time to shim them up.
Keep in mind that when lapping the valves, you can have a difference in the thickness of the valves and that you have to adjust the shims to get the correct amount of play.
When doing that with the head off the engine, always install one camshaft at the time, never the two at the same time.
If the two camshafts are installed at the same time, there's a big chance that an exhaust and an intake valve can be opened at the same time and that they damage each other because there's no timing between the two camshafts.
After all the adjusting the cylinder head was prepared for instalment.
The exhaust studs were mounted and the intake rubbers were also mounted.
It's easier to do it at this stage, you have all the room you need to secure them tightly.
The other camchain parts were installed, the gaskets put in place and the head was mounted.
The timing was set and this is the result of a days work.
More to come next time
