I have drilled the head to accept the new limiter.
The book doesn't call it, but I've used copper washers to avoid any eventual leak and some Loctite on the threads.
New limiter in the block.
Some grease on the O rings to keep them in place.
Cleaned up the t
ensioner.
I first followed the book as far as installing the chain,
tensioner and cam shafts, but when I worked on the B head, it was easier for me to install the chain first, the
tensioner and then the cam shafts.
Below,
tensioning the
tensioner at 14 ft/lbs
I have marked the rotation of the chain. This will be useful later in order to set the cam shafts.
Made an extension for my dial indicator to set the
TDC.
To increase precision, i have marked the casing when the needle of the dial indicator stopped moving and then when it starts moving again. The true
TDC as far as the
crankshaft is concerned is in between the 2 marks. The difference is very
small dough.
Setting the intake cam shaft by
turning the cam shaft in the same direction of the chain. On the 2.7 liter, the valve is set at 1mm down and on the 3L it is 2.20mm. I wish the book said that earlier instead of in the check timing section. I had to re-do it. When the timing is set correctly, a mark on the shaft caps are aligned with the long mark on the cam shafts.
I could not loosen the rings on the cam shafts. After a call to Dave
Burnham (Thanks again, Dave) I have
grinded a chisel and by whacking the ring in the wise, it finally
loosened up. Here is the wrench I made form two 2 inch pin wrenches. The other one is a
grinded 26mm open spanner. To hold the cam shafts in position, I used pieces of leather between the caps and the cam shaft.
Setting the exhaust cam shafts, which have to be done in the
opposite direction than the chain. The value is 1.3mm in both 2.7 and 3 liter engines.
The valves in balance. The light is in the exhaust opening. The exhaust valve is closing while the intake is
starting to open.
Working on
the B head now.
Of course, the chain is turning in the same direction than the A head, but it seems that it is the
opposite, since it is pulling the exhaust cam shaft first. I marked the direction to avoid any confusion.
Stating to look like an engine.
Now, I am ready to set the timing on the B head...
