Hi,
We are rebuilding a LR series III Santana 2.25L Diesel. We got new values, pistons, bearings. One piston ring was broken and damaged the piston. We also got the injectors refurbished. So we are quite curious how this thing will run.
This is the first time I worked on a Diesel engine, so couple of things are new to me.
I marked the chain and the sprocket to make sure it when back up in the same way. I found (later on) that the sprocket on the camshaft and be fitted in 6 different ways. In the manual I read about an EP mark on the flywheel. I did see a AE mark on roughly the location where the outlet valve of cylinder 1 is at its maximum. Is there another way to check? If nothing else I can mount a angle dial on the crackshaft pulley and just check the opening and closing of the inlet and outlet valves using a micrometer on the tappets. Any suggestions?

Also on the timing: I read in the manual to use a special tool to set the injection pump. Are those easy to obtain? Or how do you guys deal with that.

Hi,

Just wanted to report back. Here is how I solved the puzzle. From internet I found a circle with the degrees 0 through 360. On that I indicated the in and outlet valve angles, which I found in the book. Then I glued the printout of this on the crankshaft pulley, while aligning the 0 deg with the TDC on the flywheel. With that I can (using a micrometer) see when values open and close. There I found that the values open and close about 9 deg too late. I also found the mark on the flywheel at which the outlet valve of cylinder1 should be opened at its peak. Since all angles were about 9 deg late, the solution was easy: I had to move over the camshaft chainwheel by 1 teeth. Checking it again, it was spot on. Ptoblem solved.

Thanks for the follow-up! Can you provide a link to the wheel you printed?

 

I must say I did not keep the document. What I did is the following:
I loaded a picture of a circle with degrees in word and drew the lines and the 2 semi-circles in. But I can make it again and put it in this post.


I will remake it with a little story to it for others to use.

As promised I attached a word document with a valve diagram that can be glued on the front-side pully to easily verify the position of the camshaft.
