Got my Mac Tools Diesel Pulse adapter..now what ( pic)

In my ongoing quest to get my timing spot on my 81 -240d I purchased a Mac Tools Diesel pulse adapter to check timing. The unit fits perfect on my 6mm line.
The static method was too hard for me I do have a degree adjustable timing light.
So UPS comes today and I did some reading ( I am in bed with the flu) I have not gone out to the car check .
I have a few questions..

1. Is the front balancer marked with timing marks
1a. Which is best to see the marks from above or below.
2. From searches I came up with 15* btdc is where I want to be.
3.Does the IP pump rotate clockwise or CW to advance or retard?

I have no noticeable chain stretch and the valves have been adjusted 135K miles
any other real time user use this tester with good results?

thanks

I don't know about the specifics of the light, but I'm curious as to how you will rotate the pump. The injection lines will provide a significant resistance... Theres a tool for just this thing and there was a lot of discussion about this problem in the millivolt timing method thread

You want to be spot on ...but have no " noticeable " chain elongation?
The chain elongation affects your valve timing and your injection timing.... if you have not figured out your elongation and figure that into this whole deal then you will not be spot on with reference to the crank and or the valve timing....
I am all for you using this nice tool because I would like to do the same in the future... but it needs to actually be done correctly as compared to ' throwing ' this high tech tool at it while potentially ignoring the basic mechanical theory and application.

Significant but not impossible resistance.... of course the next time one of them is taken off it may need to be sprung a little to get it back on ...
A longer pry bar is the secret... with appropriate cushioning at the block and IP..... and remember it only has four ... every little bit helps..

I just had to do the IP pump rotation thing (but with a Volvo diesel IP). If you loosen all of the injector hard line connectors (engine shut off of course) at the injectors the pump will rotate easily. When you have rotated the pump to where you want it tighten the pump retaining bolts and put the injector lines back on and bleed the air out if necessary. Recheck the timing.
Unless your IP has the adjusting bolt to rotate the pump as the newer ones do (or some other tool to roatae the pump while the engine is running); how much to rotate the pump is still a hit or miss thing.

thanks for the heads up

does the balancer have the timing marks on it and is it best visable from top or under the car?

I have a 300D it has timing marks on the damper. This is a devided picture the right side is a picture of the timing marks on my damper as viewed from the driver side headlight and fender area looking down between the water pump and the powersteering pump.

Dynamic timing, yummy! I've had to pay dearly for this service, perhaps time to get a little tool like yours.
