I take care of a nice 87 300SDL with 300Kmiles.
Is there a good method to set IP timing without using the Bosch tool.
Motor is sound, good compression 32 bar still, new injectors 140 bar. I repalced the timing chain lest week and now I want to set the IP timing.
I guess that start of delivery should be around 24 to 26 degrees BTDC but I am not quite sure. Is there anyon who knows the data and the best method I can do in my own garage. Thanks

You need the RIV tool to check the timing. It is availible to rent for a small fee off this site.

IP timing is 15+/-1 ATDC.

........what Hattie said.

Not to be confused with start of delivery.

Thanks.
Is there an equivalent of the 15 degrees ATDC (RIV) to the 'real' start of delivery with the dripping method? Like for instance
15+/- 1 ATDC (RIV) is equivalent to 25 +/-1 BTDC (real injection time)

I know that the older Mercedes diesels were set at around 24-25 degrees BTDC
But I am not sure about the 300SDL Turbo. Does someone know about this?

I don't believe there is a "drip method" for the 603 so, this information may not exist.

The M pump may have a different characteristic with regard to the start of delivery.

Furthermore, the inaccuracies of the drip tend to strongly favor the use of the RIV for the 603.

How can I rent the RIV tool on this site?

The forum is on the first page.

Go to item #14........the RIV tool. Contact the owner "Crazy Banana" via PM.
