Grettings all,

I have a 1984 300SD with 263,000 miles. I want to check the injection pump timing. The chilton manual states that diesels prior to the '84 model are set to 24 degrees BTDC. It states that for the '84 300SD, timing is at 15 degrees ATDC. Is this correct?? It seems that after top dead center is way too retarded for the timing. The manual also states that the 190D is set at 15 degrees ATDC. is this a misprint? What are the actual specifications for the timing on the '84 model 300sd? Thanks in advance for the help!
