I live in the middle of the jungle in Papua New Guinea, and I am after engine specifications for the 4D55 and 4D56 diesel engines. I have a 4D56 engine, and a 4D55 engine overhaul kit available to me, will it do the job. I know the bore dia are the same, just stroke is different, but I also need the crank main and b/e specs, along with other engine specs. Can anybody help me out here. Cheers

Lordtrunks,
Many thanks for your offer, greatly appreciated. I had a guy in the UK send me full engine specs and service info this morning for the 4D56 ( 2.84 mb worth), so anything I can get for the 4D55, turbo or otherwise is great. Looking forward to receiving the info. Again, many thanks for your help, and have a good day.
Regards
Graham
