So I am looking at doing a restoration project on a D7e 48a and I thought the best place to start would be doing a rebuild on the getting tired engine which I believe is a D339. What is a good brand of rebuild kit or are there any to avoid or is it best to stick with OEM parts that is if CAT still make them?
Can't really help with your question regarding engine parts but a suggestion would be to register on the ACMOC forum and post the same question there - https://www.acmoc.org/
I think Cat have a parts thing going for older models don't know wether its in NZ would pay to ask the local dealers or as NIge says go to ACMOC forum. Sounds like a cool project keep us all posted. There is a group on face book called NZ Road Transport & Contracting, in that group is a bloke called Paul Clarke who has a few 8s & 9s done up who might have some better info on parts and where to get hem from.
Thanks for the suggestions I will check both of them out and continue to update on here along the way with some photos as well.
You better hurry, Wheels at Wanaka is on in 18 months.
