truck and forklift engine

[scrapman1077]

What is the difference between them? looking at rebuild kits and some say forklift only.

The biggest difference that I know of is the piston, 5 ring vs 3 ring. The injection pump is also usually mechanical instead of vacuum and there may be other smaller differences like the oil squirters.
