What is the difference between a H150F and a H151F gearbox fitted to the 1HZ Diesel engine. Some heavy handed person has cracked the case at the filler plug. Now leaking oil

Wayne AFAIK,the difference is that the H150 is the 1HZ box and has a slightly lower gears in 1st and 2nd

I assume that it is the alloy box as you would be superman to crack the cast iron box by hand.
Can't it be welded if it is only the raised section for the plug? It's not really structural.
