This morning I was helping a friend of mine replace the alternator on his 2000 4.4. He's not the most mechanically inclined, so I was trying to help him save $1000.
Anyway, the job was going smoothly, and I had the new alternator installed and was tightening up the bolts.....he wanted to help, so I let him step in to tighten up the remaining bolts-----big mistake. Next thing I know, I hear a giant "crack". He tightened it up wayyyy too tight, and I was really hoping he had just sheared off a bolt, but after I took everything back apart, I discovered he had actually cracked a piece out of the housing that the alternator fits into.
Long story short, I don't think this can be welded....if anyone disagrees let me know. Can someone look at this (pic one shows the broken housing, pic two shows the piece that broke off, and the last is the link to Realoem.....is the part listed as #1 in the diagram the part he is going to need? Thanks for any help, advice, or condolences.
