Engine Parts Remanufacturing

Do some research.

That should let you know.

Besides :Nuts and Bolts Reuse in Engine Application

Key Way Repair - Alternator

Shouldn't you already know this?

This sounds too much like homework.

The easiest method is to bring the engine to someone in the automotive recycle (scrap yard) industry and just sell them the old engine. They will then use their resources to determine first the make and model of the engine. Then they will use the internet, their own network of respected engine rebuilders and their own personal experience to determine if the engine is a prized piece of engineering or something not worth putting in any repair effort. Depending on where the engine lies on this spectrum the valued parts are removed and sold to those who want these parts. The remainder gets sold as scrap metal.

I'd call Byant crank and have them cut you a new one. be sure and add the $400 for Superfinishing

In the marine engineering area it is mainly large slow speed marine diesel engines where serious repair work is considered. Here are a few examples:

Here is the crankpin of a crankshaft that has been repaired by electroplating and then nickel capped to give added protection against wear. These repairs, including broken crankshafts are carried out insitu.

Cylinder head repairs including cleaning, grit blasting, and hydrostatic testing. Gouging welding and grinding of cracks; remachining and final inspections are all carried out. Ships always carry spare cylinder heads, pistons, piston rods, etc.

Exhaust valves from two stroke engines cleaned by grit blasting,

crack detection carried out, seats stainless or stellite welded, and

final machining and crack detecting.

Metal spraying is also used to good effect in the repair of shafting, fitted bolts, etc.

We do not worry about these types of repairs with high speed and smaller medium speed diesel engines

Very informative , this is what I was looking for .Is there any book or material you can share with me ,so that I can go through .I really want to propose some innovative technology to my company in order to promote green initiative on engine and its components.

In short I do not know of any books dealing with this particular subject.

As far as large crankshaft goes the market is captured by companies that have "flying squads" that generally guarantee to be to just about any port in the world within twenty four hours to carry out a repair. This is a specialist area and it is highly unlikely that you will find relevant material available. These companies have top quality hand picked tradesmen who are trained to work in their teams and the methods, materials, etc., employed in their work

You will probably find it very similar with the heavy marine engineering workshops that are in all major port cities that carry out major repair work for major shipping companies, they will certainly not disclose any specifics concerning the work they undertake. Occasionally you may find snippets of information as to how a firm carried out a specific major repair work that was considered newsworthy. Again these workshops have top tradesmen and guard their secrets well.

General engineering repair work should not be a problem, but that is all common knowledge anyhow.

Check out additive manufacturing. Also known as rapid prototyping or maybe Stereolithography. I'm sure metals can be done, but I don't know that they can do things like crankshafts yet. Need some sort of computer file, .stl I think.
