 Engine rebuild or longblock

Have you done research on the co$t to do either? Rebuilding can sometimes cost more than "repowering" (industry term for installing a new or different engine than it came with).

I had a small Perkins 4 cylinder diesel in a small skidsteer loader. Parts cost about $800. Labor was in excess of $5000. I sold the WHOLE machine to my buddy for $5000 and he's rebuilding it himself.

I would find the engine series or model number and google it and see what comes up. Then add "repower" or "repowering" and there may be another engine that will work---this happens often where, say, a Briggs & Stratton motor can be replaced by a Honda or Kawasaki or Tecumseh.

Be careful not to get rid of your current engine if you find a similar engine to what you have now for several reasons: sometimes you have to retain the oil pan, muffler, throttle linkage, intake, exhaust manifold, fuel cutoff system, and a miriad of other parts. For example, my particular Perkins was used not only in skid steers but generator sets, refrigeration units on semi trailers, marine applications, forklifts, Ag pumps, etc., etc. Therefore, each application requires certain parts not used in another. And sometimes these engines were run on propane which uses a different injection setup as in forklift applications.

Another source is www.surpluscenter.com Several members here have had good results buying a new engine from them.

You may even consider dumping the current machine and buying new---take that $5000 or more and apply it toward a new or newer one. Just a thought.

We've found that we can rebuild most everything! That doesn't mean that it's always the best way to go. It can often enough cost more then the engines can be purcahsed for that are new replacements.
