Hi all. I just acquired a 1995 853 with a dead engine. I want to start by getting a good service manual. I usually like to have a paper manual but I don't have time to wait for the dealership to order the thing in. Is there a good manual on pdf that anyone here would recommend? The engine is out of the machine and completely disassembled. The pistons are scored and the crank looks like it may have spun a bearing. The guy that I bought it from had a service tech at a local shop look at it when he noticed it was running really rough. When the guy went to the shop to check on his machine he had the engine completely dismantled. long story short he never got it repaired. I figure I have three options here. 1 I could bring the engine in and have it rebuilt/repaired at a local shop 2 I can order a rebuild kit w/ crank from ebay for about $1300 3 I have found a long block on ebay for approx $3800 including shipping Both 2 an 3 is basically using parts made in China. I'm not so sure about the quality of the parts and I was hoping someone here has had experience with them. I am trying to get this done as economically as possible here so the Chinese parts look like they may be my only choice - the engine shop I called has yet to call me back and I suspect it will be a high quote as it is pretty busy here in most shops. Any advise here would be appreciated. Loren

Don't give up on that crankshaft just yet. If you have the Isuzu engine and have been told the crank is hardened and can not be repaired, that information is wrong.
Contact Crankshaft Supply Inc in Minneapolis, Minnesota. Tell them what you have and get a quote on having it repaired.
My brother did a job on a 853 a few years back. It had a spun bearing and he was told the Isuzu crank is hardened and can not be repaired. He took it to Crankshaft Supply and they annealed it, welded the journal, machined it and re-hardened it. He got it back in about 3 days with a new set of bearings. The cost was much cheaper than I thought it would be.

I've been able to pull mine with someone in the machine hoding the steering levers in the direction you're pulling. Cranking the engine helped too.

You shouldn't have to settle for China made parts for that engine. To be truthful Im not sure where to source China made parts for an Isuzu. Parts from Japan are a whole different story. China and Japan and not the same. The intended use would make the determination for me Price wise. If its a machine that will see thousands of hours it would get all new OEM parts no exceptions. If its a hobby/homeowner machine that wont see a thousand hours in the next 10 years I would take a chance and save some cash. Cranks can be repaired but for a crank that costs less than a grand I wouldn't bother because I have seen too many problems. I also rarely buy complete kits when a repair is all that's needed. Check the tolerances and see what can and can not be reused. A used runner may be a cheaper alternative in the long run.
I've gotten some quotes on rebuilding the unit which don't seem to be too bad so I most likely will go this route. I did see a rebuild kit on ebay that claimed it was not chinese parts. Now for the manual are there any recommendations?

One of the members here has a number of electronic Bobcat Service Manuals. Look-up "Old Machinist" in the member list area and send him an email requesting a copy of the 853 manual.
If he has it, you should hear from him.
Thanks TriHonu. I was able to get a copy of the manual. I found a used engine on ebay from a Mustang 960 that matched what I needed. I have the unit up and running again. I have to do some work on the electrical now because there is no alarm or lights when I disconnect the oil sending unit. The water temp gauge does not read and the amp meter does not show anything either. I am going to try to fab up some windows and a cab door next. And possibly get a heater rigged up in it. Its been -30c here in the last few days and its not fun clearing snow in an open cab.
