OK. Thanks. That's what I've been hearing in another group. I'm taking it to a guy who's done it before.... I'm hoping he can just replace the bearing and not the whole crankshaft. But I get it, impossible to tell until it's opened up. Thanks.

Hs anyone used these folks for a replacement engine? https://www.utvenginerebuilds.com/ And does anyone know if the Yamaha Rhino 660 engine will bolt right into my 2009 Hisun 700? I've used lots of other Rhino parts with perfect every time.

I thought the problem was electrical but I just found this in the oil filler tube. Does anyone recognize the part? I know I'll have to tear down the whole engine, and maybe I'll find the rest of it in there. Something beg enough to seize up the engine. That was the problem I was trying to diagnose.... 'Cause it's locked up. Thanks in advance. Rick

Still waiting on the local guy to get more parts. His engine needed a flywheel and head bolts and apparently they're coming from China.... I think I got this thing in January and it's still in pieces....

Was the Canada guru named Aaron? He's been helping me with TONS of advice on the Hisun owner's group on Facebook. Wealth of Hisun knowledge.

What year is that for? I'm downloading it now but thought I'd ask.... I have a 2009 700.

Just looking for suggestions or passing on what kinda worked. Maybe it'll help someone else. My seats are pretty roached so after watching a bunch Youtubes and not finding a real good answer, I tried some redneck repairs until I can afford new ones. First I trimmed the sharp edges of the vinyl down even with the foam cushioning inside. Actually, I started out doing this thinking I might just throw some seat covers on and I thought the sharp edges would wear through pretty quick. But when I got them all trimmed, the foam was still pretty swollen out of the holes since it apparently sat out in the sun a lot. (It's a hand-me-down: I take better care of my stuff.) So I used sandpaper and a block of wood to sand down the foam. It was sun-baked and harder than the underlying foam so it was easier to sand it than to try and cut it down. Once it was reasonably close to the original shape of the seat, I taped off the edges and applied 2 or 3 coats of Flex Seal black spray. Some of the deeper fills took a few days to dry completely but as you can see, it came out pretty good. I have yet to try and sit in it as the machine is still undergoing a massive engine rebuild. But at one point a fingertip did poke into the repaired spot. So I bought some Plasti-Dip spray to try again. I'll wait until I see how the Flex Seal holds up, though. Anyway. I just thought I'd tell the tale. Rick

Update: The fuel injected engine is out of the picture. He decided not to sell it. I did find a carbed engine up in Helena so we might be okay. Thanks, all. 　

Will do. Thanks. He has to order a gasket kit so we prolly won't get it for a couple weeks. Thanks, all. Rick

Thanks for the reply. The situation has changed, though. The EFI engine I almost had is out of the picture. The good news is, I found a local carbed engine so we're in the process of making that happen. Thanks. Rick

OK. New question. I have a 2009 Hisun 700 carbureted. I've found a 700cc replacement engine but it's fuel injected. is it possible to put in a FI engine into a carbed machine? I'm thinking the swap will have to include the computer, too, but what else? Or is it even possible? Thanks.

Yes, I wrote to him the other day. He answered this morning. they sold all their 700's. May get more in a couple of months but they don't make the carbed 700 anymore. Thanks.

Yes. head gasket, several different seals, water pump, piston & rings....

I'll ask him about the compression. I'm totally clueless on mechanical stuff. I'm just doing the cosmetic. He's frustrated now and taking a few days off from it. I don't blame him.... Thanks. Rick

Hi, thanks for answering. It does run but there are two main issues. The first one is apparently combustion gases are getting into the coolant system. We replaced the piston and rings and after remounting the head and putting on a new water pump we bled the coolant lines. Or tried to. Jacked up as high as we could and bled with the bleeder screw and got all the air out, so we thought, and buttoned it up. Ran a few minutes and it appeared the coolant wasn't circulating: no warmth in the hose going toward the radiator. It would get warm a little just from convection in the hose. We bled again and got tons of steam/air out the bleeder screw. This process was repeated multiple times, each time we thought all the air was out, we found more had got in and came out as steam. We did get some circulation at one point: warmth in both hoses, but it didn't last. With radiator cap off it will run and heat up and of course start pushing coolant out the cap but only for a short time and then it stop bubbling over. Eventually the engine heat light comes on and we shut it down. Brad (neighbor) started tearing it down to check gaskets again, even though he had had the head off before and replaced them. He had checked it for warping, etc., back then. While checking the water pump again he noticed the shaft had a lot of play in it and when he pulled it, it came all the way out. This is also the oil pump shaft and the circlip and roll pin that should have held it in place in the oil pump were missing, apparently fallen down inside the case. He said it would take a special brand-specific tool that he doesn't have to get the case halves apart. He thinks the oil pump is just splashing enough to keep it going but we have no idea how long it's been that way. The previous owner only ran it around the neighborhood and it never ran right for him so he didn't do much maintenance with it. He moved away and it went with the property and the new owner took it to the local ATV shop and they didn't know what to do with the brand so the owner just gave it to me for plowing his driveway all winter. But free isn't free, so I'm hunting for an engine. I have 7 Craigslist posts out and about 4 different forum posts.... Not hopeful. Thanks again. Rick
