HELP, reringing my engine, and finding problems

Recommended Posts

I would go on the lose side myself, as things wear in they will get tighter on the clearance, therefor if you have a tighter spec to start with as valves wear and such it will get even tighter and throw you out of spec. In a perfect world the valves, seats, cam, shims will wear evenly and not cause an issue. But we all know there is no such thing as a perfect world

When I put it back together, everything was tight, so I think I will go with loose.

"But we all know there is no such thing as a perfect world", you got that right, for sure!!!!

Know of any dealers or any one else that has shims? Found this so far, http://stores.ebay.com/HIT-THE-GAS/_i.html?_nkw=shim&submit=Search&LH_TitleDesc=1&_sid=120606839

Still looking.

Thanks,

Jeff

Jarrad would know better than me. Jarrad you are assuming Kinarfi is going to get some miles out of the engine before he needs another rebuild, LOL!

I fully agree with Jarrad. Stay to the loose side. The most wear will more then likely be the valve seat slowly over time seating farther into the head to close up clearance.

Just about, after I got the head revalved, intake only, they couldn't adjust the valves because the couldn't get the shims or grind enough off the valve stems to get the clearances I need, so I took the head and measured gap using a 2.30mm shim and then calculated what size shims I needed and sent the shims and the specs to Lenny and he ground the shims and has put them in the mail to me. Plan to post a bunch of photos of the changes I have made while doing this. Moved wires, rewired and redid some of the hoses, had already changed the fenders and put a wall between the wheels and motor to keep thing a little cleaner, added a heat shield to the header to protect the shocks and the limit strap from the heat, moved the oil pressures sender via hose to the other side of the engine, put a more secure mount for the interposing relay for the starter and used a FET instead of mechanical relay, turned the radiator fan upside down to get the connector up out of the dirt, rewired the tail lights, redid my steering circuitry and strain gauge sand other stuff I can't remember at this moment.

Things are going well, hoping for good weather around Hanksville so Lenny and I can get it checked out. Googling it has it looking like some good area, on both sides of the road.

Finally got all the valve shims in, had to grind 2 of them on my neighbor's stationary belt sander, hope it's close enough to work good. One of the things I did was before I put the timing belt on, I ran the starter until the oil pressure came up, the I put the belt on and got it all buttoned up, minus radiator and hit the key and instant start. WOOOOO whoo!!!! No Smoke, just smooth running, and I hadn't even hooked up the throttle cable. Shut it down and finished put every thing back on and it started first hit every time. Photo shoot tomorrow of how I wired it and how fixed the swing arm.

Now to load it on the trailer and go find Lenny south of Hanksville.

PS. I plan to open the top up and retorque the head bolts and see if my valve clearances changed after I get back, and to have my feet operated on too.

      The conversion took about 350lbs. off the vehicle.  It never rode great, but now I feel every  crack in the road.  I have backed off spring compression nut to the point just under where they would move around if suspension was at full extension, but it is still very stiff.  I would like to put some softer coilover springs on it, but I have no idea what the spring rate is with the original springs so I would just be guessing on what to order.  Does anyone have the data for the original spring compression rate?  I am willing to give up a little ground clearance for a softer ride. Right now when sitting still the rear suspension is at or near full extension and the rear tires have several degrees of camber which will cause uneven wear if allowed to continue in this state.

      **Disclaimer: Yes, I know Polaris and Kawasaki are SOOO much more better, reliable, retain their value, not made in China, etc. I need a UTV and don't have the money or financing for one of those units, so let's keep this discussion productive please**
      Hi all, learning about my new T-Boss 760 from TSC, and am trying to find the actual dip stick to check the oil, funnily enough.
      Does anyone have a picture of it or something? It's crazy that I can't find it...yet here I am.
      Also - any advice on oil? Manual says 15W/40 "SJ" but I'm told the SJ spec doesn't exist anymore.
      Gentleman at TSC said to use any 15W/40, but I'm very nervous about causing an issue this early on by using the wrong oil.
      Anyone have advice?
      Thanks!

      Hi everybody. I just bought a 2012 Hisun with the 700cc engine. Was wondering where i could find a service manual for this thing?
      Its going to need some parts that are missing, like the air intake hoses and other things. Also the dash display is out. the only light that works is neutral light. Not even sure on the model. from pics I've seen, it looks like an HS700. Kind of grey with the black stripes on the hood. Just hoping i can find parts for it.
      Thank you for any advice you can give me. By the way, it does run and goes forward and reverse.

      I wouldn't say that after a year of owning this thing, that I would go out and buy one again. Certainly one that was used and abused, but at the time I needed something and this was in my price range. I could tell that it would need some work. I however didn't know the half of it. This was my second UTV. The first one was and older American Sportsworks Carbide 7150 that was a total piece of junk. I got it for next to nothing and was a project piece. I got it running and rode it for a bit but it was way not what i needed and it finally burned up and was set aside. Anyways, so I bought this one from a farmer. I'm not positive of the exact model but it originally came from Tractor Supply. per the stickers on the bed and its a camo color. Upon first inspection when I got it home, it was a mess.
      1. Had a water leak - The leak was in two hoses one of which was a short one that came from the rear of the engine and I literally ended up cutting it off. Well getting another one on there took hours and was simply horrible.
      2. Had an oil leak - This is my concern today as I was never able to figure out for sure what it was going to take to fix it. More on that in a min once you have a full account of where i've been in this thing.
      3. Had a bad clutch - Replacing the entirety of the clutch system wasn't all that bad except its a tight space to work in to do this repair. was a pain to figure out the angle that I needed to get the cover off and then back on again but figured it out the second day and got it done.
      4. Had bad Universal Joints - this was a nightmare because they originally put 18mm ujoints in the thing which I was not aware of so when my parts came in of course I had the 20mm that they started putting in, from what I can understand, was the very next year. Finding the 18mm ones was all but impossible so I bit the bullet and did the full conversion to the 20's.
      5. Had bad Tie Rods.  - Tie rods were not a problem. However while in there I noticed that it was a little low on brake fluid. The fluid that was in there looked fresh. Sure enough there was a line leak there so i had to get new lines for it. I almost just ordered the master cylinder at that time but had seen the  fluid coming from the other end and thought yeah it should  be ok. That was a stupid decision. Yet another parts order to get one. Once delivered it was not a prob just replace, fill, bleed and good to go.
      6. This was about the time the panic set in. I needed to check the other oils and the final gear oil was mostly empty and what was in there I'm still not was sure was gear lube. Luckily after clearing it out and refilling it, there didn't seem to be any issues with the final gear. So far that is.
      7. So at this point I figured that it was ready for my first trek with it to the  gold claim and off  we went. This was a 14 day venture in the middle of nowhere over 300 miles from home. I had tested it over the course of 5 days and except for the oil leak it looked like all was good with the exception of blowing a little smoke. Day two in the sticks it decided to just die on us out of the blue. I checked the spark and it wasn't there anymore. The plug wire had come apart. I made one that worked until I could get a replacement. It still wouldn't start but I was getting spark. ended having to remove the fuel pump and clean it up. I then had to pull the fuel injector. I don't know why it ran when it did. It took over 4 hours of running brake parts cleaner and air through it before I could get any fuel to go through it. Luckily after that most of a day delay, I'm glad to report that it did its job rather nicely for the remainder of the trip.
      8. After that ordeal and in the neighborhood of about $800 or so for parts and oils and all it looked a little brighter. I did still have not only the oil leak to fix, it started blowing more and more smoke. I keep the oil up but it uses quite a bit. if used in a whole day I'm adding at least a half quart. Its made three trips now in this described state. The only new things are that it has gotten very difficult to shift which is likely that pair of shifting gears, the blowing of smoke that is almost for sure a sign that I have to rebuild the top end including the top end kit and do the valves at the same time. Now the oil leak. 
      So this leak I don't quite know the part names but it is coming out from around the shaft coming from the front of the engine. My diagram does not seem to show that there is a bearing in there but I would think there has to be. So I can't order a part that doesn't seem to exist. Now the part I still can't figure out is am I going to have to pull the motor and split the case to do this repair or with the four bolts in the housing will this pop out into my hand and be a simple replacement? Of course after removing that shaft which of its own was no fun because of the requirement of almost having to remove the entire differential to get it out.
      Sorry for the lengthy story but I think that it shows some of the pain of these things. I grew up riding dirt bikes, motorcycles, and three and four wheelers and I can say that none of them were ever as difficult to fix stuff as this Massimo is. Heck have done motorcycles from the frame up with modifications and it wasn't this difficult. Let me  qualify that statement, I'm speaking of Kawasaki, Honda, and Suzuki motorcycles only once did ever work on a Harley and thinking about it that was horrific as well.
       
      Thanks for any words of wisdom besides junk this crap for a 17k to 30k upgrade. Only cause I'm 5'9 and my wife of 40 plus years is 6'1 and told me that i can't have the Kawasaki Teryx 1000 that I drool over. Getting old has really curbed her desire to deal with my toys over these four decades....
      Thanks for listening I look forward to and replies... Jerry

      I have a 2022 500 Hisun product, I have had them in the past. I change my oil myself and trying to drain through the hole where I remove the plug is a mess.  How does everyone keep the belly pan clean during the oil and filter service?
