Hello 

I have a 2022 Massimo t-boss 550. I’m looking for a fix for my timing problem. It keeps getting out of timing. Now I’m trying to find the proper parts for the linhai motor. I’m looking for tensioner chain and gear. If there’s anything else I can do to fix this issue please let me know. Unfortunately I can’t afford to get something better so I got to get it fixed. Thanks in advance.

If it's jumping timing likely the chain is stretched. Usually thats more a a function of wear on the pins from poor oil lubrication. Excessive metal in the oil, etc. It could just be poor metalurgy/manufacturing on the chain too.

The hisun equivalent uses the same chain as the Yamaha Rhino 660. They actually even accidentally use the Yamaha P/N in the service manual. There are a ton of these available sub $20 on amazon/ebay etc. Any chance that the motor uses the same chain? Can you send a pic and count the links? I'm assuming the motor may also be a Yamaha knockoff like Hisun.

Also you'll probably have more luck in the model specific forum.

Well what can I say somebody has to bye them! Lol

but again thanks for the advice , I’ve got it going and seems to be working pretty good so far. I added weights to the clutch and it seems to be a little better for what I use it for. By the way it was the chain that was finished that was the major problem. Although these Utv are made cheap and I had to learn the hard way.  Now that I know what not to do with it. The Massimo t-boss 550 might last me a little longer before I need to do more repairs to it! lol 

have yourself a great day and thanks again!

      As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault!  I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

      Belt started slipping when I used it in high gear. It works okay in low unless I'm trying to power it up a hill and then it slips.., Ordered a new belt and went to change it and found a good bit of oil in the belt housing. Has anyone experienced this? Belt looks fine. Only have 300 miles on this thing..

      Does anyone have any suggestions for aftermarket shocks.  I have a T-Boss 550 and took it riding in some rough trails and the stock suspension was uncomfortably rough.
      Thanks

      I have owned mine for a couple years now but newer took off road.  How well does it do trail riding m?

      I've had a Hisun Vector E1 for just a bit longer than is required for me to do some maintenance. While it's well-overdue, it only drives 1.5km a few times each week on a fairly decent gravel road (to the letterbox), and it has worked really well right from the get-go.
      Looking at the manual it states that I need to use SAE80 API GL-4 Hypoid Gear Oil for the Main gear Case, and SAE80 API GL-5 Hypoid Gear Oil for the Front gear Case - unfortunately i can't find either of those online here in Australia. Plenty of options that look close, but, as someone who has never driven any vehicle before, I want to use the right thing and it's a tad confusing.
      My question: Since there are no oils that are bang on SAE80 (they all seem to cover a range) would Liqui Moly Hypoid GL4 Gear Oil 80W-90  & Motorex Hypoid GL-5 Gear Oil 80W90 - be ok to use? (Or any other suggestions of what I might be able to purchase online in Australia) And would I have to drain out any existing oil from both gear cases?
      This is a whole new world for me and  being able to find exactly what is specified in the manual hasn't made this easy!
