T-boss 410

You're better off to let the technician do the repairs if it's still under warranty. But I do know that with automotive oil pumps (at least in some Mopar oil pumps), the oil pressure is set by a spring inside the pump body,and can be changed to push up the pressure or lower it, whichever you may need. That's why I was curious about the spring inside this pump. Just something to keep in mind if needed.

I wonder if there is a way to modify the oil pump to increase the pressure? Maybe a stiffer compression spring, and/or a heavier weight oil?

That's too bad. You'll have to do without until then? I know very little about these UTV's,but if it were me I would start researching oil pumps. Might find the issue has been experienced by another owner.

Yeah, sounds like an oil pump issue. Your buddy hasn't looked at it yet?

I will do that, sir!

Hmmm...didn't know they offered a code reader, but I would think that the diagram provided by Joe Toup would be a much less expensive option, especially if you already own a code reader. I will have to check closer on that. Do you have any idea where the port is located?

I wonder if there is a flashing code with the CEL, or is it just a light that comes on? I guess the tech has a service manual and access to the manufacturer for any repairs. The older vehicles would flash a sequence, which could be interpreted using the manual or the internet to investigate what the code was for. Heck, there may be a port somewhere on the machine, but without a service manual I wouldn't know. That $75.00 fee is a bit steep for me, but if I can't locate one somewhere else, I will have to bite the bullet. These machines do have an on board computer of sorts, don't they?

Yeah, it would be great if an owner could monitor what's going on with the unit. I have no idea what to do if, God forbid, I get a CEL. With my vehicles, I can just plug in the Bluedriver and check the codes. It will tell me what the code means, and even suggest some fixes. I don't know if there's even a port to plug in to. I try to do all the repairs and maintenance on my vehicles myself, but without any way to diagnose the issues, I have to use this site or bug the tech at Massimo for info. Kinda makes me feel odd, not having the ability to do things myself.

So, this is not an electric gauge? Is there a way to connect an electric gauge instead of the manual one? Any idea where the location to install one on a Linhai engine? I'm all for preventative care, especially since I have a lot of money in this unit and I would like to keep it for a while. Thanks!!!

Do these units monitor the oil pressure? If so, how? I would be interested in that information.

I believe that the OP has already, and I have contacted him as well. He's trying to get a manual that's specific to my model. Until then, I need to continue to utilize this forum for assistance, and at times be able to offer some advice and assistance to others.

That's why I inquired about the heat indicator, whether it is a gauge or light, or an LED dash such as mine is equipped. I was just trying to eliminate the overheating issue. But if the tech at Massimo suggests that it could possibly be a fuel delivery issue, I would think they know best. But it seems to me that it's a little soon for a fuel delivery system problem. Is there an indicator of some sort for low oil pressure?

Thank you, sir. If you think you will have it soon, I can wait.

Yeah, I know what you mean. I don't have a trailer, either. Been looking for one, but either they are asking too much, or it's a hunk of junk. At least your buddy can fix it for you.

How far away is the nearest service center?

Do you have a temperature gauge of some sort on the UTV? It would let you know if it's getting too hot.

Would you happen to carry a copy of the service manual for a T-boss 410? Thanks!!!

Is the engine overheating? Seems to be an issue, but mostly with the Hisun engines. Don't know what make of engine you have, but there are others here who have experienced the same problem. Sort of sounds like it is overheating under a load, such as when you climbing hills. Have you contacted Massimo yet?

May I ask which service manual you have? I just purchased a 2019 T-boss 410, but purchasing the service manual is a bit more than I want to spend without knowing what quality of a manual it is. Thanks!

Yeah, I'll do that. I have a section of the service manual that was forwarded by a Massimo tech. It's the electrical section. I had some questions about some electric gremlins that I thought I had, so he was good enough to forward that section. It was useful. He's been answering any questions I have, but eventually I'm sure he will advise me to go ahead and purchase the service manual. As you said, I don't want to drop that much cash on something that doesn't cover everything that I may need. I have a few Haynes manuals, and they cover most repairs, but definitely not everything.

I have an owner's manual downloaded. I am hesitant on spending the $75.00 for the service manual, though. Just seems a bit expensive, IMHO. I suppose I should just bite the bullet and spend the money. I was hoping that I could locate a copy elsewhere for a better price, but so far that hasn't been the case.

So...what is the procedure for clearing the codes?

I stand corrected! Turns out it was a sensor issue as you said earlier. I gotta say, there's way too many sensors in today's engines. I understand that those sensors are necessary for the fuel injection to operate, but I think that can be engineered out of the system. I know that it's dependent on the EPA and their rules and regulations, but a backyard mechanic could go crazy trying to diagnose these problems, unless you have the expense equipment needed to do that diagnosis. I like to fix things myself. It's satisfying for me, not to mention cheaper. You mentioned that the error codes are read through the clock? I have a digital instrument cluster. How would I read those codes?

How do you do the trouble code tests? It would be good to know for future reference. Thanks

I had a similar problem with a vehicle. Exhibited the same symptoms. Ignition coil was bad. It ran fine just cruising in low rpms, but give it some throttle and it would bog down and begin to misfire. To me it sounds like a fuel delivery or ignition system problem. But I don't have much experience with powersports engines.
