I guess I'll hold off then. I thought it was a ridiculous price, but I would have bit the bullet if it was useful. I enjoy doing my own repairs on my vehicles, and I don't know how I would find any useful information if and when I need it, but I would prefer to avoid the frustration of having an expensive service manual that won't offer any real help.

So, are you saying that it would be a waste of money to purchase the service manual?

OK, thanks. I don't know what the O ring composition is. I only have seen it in a parts diagram. As for the pic, I can only hope it won't take that kind of torque to get the plug out 😕

Very good, sir. Thanks!

What about the O ring? Does it need to be replaced at each oil change? I have a rather large collection of O rings, but I don't know if I have any large enough.

Thanks for the tip! Is the plug aluminum, as well? What size is the o ring?

Lol. I know what you mean. I do a lot of work on my own vehicles, and can't remember the last time I did any work without getting beat up in some manner. Just changed the spark plugs in my Ram yesterday, and I have the cuts and bruises to prove it. I admit I do let go with some choice language, but it's a stress reliever, if you know what I mean.

Lol, thanks. Had me scared for a minute there. But, I have read a few posts where the complaint was that the drain plug was so tight it couldn't be removed. You didn't have that problem?

Sounds like you've got it pretty much narrowed down. If I were you, I'd get the oil changed as quickly as possible. If for nothing else than my own piece of mind.

3/4 inch drive? Holy crap!!! I don't own a drive that big. My biggest is 1/2 inch drive. Why is the darn thing so tight, anyway?

I apologize for being off topic, but I am getting the idea that removing the oil drain plug is a very difficult task. How have some of you got it broken free?

As far as the tech goes, your feelings may be a bit of both. I don't know for sure, but I don't believe there are a lot of certified Massimo service centers around, so he's probably getting more business than if he were working on other makes. The gas in the oil thing is concerning. Maybe their attempt to spread out their supply of break in oil, or something else that they know about during the break in period that they don't let the buyer in on. I wonder where you can purchase oil that not only meets the viscosity that the factory calls for, but is also good for wet clutches?

Unfortunately, he's correct. Unless you have a friendly relationship with the tech, it's likely to be an uphill battle. You could get with Joe Breaux here. He's worked through some issues with his Massimo, having been denied service from both the seller and the company. It's not the same issue that you're dealing with, but he has a tech that has done the work on his unit, and Joe has been very helpful here.

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?
