Where is Teryx4 Engine Brake Located?

Coming from an older machine, just got this 2016 Teryx4 800.

I have the tank out, all plastics from the front half and seats.

Where is the engine brake module/motor located, or the wiring pigtail?

Thanks

Completely new system compared to the electric system on the Brute Force and first Gen, Teryx. Engine braking is provided by a sprag, or one-way clutch between the crankshaft and the primary CVT clutch, all mechanical.

Is it located in the housing if I remove the clutches and belt? Or is engine disassembly required?

If someone could give me a diagram that shows this part i'd appreciate it. Probably would help others too.

Pretty sure this is what's causing mine to bog down at slow cruising speeds and then jump back full power. No electrical issues at all on this machine. It's funny because since I've removed the clutch housing cover, I can drive all day at light throttle maybe 20mph steady and it won't bog down anymore and randomly jump back to full power. One thread on here goes on and on and the guy said he sold it because he couldn't figure theproblem out but mine is identical.. everyone was pointing to TPS and fuel.. not the problem here.

It is inside the cover behind the CVT clutches. You should be able to access a digital manual somewhere here on the forum, year won't matter the engine brake system is the same on all years of the Teryx4 and the Teryx2 from 2014 to present.

As was previously said, get the manual. Plenty of them around. BUT, also go to a parts vendor and look at the drawings and parts layout. I happened to go to Rockymountainatvmc.com and looked at OEM parts for a 2016 Kawasaki Teryx4. I looked at the drive Converter and the Driven converter, expecting to find the same type setup up as on my Polaris RZR. But I also went to the clutch schematic and found item # 13194 which is a Clutch-Oneway. Kawasaki Part # is 13194-0555. It list for $92.38 but sells for $71.13.

This is a new concept to me having the older Brute Force electronically controlled brake fork with a shoe that rides on the clutch and slows the vehicle down. My Polaris RZR does not have any engine or electric brake unit because it is the base unit. I can upgrade the clutch and have it put in, but I am happy with the way it works.

I will look further into this. I looked at You Tube and did not find anything relevant to this. Todd at HunterWrrks is a good source of information on CLUTCHES. V Force John is a good source of info for Kawasaki clutches and does a lot of different upgrade with our clutches...

Good Luck...

The oneway or sprag clutch is between the crankshaft and centrifugal clutch inboard of the CVT primary. The oneway clutch provides the engine braking effect when the primary clutch is trying to turn faster than the crankshaft, as in rolling down a hill at idle.

Looked a little more. Found an exploded view in the Manual. Also found a test for the one way clutch assembly. It appears to me, sitting in front of a computer screen, not in front of a Teryx, that if the belt were off and the drive (primary, front) was turned Counter Clockwise, it should turn free. If turned Clockwise, it should not turn free. It might answer your question as to weather the clutch one-way assembly is good. Might need to turn in at different speeds to simulate different engine speeds.

It appears that changing this One Way Clutch will involve a pretty serious disassembly of the machine...

Good Luck...

In the Manual, it's chapter 6, the Converter...

I would recommend doing some more research on how this system works before digging into it. The reason I say that is I'm really not sure this mechanism is even capable of causing the issues you are reporting. I could understand on an actual electric actuated brake system it could be periodically engagaging and dragging, but on a mechanical one way clutch that is using engine compression forces to slow it down I don't understand how it could cause the issues you are describing?
