One option for CVT filter on a Z8
« on: November 12, 2016, 08:14:13 PM »
                                                                                       One filter option for the CVT
I decided to mount a CVT filter in the bed but needed to plumb to it. This is how I did mine.
First, you will need:

2-3” silicone 90s. I bought two of these.
http://www.ebay.com/itm/281952541871?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Two connectors. One to join the two 90s and one to serve as a mount for the filter. I bought these.

One piece of 1/8” black ABS to make the cover blank out of. I bought this one but a smaller one would be better.
https://www.amazon.com/gp/product/B0007WTF02/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

And you will need 4 clamps that will fit 3” pipe.

For my application, I needed to place a 6” filter at the far left side of the bed so I needed the center to be about 3.25” from side of the bed. If I was going to just place a tight 90 on the port and go up with a snorkel with a filter on top, I would have a little more room and wouldn’t have to cut all this so short. You decide what you want first. This “How To” will be for my application.

First dissemble and put the CVT intake tube where you can make your first cut. Cut it so there is about 2-times the thickness of the clamp left on the bottom. The cut will be about here:



The two 90s will need to be cut down to their minimum. This will be so there is just enough room left for the clamps. Be sure to maintain the 90’s end cuts. Then you will need to cut about 1/3rd off the aluminum connector as the 90s are now very short. Put it all together and it will look like this







Leave it a little loose and slip it back into place. Rotate the fittings to position it. Make sure the end 90 sets flat against the bed plastics and the tube is in the CVT boot on the engine..and the hanger pin is installed. It will look something like this.




You will notice that the 3” pipe is making contact with the inner plastic so once everything is positioned carefully remove the system again, tighten all clamps well. Then going by the angle mark on the back side of the CVT pipe, compress the connector in a vice or clamp into an oval making the top slightly tighter then the bottom. Check the fit and if necessary re-adjust. This view shows the flat angle mark on the pipe next to the 90.



Reinstall it completely and check that it is in a relaxed state and laying flat against the bed plastics. Then draw around the 90 against the bed to mark where the hole should be. Remove the system again. Then with your 3” hole saw only, slip it behind the plastic, line up the teeth to the marks and rotate to make a mark with the center bit. Then with a small drill bit, drill through the mark so you know where to center the hole saw on the bed side. Drill your hole. Yes, now you are committed! You have hole!





Clean up the hole so the PVC connector fits easily. Reinstall the system and insert the PVC connector through into the 90 and clamp well. And install your filter. I’m just going with my 6” mushroom with the Unifilter and outerwears prefilter for now. Should look something like this.









Now to seal-off the old access. Using the old door as a template, trace it out on your ABS sheet to include the legs and an extra long tab to fill in where the lock was. Cut out then file, grind or sand as needed to fit all the way down. Heat up the long tab and custom fit it to the lock hole. This will take some time as it has an odd angle and bends. Then using the screws and screw holes that the old boot used, drill and mount the blank. Then with RTV, seal off on the back side.
It will look something like this.









Complete reassembly

That’s it.  Good luck with yours.

UPDATE 11/21/16:

Can't leave well enough alone. Upgraded the filter to a coned gauze filter like the intake...except slightly smaller. Better and longer consistent flow and although like the engine's intake, both are dry-type I am using fabric-filter spray oil on both for the best filtration possible. I will continue to use the red outerwears water resistant prefilter only because it fits...and I have two thanks to Jogon30 for giving me his after he traded in his Z. Some pics:









UPDATE: 6/17/17

After finally putting this to the test for a week in very dusty conditions I can safely say: I still believe that the reduction of dirt and dust through the CVT system has positive effects on consistent performance and reduction on wear, however this location may not be the best location for the intake and filter as it only took about 30 miles of dusty roads to reduce airflow through the filter causing CVT temps to increase. The actual intake either needs to be higher...or more forward to get enough time between filter cleanings. I was thankful of two things on this ride. One- that I installed a CVT temp gage that told me when the air flow was down and temps were climbing before loosing a belt and Two- that I installed a dry-type filter that could just be popped-off, tapped out on a rock and reinstalled. The amount of dirt and dust it stopped was nothing short of amazing. I would guess in all three cleanings somewhere about a 1/4 of a one gallon paint can of dust was captured between the filter and what was on top of the prefilter. But..the location in the bed is in heavy dust all the time and would have been less if it were somewhere else. The engine air's intake first filter was also packed full but it didn't effect it's running. It may be snorkel-time just to get the intakes out of the main dust cloud.

Have not had it out yet.. but before I started the pipe disassembly I fired it up and placed my hand in front of the CVT exhaust just to get an idea of flow. Did it after it was all done and there is much more flow coming out the CVT exhaust with this filter over the surface filter I had before...and both were clean so I'm looking forward to more and clean air...and a longer time between filter cleanings. I have two extra filters oiled up and in a zip-loc bag for it when and if needed. Overall I would think that should lead to a cooler CVT. One other thing I noticed was...and it might be my imagination...but not having that intake port right behind my seat I think the cam is a little quieter without that CVT noise. I did put my silencer on the muffler so that might also be effecting my judgment.

Today I discovered a couple of interesting things. I decided to check the filters after two solo desert runs to see how much dirt they picked up to judge how long I could go between cleanings. The first thing I noticed was that the CVT pleated gauze filter had more then twice the amount of dirt in it as the engine's first filter. As they are both fairly close in the same location I have to assume that overall, over the 50 test miles, more total air must be going through the CVT then the engine. Does make sense... Although it hadn't started to become restricted, it does show I certainly don't want any smaller filter on the CVT.

The other thing I noticed is that even with these dry-type micro cotton filters being oiled, there was still trace amounts of dirt on the intake tubes. See, I rub a little filter oil inside the tubes so I can swab it and see if anything gets through. There was some..not much..but some. So I took a good look at the CVT filter...and found that it has 5 pleats that didn't get sealed with the glue to the base and they had good sized gaps. Holding it to the sun helped me find these. I sealed them with black RTV but If I ever see any more trace in the tubes, I will be sh*t-canning these cheap filters and going back to a foam..or a better quality pleated cotton filter. I have not looked at the big primary engine filter for gluing problems...but there is trace amounts of dirt in that intake tube too. Good thing I have a Uni in the box...lol   

So if any of you are using these filters, take a close look.

Maybe this is just me but I REALLY dont understand the need for the (IMO) "Over filtering" of the CVT???  CF Moto is one of the very few that even has a filter on them and the others they just let the dust blow through.  There is no grease in there to catch the dirt (on other SxS's I have run grease with UN FILTERED air going right through with no wear and would service it every thousand miles or so) and filtering it only slows the dust down and DOESNT let it blow out the back side.  On top of that it adds to the heat build up because it slows the air down even more and will likely kill a belt faster.  Im just looking for a major benefit to going through all these steps and fighting a battle that has not been a problem on all other SxS's manufactured.
I can imagine a world completely at peace.  A world where there are no weapons, no war, and no violence at all.  And I can imagine us taking over that world because they would never expect it.

Well, if you saw what Jogon30 and I have on what our sand and dust does to our CVTs, you would want something on the intake side too. But..it looks like keeping the airflow up is with the volume that gets pumped through it for a decent length of time is going to be a challenge...lol  I may have to settle for keeping the big stuff out only by not oiling the filter..which is what many others with filters do.

I know what your saying and agree that if it was possible to filter it then why the heck wouldnt you right?  But belt temps are always an issue when running in warm climates and running hard and fast.  You throw a filter or 2 on it and slow down an already passively cooled belt (no forced air) I think the benefits of the filter get eaten up by the draw backs of the heat.

Is the issue with you guys and the sand that its keeping sand in the CVT housing and pitting up the sheave faces?

As an FYI I ordered these 2 parts -

With the gauge I will know EXACTLY what my CVT temp will be at.  We are racing so if I need to drive a bit more conservative to let the temp come down then I can.  But I am going to wire the blower to a switch that will pretty much remain on all the time.  I want FORCED air hammering through there as much as I can get it.

This.  I've run several CVT machines, and I don't think I've filtered any of them.  In fact, I removed the screen set up on one, and went with a scotch pad which allowed much more airflow and had good results.

Not so much the sheave faces although there was some sign of slight wear along with the belt. It's more the sand and other abrasive partials gets in the slider tracks and as they slide back and forth, they grind the sliders and the aluminum tracks along with the sand into a fine flower-like dust that packs on either end of the slider/roller track. This not only reduces the movement but in time wastes the slider and eventually the track it slides in making clutch replacement the only option in the future. Although I didn't measure my sliders when I installed them I did check their weight and adjusted then all to be 22.04 grams. On the last cleaning before I started filtering they averaged 21.08 grams so...they are loosing at least some material. You also see what that does to the secondary helix ramps and pads. I can say sense I started keeping the majority of the trash out, I don't see any more wear, or have any more powder buildup and my secondary helix ramps and pads are keeping the polish I put on them and wear seems to have all but stopped. And for me and my riding, I am not having any heat issues.. so for my application, there is benefit. For you and how you have to push yours, yeah..you probably need to watch the heat and get as much air as possible.

Yeah I didnt want you to take it as "your doing it all wrong".  I just dont see a need for it with my riding conditions and style.  We have small patches of ground around here that we call "sand" but its more like tiny rocks that dont get air born very easy.

Oh it's F'ed up here. No moisture..no rain...riding in solid clouds of dust and sand everywhere...even in the mountains from mid summer on. You have to wear a face mask all the time. Hell, the exhaust guard the CVT discharge points at looks sand blasted...lol

Do you ride at Badlands much?  We've been there a few times.  Nice place to ride, little bit of everything there.

I have been there but dont normally ride there.  I have 90 acres I ride on and friends land.  I travel a fair amount usually to ride also (WV, Michigan and so on) but this year we are racing MWXC series so that will consume a lot of my time.

It's not just the desert that tears these up. When it gets dry the dust here in MN is enough to pack the primary so full that it just doesn't work right. The secondary on mine was bad off and had to replace the helix and buttons.
