Couple more questions. By skytex (Read 2,564 times)

Ok first, what is the importance of the gasket on the cvt/cover? Mine tore when I pulled my cover off. Should I order a replacement or just use some forma gasket?

If my chain is jumping teeth, how can I tell?

Is there a way without an impact or expensive tool to get the clutch out?

I'm a fat guy. 350lbs. I want more top end. It's only going about 50 now. I plan to get the taller tires. Should I change the variator/clutch? If so I think I'll do a dr pulley variator. What weights should I run? Would it be cheaper or as effective to put new weights in the old variator or just get the whole new system?

How do I tell my engine rpm?

Lastly rather than all this, anyone wanna trade a running magnum for a yamaha 4x4 atv?

Q1. Gasket is NOT important, if you notice the Cvt cover fits nice and snuge up against the case. I ripped mine off 2 years ago.
Q2. Chain Jumping Teeth?
I do not think the noise your hearing is the CHAIN. Look straight from the REAR SPROCKET TO THE FRONT SPROCKET, if the Rear Axle is out of LINE the chain will NOT LOOK STRAIGHT. You will be able to tell if the chain is out of wack.

But the reason your asking about the chain jumping teeth,
I AM GUESSING that when your starting OFF it is JUMPING ON YOU
(IS THAT CORRECT)?

Q3. Removing the CLUTCH without something to hold the BELL is difficult at best. But you may also need a IMPACT WRENCH. Either that or Get some help and get something to HOLD THE BELL while another guy puts a wrench on the NUT and A EXTENSION to get some Leverage on the NUT.

Q4. Yes, the trikes will only do about 50 out of the Crate. I suggest putting in Taller Gears 15/38 are good for 8-10mph top end speed gains.
You can go with a Performance Variator which is 115mm in diameter same as your Variator Fan, that will give you about 3/8 inch more travel on the belt for more top end. The One I have is the Prodigy Variator which is 115mm in diameter and my belt climbs up to 1/8 from the edge.

Weights I run with 12G Dr. Pulley Sliders, I have tried rollers from 10grams up to 13 grams as well as mixed them. I have tried Dr. Pulley Sliders from 11G to 13 Gram and mixed them. For my rideing I choose the 12G Sliders but then again I only weigh 180lbs.
For your Weight you may need the 11 Grams to get more RPMS to pull you better for starting and getting up to speed.

You should get a TINEY Tach or something to mounter your RPMS. KNowing the RPMS the engine is running is very important it can tell you if your weights are to heavy or to light or some other problem with the way the engine is setup.

As always, your a priceless source of info! Hell, atleast I'm starting to throw around some of these terms with some degree of competence lol.

Yes your right. It's only on takeoff. At first I tried tightening the hubs, that didn't work. Now i've been in the process of trying to see if the bearing is missing, but I don't think that's it now. Not after trying to get the clutch out and hearing it pop while my head is down beside it. I'll still pull it off to look as I need to change the gear oil anyways while I'm down there. I'll pull that rear deck off this evening and look at that chain too.

Any recommendations on where to find those taller gears?

[Alleyoop]

Ok, Does your Trike have a REVERSE? If so it probably needs to be adjusted. It is not meshing with the forward gear.

If YOU DO NOT have reverse and your Axles are tight then it is NOT good news.
These motors they left out a Support Bearing on the Drive Shaft and it will flex and not mesh with the tranny gears and will eat them for lunch. The good thing it is an easy fix and you can do it yourself. All you have to do is Drain the Tranny Oil take the Clutch off and then unscrew the 5 bolts holding the Clutch Shaft plate and that is also where you change the Taller Gears as well.
Here is where the Support Bearing is missing:

And here is where I got my Taller Gears:

[skytex]

Yeah no reverse on mine. I was gonna pull the clutch to look for that bearing anyways. If I gotta dig in there for those gears anyway then I'll keep it torn down. Where would I buy the new gears?

[Alleyoop]

That missing Bearing is a C3 #6004 Deep Groove Radial Ball Bearing .

I think the gears that get bad IF the are bad are actually the ones you want to change for taller ones.
Alleyoop

[skytex]

Haha perfect.

[Alleyoop]

Yes such a deal(HAHA), just check the Case for any CRACKs around the Bearings you will be fine.

[skytex]

Ok oh mighty guru of trikes, no missing bearing. the chain has about a half inch of play. looks to be straight. you take a look and see what's missing.

First this is inside the gearbox after removing the gears. BTW the gears show 0 wear. no nicks no nothing. gear oil I drained was clean no metal shavings either.


This is the cover plate you had me remove to get into the gear box.


This is a close up of the final drive bearing. Is it really a bearing in there or just a spacer? If it's just a spacer then maybe I don't have the bearing after all. You judge.


A couple of the chain.

[Alleyoop]

Looks good my man, the Missing bearing would be the one on the top left in the first picture.
The chain looks good and straight as well, So your good to go with TALLER GEARS(HEHE).
Left me ask something and you can check your Axle TUBE. Does yours have the following Two Screws about 6 inchs from each end of the Axle TUBE like the following.
Alleyoop

[skytex]

No alley. The only bolt going into the axle tube is the one going directly up from the bottom of the fender mount.. I believe it can be seen in your picture as the bottom left bolt bearly in the picture. No holes there either where one may have rattled out.

[Alleyoop]

BUMMER, What year is your Trike supposed to be, is it an Early 2009?
You see that bolt in the TUBE, well there is another on the other side of the Tube.

Those screws screw into a FLOATING RING inside the Tube. What they did Later in 2009 models was weld a piece of pipe about 1/8 thick ONTO the AXLE itself and added the Floating Ring. The purpose was to STOP the Axles from moveing out. The 1/8 Thick pipe welded onto the axle hits the Floating Ring and Stops the axle from moveing out any further.
If yours do not have the Floating Ring then the only thing stopping the Axles from coming out is the "C" Clip on the Outside of the Bearing on each end.

If the wheels get loose the SPLINES on the HUB get damaged and Skip and Jump on the Spline on the Alxe Splines, they do not grab. So when that happens your wheel will wobble or move up and down on the Axle itself and make a not so good of a noise.
You can take the Hub and Wheel off and hit the end of the axle some taps and see if it will go in some. Inside the Differential are Spider gears that have a sleeve with a Built in Key. The axle has slots that fit onto the key inside the Spider gears sleeve. So if the axle move out some you may be able to tap it further onto the key to hold better.
Alleyoop

Here you can see the Two Screws on each end Holding the Floating Ring.


And here is what it looks like taken apart:

[skytex]

So the splines on the inside of the axle may be damaged? Ill have to wait until tomorrow to pull a wheel off. At this rate its kinda running out of options on what coukd be wrong.

As for the year, all i know for sure is its an 09. Anyplace i could look on it for an actual date made?

[Alleyoop]

It may say on the Metal plate when it was built, BUT if you do NOT have those screws on each end on the Axle TUBE then it is an EARLY Verison like mine. I complained right away to them and they sent me a UPGRADED axle with the Floating Rings, it took three months for them to send it to me but they did, A complete axle. For all I know I may have been the one to get them to upgrade it cause I told them that it was dangerous and someone could get killed.

The Splines on the AXLE would NOT BE DAMAGED the SPLINES in the HUB would be rounded off because the INSERT SPLINES are not made of HARDENED METAL. In that case you would need to order NEW HUBS.
Alleyoop

[royldoc]

That is what happened to mine. I don't think the splines are bad yet. I haven't had time to tear it apart and fix yet. The left wheel is wobbly I haven't determined if the bearing is bad also as the axle wobbles with the hub. I Will know when I get it apart. Hopefully the bearing company we use at work will have them and I wont have to order. Also instead of the floating ring I plan on using thrust bearings. If the axle and hub are bad I will have the shop make me some of better quality.
