What's the purpose of a case saver?

[Dimpy3]

So I have a 350x I hear a lot of talk about case savers. I don't even know if my 350x has one or what they do? I just wanna know what the purpose of them are. I would like more of an answer than they save cases..
I'm new and this is probably a dumb question...

[rjs89ia]

if and when you break a chain or throw one its supposed to prevent it from chewing a hole in the case.

They are there to proect the cases right in front of the front sprocket. It sucks when you dont have them there and put a stone through your case! Believe me I speak from experience! Just now replacing the side cover and repairing the case after doing this at trikefest. If it happens to you be prepared to spend about $500 to fix it complete correct, or at least $200 to do it the way I am. Spend the the $30 and put one on if you dont have one already: http://www.ebay.com/itm/ATC-case-saver-for-Honda-350x-three-wheeler-/190739516778?pt=Motors_ATV_Parts_Accessories&hash=item2c68f60d6a&vxp=mtr It is also available in our store: http://shop.3wheelerworld.com/productdetails.php?productid=48
This is made by a member on here, and I have one going on my machine tonight.

To determine if you machine has one, take off the sprocket cover, and see if there is something that looks like what I posted above is in there, if it isnt, order one.

I've gotta get one for my 250SX.

That one goes on the right side!!!!!!!!!!

[Big Mike]

LOL Fabio!!!

Ok that was a joke about the 250sx being a shaft drive . . . But yea it is very Imporntant I had to replace my casing because my brother removed the case saver and instead or tightening the chain a little being in a rush rode doubles and had the chain jump and destroy the case . . A huge mess instead of just straightening the saver. A little and tightening the chain properly. . But never the less cost me 200 for a set of cases and the down time to do the repair plus gaskets plus not talking to my bro for a month and also him breaking up with the girlfriend over me and him fighting cause she was the one that rushed him in to riding it instead of fixing it properly . . So lesson is a case saver will save u a lot of aggravation and money but maybe can b good in some cases cause that girl was a trailprotrailprotrailprotrailprotrailpro and had to go but still I'd rather had kept the money

Haha story of my life...

We have a case saver on the front and rear of my gf's 87 250sx.


I still need one for my 86 250r, it has one of the holes for the case saver mount jacked up from the chain jumping. Cases are expensive

[sp8twn]

It's a MUST!! that what it is!!:lol:

They protect the cases on a Honda which will inevitably habitually throw the chain into the poorly designed clutch shaft that sticks out in its path. A swingarm chain guide is money equally well spent, but having both is the best insurance.

On a Yamaha they serve no functional purpose, but they look pretty, and buying them helps out those who make and sell them.

Why do they serve no purpose on a Yamaha?

Here is my repair to my case from this week after the carnage @ Trikefest

Well, I can tell you if your case doesn't break on the Z....It's gonna look like TrailPro by the time you come to a dragging holt. IMO it's a bit of insurance to contain the wad of chain ripping toward your motor at case snapping speed.

^^^^ JB saves another...send them a pic, might get a free tube!^^^^

[Big Mike]

All fixed.

[fabiodriven]

Hey that looks good Mike! JB Weld?

[Big Mike]

It is Putty Weld, made by JB Weld, so much easier to work with in this instance that regular JB weld would have been. Thanks Fabio, Fixed the case and replaced the outer cover. Case Saver and cool Sprocket Cover that I won at T'Fest go on tonight.

i must respectfully disagree with you sir, and if need be can produce photographic evidence of a quite damaged tri z engine case shens

[ps2fixer]

Have to support the idea of a case saver, never knew there was even such a thing till I bought a parts engine for my 250x, oh boy did I need one for my 99 Yamaha Warrior... it has a crap rtv repair on it to keep from leaking, but it don't run atm anyway lol.

[TimSr]

I'll back off from the "Yamaha" claim which was too general, as I really can't speak for the thumpers and some of the quads. I'm mainly talking about the TriZ, Banshee, and Blaster which use the same type chain guide system.

First, I had a TRX250R for 4 years, and can't tell you how many times I threw the chain. Jr has had his 86 ATC250R about 5 years, with multiple chains being thrown, and one case weld job, after twice doing damage WITH a case saver. I've been riding TriZ's since 1990 in some of the worst conditions known to man. Number of chains thrown in 22 years is 1 if you count the time I lost a master link. Thats a lifteime for many of you! My brother has run his banshees since the first model came out in 1987, in even worse conditions than me. Number of chains tossed since 1987 = 0. He has run a Blaster since 1993 which Jr owns today. Number of chains tossed on this Blaster since 1993 = 0. My first objective was not, "how do I protect the case", but rather,"how do I keep this stupid Honda from throwing chains". Case savers are nice on your Honda, but a Yamaha style chain guide is better insurance.

Now lets look at what happens when you do throw a chain on a Honda. The clutch pivot shaft sticks way out about an inch or so directly covering the entire patch of the chain as though it were placed there just for catching and wadding tossed chains, which it always does.

Then look at your TriZ where the clutch pivot shaft is barely in the path of the inner side plates of the chain, which deflects the chain to the side of it if you have the extremely rare misfortune to actually throw one. If you add a case saver, you actually increase your risk by creating a surface for your chain to catch on, and wad up inside of, and crack the case where the case saver is counted. But as I said, that risk is minimal since its extremely rare to toss a chain to begin with. I do however recommend removing that plastic front spocket guard if you have one, which also serves as a wad up guide.

I do have some TriZ cases with what looks like chain damage which amounts to grooves in them. I have doubts as to whether its from thrown chains, or it was just a chain carrying mud and acting like a belt sander. Maybe a case saver could help in that respect. I guess everyone should use their best judgement for their own situation, and I hope you get the results that I have.
