1100 >>> Removed IT <<<<<

[TWO GUNS]

Well he got the problem resolve that was mentioned on another thread ...</P>


He found the spark arrestor inthe muffler of the new RTV 1100. And removed it . Attached will be a picture of the arrestor. Only has very few hours on it, and it's very clogged up and of course, we know it was choking down the machine. I would advise anyone, to keep a check on this, if not nothing else, remove the thing .... </P>


I don't see how the machine ever run . </P>

I've tried to down-size the picture some . Maybe we can see it better . Hope it comes out O.K. ~~~~

What were the symptoms that led to this discovery? How old was the machine when the problem ocurred?</P>

Re: 1100 &gt;&gt;&gt; Removed IT &lt;&lt;&lt;&lt;&lt;

Well , the machine is new !!!! Brand New !!!!</P>


During our conversation, he was telling me that how his unit was smoking going up the mountains. I made the remark that being his machine is smoking like it is, he need to check the arrestor to make sure it is not clogging up. He checked it, and you can see the rest. He's running tracks also...</P>

What would make it get clogged up so fast?

Have you ever seen that screen, it's way smaller mesh than a ladies pantie hose !!!!</P>

Diesels don't need them !!!</P>


Below is a quote from another source, that statement is very true !!!!!</P>


</P>


<FONT color=#ff0000 size=4>There is an elaborate testing process spark arrestors must go through to meet the USDA/federal requirements. You can't blame Kubota for this as they really have no say in the requirements. I can see where a spark arrestor for a diesel with it's exhaust particulate matter could be a real challenge.</FONT>

Well, diesels do need it. Maybe not the Kubota diesels, but I've seen some really interesting results that resulted in huge amounts of sparks. But the Kubota is not a 1940's locomotive. </P>


The reasonthe screenmight become cloggedis pretty much limited to hard acceleration in cold engine situations. This would result in unburned or partially burned fuel. </P>

Well, it would be interesting what kind of diesel fuel he was burning in it. We have some running their own product in their tractors around here. I am not saying that is the problem but I run green over the road fuel in mine. Has the winter additives and I feel better with it-that is just me. I know it cost me the over the road taxes too-I pay it. I want to run the best fuel and oils possible in my equipment.</P>


Also, I have the owners manual, shop manual and parts book for my 1100. I have not gone throughevery page in it but the only mention I found is the 100 hour service.If I have missed it, maybe someone could point me to the otherplaces where this is mentioned. My books says "the screen type spark arrester should be removed, cleaned, and inspected<U>after</U> every 100 hours of use". I would say as a result of your post many of us will be giving our spark arrester more attention to prevent the potential problem until we know how our rigs are going to act.I am not saying thisis an example butsometimes wonder how much research has gone into these new mandates we are forced to follow-such as engine time and long term effects.I have a boat with a 496 Mag Mercury engine in it. I grow corn and soybeans. I am worried about long term effects the 10% additive has when left in my tank over the winter as are most of the other boaters. The water wants to separate out when left long term. Yes I usethe fuel stabilizer recommended. I hope it won't be a problem, but I don't know and have not had anyone swear it won't be a problem either, and put money where their mouth is. Got that off my chest.</P>


End results, most of us will check it more often now thanks to reading this post. In my opinion another good reason to read this forum. </P>

There's the main thing...

Now, tell me. Does the arrester that's on the end/tip of the 900's exhaust fit the 1100? (Is the exhaust pipe the same diameter?)

If so, and I had a 1100, I'd probably remove the 1100's OEM version on the first maintenance and put the 900's version on the tip. Much easier to inspect/remove/clean (or remove altogether when not needed)? They're probably only a couple bucks.

Do note that if you're riding on State or Federal lands, I believe it's a required item.

Now that would be the thing to do !!!! Great Idea !!!!

Not sure if the one for the 900 has as much surface area as the one inside the 1100 muffler does and it may clog up faster with the larger engine.Pulled mine of the 1100 the other day and with 57 hours it had medium buildup, just comes out with 2 allen screws. There is the Super Trap Muffler that has disks thatare stacked and it is rated as a spark arrestor also. To clean it you just unscrew the cap and clean between the disks, if you want more capacity for larger enginesyou just add more disks to the system may be an ideal replacement for the stock arrestor. Jacks Small Engines has them in stock.</P>

Yep, it's not needed unless you are running around on USFS/public land and I believe the main clogging factor here is altitude since diesels will pour out smoke at high elevations. The exhaust pipe diameters are them same on both the RTV900 & 1100, but removing the internal screen on the RTV1100 would not be pretty.

Re: 1100 &gt;&gt;&gt; Removed IT &lt;&lt;&lt;&lt;&lt;

Two Guns I see the two screws that hold the tail pipe end on the muffler. If I remove them will the pictured arrestor pull out of muffler? then what can this be pulled apart by hand and the contaminated arrestor just be discarded ? Do I need to replace with something else or just re-bolt the tail pipe end back on with the arrestor removed.

Re: 1100 &gt;&gt;&gt; Removed IT &lt;&lt;&lt;&lt;&lt;

JohnR: I removed the tail pipe end from my 1100 andtheendseems to fit in a hole in the muffler. To remove it, use a 5mm allen wrench and then you may have to twist it to break it loose if it has a lot of build-up. Mine has 34 hours on it and it had enough build-up you couldn't see through the screen after removed. I am not real happy with the amount on mine. No mountains, no quick starts, no cold weather, no etc........... The screen is a stainless steel screen, sealed on the end inserted into the muffler. I cleaned mine with a hand wire brush. It cleans right up with no problem. I put it back in with a twisting motion until seated. Then I put antiseize compound on the threads of the screws before putting them back in, because much like a head bolt-difficult after heat and rust build-up, to remove. I will probably get an other tail pipe end and gasket to install on mine. I plan on keeping the original incase I ride on the lands where it is required, otherwise I will ride without it. I am afraid what it will cost from Kubota-they are proud of their parts-headlights, rear screen etc..... It is not that much of a problem to clean but I don't want to have to clear it as often as it seems it will be required. I think if I go to 100 hours as recommended, the efficiency of the engine will not be what it should. That is my opinion and that is what I am going to do. Again I don't ride in areas where it is required according to USDA Forest Service Standard 5100-1c, "Spark Arresters for Internal Combustions", which is sited in the owners manual and service book as the requirement for it being there in the first place. Look it up and see what you think. I would not want to ride without it in the required areas.</P>
