RTV sounds like something is engaged but not

My RTV 1100 "09" making a sound that I have not noticed before. It sounds like something is engaged but there is nothing engaged. It was making this sound a week or so ago. This is what I did before. I have changed the fluid in the front end and both front hubs. Took it for a spin and still hear the noise. Checked all other fluids. All fluids were changed less than 25 hours ago. Also sometimes it will start in gear. This machine has 131 hours. It sounds like it is in 4wd but its not. Also I have greased the u joints. Any Ideas?
 
Welcome to the forum.

Tough to diagnosis a sound. Do you have the means to get the whole RTV off the ground (where all 4 wheels are suspended)?
 
Welcome Kevin,Did you hear the sound before the change or after? Where does the sound seem like it is coming from?Do you have the 2 pc drive shaft or the updated one? If the 2 pc one, check the carrier bearing (where they meet at under the seat area). Also, did you go back with UDT when you changed the fluids? Have you removed the spark arrestor yet? It's accessible thru the 2 bolts at rear of muffler.
Like BCZoom suggested, it might be helpful to jack it up and check things out. A good jiggling of the tires with it jacked up would let you know if you had a noise such a bearings causing problems there.
That's just the safety switch letting it start in gear- it is easy to replace if that bothers you. bordercollie

Safety Switch Location

This is the location of the safety switch on my '05 900.That's it in the center with the white plug. I have sold the unit but kept plenty of pictures . :) bordercollie

Yes, Like bordercollie, I also have to ask the question. Did you use Kubota Fluids and filters ? And the spark arrestor, were do we stand on this ?
 
I have not removed the spark arrester. Will that give me more power? I did use super UDT and also kubota filters. I did hear the sound before and after the change of fluids.
 
watch removing the bolts,i broke the last 2 i took out. best is if they brake to try and turn them back in, i took a 1/8 drill bit drilled them through,then took a tap and tried to run it through the bolt,it turned it right inside the muffler.inside the muffler is a weld nut,so try not to put too much torque on the bolt.
 
Don't know about anybody else. Used penetrating oil all my life. But I purchased a can of
Amsoil penetrating oil a few months back. Finally used it the other day. Never seen anything
work like this stuff.

There was a couple of nuts I've try to remove. Could not budge them. Sprayed the amsoil
pent oil on the night before. Went back the next morning and sprayed again. About a hour later.
BINGO, they came off so easy, I would have swore somebody never tightened them up ...
 
You will be shocked at how that spark arrester will be clogged.... Two Guns has pictures on here somewhere of the typical clogged up one.
While we are thinking about different possible causes, the parking brake- adjustment? bordercollie
 
it has always been a smooth sound in the cab. just lately it has this grinding noise. I carried it to the Kubota dealer. they can not find anything wrong. but i am hearing a noise that I have not heard before. Will check the parking brake.
 
Kevin, maybe someone can drive it while you walk along side and trace it out. When you changed the trans fluid 25 hrs ago were there filings on the magnetic plug? At my first change on my new '11 900xt , the magnetic plug had caught a good deal of crud. I hired the rear ujoints replaced the first time on my '05 in 2008 and caught the transmission level about a gallon low after that work was done. I heard a whine and was glad I checked it. I do my own work when I have the knowledge after that experience and will always check behind even myself. I did my own '05 rear ujoints the last time at a significant savings too.That's another post though. So this sound started well after the last transmission change? And the filters are on correctly/ orange in the rear (on the 900) yellow on side....If you have checked the wheels as BCzoom suggested and not heard anything when rotating them, and the carrier bearing, parking brake, muffler ,then we are working back to the trans area for the sound .... Good Luck bordercollie

Does it change pitch if you turn your steering wheel (thinking of power steering here)?
 
Do you suspect it to be coming from the front or the rear. You mentioned it was like it was still in 4wd. This sounds to me that you may feel it is in the front. If you follow bordercollies lead and recall if your plug had alot of shavings or "crud" it could help in ruling out the front differential or not. Grab a jack and some jackstands and jack up the front end. After you get your jackstands under it (the rtv) and it's resting securely on them you can check your hubs. Grab the front tire, one hand on top and the other on bottom. Alternate pushing and pulling with your hands to see if you have any play. Top hand push bottom hand pull, then top hand pull and bottom hand push. Do this on both sides. We have had to rebuild these many times. Try spinning each tire to see if you hear the noise. If you hear anything, try to isolate it to a particular part. You can also do this to the rear as well. Jack up the rtv, place it on the jackstands and test the rear. Try spinning the wheels, listen for noises. Engage your park brake then try to turn your rear wheels. You will have a little play forwards and backwards when you change directions. Once your propellor shaft stops turning, due to the brake, try to make the tire turn. Look for any "slip" on the wheel or play in the u-joint. You can notice these because the propellor shaft should not move so any form of play should be spotted easily. Try the push-pull method like on the front. I have had a few that had bad bearings or bad u-joints that will make a grinding noise. Hope this helps you, good luck.

Oh, the neutral safety switch that bordercollie mentioned before is the culprit for it starting in gear. Check to see if it starts in all gears or just one or two. The switch sometimes needs to be shimmed. If it starts in some gears but not the others then this is the problem. If it starts in all gears, try loosening the switch a complete revolution or so and see it still starts in gear. If it doesn't start in gear after loosening then the shimming is your problem here too.
 
With the way sound travels it makes it hard to find for sure, with the low hours and i bet it has been cared for well nothing can be wore out, i would be looking for something rubbing, a rock stuck between a shield, something between the cab and frame, most of the time i over look the simple things and make it harder on myself.:bonk:
