Newbie question

Joe 77 B100

Hey folks.  I was gifted 77 B-100 and I got it running.  I haven't tried to move it yet because it has a blower on the front and a part is missing.  Different thread.

 

But, when I start it, it sounds great.  When I release the clutch and I don't have it in gear, it starts making a fairly loud noise in the transmission.   Not a bad "something is broken" kinda noise but just a "something is engaged" kinda noise. 

This might be a really dumb question, but shouldn't there be nothing moving in the transmission if i am neutral?  Thoughts/

Thanks in advance.

The input shaft and a gear shaft will be turning. The idler pully that puts tension on the belt could be the source of the noise. Have you checked the oil in your transmission? If there is water in the oil it could be frozen if the tractor isn't in a heated garage.

WHX??

The cluster gear will spin when in neutral so it's possible either that and/or the input shaft has bad bearings/bushings. Drain the oil and report back what it looks like with a pic. You should change tranny oil on a new to anyway. Like 'Nut says it might be a bad drive belt idler bearing so take look at that too that's easy.

The drive pulley on the transmission could also be loose on the shaft and be rubbing the belt guard.

This could also be something with the belt idler/clutch pulley.  Pull the belt guard, check stuff in there…

 

and if I haven’t yet,  :text-welcomeconfetti:

You guys are freaking awesome.   I will check all of that stuff.  If you have pics, it will make it easier to find what you're talking about.

And, I drained all the oil out of the transmission and it has all new oil.  I will send  pic of what was drained out.  It was brown, not pink.

That oil had better not have been pink.  A manual transmission needs 90 wt gear oil.  

    Cold is a concern.  Is the horse in a heated space??  You may have to let it run for a bit with the trans in neutral to warm things up.  Anyway, you could give us a short video, so we could hear the noise.  As was stated, check the things outside the trans first.  Remember, you can run your horse in neutral without the belt guard on, but do not try to shift it into gear...you will just grind the gears in the transmission.  :occasion-xmas:

I had read that some people were putting ATF in their transmission but I am using 90W-140 per the manual.

What/where is the belt guard?  I haven't tried to move it yet so I have no idea if the transmission is good but the PO told me it "moved" fine and I know him well so he wouldn't lie about it.

I will try and find a schematic or image of the belt guard so I know what I am looking for.

And, I WILL send a video in a little bit.

In a MANUAL trans?  That ain't right.

 

In a HYDRO AUTO trans, maybe, yes.

@ecojoe69  would not be surprised if the idler pulley has something to do with your noise, those undersize bearings and lubrication failure is a major reason for noise / failure .  try to verify what's going on when running , get some help to have someone slowly use what you have , to find noise and binding spots .  every part of  a function has a say as to its operating or not , pete

It is a manual.  I'm gonna warm up the shop and get it running tomorrow and I will send a video.

I found this image online.  My tractor has a guard so I cannot see the configuration as well but those two rear pulleys are the ones I assume people are talking about.  The smaller one is the idler pulley and the lower one???

Here is a pic of my tractor from the rear.  For one, the pulleys look much bigger than those in the image above which might be causing the issue I am hearing you will see below.

1038098242_drivebelt.jpg.7376b73a48fcf99c740e63e9b80a34c3.jpg

In the image below, you can see from the left side under the tractor that the belt actually sits on the belt guard which is what is causing the noise I hear when I release the clutch.   I told you it wasn't a bad noise, just something moving or working.  So, the noise is the belt rubbing.

I assume I am going to have to adjust tension somewhere.

Can someone 1) tell me how to do that and 2) post a schematic of what those distances should look like?  I think I saw some clearances in the owners manual so I will go back and check that again.

Your belt, from what I can see, looks good. It doesn't have the appearance of a belt with a lot of wear. The picture below with the arrow is showing the pulley that sometimes will make a lot of noise.

agree with @rmaynard  on that upper pulley , another thing is to check out the function and / lubrication of related linkage to this area, typically neglected , and bound up with rust , creates a lot of issues. would not be surprised  in the idler pulley , noisy bearing failure. should be easy to match up . pete

The more I look at it, the pulley must be too big.  There would be no way for the belt to NOT slightly rub on the belt guard except to have a smaller pulley.  Right?   I WILL go check all of the lubrication points.

Someone asked to see the oil.  There was almost none in there but what was there was fairly clean.  You can see through it when I put it in the light.

How much came out? That could be the noise issue right there… not enough oil…

 

Also did you put the front end of the tractor up high to drain trans oil? There’s a hump inside that blocks oil from plug if you don’t raise the front end…

I am going to drain the trans oil again when I run it for a bit and test it out.  Then, I will lift it and drain again fully and replace with all new. 

How far off the ground is an approximate height for the front tires? 

And, thanks again to everyone for all their help on this project.

I use regular auto ramps so it’s about 9”-12” or so… basically as high as you can safely get it…

 

Mine are like these (only red of course)…

Input of the tranny

 

It needs 2qts of 80w90

 

The white idler pulley on my C141 is to big too, but isn't making any noise. 

You should feel if the bearing has any side to side play, or is noisy when not contacted with the belt. My 314 had that pulley bad and made a lot of noise. My raider is now showing the same symptoms. The grease in that bearing will eventually dissapear.

And if you feel like it is the plate rubbing. You can't adjust the belt tension. that is done with the clutch and if the clutch engages correct. you better not mesh with it. 

Could be someone picked up the horse with a forklift or so, bending that plate. All you have to do is bent the plate back out of the way for the belt.

People keep saying to replace this boot.  Where does one find one?

Is that bolt a plug of some sort I should be backing out and lubricating?
