The Doughnut Tradition

2 Thess. 2:15 So then, brethren, stand firm and hold to the traditions which you were taught,

When I was growing up, and the weather looked like this:


You made doughnuts.  I don't know why my mom started that tradition, but since it is in the Bible, I feel obligated to teach it to my children also.  So here is what Amanda and the kids whipped up this afternoon.




As you can see the kids were not disappointed.  We did this last time we had a significant snowed in day a couple years ago.  And I have always loved these pictures of the kids a couple years ago.

These are shims.

For all of my blogger audience that has been breathlessly waiting to hear the conclusion of my latest tractor repair, well I have my parts in now.  I hope I will have time maybe Saturday to get it all together.

It took so long I think these parts had to come from a warehouse on Saturn, and they were having trouble finding a good launch window to ship them here I guess.  Also I think they may have gotten tied up in customs when the rocket splashed down on the China coast.

 Shims and gaskets for the cover. 
Very very thin.  

When they get out of place they turn into junk, which was what I found when I drained the oil oh so many weeks ago.  An oil analysis I sent in showed everything to be normal.  

Hope hope hope this is a $150 repair, and not $28,000 re-manufactured transmission.  (Yes, that is what it would cost to put in a re-man.)

Now for the fun stuff!  Here is a Knuckle Buster in training.  Daniel got this little erector set type kit for Christmas.  Never to early to teach "righty tighty, lefty loosey"

One of Fenton's favorite things to say is "Hot!".  Yes sometimes he will get it right, when he sees coffee or food steaming, or when he feels it.  But sometimes "hot" is anything that is shiny, or when we go outside and the cold wind is blowing, or a cold piece of cheese.....


At the very beginning of the video when he is rubbing his chest, that is what we taught him to do for "please".  Surprising how quick he picked up on it and will "say" please when he really wants something.

This video is kinda long, but Mikali is in it.  Don't want to leave her out.

More busted knuckles

I was so proud of my big red tractor until about a week ago I decided to change the transmission oil.  Since I bought it used I had no idea how long it had been since it was changed, so it is good to start out fresh.  AND sometimes when you do stuff like this you FIND.........


No, I did not find a quarter in the transmission.  I found these ground up metal shavings.  Rut-roh.  Here we go again with my tractors.  One thing after another. Is this one going to be the Big Red Lemon???????

Well after quite a bit of fretting around and asking lots of questions on an Ag discussion forum that I read a lot, we finally decided it was probably some shims from behind a bearing holder.  (red circle, goes in blue circle hole)


Problem is as usual they put this part on the assembly line first, then built the tractor around it.  To access this little feature, took some very difficult contortions on my part, and removing some of the driveline parts.  And when I finally got to it, yep, that is where the metal came from.  No doubt.  Quite a bit of relief, even though it is a hassle.  Because I think, I am pretty sure, I hope, crossed fingers, I caught the problem before it really became a bigger problem.  Always good procedure to do regular maint. like transmission oil changes, and catch stuff early.

This holder had a little groove worn in it where the shim (very thin doughnut washer like thing) had spun around and come out, letting the bearing race turn in the housing.

New one is about $575.  No problem, just throw it in the handy dandy metal lathe, and smooth it up a little.


Here is where it came out of.



This is what it holds.  It is hard to tell on the camera, but that bearing is a big one at almost 4" across.  These transmissions are built really heavy.  The holder sandwiches the shims against the bearing race, keeping the bearing just the right tension.  (bearing race is the bright silver ring outside the rollers)  The race had just started to get a little loose in this bore.  But I have a plan.


 I had to set up a dial indicator that will tell me approximately how thick of a shim to put in.  I have an assortment of shims ordered.  When they come in, I will start with what the indicator tells me, plus a little extra.  Then I will assemble it, check, and adjust from there.  It is important to get just the right pre-load on it, as setting it up too tight and it may overheat the bearing, too loose and it will beat out the bore where it rides.




When I put it all back together I am going to try a special locking glue that is made just for these types of situations.  It is supposed to hold bearing races and not let them spin.  Fingers crossed, I won't have any more problems.
