 Posted: Tue Oct 02, 2012 8:21 am Post subject: Rain and Gear Shift Boot? |
  |
|
In the past I saw an article on here where someone did a test to see if rain water can actually enter at the point. They did the test with no shift boot at all on it and still no rain entered at that point. The link had pictures of the test.
Can anyone give me a link to this test please?

i call bull hockey! the shifter is a shaft with a
ball in the middle and a shaft out the bottom, it
fits in a round type socket and unless there is
grease packed tight around the "ball" water will
flow right into the transmission. the old 8n i had
got water in it that way, i drained water out of it
after it sat outside for about 3 months, i put a
boot on the shifter and it sat outside always and
got nothing in the trans after that....

I am aware of the mechanics of it. I did not make this post for opinions on it one way or another. I just wanted access to that article.
Please let's not make this a pi$$ing contest one way or another whether moisture will enter at that point.
If that's all you guys want to do then please don't bother adding to this post.

I think John Smith did the test, maybe check his site.

Yes, before the web provider changed it was there, but no more. Besides the pictures, test method, etc., it is really very simple, you have a ball & socket held tight with a spring & splash lubed with oil slung by transmission gears, so if all is intact & not worn out, water won't get past ball/socket/oil, which he demonstrated with a plastic bag taped on bottom of transmission cover & a water hose running water over shifter without a boot for 5 minutes. Most believe condensation is the primary source and second the unsealed draft control plunger opening. I keep mine sheltered for a multitude of reasons.

" i call bull hockey!"
This isn't Global Warming we're talking about. No opinion involved.
I recall the post. I too thought a bad boot would cause water to get in the tranny until I saw the video test that John Smith posted.
It's not 'bull hockey.' It's a fact & the test showed it to be true.

I replaced the boot on mine a couple years ago. For the record I have never seen water in my system but I do keep that draft control spring covered.

Well, that's with everything working correctly as it should. But what happens if some dirt or grit or micro shavings from inside the trans get up in there and build up and maybe clog up between the ball and socket and maybe dry up in there creating a path for moisture to enter? So...it's kind of hard to disprove that. Good enough reason to keep a good boot on there.

Agreed.
The oil film will displace water for a time but if left outside for long periods the film will dissipate and water will enter.

I agree. Your tractor, your choice.
What I find interesting is that anyone would choose to leave a tractor of any brand out in the rain for long...

If you still have the old link you may be able to find it at this site. Copy the old link and paste in the search bar, it will show multiple backups of a lot of old web content.

It has been a while since I have posted here, though I like to read the threads.
This reply also speaks to the "lift power" thread.
I"ve had an 8N for almost 30 years and use it regularly, but not as often as in the past.
Like a dummy, I did leave it out in the rain for a Northern Californian winter or two with no shift boot.
I was kind of proud that the tranny/diff oil didn"t seem to go down over the years.
I did notice a loss of lifting power and maybe even an increase in hydraulic level.
Tore down and found a hyd pump that looked brand new after 40 years.
The cause, of course, was water in the oil, at the bottom where the pump draws its supply.
Water makes a lousy hydraulic fluid.
Upshot: replaced hyd oil, everything works great and it stays under cover year round.

Hmmm.....I never noticed, I'll have to try that tomorrow. I usually take one of those two wheeled V shaped garden carts and turn it upside down. It fits in there nicely.
