'57 640 Ford Tractor

[magoodwin]

My husband is working on his '57 640 Ford Tractor. He is replacing
the PTO housing. The shaft is spinning inside the oil seal surface.
Does the PTO shaft seal surface rotate with the shaft or does the
shaft rotate inside the shaft seal surface?

All of mine fit to the housing and are stationary.

 

[J. Franklin]

Wrong seal is my guess.

 

[Larry NCKS]

the shaft rotates in the seal. The seal should be a light press fit in the housing.

J. Franklin, writing my guess is a bad choice of words on here, I guess. LOL
I made a post and wrote my guess...............
Well that got a member on here upset and this was posted:

"We don"t operate on hunches here. We operate on observations and we verify things as we go."

So no more using the guess word on here.

 

[McBride]

I would guess that using I guess is the same as in my opinion so no more opinions on here I guess.

This may not apply since you said the shaft is spinning inside the seal but if you find the correct seal is in and is spinning in the housing then the housing may be worn from the seal spinning and a new seal may also fit loose and spin.
I have had good success fixing that problem by using a small puncture wound punch and put punch marks all around the housing where the side of the seal fits againts the housing. Clean housing surface good and use some Loctite when pressing in the new seal. The small puncture wound punch will make a indent in the housing with high spots around the indents that will make a tighter fit for the seal.

 

[McBride]

I guess you might say that is just my opinion, I guess. LOL

 

[souNdguy]

i'd 'guess' you've never done this repair before.. have you?

 

[McBride]

Many times but not on a 640.
Not many Fords around here I guess.
Just finished one on an Allis D-17 with a loose fitting seal.

 

[souNdguy]

like I said.

you've nver done 'this' repair before then. IE..pto seal repalcement on a ford of that type.

staking in a seal isn't something you'd do...

 

[McBride]

Ok, Your the master on this subject I guess.
Ill just sit back and read from now on.
Maybe I"ll learn something.
Been in tractor repair for over 35 years and I still don"t know anything I guess but that D-17"s seal isn"t spinnig anymore I guess.
Cheaper fix than buying a new bearing retainer if you can even get a new one for a D-17.

Wow, I didn't know that an Allis D-17 was exactly the same tractor as a Ford 640. I always thought that a PTO seal leaking on a Ford 640 didn't have nothing to do with a bearing retainer, but since they're inter-related on a D17 they must also be on a Ford 640. I guess I just learned something.

 

[souNdguy]

apparently you have poor reading comprehension as well.

my mention of 'this' repair involves a pto seal on a ford 00 series tractor.

not a D17. I'm not commenting on D17 pto seals because I don't know about them.


you would not stake in a pto seal on a ford 00 series tractor....if you had EVER done one... you'd know why.

generic info is fine.. as long as it ACTUALLY is helpfull and pertains to the subject at hand. In this case.. IT DOESN'T!

 

[souNdguy]

if mcbride would ever care to take a ford 00 pto shaft, bearing carrier /pto seal assembly in hand and take it apart.. he'd know EXACTLY why you wouldn't stake in a spinning pto seal... it's obvious he hasn't.

reminds me of when people who have never seen a ford front mount dizzy start giving incorrect generic advice on what should be done tot he dizzy, timing.. etc.. timing lights.. etc.

and then get bent out of shape when their incorrect generic info is said to not apply to that specialized dizzzy.... go figure...

McBride, Having read your post I see that you qualified it with "correct seal is in". I appreciate your post and though it may not apply specifically to a Ford x00 in this situation, it is still good information to have, as you obviously have a lot of experience. I look forward to more posts from you.

I had trouble with a mexican throwout bearing fitting a bit loose on the shaft.Some punch marks and a bit of Loctite bearing locker fixed it.3 years ago and still good.Some of these posters can spell guess so they ASSume things.Edison tried 100 different materials for his light bulb filament before he found tungsten worked.I guess he did a lot of guesswork.Soundy just gave out bum info on hydraulic oil, hes having a fit now I guess.

What saved your arse was the loctite ... What looks like paint and I guess folks would think is paint is actually a sealer that I guess seals the seal to the housing... My guess would be that a boogerd up housing would booger up the outer seal to housing sealing surface... If you have to go their to save your arse you better apply some type of sealer to your boogerd up mess...
