I think the other seal definitely has to come out.

The axles on my Commando 8  3 speed are only 1"dia.    Did WH use both sizes?

ok..I gotta ask how this trans got 1-1/8th axles in it?????..The only 4-speeds transmissions with 1-1/8th axle's were the 953-1054 trans and they had long axles in them and the bevel gear differential....and some of those trans had bronze bushings were the axle needle bearings are now...So either the cases are from a 953-1054 or some one had the cases machined to except the 1-1/8th axle and the bore size maybe off and not letting the seal seat correctly.... :eusa-think: .....The correct trans should be a 5053 with 1" axles.

It's the trans that's been in the tractor since I've owned it Mike.  :dunno:

Are there any #'s stamped into the case, that will definitively ID it?

Maybe I'm just seeing things but the picture with the tape measure, that axle end isn't mushroomed is it? Do you have a digital caliper? I'd get one if you don't and measure it at a couple of different locations.

Craig, there are no marks on the case that would help identify the trans.  It is all about the number of pinions, diameter of axle and where the brake shaft comes out of the case.  :)  At this point, I think I would try to get that other seal out and see if you have any numbers on it.  Calipers would tell you if your axle shaft is the right size for your seal also.  Something ain't right mate.  :)

 

In your 4th picture in post 16, I can make out what is says on the seal (Made in USA), but I need a picture of the seal from the other side to see the numbers.  Either a machine shop can fix it...or racinfool40 (Mike) should have a case half for you...depending on what you find when you open it up.  If you decide to open it...make sure to have the shallow side of the trans down...you want to lift off the brake shaft side.

Only # I can make out looks like it's stamped with a 3900 to me. 

I was able to examine another 953/1054 trans at Stevebo's today...trans cases looked identical to mine...

but you're right Biser...it's axles were about twice as long, and it had much beefier hubs on it too. 

Wonder...if the internal bronze bushings used for these axles are still available?

I think this 3-speed has 1-1/8" axles also.

the 3900 would suggest that it's a right hand case half of a 5053 trans

is there 3901 on the other half? or is there a different number?

The earliest 1968 tractor serial numbers recorded so far are for 2 Lawn Rangers. Next is a Commando 8 with serial # 391687. Wonder if this one got a left-over 1967 model 3-speed  transmission since this would have happened in 1967 for the 1968 model year?

Do you have the tractor serial number?

Don't know whether it's early or late in the production run...    :eusa-think: 

but, it seems the case #'s do match...3900, 3901.

if it was a 953/1054 trans your bolt pattern to the frame would be different as well......

yes you are correct there Gary....

 

there are some differences from the 953/1054 though.....

 

some of the internals are the same (bevel gear center, gears etc ), but the cases are no where near the same

 

the 1057 of mine has different case halves to the 1054. in addition to the bolt pattern difference the axle tube castings look different and i only measured the left side but there is 1/4 difference in the length as well, 1054 is longer.....

 

some quick pics....

 

1054 (still on the trailer from the mid mo meet (awesome day!)

Serial 442475 is in batch 9 of 15 batches of 1968 Commando 8's recorded so far so it sure is not early.

Koen :flags-netherlands: 

 

the numbers on the cases from my experience really don't pinpoint a particular model or application other than a grouping or style of trans. case in point here with these two pics below. i could only get pics of the drive side of the trans cases as they are assembled and on tractors and the brake side case number is covered by the brake assembly.

anyway, the drive side cases both have the 3900 number, BUT they are clearly different castings and even the are where the number is cast is different, the earlier case half has another cast number next to it on a raised pad......

So, the new batch of SKF-11050 1-1/8" axle seals came today...  :text-woo:

decided to dig the other seal(driven deeper)out of there before attempting to put a new one in. 

I guess we should have explored that number off of it, that you were asking about Steve...

because once if punched a hole into it, a small piece of metal was laying in there...didn't want that to falling back into the trans...

took a small pick and a screw driver to carefully lift it out...sure enough, that little piece of metal lying in there had nothing to do with a seal at all...

it was actually just the end of an alxe needle bearing instead.    :eusa-doh:

Decided...well, I've got nothing to lose at this point, so I cracked open the case so the trans guru's can have a peek at the guts in it...

then discovered in my haste, I should've let it drain a bit longer before I did. So here is where it sits tonight. 

:banghead: Guess I'm going to need a # for the needle bearing I have to replace now...

and some assistance from the forum to help me get it back together in one piece.     :thanks:

anyone for chocolate milk?

 

threads aplenty on all the bearing numbers Craig. Steve`s sticky (sounds kinda dirty?) in the trans section has all the numbers you need...... :thumbs:
