ID and brakes

Got a MAssey 40 I think, it has a m34 loader that in my humble opinion is overbuilt. But the serial number is 9A235987 for the tractor and L811011493 for the loader. The problem is with the wet brakes. It was leaking fluid because the seal was GONE and I mean gone. I order two the first being the inevitable wrong one and then the right one from a local dealer. The problem is it still leaks. I noticed that the seal doesn't seem to fit the actuator rod shaft tight at all and was wondering if there should be a band or something to seal the shaft to the boot? I've ordered another new one to see if anything like that comes in the package since it didn't last time. Tell me if I'm right or wrong please, was accidently raised on a GREEN farm. By the way the tractor was originally yellow.
 
Measuring the shaft (with a digital caliper), the step depth of the pocket, and the ID of the seal bore, will make the correct seal (from Motion Industries, or other bearing company) available. Delerships are my last choice for commodity parts. The seal lip should deflect a few thousandths when placed on the shaft. Jim
 
just put new brake seals on a 270 massey. On it the seals fit the puller shaft to the brake in between raised places which require pushing the inside part
of the seal over the first raised place to fit in between them. I used a 3/4 inch deep socket and the small end of a small funnel with some tire lube and
it worked very well.not sure of what yours are like, but the 270 has wet brakes like some others I've had experience with.

Understood everything but seal bore ID?
 
(quoted from post at 17:55:45 11/24/22) It is the outside diameter of the seal,measured where it fits into the housing. Jim

Thanks. I've been ordering OEM stuff but guess they don't make um like they used to.
 
Is the shaft worn where it should pass through the seal? You may need a "speedi sleeve" on the shaft to take up the wear.

Also, is it possible that this is just a dust seal and the real oil sealing is done somewhere internal?

It's what is listed as oil seal for actuator shaft so I guess it keeps dust and oil in or out but fails miserably at both at present. The part that goes in side has a metal sleeve around the edge that fits it in and is driven in by a mallet and 1 1/4 socket which works really well. I've order another one since they are cheap and and will look into a speedi sleeve? Thanks again. Did you see what model it could be. I got anywhere from 1967 to 1976?
 

Does anybody know if there's a tiny round (ring) spring that fits on the boot after you put it back on the actuator shaft, saw one on the install video but cannot find it or a picture or a part number and the dealers are lost also.
 

Is this the seal you are asking about? If so, it is more a bellows than a seal so some of the answers here would not apply.

If it is, do you have the inner opening of the bellows (seal) fitted to the raised area, between the ridges, on the actuator yoke, as oldwrencher mentioned (the 270 brakes are almost identical)? it should be tight when installed in that area.

Do you have the MF 40 service manual?

That is it. There was spring (garter spring) that fits over the inner seal wall after the seal is slid over the yoke. I saw one disassembled and it was there. I've found them online from a manufacture and needed info was the dimensions of the old one that was gone. They had put the wrong actuator rod on it to begin with so I have the right one with a new seal boot on the way. Don't do stuff halfway so all new all the right stuff and it'll be like brand new. Thanks for all the help. Pictures were very useful.

I don't' have manual, where do I find one and what would it be called?

It would be called a Massey Ferguson 40 Service manual. The base publication number is 1448979. On the agcopubs website
with an M2 suffix it is a "packet" (they sell you just the pages, you assemble it in your own three-ring binder), and with M93 suffix it is an assembly (they sell it to you assembled in a three-ring binder). You save money purchasing the packet.

They also sell the Operator's Manual, publication number 1448086M5). Here is a link to the AGCO Publications site for the 40 series tractor publications they show.

http://www.agcopubs.com/default.asp...ediaType=&category=44290&searchForm=1

You can use the publication base numbers to search places like eBay for used OEM manuals, or if you are looking at vendors with reprints, they should show the publication number they reprinted.
