New Holland TM135 4WD front hub

[Laggard]

The seal is leaking oil. How hard is it to change please? Can we try or should I seek professional help?

Doesn't look too bad, the newer ones have 1 big nut instead of 3 bolts like your picture and ya need a special socket for that. Hardest part is getting the kingpins out if they're seized in there. Best way I've found is to take the bolts out and weld a piece of steel to the kinpin big enough that you can hit it with a hammer and just beat them out.

It’s stopped leaking for the moment so will see if it starts again and yes there is still oil in the hub. It was on the subsoiler when it did leak which was hard work and it did get quite warm.

Just looking through my parts diagram of the hub and it shows that big nut so mite be a bit of a mission on 2nd thoughts. Easy way would be to take the planetary cover off and have a look see what's in there.

I like the weld on technique [emoji106]

Yea works well just did a t7060 and it started leaking again couple weeks later! May have just been over full though cos hasn't leaked since.

What oil should be in the hub please?

 

[The Man]

My Tm’s the same if it’s sat for a couple of weeks it will leak a little but if used every couple of days doesn’t leak strange really.

Don't need to touch the king pins to put in the seal, I put in new seal and it still leaked so is full of grease now

Too light 80 90 is recommended

Yea you need to take kingpins out to do the small seal which seldom leaks its nearly always the big seal that goes and also to open the big nut you can make a socket with six pieces of flat

Anyone ever put a tm150 axle in a 140?
