Mf6480, looking in the transmission.

[Sprayer 1]

I've just dropped the oil out of the back end of the 6480, and some silvery sludge came out last. Is there a plate you can take off to inspect the brakes and transmission or do you have to take the bell housing off.
Thanks for any advice.

Meant trumpet housing!

 

[Farma Parma]

Trumpet housings off & id pretty much say thats brakes
how many hours? & is it a 50kph one?

 

[Sprayer 1]

Yes, 50k. Only 4100hrs and always very brake considerate.

It's clean, nothing in it.

It's clean, nothing in it.

if its clean I would say you brakes are OK as thats normal full of bits if the brakes are on there way out if you still have some oil you took out you could send it away & get a oil report done on it then you will have better idea, is the gearbox & Clutch calabrating OK ?

Everything seems fine but have spoke to a main dealer who says the hard facing on the diff can sometimes flake on tractors of that year and the diff is a bit noisy on the road, so I'd better investigate .

That's going to be a very expensive job if it's to unzip

Yep, I fear you are probably correct.

Is all dynashifts not 40k?

 

[masseybreaker]

yes missed the 50k bit
it could be brakes ,hand brake , pinion bearing into rear diff siezed and wearing housing i would look at brakes first and swop discs anyway they should be a service item in my opinion

Is all dynashifts not 40k?

Thought they were all capable of 50k, but enabled through software. I'm told D6 40k won't engage 4F ratio?

A dynashift would have to rev on out to get to 50k

 

[David.]

Sorry, mines a 50k Sisu Dyna 6.
Maybe different?

Not correct they do engage 4f but only rev to about 1900 rpm in that gear.

 

[Db990]

Brakes are definitely the most likely/common so I would start there.

 

[Farma Parma]

D6 40k & 50k isnt identical 4th gear ratio is taller in the 50k version thats why they will clock 56k flatout
40k D6 has limiter on 4F around 1900revs which its only doing 44k but even if you could rev it full throttle it would never get too 56k
old 32speed Dynashift flatout in 4D is only around 40k 3000,6100,6200 & early 6480s & bigger series likewise.
