John deere 6920 P

[Deepseaman]

Looking at second hand 6920 , Ivt , tls etc , has done approx 7000 hrs
Anything in particular to look at , they say ivt has been inspected and is good , do these tractors have any noteworthy issues

 

[Flat 10]

Yes. Head Gasket, rockshaft, Panhard rod. Lots of threads on here. Most relatively straightforward and easy to fix. Search the forum. Aswell as the autopower obviously.

How can the ivt be inspected?
I’d be more concerned about the transmission that anything else.

Autopower ones are cheap compared to power shifts.
Suppose the balance is purchase price against £12k of trans work possibility?

Local contractor fixed his autopower himself so dont listen to ppl that say you have to put complete box in

Nick Young Tractor parts can supply all autopower parts or exchang boxes if you don’t fancy tackling it.

They removed it and opened it up , so they said anyway

 

[lhf1]

Question would be why was it taken out and opened up?

Pub talk.

Not pub talk. True. He also fixed his fendt 920 vario

Exchange perhaps. There’s lots of tools required for repair. New transmission 10k ish plus fitting. Probably not the end of the world these days.

Think he had whole job done for 2000-2500 roughly. Needed new clutch plates plus somethin else

 

[tweedale terrier]

They will supply any part except the hydro unit as it’s not cost effective, I confirmed this with them at lama.
I’ve stripped a few auto powers over the years and it’s nothing to complex, just clutches and epicyclic gear sets. I did go on the training corse when they first came out though and have the training/test manuals for 6#10/20 series ZF transmission and the 7#20 series jd transmission.
At the end of the day a gear is a gear, so if you can confidently strip one gearbox you can strip any.

Must have got the parts out the back door at zf. They won’t supply individual parts.

Don’t think there’s anything back door about it, the original auto power was on license to jd and jd made ZF stop distributing parts to there dealers.
I would think the licensing has now finished and nytp has negotiated a deal with a ZF distributor/re-manufacturers to supply exchange boxes and parts, however ZF are still highly unlikely to deal directly with joe public for parts I would think.

I believe you can get all parts through deutz as they are the same gearbox , only difference deutz run with separate oil.

 

[Deepseaman]

Looks as if we may be better to keep a distance from these transmissions , did think they would be good for mowing and bailing , but certainly don't want bills down the track that are potentially worth more than the tractor itself. Thanks for all the responses, just the sort of info we were after.

Frightening part about ap is that it can cost the same for a totally knackered box as it can for an oil seal if you go down the exchange route
