Had a busy day planned on boiler servicing today and a couple of plumbing repairs. Managed to get 4 services done and then got a phone call to come home.
This lady had decided today was the day to unload her precious cargo :love:

Still, cracking afternoon for it :)

Can’t say I’m impressed with the in-laws offering of a dog though, got it for a few days while they’re away :rolleyes:

Apologies if these get a little repetitive but this has pretty much been my day!
6630 head on and torqued down.

Injectors in.

Rocker box on, valves set, then as I was thread locking the injector wire retaining nuts on it got me thinking, am I charging enough for lock tight:sneaky::ROFLMAO:

Charge cooler, Egr system, and thermostat housing on, always feels like your on the home stretch at this point:)
View attachment 766678

And finally, exhaust system, coolant in and fired up(y) run it up to temp and checked for any leeks and it’s another job done.

Had a couple of hours cleaning bits on the 6830 ready for tomorrow, and that was about it for today:)

So what makes these JD head gasket thingies give up all the time? Do the replacements fix the problem or can they go again after a few thousand hours?

How much do you charge for this and how far can you go direct from tank?

We only have very big self propelled ones around here that roll hose up when going. But they are very heavy and can’t go yet. Like agrometer sds 8000 or something like that. They charge 20 dkr/m3. Thats 2,35£ in todays money. They go up to 1000m plus the 800 on the machine. Moving to buffer tank will at least double the price, more if it’s more than a few km.
Can go any distance the customer wants,I’ve only got 1800m of my own pipe but can hire extra pipes and pumps as need be,we have been involved in pumps over 4000m on one place (y)

Can be any number of things that makes them go to be honest, on this one the egr cooler had split which 1 leaks coolant into the exhaust when stopped and 2 airlocks the system when running. But blocked radiators and getting hot is another cause, or they just go.
As far as going again, all’s I’ll say is I don’t get any repeat business from head gaskets(y)

I’ve been told a different story about bolts that where a little too long, so they reached the bottom of the hole with too little pressure on the head. This is straight from dealers shop. Fix is new gasket and shorter bolts.

Also rumors that deere where a little too eager to sell them in 06-09 where they sold like hot cakes. Something with curing time, and liners that settled a bit down. Especially a problem on 8530’s around here. Claas made a fix for this with a thicker gasket, which my “garage mechanic” put in my 7830 a few years ago.

Nothing to do with bolt length, they changed the tensile strength of the bolts.
Note the old bolt just come out of the 6630 is a 4F

New head bolt is a 5F which is tightened down more during the updated torquing procedure.

Yes there is around 10mm more thread on the new 5F bolts but both are exactly the same length.

And both will only screw into the block exactly the same distance.

As for curing time, most head gasket replacements are running within 5-6 hours of the head been torque down.
And a total engine rebuild with new liners will be running by the following day!

As for the 9L engine fitted in the 8030 series that’s a totaly different setup the the 6068 engine used in the 6-7000 series. You need a 3/4 bar to torque those heads down!

Rickerbys Claas dealers near us tap the threads a bit longer in block when the Claas tractors go in for head gasket replacement, and they fit a a Claas gasket which under normal circumstances don`t fail again unlike the John deere ones which seem to have a fairly short lifespan

Not sure who’s doing these head gaskets if they’re getting regular repeat failures! Think they need a kick up the arse as there’re not doing something right:scratchhead:

Would that do osr straw
Also how long does it take for a round bale

Just a hammer mill so would do OSR no bother - probably too well as the straw is very brittle and could dust it? I suppose you could slow it down &/or make other adjustments

Round bale would be done in minutes. We did 2 artic loads of big bales in 6 hours

I just tell you what farmers have been told around here. There have been replaced a lot of head gaskets around here. On the 9l it would be a shot term fix to just put a new because the liners drop just a bit. There is supposedly a kit with shims or something like this to align them again. If it’s done like this they don’t come back. If not, they can be back later the same season.

For the 6,8l i know several who just had a new deere gasket like the original one changed more than once. The class one has not be replaced where i go according to the mechanic. They don’t use deeres anymore.

I know more than half is rubbish, and a lot of stories get throughn around when people spend this much money on a widespread problem that shouldn’t exist in the first place. I just have no way of knowing what is true as i just own them and pay the bills.

Today (actually yesterday for the pedantic) we have been busting straw in a rotagrind

To get to this (2 artic loads)

Ignorant arable farmer here;
1- wouldn't be chewed up a fair bit in the diet feeder with knives in? I assume you are putting it in one for 'scratch'?
2- People say don't buy axial flow combines ruin the straw, I'm going to buy one and charge extra for pre-chopped straw........

Takes too long in a diet feeder and uses more fuel. The readout on our 6195 suggested it was using around 18 litres an hour to use the hammer mill so cost me about £60 in fuel to process 2 artic loads. Would probably triple or more if we tried to grind it in a tub (plus they aren't really designed for this sort of job)

If we could get straw that had been though an axial flow, we would every time as we feed tonnes of straw a year - all our heifers are reared on straw & nuts
