We have an old diesel John Deere 95 square back still in use here.

I have no intentions of retiring the old girl for a few years as does the 250 to 500 acres per season quite nicely.

Have had a fairly soothe run till this year only with various bearings, one final drive, belts etc on the up keep.

This year I'm having issues with the fuel injection pump as is the CDC type that dont seem to exist any more here in Australia (nor do any parts)
AFAIK its the 6-303 plant engine and are not commonly found here in Aus. Perhaps a few early cotton pickers and gen sets etc.

The pump dried out and all the seals have now failed so leaks like a sieve.
I took the pump to a diesel specialist but unfortunately they have have upset the governor wile tinkering with dodgy seals etc.
We have located a seal kit in italy of all places and I think I may have found a pump over your way.


The pump is a Roosa Master CDC 633____4DG

Part no..... AT2 3057

Weird looking thing too, I never seen a rotary pump like it before.

Uses a rack arrangement for the governor control.

Anyway, I'm determined to get the old girl running again and hope to by monday.

I'll post some photos soon as I find time.

Get your mitts on a copy of the John Deere tech manual, SM 2045 Testing and Servicing Fuel Injection Pumps and Nozzles.

Mine is dated October 1971 and it has a detailed chapter on that pump as well as all other Roosa Master pumps in use during that time, along with the pumps and nozzles used in the two cylinder diesels as well.

I have seen this manual often on Ebay.

Thankyou for the pictures. Would love to see some pics of it working one day. Sounds like your keeping her upto scratch. Hope it continues to serve you well for the years to come.

Cheers

I'll get some pics up soon when she was working last year.

Having trouble getting the injection pump seals from Italy, I believe they're on the way but who knows how long. :confused:

I have literaly run into a wall searching for a second pump so have found a 1969 105 with the 6-404D engine fitted (4020 tractor engine)
She hasn't been in use for over 20 years and looks like it too!

Unfortunately the previous owner fitted en electric fuel lift pump with no return valve so the injection pump will be shot as been dry for years.
I oiled up all the chains etc and the separator looks fair other than the dreaded rust in familiar places. The concave is seized etc.
Has newish looking air flow sieves and drum has been balanced etc.

The belts all look 90%, Tyres all perfect bar one witch has a major repair.

Thankfully the 6-404D are plentiful here in Aus so have located a S/H pump for $750
and an alternator for $200 if I need them. The starter motor will need an overhaul as well.

I may save her either way as could do with a second header/combine as a back up.

Other option is to take the 6-404D off the 105 and fit to the 95. Would go well with 102HP.
this would be a pain with the auger drive etc.

A few over here have fitted the perkins 6-354 on many 95's.

Not so funny, just had a phone call from another farmer with a 95, he has just overheated his and blown the motor, is a gasoline engine.:(:D

Looks like a few heart transplants may be happening over this way soon!

Well, what do ya know. A miracle has just happened here!

The parts fronted from Italy for the CDC pump off the 95 and she's all reassembled and has calibrated fine with extra 10%.

Off to grab the pump now and the 95 should be back in action latter today.

During all this saga I tracked down the previous owner who told me it had pump issues back in the 80's and he couldn't get the parts to solve it so sold the machine.

Also, picking up a pump and alternator for the 105 I have acquired.
I'll still get the 105 back into commission over the next few days..

Will be a sight watching these pair of dinosaurs working together in our wheat crop.

Its alive! Its alive!!!

Just back, fitted the pump, timed it all up etc and she fired staight up and burst into life like never before. Runs absolutely beautifully. Idles back etc, very snappy getting up to speed. Now Governed at 2650RPM. I'll run it at 2500.

The JD 95 (and the 55) were very popular combines here in Sask. years ago. I don't ever recall seeing one with diesel power though. All gas burners. My uncle had a round back 95 and later on a square back. I have some video of it working back in 1987 picking up a light swath of spring wheat.

Well, finally here she is in action.... Looks a bit weather beaten, but for a 44yr old machine is fair. Runs like a Swiss watch.


Harvesting oats under sown with Lucerne. I'll round bale the remains.

Into the Barley tomorrow, then the wheat in a few days time weather permitting.

Had some issues with the grain tank unloading auger belt, cant get one the correct length in AUS overnight so have modified the auger drive to accept a common C section drive belt. It seems the 95 series ran a number of belt configurations depending on the engine option etc.

Hello all, just an update due to fact I have decided to keep this old girl going for another few seasons (if we get them).
The 95 has been sitting in a shed for some years due to fires and 4 years of drought here.

The old 105 we talked about above ended up not being viable to resurrect so still sitting where I found it.

A neat 6600 came up recently but I missed it and they're getting a bit old anyway. I think better off staying with this old 95 and wait for a bit newer combine to come up such as a John Deere 9500 or perhaps a late 8820 for little bit we do here. I certainly don't want much more than a 24ft front in these hills!



There has been a big change on our seasons so looks like a possible harvest coming up in summer.
Oats crops in, now sowing barley and also a lucerne barley cover crop when frost lay off.

My own doing, sadly, I haven't had time to visit the 95 combine so couple of flat tyres, massive hydraulic oil leak and fuel system will be in question if dried out again.
I also recall some other maintenance will be required such as straw walker bushing etc.

if you want parts, have a 96 sitting outside the yard with new rub bars, concave, and feeder chain ...
it's your's for free if you can get someone to take them off [i can't anymore]

Had a closer look at the 95 this avo.
Looks like I might have to pull the powerpack (engine) off the combine as there is a serious problem with the in sump oil cooler.
Sump off job and I'm not very optimistic of finding a replacement so will probably do away with the said cooler and block the holes.
The thermostat housing is also badly corroded.

Hydraulic oil looks to be around reservoir and pump so not a big problem.
Belts all look good as been in a shed as are bearings I hope.

I bleed the fuel system but have not attempted to crank it as yet.

This is the 303 diesel used here in AUS.
Not a very good picture, but you can just make out the coolant hoses running into the lower sump area. These have corroded
badly and is weeping oil into coolant passage as well.
Can anyone tell me if the GAS engine runs same sump?
If indeed do, this will increase my chances of finding a spare. Also, need the thermostat housing.

Thanks.
