Sunset/White 70 series ?

Were there mechanical differences between the 2 colors or basically "cosmetic? Thanks

I am not sure what the serial number break was, but the later power shift transmissions can be pulled from the front with a simple split at the bell housing. The earlier ones need to have the control valve pulled, transmission cover pulled, and bolts removed from the rear to get the power shift out. Internal parts are the same as far as I know.

I think the earlier was a snap ring or something in the rear that needed totally disassembled to get to, and later was deleted. That is all I remember but I believe the seals in the later got better too. Those tractor powershifts were basically notorious for failing in the 3500 hour range in our area from the mechanic and dealership. Then the limiter clutch... Oh yes.. the limiter clutch.

Did the cabs get improved noise insulation as quieter AC and JD cabs came on the market or did they stay the same throughout the 70 series production?

I get 10 to 15K on them here,, unless you run it like moron and stomp on the clutch without shifting them back manually to 1st,, this makes them shift three times all at once,, or throw away the relief cartridges they last almost for ever,, I have a dozen of them here all with 7 to 12K on them and never been apart that work just fine, a torque limiter runs 4 -5 k again unless you are being stupid,, I still know where many of them we sold new are at today in the same familys,, 99% of them i have worked on were all operator error

it is small row crop work here. allirrigated. At the end of the field, everytime, the tractor will be clutched, down shifted, reversed, turn direction around and then back up. This is for planting, cultivation, haying, and tillage. We do a lotof tillage. disc, mold board plow, work down,land plane, so a lot of clutch and forward and reverse. I have seen several rps34 that had less than 5000 hours with a piece as big as my fist bused from the carrier because of the bolts clamping it together. Every time the clutch pedal is depressed, the engine surges and that surge is the planetary going from one direction to another. Some of my family is from texas, kansas and nebraska. Those fields are NOTHING like farming irrigated acreages in the mountain valleys here in colorado. Absolutely nothing like it. Ifyou have never came here and bounced over our water marks for a year and seen it and done it and actually DO it... I strongly suggest you do becauseyou will see 500 clutch/forward/reverse/ operations per day, a lot being at PTO rpm in order to maintain vacuum planter function or pinto bean lifter/windrower operation or onion harvester air velocity. Come on over and we can put you to work. I bet we will see just who looks stupid. It was a common recommendation here no to depress clutch while engine is at high rpm, well in these conditions here is no choice.

they probably last forever if you stab it into one gear and pull it there all day in a huge field. but get to the end, shift from 2 or 3 to 1, lift your implement, then reverse and turn then back forward to line up the rows then stop and reverse to the headlands then stop, start forward and drop implement then shift to work gear. I just mowed cornstalks for 2 days on allpoint row fields, EVERY TIME top and bottom was raise mower, reverse, turn, forward, reverse to headlands, back forward, drop mower and all at pto rpm to keep mower from pluging and shearing pins. the case rps34 would fly apart here. even the manual recommends against this type of operation. What choice is there?? You either have to make livestock feed and possibly sacrifice tractor or just quit altogether I guess.

I love the tractors to death and the looks and the torque that engine develops, and the more roomier cab than the soundguard, but they have proven to be unreliable here. Unfortunately the masseys and johndeeres could run forever on the quad range or that multipower and literally never die, just go and go and go, and no matter who ran them, or how they shifted them, those transmissions did not have the failure rate that the rps34 powershift or limiter clutch had. We have NEVER killed a john deere or massey. And have killed a 970 powershift, a 1070 powershift, and a 1370powershift. Have ran john deere quadranges to hours un believable possibly 15000 but tachs break, get replaced, and really lose track after so long. The dairy farms killed the rps34,we killed the rps34,the old case dealer killed a few of his rps34s and a big onion farmer killed a 1570 rps34 and a few small family opeartions killed a few 2290s and a fruit orchard was selling a tan 1070 a few years ago. I went looking and rps34 was out. I saw with my own eyes the tractor shop dismantled a big like 2470 or something (case mechanic since he was 17 and that was about 1978) and he showed me a busted carrier that was toally ruined. bug piece of it was broken out around bolt holes, like c2 carrier or something. He showed me a numerical stamping on he carrier that he said pertained to a part from like 198xxx month/year manufacture. He said that the carrier was definitely changed because the date was NEWER than the tractor, meaning that this tractor destroyed first component, ran a few years, and damaged another component then now is being worked over for yet another repair, maybe even a forth in there somewhere. That is not that good for a not too old tractor. and if everyone lasted 10000+ hours that tractor would have 30000+ hours on it. I highly doubt
that.

And furhermore, I need no clarification on this. Walk through a tractor salvage yard and look at the rps34 case tractors. The power shift parts are the first thing gone from all of them, they just gut the transmission and sell he rest later. The engine won't die, and the rear end usually outlasts the chassy, but the rps34 gets gutted first. Call that tractor salvage yard in western nebraska and ask hoe many case injector pumps they have then ask how many case rps34s hey have. let me know how hat goes. Bottom line, You saying that you never saw it happen does not mean it is impossible or even improbable, me seeing i happen my entire life and countless times means that it is a viable concern.

WOW!
