| I'm looking to buy a junk 3630 and bring it back to life problem is I am setup on 36" rows and I want to make sure that it will adjust to 108" wheel width and straddle 3 rows before I get started anyone know if this is possible with these coupes? |
|
| |
|
Central Illinois | IIRC, those early series coupes were available in a 72" or 80" width. The 80" with axle extensions would go out to 120". Not sure what the 72" would go out to. |
|
| |
|
| Thanks for the information. I measured the width at 84" center tire to center tire. If it were an 80" model it would not have the ability to be set on 108" correct? |
|
| |
|
Redickville, Ont | I have 80" 3430 and 72" 3430. 80" is set for three rows potatoes so it's 108" on centre I'll see if it it will go wider but it's got to be close to max. The 72" is set at 72" so I'll have to do some measuring to see if it would work but can't see why not. As long as there's enough track on rear and enough holes in front axle. I'll post back tonight. |

|
Central Illinois | Other way around. An 80 would go to 120 Max so 108 should be OK. Not sure what a 72 inch machine would max out at. I think if you look at the serial number tag, it would either show 3630 ( standard 72 ) or 3630-80. |

| Thanks i really appreciate it. I was very disappointed when i realized it was wider than 72" center wheel to center wheel. It does have other holes on the front axle that i assume with line up somewhat with 108" or could be made to within reason but the rear was where i was mostly concerned. I just want to make sure it will straddle 3 rows at 36" spacing before i buy it. I am planning to buy it and replace the Peuguot with another engine and maybe change the transmission to auto if at all possible. How do you like yours? I would spray about 750 acres every two weeks. Big reason i want coupe or sprayer this size is to be able to pull it behind a dump truck with a nurse tank. Have you ever pulled yours? Sorry about the questions really appreciate the help |

|
| Ok i will find out what the serial number is. Thanks for the help |

Redickville, Ont | From what I can measure I'm pretty sure it will work. Also manual say you can but says something about axle and frame extensions. I know you need to lengthen the axle which is just pto shaft I did mine 80" when we move it to 108" wasn't a big deal but not sure what the frame extension are. I wonder if that is for 120". I'll look tomorrow in the parts manual see if it shows anything. If it's Hyd slide or manual slide you can always try moving it out see if got enough slide before you buy it. It not hard to move the rear ones especially the Hyd one just need to move the stop. Every hole front axle moves it 4" so one will line up. We love ours. Had one since 95 and bought second one for spare and nice not to have to do so much cleaning when your trying to spray grain and spuds at same time in spring and same when where using fungicide and killing potatoes in fall. The motor is gutless lol but you get use to it. If your switching motors because power we just switched injection system on 80" to a Bosch and I think it has double power now. Just needs two steel axle now and I could fly up road. You can put 400 gal tank on but if your in hills I've herd guys standing them up. You can't see out back then but can't see much anyways. We have pulled ours. Hard to hook up but if you modified hitch so it had slide like wagon would fix that problem. What we did is put hitch on sprayer to tow 1000 gal nurse tank. I like that much better than dump truck. You can set right out onto the wagon. Local coop pulled there all time hit you need right tires or you'll melt them off. We spray 200 at spuds every 6-10 days depending on if weather is good. You can do it in a day if things work out good. One thing I'll suggest they don't turn good. On 72" machine we got pieces made to make it turn tighter. You don't special ones if your wider cause they don't hit. You just need to drill hole in plate I think a inch back to make it turn. Forgot to take picture of it I have it sitting beside the drill press cause it's driving me nuts not being able to turn. Have anymore questions just ask.

Central Illinois | The frame extensions bolt up to the front axle . It adds 6 inches to each side:

| Sorry would have responded last night but the hurricane knocked out the Internet and we just now got it back up. We ended up with five inches of rain and not much wind so we count that as a win. Thanks for the measurements. The engine has not ran in years and the mechanic who last worked on it said he thought the block may have been cracked so I plan on swapping it. I saw a coupe on this site that had a 350 gas engine and a 350 turbo transmission so I figure I can make something work haha. The booms have been destroyed so I will have to replace them. I will probably try and run semi truck tires on the front I have a set on our 4450 Jd now. Does yours have the T5 transmission? How reliable has it been if you do? Do you have any idea what the rear end ratio is? I assume that there is some reduction at the wheel |
|

|
Redickville, Ont | Haven't forgot about you. I'm looking for article I seen on here one time about guy switching ratios in rear end after he repowered it with cummins. I printed it of but can't find it in shop. I'll let you know if I find it but our 5 speed never been touched. |
|
| |
|
Central Illinois | My 4455 uses a Dana 44 center section so common ring & pinion sets will work. IIRC, the 3430 had a 4.11 ratio Dana 35 and with the Cummins conversion switched to a 3.07 ratio. |
|
| |
|
Redickville, Ont | Oh it must be your thread I read. I really like a road gear it's so slow on road with our narrow tires. We should just put bigger tires on next time. |
|

|
| Thanks for the replies I managed to buy the coupe for 2 grand.

| Thanks for the gear ratio info. So the cummins had that much more hp or turned more rpms? I know it's not normal but I'm leaning toward using a 6.2 diesel and 400 turbo but not ruling out a Perkins or cummins. Regardless of engine I'm 97% sure I'm going to swap to an automatic. Thought I had found a deal on a 4bt with Allison on eBay but I think the guy is a scam from what few reviews I have read. He was out of Ohio |
|
| |
|
Central Illinois | Other way around. IIRC, the Peugoet ran 3500-3600 RPM. The Cummins only turned 1900-2000. |
|
| |
|
| Yea sorry stupid question there. Did you keep the manual transmission and adapt it to the cummins or did you change transmissions? |
|
| |
|
Central Illinois | Never did the conversion, just did a lot of research on it. I put a new replacement Peugeot engine in with a little larger Turbo from a USA company that ended up marketing replacement kits for Spra-Coupe. Many an acre has been sprayed over the years with that "gut-less" French motor. Just have to be a better operator. |

NW KS/ SC ID | Shanrock,
What ever became of the Spra-Coupe? What motor did you put in? |
|
| |
|
| Sorry to just now respond. The spra coupe is hopefully about to make its maiden voyage tomorrow. It has been a hell of a project. The engine is a 93-94 international 7.3 idi - non turbo pre Powerstroke. It has a c6 Ford transmission and a np 435 transfer case behind that. I regeared to 3.08 with a spartan locker in the Dana 44. Going from the 87 hp frenchy diesel to the 175 ish hp 7.3 with twice the torque is almost too much ha it’s hard to stop the machine even at idle. I run a belt driven hydraulic pump for the booms and the original power steering pump drives the steering on the coupe. |

|
NW KS/ SC ID | how much frame modification was required?
I was wondering about a 3800 GM car engine or a 4.3L GM pickup engine in one.
I found a 3630 with a bad motor for 5K, and was pondering how good of a deal it was. I might just buy a good 220 or 230 Coupe instead. |
|

|
| Had I not came across the 7.3 the 4.3 / 4l60 was going to be what I was looking for. The 7.3 fits fine between the frame but the frame was lengthened 20 inches or so. The c6 actually bolted in where the t5 cross member was and then adjusted the motor brackets to fit. There is a guy in Kansas who gave me this idea. He runs a 350 engine 350 transmission setup. He still uses it to this day. Depends on how the rest of the machine is but 5 k sounds steep. I gave 2 k for mine but it needed a good bit of work and I have got away from almost every spray component of the coupe just for ease of parts availablilty and price. The 4.3/4l was I had thought a great combo. The c6 limited me to just the 1:1 od ratio so I had to lower the rear ratio from 5.89 ish to 3.08 so it would run 20 plus down the highway. With the 4l you would keep the od and with the gas engine have the rpms to move on down the highway. The frenchy diesel screamed and would run 3000-3500 . The 4.3 auto trans or manual was I thought a great option. I don’t know what all you intend on spraying but I don’t think a 220 or 230 are nearly the machine you can make the 3630 |
|
| |
|
NW KS/ SC ID | Total acres to spray could be done with a small 3pt unit if I had enough time, so going after a self propelled unit is overkill to begin with, so I dont need much of a SP. :)
Though we already have a tender truck and a single axle trailer specifically built for 4 wheel Coupes, so in a way I am justifying an auction purchase with perhaps another auction purchase. :) |

|
| Sorry to bring back an older thread, but I see LOTS of talk about swapping different engines into the 3630 coupes.
What I want to know is what's being done with all these perfectly good Peugeot engines? I might need a cylinder head from one for mine. I'm in Nebraska, we don't have hills, and I have little enough acreage that I will probably only fill it to 200 gallons at a time. I have no interest in swapping in anything else unless the block is bad.
Thanks!
