630 triple range

I've been shopping for a 50 HP tractor and recently bought a 630 gas triple range drive. It has been painted and previous owner said the lower rear section of the hood is from a different tractor. This is a row crop, 36" rear tires and has the factory Eagle Claw hitch. I believe the SN plate is likely incorrect as far as Identifying the year of manufacture.
If previous owner is correct, concerning the hood being from a different tractor how can I identify the year of manufacture? It will need a tune up fluid changes ect. Where can tune up spec's &/ or a manual be obtained.
Thanks, Tom
 
Your 630 tractor was only made from 1960 to 1963. With out a serial number tag one can only guess at the year by the way the tractor is equipped. The one in the avatar to the left is a 1963 and has the power steering reservoir behind the grill, in front of the radiator. Earlier models had them on the front side of the motor. I've been to events and every other 630 was in some way factory different from mine. I wish I would have notated their years.
My manuals are Case reprints which I found by googling ji case 630 manuals.
Your motor, the 188ci is hard to find parts for, cylinder sleeves are non existent. So keeping good clean motor oil in it is important. Do oil your distributor at the top of the shaft and at the side oiler. Also your tach and speedometer cables need oiling.
Depending on where you live, ie. how cold does it get when you want to use it in the winter, lighter oil like 10w 40 if you live north of I 80 and 15w 40 south of it would work. Your hydraulic oil should be Case Hytran or equivalent from a farm store. Some people add some (a quart) of gear oil to help the triple range gears get good lubrication. The transmission/differential uses gear oil, again lighter north and heavier south.
I suggest contacting John Saeli 315-585-9826 as he may have most of what your asking for.
 
Tg has it covered about as well as it can be done. Pics may help, tractor front, back, both sides and dash area. I'll just add the starting serial nrs for the model years 1960-63 just in case you get it narrowed down. The gas, row-crop tractor in the 630 series is designated model 641. Manuals come up on ebay occasionally, very spendy.. Having triple range indicates a dry engine clutch and probably a hand clutch if it has a standard PTO so avoid COM only manuals. Do check with John, he's very experienced, pick his brain.

Thank you.
I won't be doing winter work with it. I've used Shell Rotella in my other tractors with good results. Tractor is stored inside until spring. I'll go through things when temperatures warm up. To lube the distributor shaft is there an oil port underneath the rotor?

Thanks for the information. It does have the hand clutch and PTO shaft appears to be standard size 1-3/8 inch. What is the difference between the standard PTO and a non standard PTO?
 
I am having trouble uploading pics and don't have time right now to figure it out. Try again tonight.

The 630 can have an independent PTO that has the hand clutch incorporated in the PTO unit. It is the same over-center clutch as the hand clutch you have in the torque tube (only smaller) and adjusts the same way.

630 has 2 standard PTO's listed as before and after tractor serial nr 8191147 (sometime in 1962).

This was in my notes: A total of 4,477 630s were built from 1960 to 1963 also all COM 630 were factory with IPTO don't know if that last is true.

(Pic 1 & 2) 630 IPTO parts view and a torque tube over-center hand clutch pic. Same clutch, but smaller, in the IPTO and eliminates the need for a torque tube hand clutch.

(Pic 3 & 4) 630 standard PTO's before and after tractor serial nr 8191147. You could somewhat narrow down the build year by pulling/measuring the drive shaft although it may not worth be the effort, pic 5 is a typical (530) standard PTO out for drive shaft seal replacement.

IMHO there is much more usable information in parts manuals than any service manual.

If you can't load pictures, maybe a discription of the dash would be good. Does it have amp,oil,temp,gas, tac and speedo under 1 glass?

I'll take some pics. Should be able to up load. Have been out of town for holidays. Look for something next week.
 
1960 & 1961 Tractors had Double Disc Brakes. 1962 is fuzzy, but definitely by 1963 CASE was using the Band Disc combination. Everything for your 188 Gas engine is available, including Sleeves, but not Pistons. Egge Machine in California has made Pistons for that engine.

Thanks John, the internals of engine sound good. It runs a little rough right now, suspect there is some old gas in tank. I added fresh gas plus a half bottle of Seafoam. The plugs look new, distributor cap is vintage , new points & condenser will be installed. Timing Check & adjustment if necessary. Should probably look at carb if ignition tuning does not work.
 
The reason I ask about dash is my 351 had those same size wheels and had the triple range, etc. The 500 was the same tractor with different tin. I think the 630 dash might be different than the other two. Some one else could chime in on that.
 
My 630 has a black face in the gauge cluster, otherwise it looks the same. As I restored it, I noted that there were no longer felt oilers on the tachometer and speedometer drives, just a hole to put a drop of oil in. The tachometer is driven via the generator unlike the 351 at the torque tube.

Hello everyone.
I'm posting some pictures of my 630 for identification of the model year. The SN on the tag is 8361648. As I said previously this may be from another tractor per information from the previous owner. From these pics does a model year jump out to anyone?
Tractor is shredded presently and we have recently 20 plus inches of snow recently so took pics inside & light was not ideal.

I've included a shot of the carb. Is this a Case carb? I think it's not as there are 3 ports for an incoming fuel line. I have not found a manufacturer identification on the bowl. What manufacturer & model were standard for the 630's?

Thanks everyone, anxious to hear from the group on identifying the year of manufacture.

630 factory carbs were either this Zenith or an M-S. If I get time i will try to sub those case p/n's with the mfr p/n's

The multiple fuel inlets on a tractor carb may have been for starting on gasoline for warmup and working on kerosene. There would be a small gas tank and a large kerosene tank. M-S & Zenith carbs were used extensively in early aircraft with multiple fuel tanks and possibly a carb priming circuit for tank changes.

Easier to view and ID components with upright pics.
I can't ID the year for you but there are people here with much more experience than I have.

Thanks Joe for rotating my pic's. I.m a novice at posting images appreciate you doing that.

Sometimes a casting date was cast on the bottom of the engine block, left side, just above the pan line. Also, if you give us a close up of the brake drum, we can narrow it down.
