I picked up a 1960 Case 630 Diesel. Just wondering if there were many of the 630 Diesels made? This one is a triple range. Thanks - Bob
 
I have only ever seen pictures of a 630 Case, every other model has shown up over the years in my area. Both gas and diesel models as well as 530 and 830 Case-O-Matic tractors surface from time to time, but not a single 630. My understanding is they were only made for a short time, and being to close in hp to the smaller 530, and the only slightly larger 730. Closer in build to the 530 and 430, with transmission and pto while the 730 and 830 were more similar and could shar transmission pto hydraulic parts. Maybe not a rare tractor, but certainly not a common tractor either. I am sure you will enjoy your 630 diesel
 
Hi Bob:

My Dad bought a new 630 diesel in, as I recall 1963 or 1964. He used this as his only tractor until about 1975 when he also acquired a 730 for a bit and then an 830 which was later traded about 1978 or so for an 870 with power shift. The 630, 730 and 830 were all Case-O-Matic and were very good, trouble free tractors. Dad was a big fan of the Case-O-Matic drive system which he thought was ideal for many farm tasks (at least on his farm). I can't say I disagree with his assessment (I spent a few hours on these tractors), but I might be biased! The 630 was run summer (farming and haying) and winter feeding cattle)in north-central Saskatchewan where it does get pretty cold in the winter. The 630 started reliably in temperatures as cold as -40 degrees provided the circulating block heater was kept plugged in. It was run pretty much everyday over it's working life and was also a bit overworked at least some of that time. The only repairs I remember was a starter switch which on our particular tractor (not sure if this was how they were all made) was in the top of the transmission case (neutral start) and a broken push rod which was fished out of the oil pan and when one wasn't readily available from Case got brazed back together and when the tractor was sold in 1998 was still in the engine with the new one with the Case parts tag attached was still in dad's tool box. Other than those repairs nothing else was touched - it never had the heads off, but dad was very regular with oil and fluid changes which make all the difference with diesel engines. I'm not sure of the hours as it spent a good part of it's life with a broken hour meter but I would guess well over 10,000 hours. According to tractor data Case built 1181 of the 630 models between 1960 and 1963. Thanks for the opportunity to reminisce a bit about a previous life.

Cheers and stay well.

Thanks For the story on 630 and C-o-matics ,,.. I like My 800 for the novelty , but not sure about having them all that way ,,1191 is not very many built , Which Explains Bruces Comment .i have had one 630 gasser that did OK power wise. And I have seen about 4 others in these parts over the years ..The 188 diesel was in the 430-530-630 , 430 had a smaller capacity radiator and turned a few revs less than the 530 and 630 , since all my 430s have had previous owners and lives i have made repairs . But vI only have to repair something ONE TIME . It stays fixed and NEVER wears out again on My Farm .. anytime my pumps are rebuilt on the 430s i ask Jeff to turn them up to 530 specs
 
Bob, I'm from the state just north of You-bought a 730 gas COM from You 3-4 years ago. I have a 630 diesel COM, just completely restored it from radiator cap to drawbar. Bought it used in 1978. Does yours have a serial tag? Mine has NEVER had one and the casting numbers have been ground off. No way to tell when it it was made. Great tractor. There is a story about the 630 why so few made and number removal, but can't get any Case men to tell about it. Do You know anything about it?
 
The 630 was advertised as a 4 plow tractor and that would be really pushing the boundaries of its design. The 730 was also advertised as a 4 plow with a much heavier driveline and bigger engine. The 630 was not a big seller, kind of an orphan, so Case dropped it. I have a gasser and really like it, but would never hook a 4 bottom plow to it and work it hard. Don
 
As CASE dealers back when the 630's came out, we sold a good number of them. The 630's with the G188 engines were bullet proof. The early 188 diesels with the narrow flange sleeves had cooling and head gasket problems. The cooling problem was cured by drilling a 3/16" hole in the 7/16" cap screw behind the water pump that secures the timing cover to the head. Case engineering came out with multiple thickness fire ring styled head gaskets to control combustion leaks, with mixed results. Later they designed a wider flange on the top of the sleeves to increase the sealing surface around the cylinder.
Case had pushed the design of the original 188 to it's limits, and the model aquired a reputation for being troublesome.
The 630 replaced both the 5 and 611B tractors which featured 36" rear tires on the row-crop models. They had lots of power and traction and filled a big gap in the CASE lineup between the Rock Island series of tractors and bigger heavier Racine built tractors of the time, but CASE engineering was never able to truely fill that gap, and dropped the 630's from the lineup. In 1970 the 70 series was introduced and the 770 was ment to fill the 60HP gap, but it was underpowered, too big, and heavy to be a contender in the 60+ HP market.
CASE Corp. finally solved the gap problem with the acquisition of David Brown.

Sorry Bob didn't mean to get in middle of your post. Thanks to AGC & Rudolph for the information provided.
 
Mine does have the serial tag. 8168xx I am thinking. I also wondered if the triple range would be more prevelant or the COM? I remember the 730. Take care - Bob
 
I always thought that the 630 didn't sell that well because it was more expensive that the 430 or 530, yet the 430 or 530 diesel could be tuned up to the same HP. That said, I do like the larger tires on my 630 when I use it, though not so much when it is time to replace them.
 
Thanks for that information. Do you happen to know the approximate time intervals covered by the various engine modifications? All I know is that my dad's was bought near the end of production judging by the years the 630 was built. It might have even been a carryover from the previous year. His was a real workhorse and very reliable over the years it was used as our principle farm tractor. One other thing I recall is that unlike the 630 I've seen pictured it had wide fenders covering the whole width of the rear tires. These were painted red (Flambeau Red?) I do recall that dad did have his 630 dyno'd and as far as I can recollect it came in at 54 hp on the PTO (early morning in dense air) so not too shabby since they were rated at 48 on the PTO at least on TractorData.com. I also remembered one other issue that he had to have fixed and that was the seals in the fuel pump. Our 630 had a very different fuel pump than say the 730 or 830 - I'm going to say "RusaMaster" sp. or something like that as opposed to a Bosch pump. Does this ring any bells for anybody?

Cheers and stay well.

I think I have four or five of them around here somewhere. I really should thin the herd. All of them are triple range. Neighbor has one with COM. Depending which one you look at, there's three different power steering designs on them depending on the year.
 
Have had a 630 com diesel since the early 80s. Use to grind all the feed and square bale all the hay, alfalfa and brome. Pulled a 8 pack skid behind the 24T JD baler and the 630 had a trail of diesel smoke all afternoon.
