Does anyone have a good source for information on the different BeGe hydraulic system and parts? Common add on hydraulic systems for Cat and others during the 30’s through 60’s?  Lots of different setups out there and I have several different ones. I thought I remembered seeing a summary of the different pump sizes and their applications but I did not find it searching on here. Picked up an older oval tank one for a D6 but have several newer rectangular tank versions also. I see lots of differences now that I am looking at mine, different tanks, different valves and some have filters. Thinking the ones with filters are the newest. These are all rear mount systems but I think I have seen engine driven pumps also. Just wondering what was out there, thanks, Mike 

This is from member Jack Alexander’s book.
An interesting one that provides a bit of insight on the BeGe company and their products.
Not sure if Associated Tractor from Stockton, CA has any literature on the various models; they bought out the rights to BeGe years ago and is the main source for new/used pumps and parts.
Bought several of these to share with friends/members.
PM me your mail address and grumpy me can send you one if you like. JM

Mike The 650 wide body was for RD6s. D7s and 8s slow runners carryall scraper and ripper pumps if you put one of these on a 9U it will boil the oil I learned that the hard way, the narrow body 850 works on 9Us faster running I think about the same GPM. For farm work the 1000 was pretty popular and I have seen it on both 6s and 7s ,they made a 1400 smaller pump I had one of these on a Farmall M for 40 years NO trouble was fast, real nice on a planter and bean cutter, my uncle had one mounted on the belt pulley drive on an OS6 to work peaches. I have seen a BE-GE rotary valve used with a belly pump on a Farmall M they were way too slow, all of these older pumps were 850 lb. if you tried to set the bypass up you will blow the seal I learned that one the hard way too. The later PR220 pump was 1600 lb I have one on the 7 I love it, we just re sealed the pump in October have not used it since I bought it used in 1985 and it’s never caused much trouble. BE-GE was in Gilroy ca. at one time they built Carryall Scrapers. Drag Scrapers and their Scraperplane which was their version of a land plane I have pulled them ,they were no 60 foot Marvin but a lot better than a drag scraper and with caster wheels were easy to turn, if you need parts call Associated Tractor on Charter Way in Stockton they have been real good on parts. I have a couple of 850 pumps that I will probable never use if somebody needs one. 17afarmer. Mike

  Here is an AC with the BE-GE pump, somewhere I have some pictures of an IH O-4 with the same setup, in fact many of Orchard wheel tractors of that era had these pumps in this part of the world. Our 1960’s era Benner Nawman Tomato Harvestor had multi unit Be-Ge pumps and some of the high speed hydraulic motors were from Be-Ge as well as well as the Be-Ge hydrostatic “clutch”

Way cool CR... Never seen a side mounted unit. It works, it stays? LOL. The coolest, but very warm one was on a tailseat machine owned by Dave Starn. The entire unit took the place of a seat base for a D2/D4. Some said they could get very toasty. Imagine sitting above that warm reservoir all day. JM
***Mike S., I dropped a copy of the book in the mail box today. Enjoy. JM***

17A: I have an 8U with an oval tank 850? Mine got super hot while ripping an olive orchard, but I thought it was because the vent was plugged and it could not breathe. It came with in on the machine, and I have seen plenty of other 8U/9U machines with the same unit. Needless to say, I either swapped caps or cleaned that one out and never had the chance to see if it cured the over heating issue. Oil got hot and had no place to go, it was pressurizing the unit. I thought it was ruined, but works just fine. JM

Juiceman I have seen the same setup on an IH o-4, Case LA, John Deere I believe it was a D model. That was the first time I had seen on this on a tractor that wasn’t used for orchard work. That tailseat hydraulic unit was kind of neat as I recall seeing the picture on here before. Just the thing for keeping you warm when putting on dormant sprays while lost in the valley tule fog, probably the worst place to be come July, still a step ahead of sitting above a pto driveline.

I have seen all the common Be-Ge pumps mount on the front of crawlers to give live power. Several where in Hydreco systems with just the BeGe pump. So assuming BeGe was cheaper, easier. or fast to get than rebuilding the Hydreco pump. I have a very nice BeGe 2 valve control and tank fender mounted on a 9u with cheap Surplus Center vane pump about 15 GPM in 1600 to 2000 PSI so the smaller rams most equipment has any more work well. Yes a completely different type valve than they used on any pump valve combination units for the back of a Cat.

I have had both 650 and 850 pumps on the back of 9u's and never blown one YET. I have seen the 1000 series pumps on the back of 9u's that have expanded the tank a whole lot. But never had the history to know how the damage was done. The first time I was very surprised, how well the pump worked.

In the good old days of wondering the Myers-Ward yard in Fresno you could find BeGe's mount on many different wheel tractors. I think many MM had a mount and on the rear PTO the same as crawlers.

I have seen those BE-GE mountings on the back of Case LAs the 500 diesel was the same I know of one I am pretty sure is still around, they could pull 4 yard maybe? 5 yard carryalls with them my dad bought a Be-Ge drag scraper right after the War and they mounted a little Be-Ge pump on an SC Case, sure beat 4 mules and a Fresno and if I am remembering right 1957 was the last time the mules and the Fresno was ever used. regarding a 650 on a 9U the 850 I had on the D6 got a problem and I jerked the 650 that was on a 3 cylinder D6 I had at the time off and stuck it on the 6 cylinder and in not to long it got hot! and had run fine on the 3 cylinder long story short the 850 got fixed quick. 17a

I don’t think the issue here is the difference between the 850 and 650 pump, rather that you took a pump for argument sake produced 20 gpm at 900 rpm and put it on a tractor that was spinning at 1800 rpm now you are going to be cycling and trying to draw in 40 Gpm through that same system. The real numbers are a little different but same idea.
