Need help figuring out what this motor is......

[mx842]

I've been collecting parts to build a wood processor for a long time. I've come across several motors and pumps that I figured I could use for one part of the build or another. I was at an auction last week and they put up a junk with all sorts of stuff packed in it and at the bottom of the box I saw what looked like a big ol hyd pump or motor and what looked like a great big saw bar. They wouldn't let you dig into the box to see what was inside but I figured what the heck. They started out at $150.00 and no one took the bait so after a bunch of pleading from the fast talking auctioneer they started to close out the box and move on but I yelled out 50 bucks!!! The guys on the stage looked at each other and as one of them scratched his butt with a puzzled look on his face the other guy yelled out SOLD!! to the guy in the second row with the camo hat on.

I turned in my tickets for the stuff I had bought and as I backed up to the door the guy that was loading the stuff told me, MAN you got a deal with that box of stuff there. He said that he had planned on bidding on it but they had called that box while he was in the out house. Anyway he offered me $100 bucks for the box and I may have taken it if he had not already told me how good of a deal I had gotten so I said nawh I'll just take it home with me.

I pulled away but I just had to look inside to see what was in the box so I pulled over to the side and started digging. That same guy came over and said how's about $150 before you go digging? But by then I had already grabbed a hold of that big old 404 bar and under it was the chain to go with it along with the sprocket and a bunch of other related parts. I said sorry but the cat's out of the bag and that I had been looking for this kind of stuff for a long time. He then told me that the parts had come off an old delimber cut off saw that had come loose from the tractor and had gone off the side of the road and down an embankment. He said the insurance company had bought it but never came to pick it up and after several months the storage was more that they wanted to pay so they gave it to the shop owner as scrap.

Anyway long story short they stripped it out and scrapped what was no good and had had the parts on the shelf for several years and finally the old guy died and they were auctioning off what was left. When I got home I found this big saw motor. It's a Parker and there was a tag on it that I could make out PT# 400391. There was some other numbers on the tag but I couldn't make out everything. Also there was a number stamped in the case of the motor that was 3035020002 and another number on the tag that I believe was 303 9310343 There was also 045 stamped in the face of the flange where it bolted up. It is round in shape and has a 2 bolt flange. It's pretty big probably 12" long and about 8" round in size and I can measure it closer if that would do any good.

I have searched all over and none of these numbers comes up anywhere and when I searched the parker site I still didn't see anything that I could say was a match. I think it's a gear pump but I'm not sure.

The saw blade and chain looks like it was just changed out and had very little use on it. The sprocket had some wear but still usable and I believe I could weld up the drive marks and make it like new without much time involved. Looking at it though it would probably last me a lifetime doing the little work it will have to do while I have it.

I'm trying to figure out what kind of motor I would need to drive such a thing as this. That will be the next item I will be trying to run down.

When I did a search for parker hydraulics PT# 40039, links popped up referring to a f12 hydraulic motor. I dont know if thats is what you have, but if it is you have a very expensive high speed hydraulic motor. These motors are pretty common on forestry havester saws like the item you described. Your best bet is to call Parker and find out a little more about hydraulic requirements for this motor. Depending on just how big a processor you plan on building, this could be a very good saw motor, or a very expensive part that might cost you more to power than what you would want to spend. The 3035020002 number might suggest a F12-30, but here are the part numbers I found for a F12-30's, and your numbers dont match any of these

And to add, it you decide you cant use it, I am interested in purchaseing it

Thanks a million.....I searched for 2 days and never came up with anything, I even moved numbers around in case I wrote something down wrong but I never thought about dropping the last digit. I will look at these links you gave and see if they lead me anywhere. Thanks again.....

I pugged in the 303 number and this turned up. https://warehousetwo.com/wm/190/1669/303-9310-343+COM. it lists a phone number in WV you can call and maybe find out some more information. Discription says gear pump

Dang!!! I have two computers that I could post a pic from but one needs a mother board before I can get it fired back up and this one is so slow right now because it needs more memory that it wont let me do much more than start it up and peck around on the internet.

I found a motor that is similar on e-bay. This one has a 1" shaft, the one on the motor I have is 11/4". This one has a 4 bolt flange mine has a 2 bolt flange. I can't tell if this one has a fitting in the collar between the flange and the pump body but the one I have has. This fitting was used to oil the chain I believe

Notice the shaft does not come out of the center it is off set the same way as mine. I don't know if that is considered a bent axis motor or not but from what I have looked at on the parker site it looks like the f11 and f12 motors are bent axis motors but nothing I saw there look the same as this motor or the one I have.

Mine has a plug in the side of the frame body just like the one on e-bay, mine also has the work ports in the back of the body just like the one on pictured there. Notice, it has 4 large bolts holding the unit together just like the one I have.

Nawh this one is nowhere like that one. I tried to call that place you posted the link to yesterday and someone was supposed to call me back but I'm not really looking to hear from anyone cause the guy on the phone I talked to didn't seem to interested in my problem.

From your link, I can only guess that what you have isnot a f12. I would not let that discourage you from using the motor as a saw motor. You need to find out what you have first before starting the build. While some folks use small cuin motors and run high rpms to power their hydraulic saws. Lots of manufactures will use gear motors in the place of the more expensive F11-f12 parker motors. I dont have the exact numbers in front of me right now so I am just talking off the top of my head, but. A 2cuin motor with 30gpm at 2500psi, will give you a rpms of around 3800rpms and 20-25hp. Couple that motor to a 13tooth 404 sprocket and you can get a chain speed of close to 6000ftmin. This is close to the recommended speed for a 404 chain and about 3 times the hp of a 3120 husquvarna chain saw. A set up such as described will give you a very fast cutting saw for your firewood processor. Problem is it will take about 51 hp to power your saw Engine hp is one reason some folks choose the smaller hyd motors and higher rpms for their saws. In other words, the motor you have might not be for everybody, but is doable if you have the parts to make it work just laying around. Before doing anything, you need to talk directly to Parker and find out what you have. It may be that you need to sell the motor you have and look for one a little easier to adapt for your purpose. I am no longer interested in purchasing the motor as it is not what I hoped it was.

Another problem with your motor is shaft size, it is going to be very hard to find a 1 1/4 bushing for a chain saw sprocket. I think the sprocket without the bushing is less than 1 1/4 bore.

I thought I had corrected the 404 part. It is a 3/4 drive setup. I have the bushings and the gear drive. The one that they were running was a 9 tooth sprocket. After looking at them they are not in as good a shape as I thought but they don't look all that hard to make if I can access someone with a CNC plasma cutter. I know several people that have them so maybe I could work something out.

I called Parker and they transferred me to someone else and I left a message. Hopefully they will call me back.

Well I finally got in touch with Parker. I don't know what happened the first time I called but I went the e-mail route and a nice fellow got in touch with me and sent me some information on the motor I have. This is a motor that was made by a company that Parker bought a few years ago. The company was Commercial intertech.

I gave him the 303 9310 343 number and he came right back and said it's a 25X, fixed displacement motor with a 11/2 inch gear. Evidently these motors were widely use as saw motors in the 90's because the first thing he asked was,........was it on a piece of forestry equipment and used as a saw motor? When I told him yes he told me that these were use by most of the equipment manufacturing companies back then and probably why Parker bought the company so they could sell more of their F series saw units.

Anyway he sent me some information on the motor, now I just have to figure out what it all means. This is a link to a pdf file with the information on the motor. Hopefully someone can help me figure out what this all means but just me looking at it, it looks like I will need more HP than I have right now on hand.
