ericj 1,576 #1 Posted July 1, 2017 I bought an Ark 550 loader at the big show. It supposed to have been removed from a D250. The sub frame that came with it would work with modifications but someone, who will remain anonymous for now has a sub frame from off a D200 and offered it to me for more then a reasonable price. picking it up in the Saturday am. So the last piece of the puzzle I need to make it work would be hooking the pump up to the front pto on my D. i would like to kindly ask anyone with a loader on a D series tractor for a picture of the pump connection. Mine has what looks like a love-joy connection disc, but the tractor part is missing. I need to go from the front pto shaft to a love-joy connections and not sure what is available to make this happen. Is the pto in the D series a special size since it rated at what 2000 rpm's. any info and picture would sure be appreciated. thanks eric j p.s. the loader is 20 miles away at a friends house at this time and he is away for the weekend camping Share this post Link to post Share on other sites
pfrederi 17,147 #2 Posted July 1, 2017 The pump on D200's is mounted on a moveable (pivoting) plate down low in the front. No lovejoy just a pulley and belt to the PTO. Hard to get a good picture for you. The bigger pulley in the pictures is my rear PTO. The pump belt runs very closely in front of it. 1 Share this post Link to post Share on other sites
pfrederi 17,147 #3 Posted July 1, 2017 Some more pics..sorry they aren't easy to see but like all Ds it is hard to get a clear shot of anything they aren't easy to work on. 2 Share this post Link to post Share on other sites
ericj 1,576 #4 Posted July 1, 2017 THANK YOU SO VERY MUCH that is exactly what I needed to see, I thought it attached to the pto. so I can add a pulley to my pump and make it work, again thank you very much. I hoped somebody would come through like this and you did eric j Share this post Link to post Share on other sites
pfrederi 17,147 #5 Posted July 1, 2017 (edited) I will try to get her up the shop in the next couple of days and drop the shield. That will give you a much clearer picture of what goes on. irony is I only put the shield back on a few months ago. Ran it without it for several years.

ericj 1,576 #6 Posted July 1, 2017 one more thing I would like to know is the diameter of the pulley in the pump. I appreciate all of your help and the pictures. eric j Share this post Link to post Share on other sites

I appreciate all of your help and the pictures. eric j The pulley is 5" outside edge to edge. Here are more shots. you will need the two end plates (L shaped) one has a single tab that acts as a pivot point for the pump mounting plate. the other end plate has two tabs creating a slot the pump plate moves in as you tension the belt. The vertical bolt on the right side (pic 1 and 3) is the tensioner. Pic 4 is the cover plate. Mounts tot eh bottom of the side plates the bigger hole give yo access to the tensioner bolt (this view is the bottom of the plate. I will leave the cover plat off for a few days if you need other pictures 2 Share this post Link to post Share on other sites
DavidP 9 #8 Posted August 9, 2019 Is there a part number on that pump? I have what looks like a log splitter pump on mine that I just picked up. What is the fluid type used in these loaders (ark 550). I have a leaking line and the guy I bought it from was topping off with hydraulic oil. Share this post Link to post Share on other sites
