lets see here..........

 

 
i had this stuff made at a machine shop for the front cradle on my 666. the center will be the same parts plus brass washers and some shims.

 

 
see that bright yellow canister on the right side peeking from behind the air breather? thats the trans filter. my 666 has a spin on but its in the same location.

i may have specs some where on the pins and bushings. those are repair weldments in the pic, the bushing is a spherical bearing.

Thanks! I'll look again this Friday. The filter must be in a return line of some sort right. Wondering if it can be restricting flow to or from the cooler? The pins n bushing look easy enough for me to make. The spherical eye I'll hAve to order.  The pump I see on the left rear of the torque converter is the hydraulic pump right? I noticed on mine the suction hose is not as it should be. Thanks again. Wish you were closer I could help you with the machining

thats the tranmission charge pump, the lower right is the hydro pump for steering and blade. it is always bigger than the charge pump.
yes the filter could be restricting flow. i have numbers some where for the major brand bearings, ebay or a bearing house is cheapest route, but i like name brand ones.

i wish you was closer to, i got charged pretty good for what you see there. pins, 1-3/4" drill rod, weldments are just iron like the frame, nothing moves in those.

Pretty sure my Skidder has had the filter removed Treeslayer. Is the filter in the line coming off the right side of the oil cooler? I can see a bracket where something once was near the right end of the air cleaner but on the motor. Thinking I can put one back on if it simple is in line on the right oil cooler line? What's the hex chrome looking thing in the bottom left of the tranny just behind the left step? Theres a small opening there.

This is where I think you say the tranny filter would be.

I also see to pumps. The one with the funny looking suction hose ( right one) is the hydraulic pump right? What does the left pump run?

There it is,  the transmission suction hose.  Looks like a radiator hose( at least from here) should have suction hose and suction hose clamps.  Edit. Just looked back at the picture,  to tell for sure which is which just see where the suction hose comes from.  I think the smaller pump on the right will be your transmission pump.

if i'm right, that rad looking hose goes to the hydro tank to the left and if so is the steering pump. this being the case, it looks like the charge pump on the left has been replaced.

vatkins, your filter is missing. yes it goes in line with the cooler line, i think to the converter. i would have to look to be sure. if you get a filter housing, you need to verify specs for flow and bypass. charge pump pressurizes the trans and fills the converter.

Morning,  new to the site.  Do you know what the plugs are on the side of the diffs?  Manual says screw with a nut at the end. Thanks.
