Please provide the contact info for Northern - who are they? This is for case 446 hydro pump - correct. I tried at a stand still to put pressure on the lift and it done so very slowly. The brakes are not needed when I use just the loader. I will try this but that does not seem to be the problem. If anyone had evere remedied this I would appreciate some input. I already tried the control valve underneath. I'd also ensure that the brakes aren't dragging. If that's the case then you might disengage the pto and see if that improves power. The only think I can think of that might connect the two problems is if the pump/loader isn't connected right any it's always running against relief pressure load. I don't know if the tractor has always worked that way since you've had it. I don't know the tractor but it sounds like it has a HST and a pto pump for the loader. Does the new pump have a control valve too. In low it will work but not go up steep hills. //646/// It doesn't work in high gear in the rear. I would like to ask anybody to answer this for me. Well maybe since the tractor blower does most of the work the walk-behind already has a retirement home and is now reduced to arguing for space in the garage. I think it needs placement in a home for retired equipment. Even if I can find replacement fan shaft bearings, the engine compression tells me that I'd be throwing new drive parts in the face of an engine that's going to demand attention pretty soon. However, I might have to give up on an old snow blower. I tend to want to keep my old stuff going because patched up old stuff tends to out last new box store quality replacements.
CASE 446 HIDRIVE HYDRAULIC FILTER MANUALS
One alternative might be buying manuals and parts for a do it yourself try. I'd think in terms of what the alternatives cost. The shop tells me it's $300 labor to replace the seals.

I also own a 1988 446 Ingersoll with the seals out of the pump. If a relief valve is part of the new pump, you might think through an idea if the new pressures are appropriate for the old TX. Take care on that new speedy tractor and don't let it throw you. Low gear still has enough torque for any appliction. I actually replaced my 8 GPM pump with a 15 gpm. I found a direct replacement pump at Northern. New bushings would likely hold the gears further from a worn housing. High pressure forces the gears against the housing to create the seal.

I suspect that just replacing the bushings on an old pump may make its efficiency worst instead of better. probably are available or could be made by a machinist. I don't know if typical pumps on compacts use pressure plate seals for the gear to housing seal or if these are replaceable but that's a rebuild possibility.īushings, drive gears etc. Just replacing the gears on a old pump may not restore adequate performance. A rebuilding problem for gear pumps is that the seal between the housing and gears has to be close for the pump to withstand high pressures, but the housing wears over time. My pump is a gear type and that's the most common type used on compact tractors. People with older farm tractors do talk about having pumps rebuilt, and the success of a rebuild may depend on the problem and pump type.
CASE 446 HIDRIVE HYDRAULIC FILTER MANUAL
My Ford repair manual says the pumps aren't serviceable and the parts manual doesn't have part numbers for internal parts. I'm wondering why the pump needs rebuilding and what type pump it is? Finding a kit could be a problem. Your best bet is to buy a kit to rebuild the pump. Any help in this matter would be greatly aprieciated.
