H Stuff

Here's the deal. First ol' Harley '83 was good enough to sell me this pump and I wanna take just a minute to let you know just how honest this guy is. Thanks, Allen!

But, now I'm really dumb!

I think it was Brian in NY who warned me that this thing will peel the teeth off the timing gear if I just install it on a straight H without first changing all the other gears in the front cover. Can someone tell me why this is or why this would be?

I don't wanna ruin my tractor, but I don't wanna yank that front cover either. How come I can't just slap 'er in there?

Thanks Guys,

Allan

To do this correctly for longevity, you will change out the front cover and gears with that of a 300. Everything else is the same.

I guess a fellow could run it until it quits then replace the broken pieces and hope that too many of the fines didn’t find their way into the crank and cam bearings.

If it was me, I would replace the cover and gears and forget about the belly pump and use the live pump for everything. You will have a much more useful tractor with live hydraulics on the loader.

Remember, all this is my limited opinion anyway.

Do you think that this type of pump can handle a loader? Didn't know that they were big enough for something like that??

Thanks,

Allan

I appreciate you help and bear with me here, 'cause I'm dumbern' a 12" Cresent wrench and a pair of Vice-Grips.

All I want to run with this thing is a Char-Lynn power steering motor; that's it. Just in, thru and out of that little control/motor and then dump back to the can.

Would this work and/or do I have to rig a pressure control/bypass valve to make it work?

I know people use automotive pumps, but they already have the pressure relief built in to the pump.

Can ya help me one more time and give me your opinion?

Thanks,

Allan

To answer the question directly, I don't think you want a low pressure relief on your steering circuit in this case. What little I understand about the steering motors is that they seem to try to maintain a constant volume, and pressure varies as required by load. With a wide front and a loader you are going to need to build some higher pressures (a full bucket trying to turn the wheels at a dead stop). Where the magic point is I don't know without trying it, but with a pressure relief valve you would just loose the power assist when you needed it the most.

If it were me, and I had the time, I would replace the gears and install the whole system at once. If I didn't have the time, I would install the pump for the PS motor temporarily and listen for a load on the motor as the sign that I was on thin ice and should back off (ie: don't try to turn without the wheels moving). You've heard the old mechanic's line, "You can pay me now or pay me later.". With that much hydraulic load you will want it done right as soon as possible.

Well heck. I didn't realize that these things had that much umph.

If you guys think it will handle the power steering as well as a F-11 loader, then I'm gonna put in the whole schmeal; gears, cover and all.

I think you guys just made my day; that would give me 'live' all the way around!

Thanks for your help,

Allan

You could pull the distrubutor and see for yourself. Who knows? Somebody may have already replaced the timing set.
