Pulling wood out of the brush?

[sawinredneck]

Is it a coupler or is it the end of the crankshaft?

And there you go!

 

[sotc]

i cant imagine theres enough wear in that spline to make any amount of difference driving the pump

Andy,
I see two pins that make me think it is and adapter pressed into the crank end.
As to how to get it out and where to find the new one, in the larger size?
I would think the manufacturer knows more than they are letting on.

 

[sawinredneck]

Yeah, I saw them as well, Thomas has yet to return my call. I tried driving them in, hoping it would force it out, they didn't move. I have yet to figure out how to use an internal puller to grab the radius.
I am leaning to just putting it bak together and running it until something just breaks right now.

 

[sotc]

think pilot bearing, pump some grease in there, use the old shaft...... or leave it be

I would try a pilot bearing puller, the slide hammer type. Snap on makes a good one. Might try a little heat, with a good heat gun not the torch.

I've welded a bolt to the inside diameter of what I was pulling. Now I have something to grab on, and the weld makes the piece smaller.

No heat at all, it's too close to the seal, and those Kohler seals can be a real PITA if they go!!!

I don't want to weld on it because I may not be able to find another one reasonably or quickly. I would love to get it out to at least take some measurments so I could start machining a new one. Which will take weeks by hand!

 

[Reddog]

It may be threaded in and the pins keep it from un threading.
Might want to understand it before wrecking the crank.

 

[sawinredneck]

Thomas called me back, they didn't have one but had the Kohler part numbers on hand. I finally found a place in town that would order one in, the number has changed and nobody is sure it's the exact thing
It will be in tommorow, $65. When it gets in, IF it fits the pump and looks right, then I will start tearing the old one out.

 

[SkwerI]

Cool deal! Plus, inspecting the new one should tell you how it's attached. Of course you already knew this.

Man sorry for the big PIA, I hate sellin used stuff.

Darin is the engineer Dude at Thomas hes the man to talk too,
Sorry Mike (me Mechanic) didn't get back to you, told him to call you back to day if he got the chance

Sounds like you might have found a solution get ready for that thing to jump out of its skins the pump has the same # but must be + - 12gpms compared to the tired factory 8gpm

damm hope you get her up and running quick again

Going to measure and see if that will fit in my machine. I'd have enough flow to stall the engine

I ain't meaning to bitch Dave, you have done me right, told me what I was buying and hooked me up with parts. I bought a USED piece of equipment, and that is what I got!
I don't know if Mike would have been able to help even if he did call me back. I doubt he ever had to change that coupler. And the more people that looked at it, and the more I looked at it, it was worn badly. It would be foolhary of me to to replace the pump but not the coupler. Also with this being a bigger input shat with more splines, it's the way to go!!
The numbers on the pumps are identical, this pump has been changed already as far as I can tell.
The website lists it at 8.5GPM, these pumps are rated at 10.3GPM. Shouldn't be a problem at all once I get the coupler worked out!

Should work Carl, you will have to plumb in another supply line for the second section, not a biggie.
And yeah, if you load both sections, it will stallthe motor for sure!

 

[lumberjack]

If it will fit or not is the biggest question.

One section at full flow and 3kpsi would require around 30hp to keep from stalling the motor.

 

[sawinredneck]

I know the input shaft is the same as the one I took out of mine. I can measure my pumps easily if you can get specs for the standard.


3.25" OD on the alignment ring, 4.190" is the bolt center.

 

[lumberjack]

The physical size of the pump, everything else checks out.

 

[sawinredneck]

I see. I seem to recall having four inches of usable room on the backside of the pump, front of the machine. There is a large bundle of hoses that might have to move to the right side of the pump. You may also have to lengthen the front hose a bit. Not sure how much slack is there when you cut the ties?

Dude ~~ nice Exec look, the firewood tycoon! hey call my cell when you get a chance

Part is finally here!!! This should be a hoot I'll get pics of everything in a bit.
This is not for the faint of heart!!! The destructions say to pull the crank out, make a holder and put it in a vise. Weld a 7/16-20 nut and bolt to it to press it out. Easy enough.
THEN you put in the new one and using a #30 CARBIDE drill bit, you drill between the crank and adapter 90deg from where it was originaly
I'm not buying a $50 drill bit, so........................................

 

[sawinredneck]

Well that was a real hoot!!!! I hope I never see another one of those couplers again!!!

Two 7/16 nuts, four welding rod, two gallons of gas, one fire extinguisher and a LOT of frazzled nerves latter, it's finally in!!

Pics to come when moma gets home with her 'puter!

Andy, I just noticed something...you're never supposed to button the bottom button on a suitcoat FWIW

 

[okietreedude]

Boston, you expect a redneck to know that????

 

[CurSedVoyce]

<-- hillbilly knows it why not a redneck .. LOL
