If you did, how is it done?

I already have the rebuilt CAT 435 pump on it's way from Butler. Seems like Butler is an exclusive source for this pump. I will have to send this one back. I want to save the clutch and set it up on an old CAT 430 pump I have in stock for emergencies.

Wait of 8 days for a pump from the east coast.

We just do the Butler exchange.

Too many times I have seem guys try and save money doing it themselves and in the end could have really had like brand new from them for a few more dollars..

So I just call for a rebuilt unit and send the old back.

And that is only after about 3800 to 4500 (sometimes more) hours. Really a bargain.

Funny how these TM makers make sure there are no part numbers on things so you can't just go to an autoparts store and pick up a PITT clutch for half the price.

Updated info is that my rebuilt pump from Butler will take only 7 days to get here.

The pulley came off really easy. I used a slightly longer shaft bolt to set the clutch on my replacement pump shaft. Everything else transferred over to the Cat 430 pump just fine and it was up and running quickly.

This modification does require deleting the chemical injection pump. Fine by me, I attended the Art Kelly School of Buggery.

The Butler is one simple rig to work on! I did this as a temporary fix, also preparing for future emergencies. Butler better not charge me more for the core without the clutch. There is a $200 charge for a new clutch on the rebuilt pump return program.

Not the ones I've been to. Napa, autozone, Oreilly etc. They don't want the liability if they sell you the wrong part.

Had to look at a Pitts website to figure mine out.

My last straw with butler was the water pump. They made sure to have cat make a pump with their own proprietary sticker so you have to buy a pump from them at 2x the cost it should be and wait 8 days to get it. I swapped out another cat pump with identical RPM and water GPM for half the price and got my butler making money again. After that I said no more of that crap.

aren't there threads on that clutch that you can send
a bolt down the center to push it off the shaft......

i see that pulley distorting already from being pulled wrong
Enlighten me Bawb, how is it being incorrectly pulled?

You can see in the pic that there are no threads on the clutch for removal, like you would see on a harmonic balancer.

It popped off really easy with the jaw puller using very little force and without any distortion.

What pump did you use Mike?

The 2nd pic is of a Cat 430 pump I setup for the Butler with chemical injection deleted.

OK NEWMAN......lol ....the center hole of the clutch has threads. ..3/4 maybe 7/8...if you run a correct size bolt down thru the threads it will push the clutch right off the shaft
Of course you have to remove the center bolt that' holding the clutch on first.....

Just razzing you Bawb, you have forgotten more than I will ever learn! The only threads are on the pump shaft itself. Nuttin on the clutch.
