Q: Mike
I have a Troy Built 6.75 HP (model 01904). Would this pump be a good replacement for it? Do you have any other recommendations? We use it just around the house and barn so it's not used a lot but at times can run for several hours on a job.
Thanks

by Charles Randall from Michigan on June 11, 2015

A: Please confirm you have a 3/4" hollow engine shaft. This would be a great pump, however I do recommend the fully plumbed version so it comes with the inlet and outlet fittings, unloader, thermal relief valve, and siphon hose. This way you just need to take off the old pump, slap this one on and you are ready to go!

Fully Plumbed Pump
by Brian, Product Expert
Q: 3/4 in shaft by what length?.Is the mounting bolt pattern regular 2.5 in square,these are the mosssst important things you should advertise!!!,NOT the rest of the garbage
by Nathan Raghu from Louisiana on June 02, 2015

A: There are multiple locations this pump can bolt on. What brand engine do you have? This will bolt up to any 3/4" horizontal engine shaft, that was produced in the last 10 years.
by Brian, Product Expert
Q: can I put a 3000 psi pump on 4hp motor
by Paul Lemoine from Louisiana on March 02, 2015

A: No, you will need to attach this to a 6.5 HP engine or larger. We do not have a triplex plunger pump compatible with a 4 HP engine.

Exact Fit, Works Great
My pressure washer is a Dewalt with Honda Motor and CAT pump I bought new in 2005. I used it commercially.

I went to look to replace the pressure washer when the pump went out, but it was gonna cost me 1000. To get one like I had. So I ran across Pressure Washers Direct and saw I could replace my pump for 260. Then I got a new hose, sanded prime painted by frame, serviced my motor, put all together and it's better than new.

I love the new CAT pump. I hope I can get 10 years out of... more

CAT pumps do last a long time if serviced regularly- and many can be rebuilt!

Josh,
We have a request in to the folks at CAT Pumps for the pump exactly the way it ships- so far we haven't gotten one, but we'll keep asking! The note about the fittings is in the Features in bold, capital letters- it's only fine print if you're looking on a small screen; it's the best we can do until we get a fresh picture from CAT.

Had an old Ridgid power washer with a bad Cat pump on it, PED hooked me up with the correct replacement Cat pump for it.

It was easy to install, a lot easier than removing the old Cat pump and I am back in business. I would recommend PED for any do it yourself-er they were great to do business with.
Thanks PED

Awesome Pump
I'm glad I found PED online. They have great products and really good prices.

I was looking to replace the seals on my 10 year old Cat pump but the parts alone was expensive. so I just decided to get a new one. My pump came with oil.

BTW, though I wanted replace the seals on my old pump it was still in good working conditions. Cat pumps are the best pumps in the industry.

Does not come with thermal relief valve. You have to adjust the pressure. Not ready to go!

Jaime,
A bare pump is just that- just the pump.

If you'd like a replacement pump with connectors and tubing, then you may want to look at the Slap Happy Replacement Pumps that come with all the bells and whistles.

Best Compact Pressure Washer Money Can Buy
I needed a pressure washer and I looked everywhere to find a special one to to fill my needs.

This is the ultimate machine for cleaning decks & concrete. The thing about it, it's quiet and has an adjustable nozzle on the tip of the wand so you don't have to stop it to install a tip every time.

You can choose 800 PSI for light stuff or switch to 25 degree or 45 degree for more pressure; & the Cat pumps are very durable. And, it's pretty good on fuel consumption.

Good Pump
Ordered the Cat Pump as a replacement and upgrade to the original pump on a TroyBilt washer. Pump arrived in short order. Then I find I need to order a thermal relief valve from a different vendor. It arrived in short order.

Then I find I need a pressure gauge to calibrate the pressure relief valve from yet another vendor. It sure would have been quicker and easier if everything had been included with the pump, or, at least, available to order with the pump. After all is said and done, the... more

Doug,
Bare pumps are sold, well- bare; assuming that elements from the old pump will be re-used. The Slap Happy pump kits that we sell include the siphon tube, hose connectors and pressure valve.

You would still need to purchase the pressure gauge separately; but we sell those, too.

Cat Triplex Pump, 4ppx30gsi
I ordered this pump because my old original pump did not build pressure any more and after some research the new pump purchase was about as cost effective as rebuilding the pump with out taking the time to rebuild it. The only problem I had with installing the new pump was that the adaptor plate did not have threads cut into the holes. I had to tap threads myself into this plate which was really no problem.

Works great, and a lot cheaper than buying a whole new unit.
Pros: Easy To Use, Price, I'd Buy It Again
Cons: Incomplete Machining On Adaptor Plate

Great Pump!
This is my second cat pump of similar pressure/GPM. The first one replaced a cat that was 15 years old and used 1-2 times weekly.

If this one lasts half that long, I'll be tickled. It seems excellent! Quick shipping!
