    Excellent replacement part

    Posted by Chris R. on 13th Aug 2017

    I have a 5DX model CAT pump. It's an older model and the 3/8 pass-through bolt on the unloader broke. I looked high and low for a replacement bolt only to learn they are not available for my pump unloader anymore. After searching for a new unloader, which is available at a couple other online sites for over $250, I ordered this one. I was pleased to find out this unloader is made of high-quality parts. Although no directions were included, it was still easy to install and works very well! I am very happy with this unloader and highly recommend it to anyone looking to replace their unloader on the appropriate models.

    the perfect rememdy

    Posted by tommy on 13th Apr 2017

    it always bugs me to throw away an expensive machine because a part of it is broken. i bolted this thing on and went right back to running like brand new.this is a way better design than the original.

    It works

    Posted by Wayne on 12th Aug 2015

    mine came with no instructions, it plumbed up
    different from the one on my pressure washer.
    Put it on the way the old one was fitted, but
    would not work, tried the way I seen them online and it worked, instruction would have
    saved me a lot of time.....works OK

    Needed a reducer to make it work.

    Posted by Don on 21st May 2015

    Got the KPL308 for my 5DX. All went together well except the nipple on the bypass hose on the inlet side in the kit is too small for the tee and I had to make a trip to the store for a reducer. Other than that it works as advertised.
