Cat 420F hook up

JS Myers ยท 2020-12-17 15:53

Howdy folks! New to the forum here, as you all can tell! So I recently started working for an attachment manufacturer and started lurking around here a couple months ago to try and educate myself on various pieces of equipment and the like. It's been very informative, and I appreciate it. So on to my main question. We had a request to build a bucket for the latest version of the 420F, but we are having trouble finding the hook up info. Cat goes out of their way to keep us aftermarket guys guessing. Would any of you fine folk be able to supply me with the following specs? If so, I would be eternally grateful. We need stick width, pin diameter and length and pin center to center. Any info is greatly appreciated!

    Welcome to HEF, JS ! Any rental company's nearby that has one you could measure ?

    Welcome to the Forums JS. Call your local Cat Rental Store and rent a new 420F for a couple of days and make your template - done.

    Front loader bucket or rear digging bucket?

    420s have had the same coupler size across multiple series it's not going to change for the simple fact people wont update all there attachments for a new backhoe

    My 416Cit and 426Cit machines have a different pin center distance than my 420E machines. The rear buckets cannot be interchanged because we have the oem mechanical coupler. If they were pin-on, they'd interchange. All of mine have a 50mm stick pin and 45mm link pin.

    Rear digging bucket.

    This one does have the 50mm and 45mm pins, were just not sure on the stick width and center to center.
