I just acquired a Cat 325BL with a JB Hendrix pin grabber. It's a C-linkage setup so has the 80mm pins, with 13.71" between ears and 19.1" ctc for pins. While I'm on the hunt for attachments, how much play can I get away with on the pin layouts? I'm assuming I have to stick with 80mm pins but not sure how much wider on the ears or +/- on the pin ctc distance? Is there a rule of thumb on this?
On my JB Hendrix couplers, they will not accommodate other pin center distances. You need a "multigrab" coupler of you want to run other pin centers.
Thanks for the info. Was hoping I could go an inch shorter to 18.25" ctc as there are some options for me then but doesn't sound like that is possible.
I've been looking on the internet about info on 'multigrab' coupler specs but really have found anything specific for my 325B with C-linkage. I did find this pretty nice brochure for a Case coupler but can't find similar for my Cat. Any recommendations on a good multi-grab coupler for a Cat 325B with C-linkage? CB-linkage also looks to be similar as I could bush the coupler to use 80mm pins instead of 90mm. Not ideal but possible.
Here's a Caterpillar rebranded "Miller Bug" But, all the "multi grab" or "multi fit" couplers run off bucket curl oil, whereas your Hendrix operates at pilot pressure. Putting a used coupler on your machine will, most likely, require a different control valve and a touch of plumbing changes. https://www.machinerytrader.com/listings/construction-attachment/for-sale/26799719/cat-1608288
Heymccall- Yes, I see now how my JB Hendrix coupler is only for one center-to-center pin without any play. I have the Gen 1 version which has no wiggle in it- can easily see that when comparing the link-pin portion between the Cat coupler you posted above and my Hendrix coupler here. I did find some older Cat sales literature that describes the tolerances in some of their older couplers- I'll add them here for other folks who may need them. I'm still amazed at how hard it is to cross-reference parts and pieces to see if they fit for these machines!
