This hitch is specifically designed to suit the 510mm Pin Centers of a Hyundai R290LC as there are extra Pin support hooks placed to suit this exact distance (see extra curved black material below/above the yellow dashed line in pics# 2 / 8).
If the extra curved material is removed, the hydraulic 'sliding bed' (yellow) pin hold mechanism should pickup attachments with Pin Centers of less than 510mm.

Has Lifting Eye Hook (see pics# 1,2, 4-7).


*** Pin Setup Dimensions (where your Dipper Arm goes in):
* Pin Diameter: 90mm.
* Pin Center to Pin Center (CtoC): 510mm.
* Between The Ears (BTE): 401mm Between the inside Ear Bosses of the hitch (which can be shaved back up to 424mm between the Ear Plates if you need more inside width for your excavator's dipper arm to fit in).
*
*** Pin Setup Dimensions (where the Hitch goes in your bucket):
* Pin Diameter: 90mm or 80mm.
* Pin Center to Pin Center (CtoC): 510mm (and possibly lower if the extra pin support hooks are removed as mentioned above).
* Between The Ears (BTE): 391mm but there are extra spacer plates welded on (see pics# 1-4 & 7-9) to fill the gap to suit the BTE of a Hyundai R290LC. These could be cut off to bring the lower hitch width down to 359mm if you need it narrower to fit into tighter buckets.
