I have a 1958 Cat D7 17A dozer and my blade cylinders have seen better days. The right side seal retainer broke a bolt then cracked the corner of the seal retainer off. Both right and left cylinder shafts are grooved from a lifetime of grit. The dozer serial number is gone. Are replacement cylinders either original or aftermarket available? I’m trying to avoid having to weld, turn & rechrome the shafts and fabricating a new seal retainer plate. Any suggestions?
It might be possible to identify the cylinders if you look at the head for a Part Number cast into the metal. Back in those days the hydraulic system had a different Serial Number to the tractor so the tractor S/N would be no help anyway.
I have the 2 aluminium retainer seal 1j344 and should have the shim and maybe more for the d7-17a hydrolic cylinde
Won't help this issue but next time you need your machine number or at least the number of your motor if its been swapped its in the casting below the magneto . Picture is of my D47U number but its the same place on my D7 . Just below the little stick on the flat area .
Thanks, I’ll check it out
