Hydraulic adjuster identification

More

Lookin' for a little help in identifying the hydraulic adjusters pictured below. They are aftermarket , but were used on Cat. The following stampings were on the (2) adusters. No particular order

'H'
'604'
'H6541'
'H6540'

Thats near as eye can tell.

Need to locate the proper seals to recondition or the specs on same.
Anybody know who made them?
Anybody have some like them that have been rebuilt, and how so?
What about alternatives to get them in shape if unable to specifically ID?
Particular concern is the dimensions of the proper seals to repair, if I had that would be able to find them.
thanks

Here we go again:rolleyes: :rolleyes:
I'd be checking what they are supposed to fit first, remember your serial number D6 only shares the guide with the early double spring arrangement. Everything else is a different part number and probably dimension to.

If I had to guess as to who those units were made by I would say Frank Cline Tractor Service out of Arcadia, Florida who had patent and manufacturing rights. No telling if they exist any more or not. The info I have says they were located at 1420 E. Oak St in Arcadia......phone:rolleyes: WALnut 8-8351 Rt. 1, Box 49
Built units for the 9U and others.........$245/pr.....in May of 1967

As far as seals I would think any good hydraulic service/repair operation would be able to match up replacements based on dimensions.

Replied by yellercat on topic History on adjusters
O.M. - You never cease to amaze me! That's good history. Figured that these were pretty uncommon, scarce, etc. Wonder if anyone is running some right now? Going to a hydraulic shop to see what they can fix up. Seems that they each have only (2) seals on the main shaft. Does that sound like what you are thinking of ?
What kind of rise or protusion from the shaft outward would you guess that they use ? That is , what height on the seal from the 'face' of the (inner) shaft? Or put another way, what dimension between the sealing surfaces?
thanks for the info....

Works the other way round. Based on diameter of the cylinder and rod a lip type seal will be selected to do the job. Hydraulics supplier will have specs for the application and anticipated pressures. You may be looking at some machine work if either cylinder or rod are severely corroded. Your on your own as to whether they will fit your application.
