where can i find new boots for the control valves on my 503 the tire lean valve leaks really bad from time to time
Can you show a picture of them? The galion control boots on the cranes are notorious for leaking, and boots are available for them.
If the boot is physically good, the leak is probably deeper. Most boots on hyd control valves are only to keep dust, dirt and water out. The spool seals( o-ring or quad seal) keeps the oil in.
I will send you the part numbers for the boots and rubber rings under them tomorrow.I get them from Komatsu, They can not look them up but if you tell them the numbers I send you they will get them. Hard to believe but that fixes it. Sun coming thru glass is hard on them, not to mention the years, Ha!
Komatsu part numbers: Boot = 59276A Ring = 21924R1 Fits my 1976 Galion 503L with detroit 353
mine is a 1968 503L also with the detriot
Those look just like the crane control sectors, I get boots and seals from contractors crane in houston. From the looks of the other ones, I'd order a few, so you've got extra's on hand when you need them. Buy Broderson & Galion Crane Parts Supplier | Contractors Crane Co.

These boots I posted the numbers for are identical to the ones in the post from MCF Enterprises. 2.5 inches tall and held on by the same rings shown in the picture, upper and lower. Thank you, Crane Operator, for the tip on supply as yes, they do not last. They have a rubber ring under the pot metal piece with the two half-inch head bolts. I coat them up with blue silicone when assembling as it can leak there making you think it's the boot.
thankyou i will work on that and go from there
