The spring retainer has been modified to allow for the
additional thickness of the spring seat and a groove
machined into the hex end cap serves as a visual indica-
tion that the valve contains the new spring seat. The
spring seat improvement may be added to earlier brake
valves by installing kit, Part Number 62805. Items 3, 7,
13, 14 and 22 are included in the kit. We recommend that
this kit be installed whenever the brake valve is removed
for inspection or service.
It is always a good practice to check the initial opening or
“cracking” pressure of the brake valve whenever the hoist
is serviced or inspected. Refer to Braden Service Bulletin
527 for complete brake valve test and adjustment proce-
dures.

Allen wrench

1 1/2 in. valve
3. Remove the spool spring retainer and spool spring.
Remove the spool plug and carefully remove the spool
assembly. Remove the damper piston from the spool.
The piston will come out of the spool slowly, because
of a partial vacuum formed between the two. Use
extreme care to avoid damaging the polished surfaces
of either piece.
4. Remove the check valve spring retainer, spring and
check valve poppet.
1 1/2 in. valve
