Filling Spindle with Hydraulic Oil? Motor Seal Leaks.
Determine and correct cause of Motor Shaft Seal Leaking, Re-Seal Motor,
Clean Repack or rebuild Spindle as required. Note: Be sure to determine what
caused Seal to Blow out and repair that problem before considering the repair
to be done. If you just put in New Motor Seal you have not cured the cause of
the Problem. See Motor Seal Leaking for possible cause of Seal problems.
Motor Loose or Bolts Missing?
Tighten Motor to Spindle retaining bolts, If they will not tighten? check and repair
threads. Notice this problem will let Spindle Oil Leak but will not let Hydraulic Oil
from Motor Leak.
Gasket Torn or Damaged?
Remove Motor, Check surface of Spindle Housing and surface of Motor, Clean
Surfaces of both, Check for Burrs or deep Scratches. Burrs can be removed
by carefully filing surface, If you file surface caution must be taken to keep filings
out of Spindle. If Scratches they can be filled with a sealer. Make Sure Sealer
is Oil compatible?
Pressure in Spindle Housing? Excess Backpressure.
Make sure Relief Plug installed or Relief Plug is not clogged, Check Spindle Oil
level so it is not overfull, Notice this will be Spindle Oil leaking out not Hydraulic
Oil.
Seal Damaged? Could be damaged by foreign material.
It will be required to replace Seal and refill Spindle with Lubricant. Before
replacing Seal always check to make sure Shaft Bearings have not lost
Pre-load (Shaft will be loose in Housing) as this will make Seal Leak and will
damage Seal. If Shaft is Loose see next cause / Solution. Always Check
condition of Shaft surface at Seal Area that it is not damaged, Always coat ID
of Seal with light coat of grease before installing.
Bearings Loose?
If Bearings are Loose the Bearing Pre-Load is lost and Bearings are most likely
damaged, Remove Motor, Dis-assemble Spindle, clean and Inspect, Rebuild
and Fill with Lubricant. (See Spindle Repair / Product Service manual).
