Pump Check Valves - Toro Reelmaster 216 Service Manual

Pump Shaft & Trunnion Seals (Fig. 32)
Lip type seals are used throughout the pump. These
seals can be replaced without disassembly of the pump;
however, replacement of either the input or output seal
requires removal of the pump from the machine.
1. Pry the seal carefully out of the housing bore, using
care not to distort the housing or damage the bore or
shaft. Once removed, the seal is not reusable.
2. Before installing the new seal, polish the shaft exten­
sion, wrap it in thin plastic and lubricate with hydraulic
oil to insure that the seal is not damaged during assemb­
ly. Slide the seal over the shaft and press it into the
housing bore.
3. To service the trunnion shaft seals it is necessary that
the retaining rings (Item 13) and washers (Item 11) be
removed before removing the seals. The washer should
be replaced if it is noticeably bent or distorted.

bore.
