New Seal Protector Added to Blade Bar Assembly:

A few machines have experienced operational problems such as failure of the blade bar to rotate when the mower is engaged or a slight loss of power at the blades. Sometimes it is assumed that the spindle has seized and the spindle is replaced without investigating further.

The problem is usually found to be that the spindle end cap cover is binding on the spindle housing, creating sufficient drag on the shaft to result in the symptoms described above. This condition is a result of material (Vines, Wire, etc.) wrapping around the cover and forcing it to contact and drag against the spindle housing, causing no damage to internal components of the spindle.

A new seal protector has been designed to aid in preventing material from wrapping around the seal cover area. While nothing can completely prevent material from getting to the seal cover, the new seal protector should greatly reduce the probability of spindle seizures due to these causes.

If a machine is operating or is going to operate in an application in which material is likely to wrap around spindle, the following parts can be ordered and installed. The old seal protector (# 02968868) which is on the spindle will be removed and discarded. The Old Part No. 02968868 will be ordered but the new Seal Protector Part No. 02970459 will be shipped with installation instructions. If only the new Seal protector is ordered the instruction sheet will not be shipped.

The new seal protector will have to be welded to the upper blade bar as shown on the next page and the old seal protector which is on the spindle will be discarded. Make sure that the Blade bar retaining bolts are properly torqued when reattaching to spindle and that components are good condition.
