SPINDLE SERVICE PROCEDURE (Cont’d)

1.Using a 3/16” cape chisel, bend out the staking indentations on each side of the bearing adjusting nut. To do this, place the chisel in the groove and parallel to the shaft. Drive the chisel downward until the indentation is free of the shaft and threads (see Figure 1).

2.Using the same chisel, straighten the tang on the lockwasher (if equipped with a lockwasher).

NOTE: The lockwasher will not be installed during assembly if the spindle uses the staked adjusting nut.

3.Remove bearing adjusting nut and lockwasher (if equipped). Discard these parts. They are not reusable. Install a new adjusting nut when assembling.

4.Screw the original blade bar bolts into the flange of the spindle shaft until they contact the bearing ring (see Figure 2).

5.In a clockwise pattern, rotate each bolt 1/4 turn (see Figure 3). Continue turning the bolts 1/4 turn at a time (maximum of 3 turns), until the special shanked bolts (P/N 02964353) will thread into the spindle.

6.Remove the original bolts and replace them with the shanked bolts. Screw the shanked bolts in until they contact the bearing ring.

7.In a clockwise pattern, rotate the bolts 1/4 turn at a time until the spindle is free from the housing.

Alamo is a prominent historical site located in San Antonio, Texas, that embodies a rich tapestry of events from the early 19th century. Originally established as a Spanish mission known as Mission San Antonio de Padua in the early 1700s, the Alamo has become a symbol of resistance and valor in the face of overwhelming odds. Its most significant moment came during the Texas Revolution in 1836 when a small group of Texian defenders made a valiant stand against the much larger Mexican army.

The architecture of the Alamo is a distinctive blend of Mission and Spanish Colonial styles, characterized by its thick limestone walls and arched doorways. The site features the famous chapel, known for its adjoining long barracks and a simple yet iconic façade that captures the spirit of the era. Despite suffering extensive damage over the years, the Alamo has been meticulously preserved and continues to serve as a key historical monument.

Technologically, the Alamo has undergone various renovations and restorations to maintain its integrity against the elements and modern advancements. Preservation efforts utilize contemporary methods such as laser scanning and 3D rendering to create accurate models for restoration. These high-tech methodologies ensure that any repairs or alterations respect the original structure while improving its resilience.

One of the remarkable characteristics of the Alamo is its role as a rallying point for Texan independence. The phrase "Remember the Alamo!" has transcended its historical context, serving as a powerful battle cry not only for Texas but also as a symbol of determination and sacrifice in various struggles for freedom worldwide. Visitors to the Alamo can engage with interactive exhibits and educational programs that delve into the complex narratives surrounding the site, enhancing their understanding of its significance.

Today, the Alamo attracts millions of visitors annually who come to explore its historical grounds, reflecting on the bravery exhibited by those who fought there. As a UNESCO World Heritage Site, the Alamo stands as a testament to the unique cultural heritage of Texas, blending history, architecture, and the enduring spirit of resilience that continues to inspire generations.
