- Track-Type Tractor:
- D11N (S/N: 4HK1-UP; 74Z1-UP)
- D11R (S/N: 8ZR1-UP)
Reference: Service Magazine, SEPD0261, 3 July 1995, "Large Special Taps with Spiralock Threads Provide Improved Bolt Retention"
- Tighten bolts (3) to a torque of 2200 ± 200 N·m (1621 ± 147 lb ft). Tighten the abutment side of the cap first to the proper torque. This is marked on the cap "TIGHTEN FIRST".
Note: Large special taps with Spiralock threads are available. Spiralock threads are used on the minor bogies on the tractor's undercarriage. Spiralock threads provide improved bolt retention.
Note: Use of a standard tap in those holes will eliminate the Spiralock feature.
