Apply anti-seize compound to spindle shaft. Install spring seat and spring (not supplied) if required. See Figure 4.
Set the top-load assembly using provided spring setting chart. Lock the jam nuts using O.D. spanner wrench (YTL3-0009). See Figure 2.

Set the preliminary static torque using provided torque setting chart. Loosen set screws with hex key wrench, turn end cap with face spanner wrench (YTL2-0002). Tighten set screws to 8-10 lb-in. Over tightening is not necessary and will strip the screws or possibly damage the housing body. See Figure 3.

Setting Top Load Spring Force
1. Determine initial spring setting from spring force chart below.
2. Compress the spring with the locking ring just enough to allow the adjustment ring into its correct setting.
3. Move the adjustment ring to the desired setting. Bring the locking ring down and jam the rings together with a spanner wrench.
4. For optimum results check download force with a force scale.
5. Set headset on the scale and manually compress the spring downward 5mm. Take the force reading at this position. The lines on the spring cover are .100” (2.5mm) apart, so two lines equal the recommended .200” (5mm) compression.

NOTE: The charts above provide actual spring loads without any added load due to the weight of the headset. These spring loads are valid for any headset. Not all headsets have the full range of settings; some headsets do not have a ‘3.0’ setting, other headsets do not have ‘1.0’ or ‘1.5’ settings. The spring loads are calculated at the given deection as listed in the chart.

Setting Application Torque
1. Determine initial clutch setting from torque chart below.
Recommended Maintenance
Schedule
Lubricate the upper assembly every 500 hours of run time.
2. Loosen the torque adjustment screws. Rotate the adjustment ring using the face spanner wrench to the desired setting and then retighten the torque adjustment screws. Do not use the set screw in the slot on the backside of the housing for torque adjustment. Tighten set screws to 8-10 lb-in. Over tightening is not necessary and will strip the screws or possibly damage the housing body.
3. For optimum results, check setting with a torque wrench and FIX-0007 or FIX-0010.
