4 ESCO MOUNTING AND OPERATIONAL INSTRUCTIONS INSTRUCTIONS: 1. Boom & rotate yokes require tension collars beneath nut. Insert welded flush to inside of ear. 2. Insert the snubber ass y between the ears of the boom or stick. Line up the anchor on the housing so it engages the retaining bracket. In some cases, shims or spacers must be added on each side of the snubber. Shim it so it can still be moved by hand. 3. Insert the pin. 4. If required, insert weld shim plate to top of rotate yoke. Allow 1/1 maximum clearance, housing to plate, providing full contact of housing. For cast yoke with inside taper, grind housing to match taper. *If required, weld shim plate to taper for tight fit to housing.. To set the tension, turn the adjusting bolts ½ turn, equally, on each adjusting bolt until the desired tension is achieved. CAUTION: Over tensioning of the snubber reduces friction sleeve life.. To replace the friction sleeve, first loosen the adjusting bolts so the pressure plate, bearing, spring washer, and the housing can be remove, then pry off using a bar on each side. Heating of sleeve may be required.. Apply a thin even coat of loctite 20 (or equivalent) to core and inner friction sleeve surface before installation of sleeve.. IMPORTANT: All service points on the snubber should be greased every 10 hours. (friction sleeve: Grease B3T-30G only). Greases with % - % MOLY are recommended: Military Spec. MIL G234C -Lubriplate 1 0 F./-1 0 C. -Lubriplate F./-. 0 C. -Lubriplate 3000w F./ C. -or EQUIVALENT WELD TENSION COLLAR FLUSH TO INSIDE OF EAR.

5 MOUNTING AND OPERATIONAL INSTRUCTIONS INSTRUCTIONS: 1. Measure Young grapple distance between ears. For less than -1/2, snubber link requires milling, maximum ¼ each side. Boom & Rotate yokes with tension collars beneath pin nut require tension collars to be welded flush to inside of ear. 2. Insert the snubber ass y between the ears of the boom or stick. Line up the anchor on the housing so it engages the retaining bracket. In some cases, shims or spacers must be added on each side of the snubber link. Shim it so it can still be moved by hand. 3. Insert the pin. 4. If required, insert weld shim plate to top of rotate yoke. Allow 1/1 maximum clearance, housing to plate, provide full contact of housing.. To set the tension, turn the adjusting bolts ½ turn, equally, on each adjusting bolt until the desired tension is achieved. CAUTION: Over tensioning of the snubber reduces friction sleeve life.. To replace the friction sleeve, first loosen the adjusting bolts so the pressure plate bearing, spring washer, and the housing can be remove, then pry off using a bar on each side. Heating of sleeve may be required.. Apply a thin even coat of loctite 20 (or equivalent) to core and inner friction sleeve surface before installation of sleeve.. IMPORTANT: All service points on the snubber should be greased every 10 hours. (friction sleeve: Grease B3T-30G only). Greases with % - % MOLY are recommended: Military Spec.
