Jaw Teeth Maintenance

When jaw teeth are worn or cracking, performance decreases and teeth need replacement. MDP can have Swift-Lock Teeth or Weld-In Teeth.

Replacing Swift-Lock Teeth (MDP 20/27/35/50)

1. Locate flat, hard ground and place the attachment on the ground.
2. Remove washers on each side of each tooth, using a grinder. Note: Washers are welded into place.
3. Use a soft metal drift and mallet to drive out the tooth pin.
4. Remove the tooth from the receptacle. Note: The retainer ring may fall out.
5. Insert the retainer ring and a new Swift-Lock tooth.
6. Insert the tooth pin and weld the washers in place. Ensure the pin groove aligns with the retainer ring.

Replacing Weld-In Teeth (MDP 90)

1. Locate flat, hard ground and place the attachment on the ground.
2. Preheat the area around the tooth receptacle to 250°-300° F.
3. Using carbon-air arc gouging, remove the weld material holding the tooth.
4. Remove the tooth. Fill and sand gouges, then clean the receptacle.
5. Fit the new tooth into place.
6. Weld the tooth into place.
7. Cover the weld with a heat blanket and allow to cool slowly.

Lubrication

Use premium grease, No. 2EP. Grease fittings are indicated by yellow “GREASE” decals. Grease each fitting with .3 oz (8 g) of grease.

Turntable Bearing Lubrication

Warning: Stand clear of MDP during rotation.

1. The turntable bearing has 1 to 4 grease fittings. Use lithium Grade 2 extreme pressure grease. For operation below 0° F, use Grade 0 grease.
2. Grease a fitting with 4 shots (.2 oz) of grease.
3. Stand clear and rotate the attachment 360°.
4. Grease the same fitting with 4 more shots (.2 oz) of grease, or until grease escapes from the bearing seals.
5. Perform steps 1 through 3 for every grease fitting.

Planetary Gearbox Lubrication (Select Models Only)

Some models use a planetary gearbox. The gearbox oil must be changed regularly based on the Planetary Gearbox Oil Change Schedule:

Gearbox Oil Change Procedure:

1. Access the gearbox.
2. Remove the oil fill plug.
3. Remove the oil drain plug. Drain oil into a container larger than 2 quarts. Note: Plugs are magnetic and collect metal filings. Discard filings.
4. Install the oil drain plug.
5. Fill the gearbox with oil as specified in the parts manual.
6. Install the oil fill plug.

Inspect / Torque Bolts

Inspect all bolts for damage. Check torque and replace damaged or over-torqued bolts. Use replacement bolts of the same size and class. Unless specified, use class 10.9 metric hex head cap screws, class 10.9 metric flat head cap screws, and class 12.9 metric socket head cap screws. Ensure new bolts are clean and dry.

Warning: Never use an inferior class fastener. Fastener failure can cause damage, injury or death.

Notice: Replace Rotation bolts after 1500 hrs / 2 years. You may need to rotate MDP to access bolts.

Build Up & Wear Plates

Worn areas of the jaws need to be built up to prolong attachment life. Wear plates protect commonly worn surfaces.

Caution: Wear safety equipment when welding. Work in a well-ventilated area.

Checking and Replacing Wear Plates

Wear bars are welded into the jaw and must be replaced when worn down to 1/4 original thickness. Use the MDP parts manual to order wear plate kits.

Installing Wear Bars

1. Preheat the area around the wear bar to 250°-300° F.
2. Remove the worn wear bar.
3. Fit the new wear bar into the receptacle. Note: Wear bars are pre-cut and must be formed to the jaw.
4. Weld the wear bar into place.
5. Cover the weld with a heat blanket and allow to cool slowly.

Jaw Teeth Build Up

1. Obtain the proper tooth build up template. Refer to the parts manual for part numbers.
2. Thoroughly clean the area to be built up. Grind off any existing hard-surface material.
3. Preheat the area to 200° F (93.3° C) to remove moisture.
4. Preheat the area to be built up to 300°-400° F (149°-204° C). Do not exceed 450° F (232° C).
5. Use the tooth template to determine build-up amount.
6. Using AWS E7018 welding rod, make hard surface beads as shown in Figure 24.
7. Relieve stress and remove slag after each pass by peening vigorously with an air operated slag peener.
8. Repeat steps 6 and 7 until the tooth profile matches the build up template.
9. Grind edges square to match the template.
10. Using AWS E7018, place underlayment passes, as shown in Figure 24.
11. Apply a bead of Amalloy 814H rod on top of each underlayment bead. Note: Do NOT apply Amalloy 814H to the base metal.
12. Relieve stress after each pass by peening vigorously with an air operated slag peener.
13. Taper the end of each hard-surface bead by grinding. Do NOT undercut the weld.
14. When grinding is complete, peen the area until shiny or the peener cannot dent the weld. About 5-10 minutes.
15. Cover the welded area with a heat blanket and allow to cool slowly.

Blade Maintenance

Caution: Wear leather work gloves at all times during blade maintenance.

1. Remove the blade as shown in Figure 25.
2. Grind all rough edges from each blade and clean the blade seat.
3. Rotate the blade. Replace blades when all usable edges are rounded to .25" radius.
4. Reinstall each blade using 500 Ft. Lbs. (680 N/M) torque on each bolt.

Danger: Stay at least 75 Ft. (23 m) when moving.

1. Cycle the jaws closed. Measure the gap between the upper and lower blade using a feeler gauge. If the gap is larger than .060", shim the blade.
2. Measure the blade gap.
3. Shim each blade so that the blade gap is approximately .020"- .030". Fit the shims between the blade and the blade seat. Note: Do not shim out a blade more than .125". Doing so may cause structural damage and will void the warranty.

Hydraulic Maintenance

Speed Valve (MDP 35/50/90)

The speed valve allows the jaws to shift into high speed when not under a load. Two valve spools control this speed change: the Main Spool Adjustment Screw and the Pilot Valve Adjustment Screw.

Testing the Speed Valve

Close the jaws and observe the movement. If the speed valve is working properly, the jaw closing speed will increase after 1-2 inches of movement.

Adjusting the Speed Valve

If the jaw movement doesn't shift to high speed when CLOSING, adjust the pilot valve adjustment screw clockwise until the jaws shift speed.

Thrust Washer Inspection - MDP 20/27/35/50

1. Locate flat, hard ground and place the attachment on the ground. Ensure the upper jaw is secured and will not fall during removal. Danger: NEVER remove any pins unless MDP is on the ground and blocked. Serious injury or death could result.
2. Remove the front cylinder pin.
3. Remove the main pivot group.
4. Remove the Upper Jaw from the MDP Body.
5. Remove the thrust washer.
6. Measure the thickness of the thrust washer.
7. Replace the thrust washer if the thickness is less than 0.355 inches.

Reassembly and Shimming

1. Position the Lower Jaw into place.
2. Install the main shaft.
3. Install both main bearings.
4. Remove the pivot fixture tool from the start-up kit.
5. Thread the middle bolt into the shaft and tighten until snug and the shaft cannot be pulled further.
6. Slowly tighten the bearing bolts, alternating every 1 revolution, until snug and the bearing cannot move further.
7. Using a micrometer, measure how far the main shaft protrudes past the main bearing (Measurement A).
8. Measure the wear on the right hand End Cap (Measurement B).
9. Subtract Measurement B from Measurement A to get the shim thickness.

Shimming

1. Put together a stack of shims equal to the calculated shim thickness, then remove one .005 inch shim.
2. Install shims on the right hand side of the MDP Main Pivot Group.
3. Install the right hand End Cap.

Shim Right Hand Side

1. Using a crane, slowly lower and raise the Upper Jaw. If shimmed properly, the Upper Jaw will move with a slight bit of "drag". If the Upper Jaw does not move, or has too much drag, replace the .005 inch shim removed in step 1.
2. Measure and shim the left hand end cap using Figure 34.
3. Install the left hand End Cap and torque the Main Pivot Group bolts.

Check End Play

1. Grease each fitting on the Main Pivot Group.
2. Set a dial indicator against the Upper Jaw and zero it.
3. Using a pry-bar, pry the left hand side of the Upper Jaw towards the thrust washer.
4. Pry against the right hand side of the Upper Jaw. The dial indicator should not move more than .005 inches.

Thrust Washer Inspection - MDP 90

1. Locate flat, hard ground and place the attachment on the ground. Ensure the Upper Jaw is secured and will not fall during removal. Danger: NEVER remove any pins unless MDP is on the ground and blocked. Serious injury or death could result.
2. Remove the front cylinder pin.
3. Remove the main pivot group.
4. Remove the Upper Jaw from the MDP body.
5. Remove the Thrust Washers from the Upper Jaw.
6. Using a caliper, measure the thickness of both Thrust washers. Add the two measurements.
7. If the sum is .97 inches or less, replace the Thrust Washers.
