1. TORQUE ADJUSTMENT & INITIAL STARTUP

a. These torque limiters were preset at the factory, no further adjustment is required at this time. If it is desired to adjust the torque at a later date, proceed as follows.

b. Internally Adjustable To adjust torque at the job site: Refer to detailed setting instructions of Safety Element Torque Limiters (page 10).

b. Externally Adjustable Procedure for setting the externally adjustable element: How to find zero Spring Compression

1. Release Socket Head Set Screw (2-15).

2. Turn housing nut counter-clockwise using 2-1/2” socket until spring force is removed and the housing nut is free to turn by hand. Now turn the housing by hand clockwise and determine the point at which resistance is first felt as the springs become engaged. This is the “zero point”. The number of setting marks required from the Setting Chart must be counted from this “zero point”.

3. Using 2-1/2” socket turn housing nut until the required number of setting marks from “zero” are obtained.

4. Turn Socket Head Set Screw until tight (2-15).

5. Repeat steps 1 through 6 for each safety element. How to adjust element to specified setting.

CAUTION: If you exceed the factory setting possible catastrophic failures could occur.

— CAUTION — This machine is equipped with an externally adjustable break away torque limiter. The limiter was preset to match your engine H.P. DO NOT exceed this setting. This information has been recorded and limiter marked at the factory.

2. RESETTING

On overload, the safety element ball is displaced and the Module Carrier Plate disengages from the Detent Pocket Plate, allowing the Module Carrier Hub (1-1) to rotate freely. PTO clutch should be disengaged immediately after the Torque Limiter has disengaged. Refer to Morbark operator safety manual. Then align the two reset arrows on the Detent Pocket Plate and the Module Carrier Plate by rotating the Torque Limiter by hand. After aligning the match marks strike the safety element plungers with a soft mallet and the plunger will move back into the safety element 5/16 inch signifying that the unit is engaged.

3. GENERAL MAINTENANCE

— CAUTION — The torque limiter must be greased once a month or after it has disengaged. If the torque limiter has not disengaged in 1 month, a manual reduction to “0” torque setting on all safety elements, Ref: Fig 1B-5 is required and then trip torque limiter. If this procedure is not followed, you will void any warranty on the torque limiter. Brunel’s standard warranty terms apply.

a. Disengaged safety elements, Ref: Fig 1B-5 should be greased once a month with Mobil XTC. Pump 5-7 pumps from a grease gun into grease fitting (2-18).

b. The bearings must have Mobil SHC 220 grease applied once a month through grease fitting, Ref: Fig 1B-8 until grease comes out of the grease vent. Ref: Fig 1B-9. The driving half of the torque limiter, Ref: Fig 1B-2 and driven half of the torque limiter, Ref: Fig 1B-1 of the torque limiter should be spun independently of each other for 10 revolutions.

c. Safety elements should be stripped, inspected and reassembled at least once every three years, more frequently where frequent tripping occurs. Bearings should be inspected every three years.

Figure “Ref:” may vary depending on the torque limiter style that is installed on your Morbark Grinder.

4. TROUBLE SHOOTING

a. Continual releasing.

1) Detent Pocket (2-11) worn. Remove Safety Element (1-5) to remove detent, first remove 3/8-16 SHCS and extract detent pocket using a slide hammer with 12mm x 1.75 pitch heat treated threaded rod, & Rotate Detent 90º & reinstall. If badly worn replace with new detent pocket (2-11).

2) If additional torque capacity is required. Consult Morbark Service Department.

b. Unable to screw Housing Nut (2-7) in any further.

1) Loosen Set Screw (2-15) and make sure that the threads on the Housing Nut and Housing are not damaged, if so clean & file burrs until usable or replace defective parts.

2) You have reached maximum torque capacity.

c. Unable to reset. Reset arrows not aligned. Check reference marks on Module Carrier Hub (1-1) and Detent Pocket Plate (1-2). Make sure reset arrows and line is in correct position for correct module alignment.

is seated. Screw on nut (1-3). Using spanner wrench and hammer, tighten nut and spin clutch until all rollers of bearing cone are turning. Wait at least two hours for bearings to cool.

9. Once unit has cooled it is time to set preload of bearings. Rollers probably will not turn now that the part has cooled. Check drag with a scale. Torque should be around 10 lb-ft. Using a punch and hammer, strike bearing race in four equal places and tighten nut. Repeat until all rollers start to turn. Check drag again. Repeat process until you have 4 - 6 lb-ft. of preload. Example: Started at 10 lb-ft. Should finish at 14-16 lb-ft. Remove nut (1-3). Using a grease gun with SHC 220 grease, grease bearing between rollers (1-4). Install new seal (1-6). Seal should be around 5/16” below face of detent pocket plate (1-2). Grease rubber seal surface. Remove any burrs or flaws on O.D. of lock nut (1-3). Grease O.D. of nut. Install nut. Tighten using spanner wrench. Spin clutch working grease into bearings and forming a seal of grease on nut. Drill and tap 5/16 – 18 x 3/4” deep for new lock nut set screw (1-8). Install new locking set screw with loctite 262. Turn clutch over.

10. Replace the four 5/16” – 18 set screws (1-11) removed at disassembly.

11. Install rebuilt or new modules (1-5) shimming each one with .006 - .008 preload per Preload instruction on Page 6 . Assembly is now complete.

JSE3-0014/JSE2-0014 Setting Instructions 1. Ensure Set Screw (2-15) is not locking the Adjusting Nut (2-7).

2. Hold safety element in soft jaws in a bench vice, as shown in drawing below.

3. Tighten Adjusting Nut (2-7) by turning clockwise with adjusting tool, then loosen by turning counterclockwise until all spring load is removed.

4. With with adjusting tool, slowly tighten the Adjusting Nut (2-7) until it just touches the disc springs - you will note a large increase in resistance when the nut comes up againt the disc springs. At this point the Adjusting Nut is bearing on the Disc Springs with no pre-load. 5. Arrange depth micrometer as shown in drawing (Figure 1). Measure the distance “X” from the safety element Housing (2-16) base, to the face of the Adjusting Nut (2-7). This is equivalent to the ZERO SETTING on the Load / Depth setting graph. Make a scribe mark on the adjusting nut face to note the position of this measurement and make all future measurements to this same position.

6. Refer to Morbark Service Department for depth setting for the required load, and add this to dimension “X”.

7. Using the dial indicator or micrometer depth gauge, measure depth and slowly tighten Nut until the required depth is reached. This safety element is now set to the required load setting.

8. Tighten Set Screw (2-15) to lock Nut (2-7).

Preload InstructionJSE3-0014/JSE2-0014 Safety Element Module (Blind Hole detent) 1. Grease the Detent Pocket (2-11) and press into position, install the Cap Screw (2-10) treated with Loctite or similar.

2. Place the Detent Ball (2-9) on top of the Detent Pocket (2-11) then insert the Bushing (2-8) into the hole in the Module Carrier Hub (1-1) over the Detent Ball (2-9) until the flange of the Bushing (2-8) bottoms.

3. Insert the assembled Safety Elements (1-5) (ensuring that the modules are in the engaged position) through the Bushing (2-8) until the Plunger (2-1) comes in contact with the Detent Ball (2-9).

4. With either a suitable height gauge or feeler gauge, measure the resultant gap between the inner face of the Housing (2-16) and the Module Carrier Hub (1-1), deduct .006 - .008” for pre-load and select a suitable sized laminated Shim Pack (2-13) to accommodate the gap. Then place the Shim Pack (2-13) onto the Module Carrier Hub (1-1), grease and insert the Bushing (2-8) into the Carrier Hub (1-1) and securely fix with the qty 4 socket head cap screws (2-6).

5. Tighten bolts to 1/2 torque in a 12, 6, 3 and 9 style and proceed with same manner for full torque.

Installation and Maintenance InstructionsTorque Limiters Using JSE3-0015 & JSE2-0025 Externally Adjustable Safety Elements

1. TORQUE ADJUSTMENT & INITIAL STARTUP

a. These safety elements were preset at the factory, no further adjustment is required at this time.

b. If it is desired to adjust the release torque at a later date, refer to #4 “Torque Adjustment”.

c. To install preset Safety Elements

2. RESETTING

On overload, the safety element ball is displaced and the Module Carrier Plate disengages from the Detent Pocket Plate. With the drive at rest (the power off) and the overload cleared, align the two reset arrows (or grooves) on the Detent Pocket Plate and Module Carrier Plate by turning the mill shaft by hand. After aligning the match marks strike the safety element plungers with a soft mallet and the plunger will move back into the safety element signifying that the unit is engaged.

3. GENERAL MAINTENACE

a. Disengaged Safety Element - Grease 2-3 pumps from a grease gun into Grease Fitting (2-18) every 3 months. Recommended grease is “Mobil XTC”.

b. Safety elements should be disassembled, inspected and reassembled at least once every 3 years, more frequently where frequent tripping occurs.

c. Bearings should be re-greased with SHC220 Mobil Synthetic Grease once a month.

4. TORQUE ADJUSTMENT

a. To adjust torque at the job site: Prior to setting Safety Elements which are new or which have been re-assembled, the desired release torque for the torque limiter must be known.

b. From this desired Release Torque, the required tangential force (Ft) must be calculated. Perform the following calculation and proceed with setting each Safety Element to the same tangential force from the graph supplied.

CALCULATION:Ft = T / ((N) x (R) where:Ft = Tangential force (pounds)T = Required release torque of drive (lb-in)N = Total quantity of Safety Elements on Torque Limiter.R = Mounting radius of Safety Elements on Torque Limiter (in.)

c. In order to determine “zero” and set each safety element:

1) Release Socket Head Set Screw (2-15).

2) Turn housing nut (2-7) counter-clockwise using 2-1/2” socket until spring force is removed and the housing nut is free to turn by hand. Now turn the housing by hand clockwise and determine the point at which resistance is first felt as the springs become engaged. This is the “zero point”.

3) Using 2-1/2” socket turn housing nut until the required number of setting marks from “zero” are obtained.

4) Turn Socket Head Set Screw (2-15) until tight.

5) Repeat steps 1 through 4 for each safety element.

EXAMPLE :

A Torque Limiter has four JSE3-0015 Safety Elements mounted on a 7.3” radius. We want the drive to release at 93,698 lb-in torque.

1. Determine tangential force, Ft

Ft = 122,000 lb-in / ((2 elements) x (7.3” radius)) = 8,500 pounds.

2. Read from graph for JSE3-0015, the required number setting from zero compression and set each safety element accordingly. For this example each safety element would be set to 8 (8/10 revolution from zero).

5. METHOD OF PRELOADING EACH SAFETY ELEMENT (BLIND HOLE DETENT)

a. Bolt the Detent Pocket (2-11) into the Detent Pocket Plate (1-2) using 3/8”-16 x 1.25” SHCS (2-10).

b. Grease the bushing (2-8) complete with “O” ring (2-12) and install over the greased plunger (2-1). Install the greased ball (2-9) in the hole in the Module Carrier Hub (1-1)

c. Insert the Safety Element assembly (1-5) firmly into the Module Carrier Hub (1-1).

d. Using feeler guages, measure the gap between the base of the Safety Element (1-5) and the Module Carrier Hub (1-1)

e. Accumulate pealable shims to a thickness of 0.003- 0.008” less than the gap measured in d. above.

f. Remove Safety Element (1-13) from Module Carrier Hub (1-1) and remount over shims.

g. Insert Qty. 4 7/16”-20 x 2.25” SHCS or 12pt bolt (2-6) and torque tighten to 72 lb.-ft.

6. TROUBLE SHOOTING

a. Continual releasing, further adjustment making no difference.

1) Detent Pocket (2-11) worn. Remove Safety Element and remove Detent Pocket. Rotate Detent 90° and reinstall. If badly worn replace with new detent pocket.

2) Additional torque capacity is required.

b. Unable to screw Housing Nut (2-7) in any further.

1) Loosen Socket Head Set Screw (2-15) and make sure that the threads on the Housing Nut and Housing are not damaged. If so clean & file burrs until usable or replace defective parts.

2) You have reached maximum torque capacity.

c. Unable to reset.

Reset arrows not aligned. Check reference marks on Module Carrier and Detent Pocket Plate.

7. SAFETY ELEMENT - METHOD OF ASSEMBLY

a. Clean all components and coat all surfaces with a suitable anti-seize compound.

b. Grease inside surfaces of the Housing and install Outer Thrust Race (2-2) and “O” Ring (2-10).

c. Grease Plunger (2-1) and install thru Housing and Outer Thrust Race.

d. Install 15 mm Balls (2-3), apply grease over balls

e. Grease and Install Inner Thrust Race (2-4).

f. Grease and Install 12 springs (2-5), oriented as shown in cross section.

g. Grease inner walls of Housing Nut (2-7) and install “O” ring (2-17).

h. Screw in the Housing Nut (2-7) into the Housing until there is contact with the springs (2-5).

i. Insert the Locking Pellet (2-14) and Socket Head Set Screw (2-15) into the side of the Housing to facilitate locking the Housing Nut. (Refer to #2 Torque Adjustment)

j. Grease and insert the ‘’O” Ring (2-12) into the Bushing (2-8). insert the Detent Ball (2-9) after throughly greasing the Bushing ID. Grease the Plunger (2-1) and install the Bushing.
