Tools required for engine tilting method of removing crankshaft:
Never use the engine tilting group unless the engine base is securely fastened to its foundation.
The procedure described is for removing the crankshaft where there is a minimum of overhead and side clearance.1. Always position 5B1181 Turnbuckles (5) so the left-handed threads are toward the top of the engine. 2. Mount FT731 left and FT735 right Support Beams (10) and FT734 Supports (11) on the respective sides of the engine. D398 and D379 Engines use FT113A and FT113 Support Beams.3. Install 8F4239 Blocks (2) and 8F4226 Yokes (9) on Support Beams (10) and thread 8F4230 Studs (8) [14.5 in. (368,3 mm) long] into 8F4226 Yokes (9). Use jam nuts on studs as shown. If the engine is installed with vibration isolation dampers, place wooden blocks on both sides of each damper. This will prevent excessive load on the damper when the engine weight is shifted in the tilting operation.4. Thread 5B1181 Turnbuckles (5) onto studs (8).5. Thread 8F4231 Studs (4) [9 in. (228,6 mm) long] into the turnbuckles.
The turnbuckles and studs must carry the load evenly and must be operated evenly or they will bind. If any one turnbuckle is excessively hard to turn, correct the binding before proceeding. Forcing may cause damage to threads.

1. FT736 Bracket. 2. 8F4239 Block. 3. 8F4226 Yokes. 4. 8F4231 Stud. 5. 5B1181 Turnbuckle. 6. 8F4228 Hinge yoke. 7. 8F4225 Bolts. 8. 8F4230 Stud. 9. 8F4226 Yoke. 10. FT731 and FT735 Support beams (left and right). 11. FT734 Support beam. 12. Bolts. 13. Steel plate.6. Thread the top of 8F4231 Studs into 8F4226 Yokes (3) and attach 8F4239 Yoke, block (2) and FT736 Bracket (1) to the cylinder head.7. Install 8F4225 Bolts (7), (six for D399 and D398 Engines and four for D379 Engines) in place of the bolts used to secure the block to the engine base.Be sure to place blocking with a steel plate (13) under the 1A8628 Bolts (12) in all support brackets (11).8. Raise the engine four inches (101,6 mm) with the turnbuckles so 8F4228 Hinge Yoke (6) and 8F4233 Hinge Block can be installed.
The engine must be kept level while it is being raised. If an excessive amount of effort is required to turn one turnbuckle, or hinge block and hinge yoke mounting holes do not line up, check the opening around the engine base with a scale. Adjust the distance at each corner of engine block to base to be equal.
9. Install 8F4228 Hinge Yokes and 8F4233 Hinge Blocks between the block and the oil pan base. Use L1178 Bolts between yoke and oil pan base and bolts removed to fasten hinge blocks to the block.10. Remove the 8F4225 Guide Bolts that were installed in Step 7.11. Begin tilting the engine by turning the turnbuckles on both sides of the engine. When the ends of the studs are even with the inside base of the turnbuckles, replace the 8F4230 Studs with FT111-A studs 20.5 in. (520,7 mm) long. Replace studs one at a time.
Extending the studs ends farther than flush with the inside base of turnbuckles might cause damage to the threads on the studs and in the turnbuckles and result in accidentally dropping the engine.
12. Continue to tilt the engine until the studs are again extended the permissible distance. Remove 8F4231 Studs and replace with FT733-5 Studs 11.5 in. (292,1 mm) long. Remove the FT111-A Studs and replace with FT733-10 Studs (18) 23.5 in. (596,9 mm) long. All of these replacements are on the side being opened. Before tilting the engine further, remove 8F4230 Studs from the "hinged" side of the engine and replace them with FT111 Studs 10 in. (254 mm) long.

Remove FT733-5 Studs and replace with FT733-7 Stud 18.5 in. (469,9 mm) long.14. Continue to tilt the engine until the studs are extended the permissible distance. Remove the FT733-7 Studs and replace with FT733-9 Studs (15) 21.5 in. (546,1 mm) long. Move to the "hinged" side of the engine and remove the FT111 Studs and replace the FT733-2 Studs (21) 8 in. (203,2 mm) long. Remove the 8F4231 Studs and replace with FT733-1 Studs (20) 6 in. (152,4 mm) long.15. Continue to tilt the engine until there is approximately 17 in. (431,8 mm) clearance. The crankshaft can now be removed. After assembly, check crankshaft deflection, see topic CRANKSHAFT DEFLECTION.

Tools required for engine lifting method of crankshaft removal:
Use extreme care in using this engine lifting method to prevent the cylinder block from falling.
This method of removing the crankshaft can be used where the tilting method cannot be used because of lack of over head and side clearances.1. Remove connecting rod and pistons as required.2. Place I beams (2) through inspection openings. On D379 Engines the beams should be placed through openings closest to the front and rear. Install 8F4225 Bolts, (six for D399 and D398 Engines and four for D379 Engines) in place of the bolts used to secure the block to the engine base to guide the block to raise straight.
TOOL ARRANGEMENT TO LIFT BLOCK FROM BASE (D399 Engine illustrated)
1. 2B9886 Hydraulic jacks (four). 2. I Beams (two) 8 in. (203,2 mm)-required length. 3. Guide pins (two). 4. Hoist.
Carefully block under the cylinder block to prevent it from falling.
3. Place blocking and jacks (1) under the beams.4. Raise the block to remove the oil pan base.5. The crankshaft can be removed with guide pins (3) installed in the crankshaft flanges and hoists (4) at the front and rear of the engine.
