Never use the engine tilting group unless the base of engine is fastened safely to its foundation.
1. Remove the inspection covers from both sides of engine. Install 5B1181 Turnbuckles (5) with left-hand threads to top of engine. Put FT731 Left and FT735 Right Support Beams (9) and FT734 Supports (10) on their respective sides of engine. D398 and D379 Engines use FT113A and FT113 Support Beams.2. Install 8F4239 Blocks (1) and 8F4226 Yokes (7) on support beams (9). Tighten the 8F4230 Studs (6) 14.5 in. (368.3 mm) long into the 8F4226 yokes (7). Use the nuts on studs as shown.3. Turn the 5B1181 Turnbuckles (5) on studs (6). Turn 8F4231 Studs (4) 9 in. (229 mm) long into the turnbuckles.
The turnbuckles and studs must carry the engine evenly and must be turned evenly or restriction will be caused. If either turnbuckle is extra hard to turn, correct the restriction before proceeding. Turning with a force will cause damage to threads.
4. Turn the top of 8F4231 Studs in 8F4226 Yokes (3) and install 8F4239 Yoke, block (1), and FT736 Bracket (2) to the cylinder heads.5. Install 8F4225 Bolts (11), (six for D398 and D399 Engines and four for D379 Engines) in place of bolts used to hold cylinder block to oil pan base.6. Install steel plates or steel pipes as a support under the support beams (9). 7. Lift the engine four inches (102 mm) with the turnbuckles and install 8F4228 Hinge Yokes (12) and 8F4233 Hinge Blocks.
The engine must be kept level while it is lifted from the base. If an extra amount of effort is needed to turn one turnbuckle, or hinge block and holes do not have alignment, check the opening around the base with a scale. Make adjustments to keep the distance the same between cylinder block and base.
8. Install 8F4228 Hinge Yokes and 8F4233 Hinge Blocks between block and oil pan base. Use L1178 Bolts between yokes and base. Use bolts removed to hold hinge blocks to the block.9. Remove the 8F4225 Bolts used as a guide in Step 5.10. To tilt the engine turn the turnbuckles on both sides of the engine. When the ends of studs are even with inside base of turnbuckles, make a replacement of the 8F4230 Studs with FT111-A studs 20.5 in. (521 mm) long. Change studs one at a time.
If the ends of studs are extended farther than even with inside base of turnbuckles it can cause damage to threads of studs and in turnbuckles. If damage is caused to threads the engine can fail.
11. Tilt the engine until studs are extended the permissible distance. Remove 8F4231 Studs and make a replacement with FT733-5 Studs 11.5 in. (292 mm) long. Remove the FT111-A Studs and make a replacement with FT733-10 Studs (18) 23.5 in. (597 mm) long.
