 TM 55-1905-223-24-1
NOTE
The part number is on the same side as the bevel.
(f) Place the ring gear (2) over the flywheel (3) while still hot. Install ring gear so the bevel is positioned
toward the crankshaft edge of the flywheel.
CAUTION
Allow air to cool the gear. Do not use water or oil to reduce the cooling time. Damage to the
gear can result.
(g) Place flywheel and ring gear assembly (1) aside to cool.
(4) If cracks or other defect are found in the flywheel (3), replace with a new component.
b. Barring mechanism (FIG. 4-73).
(1) Check the barring mechanism gear (2) for worn or broken teeth.
(2) Check the spring (1) for adequate tension.
(3) Check the shaft (5) for evidence of wear or other physical damage.
(4) Disassemble barring mechanism, if required.
(a) Remove retaining clip (6).
(b) Push shaft (5) in and remove gasket (4).
CAUTION
Do not attempt to push shaft out without spacers or supports between the gear and the housing.
The woodruff key will damage the housing.
NOTE
1/8-inch steel pipe couplings may be used for the supports (3, FIG. 4-74).
(c) Place supports (3) between the gear (2) and the housing (4). The supports must be a minimum of
13/16 inch (21 mm) long to allow the key (5) to clear the gear (2) and not contact the housing (4).
(d) Use an arbor press and mandrel (1) to push the shaft until the key (5) is exposed. Remove the key
(5) and the supports (3).
(e) Remove shaft (5, FIG. 4-73), spring (1), gear (2) and retaining ring (8).
(f)
Clean the parts and inspect them for damage.
