REMOVAL

WARNING

Eye protection is required when performing drilling operations. Failure to do

so may result in injury to personnel.

Drill three evenly spaced 0.161-in. (4.1-mm) diameter holes in rear seal (2).

Alternating between drilled holes, use slide puller with adapter to evenly remove rear seal (2) from

cover (1). Discard rear seal (2).

NOTE

Wear sleeve will be present on crankshaft only if rear seal was previously

replaced.

If present, remove wear sleeve (3) from crankshaft (4).

CLEANING AND INSPECTION

WARNING

Skysol-100 mixture is combustible. Use mechanical ventilation whenever

product is used in a confined space, is heated above ambient

temperatures, or is agitated. DO NOT use or store near heat, sparks,

flame, or other ignition sources. Keep container sealed when not in use.

Contact with Skysol-100 may cause skin irritation. Use chemical resistant

gloves. In case of skin contact, remove any contaminated clothing and

wash skin thoroughly with soap and water. Wash contaminated clothing

before reuse. Eye contact may cause irritation, tearing, or blurring of

vision. Use face shield or goggles when eye contact may occur. In case of

eye contact, flush eyes with large amounts of water for at least fifteen (15)

minutes or until irritation subsides. Inhalation may cause irritation to

upper respiratory passages. DO NOT have food or drink in the vicinity.

Using Skysol-100, clean rear of crankshaft (4) and cover (1), and dry with lint-free cloth.

Inspect cover (1) for cracks, breaks, and gouges. Replace cover (1) if cracked, broken, or gouged.

INSTALLATION

NOTE

Tighten locator screws only finger-tight so that when seal and seal sleeve

are installed they will self-align.

Install locator on rear of crankshaft (4) with two locator screws.

CAUTION

Rear crankshaft seal must be installed with wear sleeve in place. Do not

remove wear sleeve from rear crankshaft seal. Failure to comply may result

in damage to equipment.

Position new rear seal (2) on seal sleeve with beveled edge of wear sleeve (3) facing toward locator.

Install rear seal (2) and seal sleeve as a unit over locator and tighten two locator screws.

Position seal installer over locator, seal sleeve, and rear seal (2) and finger-tighten nut assembly.

Tighten nut assembly to install rear seal (2) on crankshaft (4) and cover (1).

Remove nut assembly, seal installer, and seal sleeve from locator.
