Clean Parts

Ground and Polished Parts
NEVER use hot solution tanks or water and alkaline solutions to
clean ground or polished parts. Damage to parts can result.
• NEVER clean ground or polished parts in a hot solution
tank, water, steam, or alkaline solution to avoid damaging
the surfaces.
• Use a cleaning solvent to clean ground or polished parts or
surfaces. NEVER USE GASOLINE.
• Use a knife, if required, to remove gasket material from
parts. Be careful not to damage the ground or polished
surfaces.
Clean Rough Parts
• Clean rough parts with the same method as cleaning
ground and polished parts.
• Use a cleaning solvent or a hot solution tank with a weak
alkaline solution to clean parts with a rough finish.
• Leave the parts in the hot solution tank until they are
completely cleaned and heated. When the parts are clean,
remove them from the tank.
• Wash the parts with water until the alkaline solution is
completely removed.
Clean Transfer Case Assemblies
Close or cover all openings, including breather, oil drain, and
speed sensor, before steam cleaning. Steam can cause compo-
nent damage.
• Steam clean transfer cases on the outside to remove heavy
amounts of dirt.
• Before steam cleaning the transfer case, close or put a
cover over all openings in the case.
• Remove any remaining silicone sealant from the transfer
case halves using a suitable scraper or wire wheel.
