How to Repair Case Paint
Damaged crankcase or transmission paint may leave a bare spot of aluminum that ruins the overall looks of the powertrain. At the Motor Company’s 2001 New Model Announcement the Customer Service department demonstrated a simple procedure for repairing case paint in the field. For those of you who missed this valuable demonstration, this “How To” article is provided.
Tools & Supplies
You’ll need some basic tools to complete this repair procedure.
• Scraper
• 100 & 180 grit sandpaper
• Harley-Davidson Texture Black paint (P/N 98606-BF), Silver Bead Blast paint (P/N 98606-BY), Granite High Temp (P/N 98606CTN – ’08-later CVO) or Medium Gray High Temp (P/N 98606CPM – 1200N)
• Newspaper
• Heat gun
Step 1
Scrape off any loose paint from the damaged area
Step 2
Sand the aluminum with 100-grit sandpaper and feather the edge of the paint with 180-grit sandpaper
Step 3
Create a funnel with a newspaper to direct the lightest possible spray of the appropriate paint to the damaged area. (Note: Remember to paint in a properly ventilated area.)
Step 4
Use a heat gun to dry, not bake the paint. Repeat steps 3 and 4 several times to create a seamless repair. (Note: Please follow instructions
and warnings for heat gun use.)
