Grinding the Arctic Cat Snowmobile Hood

Prior to adding resin and reinforcement to the Arctic Cat Snowmobile Hood, we need to grind the areas in need of repair.  Grinding will remove the damaged resin and glass, including problems from the past failed repair.  This allows us to bond new resin and fiberglass to the existing good material.  For repairs to be successful, proper bonding is extremely important.  Removing contaminants and loose/damaged glass, resin, and gelcoat is one of the most critical steps in assuring a successful repair. The repair will include both the inside and outside of the hood.  The inside is a structural repair and the outside is mostly a cosmetic repair. On the inside, I used a flat-disk right angle air grinder to remove the necessary material so that the repair could bond onto clean, original fiberglass. Proper safety precautions must be observed.  Gloves, glasses, and ear protection are all necessary.  Skin protection  is advised, as the dust can cause itching and irritation.  It is also very important to not breathe the dust. This is a messy job.  Lots of fiberglass dust is generated during the process of removing material to get down to a good bonding surface. These two corners of the snowmobile hood were cracked, repaired, and cracked again.  The grinding had to remove most of the failed repair and get down the bondable fiberglass.  It is important to remove shiny...

Failed Repair- Arctic Cat Snowmobile Hood

Snowmobile engine hoods are susceptible to damage.  The hood is at the front of the machine, which increases the likelihood for impact.  The hood covers the engine and is hinged to allow access.  This exposes the hood to engine heat and vibration.  There hood also experiences forces where it is attached to the hinge connection. This 1972 Arctic Cat Cheetah 440 snowmobile had seen damage across the front of the engine hood.  Cracked at the corners, the hood had been repaired with fiberglass and polyester resin in the distant past.  This old repair included 2-3 layers of plain weave cloth tape without any random strand fiberglass mat included in the layup. The original repair was a structural repair on the two corners of the hood leading away from the hinge attachment holes.  There had not been an attempt at any cosmetic repair to the front side. A damage survey like this only leads to one thing- a repair project! This can be repaired with a few basic tools and supplies.  Click here for the next...
