Kenworth T880 "LONG" Hood Repair Kit

THIS IS IMPORTANT:

This kit only fits the T880 with the "LONG" hood. It does NOT fit the "short" hood.

Compare your hood to the image below. If you have a "short" hood, this will NOT fit your hood.

The damage to Kenworth T880 Metton hood pockets is very common. An OEM Kenworth T880 LONG hood will set you back at least $5,000. Even an aftermarket fiberglass Kenworth T880 LONG hood costs about $2,500. Polyvance has a much more economical solution to repair the damaged Kenworth T880 hood pockets. Polyvance's Kenworth T880 LONG Hood Repair Kit will allow you to repair the damaged hood pockets on your Kenworth T880 for a fraction of the cost of replacing your damaged Kenworth T880 LONG hood. Polyvance's Kenworth T880 LONG hood repair kit allows the user to repair the broken, strut-bracket mounts on Kenworth T880 LONG Hoods. These strut-bracket mounts seem to break easily. Rather than spending thousands on a new hood, Polyvance created the Kenworth T880 LONG Hood Repair Kit which repairs and reinforces the broken strut-bracket mounts. The cast aluminum strut-bracket mounts are screwed and bonded into place with the included PlastiFix high-performance methacrylate adhesive.

Benefits:

• Save thousands over the cost of a new hood.
• Repairing the hood is faster than replacing the hood.
• With the Kenworth hood repair kit, there is no need to paint the hood. Replacing the hood requires you to paint the hood to match.
• Stronger than the original hood pockets. Load is spread out over a much larger area.
• Usually faster delivery times. Definitely cheaper shipping cost.
• Better design. If you replace the hood, you are putting on a new hood with the same poorly-designed hood pockets that will probably break again. The Kenworth hood repair kit is a better design as it converts the point load to a large-area load.
• This kit will get your truck back on the road quickly so you can continue making money. Every day that your truck is not on the road, you are losing money. Stop losing money. Repair your hood this morning and continue making money this afternoon.

Step-By-Step Instructions (Click Images to Enlarge Them)

Step 1

Clean the area to be repaired with soap and water, then 1000 Super Prep or 1001-4 EcoPrep to remove all contaminants from the surface. Gently force dry the area with a heat gun if necessary.

Step 2

Measure approximately 1” up from the flat surface of the hood and draw a cut line all the way around the strut mount bulge.

Step 3

In a well-ventilated area, use a rotary tool with a cut off wheel to remove the top of the bulge.

Removing the top of the bulge provides clearance for the reinforcing ribs on the repair plate to clear the hood, allowing the plate to be fully seated onto the hood’s surface. The 1” (2.5 cm) wall provides extra bonding area between the plate and the hood.

Step 4

Test fit the plate to be sure it can be fully seated onto the hood. It should be snug, but if it does not seat with moderate pressure, trim a little more of the hood away until it can be fully seated.

Step 5

With the reinforcing plate on the hood, trace around it with a permanent marker to mark the area to be sanded.

Step 6

Sand the hood’s surface with 25 to 60 grit sandpaper on a Roloc® disk to remove the paint and any oxidized plastic. Sand until the area inside the traced line shows 100% fresh, sanded plastic. Hand sanding may be required in some areas due to the complex shape of the hood.

Step 7

Aggressively sand the inside surface of the aluminum reinforcement plate with 25 to 60 grit sandpaper on a Roloc® disk. Sand every surface that will touch the hood until the sanding scratches have 100% coverage. It’s very important to leave no unsanded surface where adhesive will be applied on both the plate and the hood. Hand sanding parts of the reinforcing plate will also be required in this step.

Step 8

Place the reinforcing plate back on the hood and double check the fit. Make sure the plate can be fully seated over the entire surface and there are no large gaps at the edge of the plate where it meets the hood. PlastiFix is a very strong adhesive and will work well filling gaps up to about 1/8” wide, so perfection isn’t needed. If there are large gaps, further trimming of the hood may be required to clear the aluminum reinforcing ribs.

Step 9

Once confirming the reinforcing plate can be fully seated, use the plate as a guide for marking the 6 locations for drilling 9/64” holes. The plate itself can be used as a drill guide, or drill at the marks as we have done here.

Step 10

Before bonding the reinforcing plate to the hood, install the OEM bracket onto the reinforcing plate using the included 1-3/4” bolts, flat washer and lock washer, with the fork facing the large side of the bulge. A few drops of low strength thread locker on the bolts is recommended to reduce corrosion of the bolt in the threaded hole.

Step 11

Blow the dust off the mating surfaces and clean a second time with 1000 Super Prep or 1001-4 EcoPrep. Wipe dry with a clean dry cloth. Make sure the surfaces are completely dry before proceeding to the next step.

Step 12

Apply a generous amount of adhesive to the surface of the sanded area on the hood. Use a body spreader to cover the entire area.

Step 13

Apply an even larger amount of adhesive to the reinforcing plate, zig-zagging across entire sanded surface.

Step 14

Place the reinforcing plate onto the hood. Secure it using six (6) #10 x 1 screws. Gently snug the screws when first installing them. Making them tight immediately can cause uneven distribution of the adhesive and may cause the plate to be seated improperly. Tighten the screws in a star pattern, the same way you would tighten lug nuts on a wheel, until an even bead of adhesive squeezes out along the perimeter of the plate. Do not over-tighten. If there are any gaps after the screws are tight, squeeze more adhesive into the gap until its full.

Step 15

After curing a minimum of 4 hours at room temperature, or 24 hours for full strength, it’s safe to attach the hood struts. Be sure the hood struts are functioning properly before mounting them, as this is typically the reason the mounts failed in the first place.
