Component Parts – 2008 & Earlier WSM 18.5″

In this topic:

Here are photos and detailed descriptions of all the parts that make up the Weber Smokey Mountain Cooker for model years 2008 and earlier.

For part numbers and a diagram showing the relationship between parts, visit the Parts Schematics For Weber Smokers page. To see how a WSM is put together, visit the WSM Assembly page.

Three Major Sections

Assembled height: 41″
Assembled width: 19″
Assembled weight: 37 pounds

Three Major SectionsThe Weber Bullet has three major sections:

  • The Lid
  • The Middle Cooking Section
  • The Charcoal Bowl

When these three sections are fitted together, they achieve a fairly good seal—not airtight, but a good seal. This is one of the secrets of the WSM’s ability to regulate and maintain temperature easily. The sections come apart for easy cleaning and transportation.


18.5″ OD x 13″ (including handle)
3″ damper (1), 0.75″ holes (3 per damper)
10.5″ between inside top of lid and top cooking grate

The lid is constructed of heavy-gauge steel with a porcelain enamel finish inside and out. It is fitted with a handle and an adjustable vent damper.


The handle is made of gray, heat-resistant nylon plastic and has the Weber logo stenciled on it. Prior to 2000, handles were made of wood.

Thermoset lid handle

The vent damper exhausts smoke and heat from the cooker, allowing them to pass over your food for that great barbecue taste. Most WSM owners leave this vent completely open at all times during the cooking process, since inadequate ventilation can cause an off-taste in foods. It may be partially closed if the cooker is running much hotter than desired, and should be completely closed at the end of a cooking session to extinguish the coals.

Lid Vent

The damper is made of rust-resistant aluminum and is fastened to the lid with a 1/4″ aluminum tubular rivet. The two tabs are used to grasp the damper to adjust it, and each damper hole has a stop tab that limits the open/close motion of the damper. There is also a two-character date of manufacture code stamped into the damper.

Middle Cooking Section

18.75″ OD / 17.625″ ID x 17.5″
7.25″ x 10″ access opening, 6″ between screw holes

The middle cooking section is constructed of heavy-gauge steel with a porcelain enamel finish inside and out. It holds two grates where all the cooking action takes place, plus the water pan and the access door through which fuel, smoke wood, and water are added during the cooking process.

Middle Cooking Section

The water pan and cooking grates rest on four grill straps that are fastened to the inside of this section. This photo shows two of the holes used to attach a grill strap.

Charcoal Bowl

18.5″ OD x 10″ (without legs), 12.375″ (with legs)
3″ damper (3), 0.75″ holes (3 per damper)

The charcoal bowl is constructed of heavy-gauge steel with a porcelain enamel finish inside and out. It contains the charcoal grate and charcoal chamber in which the fuel and smoke wood are placed. The bowl sits on three sturdy aluminum legs that provide a stable base for the cooker.

Charcoal Bowl

There are three adjustable vent dampers in the charcoal bowl. These dampers are identical to the one in the lid. Each vent damper is adjusted independently throughout the cooking process to control air flow into the charcoal bowl. By increasing or decreasing air flow, fuel combustion is increased or decreased, thus raising or lowering the cooker temperature. Each damper may be fully open or fully closed or somewhere in-between depending on the need to control cooker temperature.

Closing these three dampers and the lid damper at the end of a cooking session will extinguish the coals.

Cooking Grates

Top: 17.5″ diameter, 240.5 square-inch surface
Bottom: 17″ diameter, 227 square-inch surface
7.5″ between top and bottom grates

The Weber Bullet has two nickel-plated cooking grates with a combined surface area of approximately 468 square inches. The grates are supported by four grill straps fastened to the inside the middle cooking section.

The top grate has two handles and is situated near the top of the middle cooking section. It is the same grate used in all Weber 18.5″ charcoal grills.

Top Cooking GrateThe bottom grate is slightly smaller in diameter, has no handles, and is situated 7.5″ below the top grate. The smaller diameter is necessary to provide clearance between the grate and the grill straps.

Bottom Cooking Grate

Water Pan

14.75″ OD x 3.25″
9.75″ between bottom of pan and charcoal grate
1/2″ between top of pan and bottom cooking grate
1 gallon capacity

The water pan is constructed of heavy-gauge steel with a porcelain enamel finish. The water moderates the temperature of the cooker, provides a moist cooking environment, and catches any drippings, preventing them from flaring-up on the hot charcoal below.

Water Pan

The pan is supported by the same grill straps that support the two cooking grates.

Charcoal Grate

15.25″ diameter
4.5″ between grate and bottom of charcoal bowl

This grate rests in the bottom of the charcoal bowl on the three screws that attach the legs to the bowl. It holds the charcoal chamber into which the fuel and smoke wood are placed. Ashes fall through the grate to the bottom of the charcoal bowl.

Charcoal Grate

Charcoal Chamber

14.5″ OD x 4.75″

The charcoal chamber is constructed of heavy-gauge steel with a porcelain enamel finish. It is placed on top of the charcoal grate and keeps the fuel centered on the grate and prevents the dampers in the charcoal bowl from becoming blocked. The perforations provide airflow to the burning coals and smoke wood.
