The bolt circle diameter is typically expressed in mm and accompanies the number of bolts in your vehicle's bolt pattern. One example of a common bolt pattern is 5x100 mm. This means there are 5 bolts evenly spaced about a 100 mm bolt circle. The picture to the right is an example of a 5×100 mm bolt pattern on a Subaru BRZ. The wheel has 5 lug ...
Many Wrangler owners will have up to two inches removed from the bottom of the 10.5" 14-bolt differential housing to maximize ground clearance. [9] The popularity of GM trucks and vans made 10.5" 14-bolt axles a common sight in junkyards, making them an option for vehicle customization projects, including buggy builds and even classic trucks.
Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.
On steering wheels for cars utilizing bolt circles, this usually measures 6×70 mm. [3] Some racing wheels attach to the car via a quick release hub, [4] and this hub then usually has a corresponding bolt circle of 6×70 mm. Example of other less used patterns include: 3×1.75 in (44.45 mm), 5×2.75 in (69.85 mm), 6×74 mm and 6×2.75 in (69.85 mm).
Example (inch, fine): For 7 ⁄ 16-20 (same diameter as the previous example, but this time with 20 threads per inch, which is considered fine), 0.437 in × 0.90 = 0.393 in (i.e., if the threads are to be fine, then a slightly larger diameter drill bit should be used before tapping the hole for the screw).
In 1996, a bolt-on bell housing was phased in (along with a six-bolt tailhousing) for S-10 Trucks and S-10 Blazers and beginning in 1998 for all other applications. Beginning in 1998 a new 300mm torque converter with improved higher-capacity internals, 300mm style input shaft, and 300mm style pump was also introduced on models coupled to a Gen ...
Pontiac's 215 cu in (3.5 L) (1964–1965) was a smaller bore of 3.75 in (95.25 mm) version of the 230 cu in (3.8 L) Chevrolet straight-six engine. One oddity is the crankshaft bolt pattern; in lieu of the Chevrolet V8 bolt pattern (also shared with the rest of the third-generation six), the Pontiac V8 bolt pattern is used.
