what is the difference between an oversized rod bearing and an undersized rod bearing?
442640
The outside diameter of the bearing is what fits into the engine block, and the crankshaft rests on the inside diameter. An oversized bearing has the same inside diameter but a bit more material on the outside diameter. An undersized bearing measures the same outside but is thicker on the inside.

Whitworth thread is coarser than a BSF of the same diameter,but the same spanners are used on both ranges,and are often marked with both Whitworth and BSF sizes . A whitworth spanner or socket is larger than one marked with the same size in BSF for example a 1/4 inch whit is the same physical size as a 5/16inch BSF.

There is no difference between the skateboard and longboard bearings. Regardless of the size of your wheels or type of skating you do, street skate or longboard, the bearings are the same size. ... A common overall width for skateboard bearing spacers is 8 mm, while for larger longboard wheels you'll need a 10 mm spacer.

The key difference is in how the two thread into the bottom bracket shell. ... The width of the bottom bracket shell is also different; BSA bottom brackets are usually 68mm or 73mm wide, while Italian threaded bottom brackets come in at 70mm wide. Both standards use a 24tpi pitch thread.

Undersize bearings have more metal on the inside of the shell meaning a smaller diameter internally when the 2 shells are put together. Used when the crank is ground down. Oversize have more metal on the outside and thus an increase in the ouside diameter.

Basics. A completed bearing is like a ring; it has an outside diameter and an inside diameter. The outside diameter of the bearing is what fits into the engine block, and the crankshaft rests on the inside diameter. ... An undersized bearing measures the same outside but is thicker on the inside.

Accordingly, higher ABEC ratings demonstrate more precision of ball bearings. ABEC 11 products (labeled as ABEC 9) works with higher efficiency than those ABEC 5 or 7 products. They give an awesome ride on small cracks, gaps, and rocks on the surface with minimal vibration.

A grommet that is 1/4 inch larger than the rod diameter slides smoothly along the rod. For example, a common 1 5/8-inch grommet glides over a 1 3/8-inch diameter rod.

An 18-gauge fastener is smaller than 16-gauge. This is pretty important to keep in mind because the basic choice it presents is whether you want a fastener that leaves a smaller hole to fill or a bigger fastener in the wood.

No, No and No. Commodores are metric, and HQ-WB hubs are Imperial (inch) measure - and never should the two be mixed. Not only is the wheel stud PCD different, the Commodore studs (and therefore the wheel rim holes) are bigger diameter (12 mm), than HQ studs (7/16" or 11.1125 mm).

The 1310 series u-joint measures approximately 3 1/4 inches wide. The 1330 and 1350 both measure approximately 3 5/8 wide. ... The 1350 series has a cap diameter of 1 3/16 inch and the body and journals are bigger than the 1310 or 1330. Remember 1350 is almost never found in production car driveshafts.

No, they aren't all the same. The LB7 and LLY ('01-'05 MY) use the same block. ... The LBZ/LMM and LML blocks are supposed to be stronger, but a lot of race builds use and LB7 block for whatever reason. Most parts on the Duramax engines are interchangeable.

Moderator. SE and SER are both allowed in raceways. If you need to use an LB it will have to be large to accommodate the required bending radius.

No they are not the same at all. Different size jets, oumps and there was even different cfm. Normal is 750 cfm and I think it was 800 or 830 was the bigger one. Check with Lars on this.

2 RS - Bearing with rubber seal on both sides. RS provides a better seal but more rolling friction than 2Z. ... 2 Z / ZZ - Bearing with a metal seal on both sides. Z - Bearing with a metal seal on one side, one side open.

Saltwater rods are generally thicker and heavier compared to their freshwater counterpart. For the most part, they are longer as well for longer casting.

For most cars, 1310-series U-joints are typical choice, but for performance applications, the rugged 1350-series joints are the better choice. The larger the series number, the larger the trunnion. Trunnions are the protruding shafts that the caps ride over. Larger trunnions equate to more torsional strength.
