What is a rod cap?

A rod cap is the removable section of a two-piece connecting rod that provides a bearing surface for the crankpin journal. The rod cap is attached to the connecting rod with two cap screws for installation and removal from the crankshaft.

What is a bearing cap?

Bearing caps contain the main bearings of an engine’s crankshaft. As part of their required processing, bearing caps must undergo a tough splitting operation, requiring strong and stable operations. Tooling for bearing cap machining is highly complex and often custom in nature.

What is the reason for marking the connecting rod and cap before removing the cap?

Since the caps are matched with their corresponding connecting rods, it’s essential to keep the caps in order during disassembly. That’s why, if no number is stamped, a mark with the cylinder’s corresponding number is made by the technician.

Are bearing dust caps necessary?

Grease caps protect your wheel bearings from the dirt, dust, sand, water, salt and road grime that can (and will) destroy bearings. Without grease caps, your wheel bearings simply wouldn’t survive for very long out on the road. Bearings require constant lubrication to remain effective.

What holds the bearing cap in place?

The lower half of the main bearings are typically held in place by ‘bearing caps’ which are secured to the engine block using bolts.

What tools are needed to remove press fit piston pins?

Universal Piston Pin Press-Out Tool (PPE-1) A universal tool set to use with your shop press, this tool is made of high quality steel and is sized to work with most applications. This set is for basic removal of pins without damage to the piston.

Which tool is used to remove the piston ring?

Always use piston ring pliers for mounting and dismantling piston rings. Other tools, such as wire loops or screwdrivers, damage the piston ring and the piston. Never pull on the rings by hand (exception: steel cup segment type double bevelled oil control rings).

What are connecting rod caps and connecting rods and rods?

Connecting Rods and Rod Caps. Connecting rods and their matching caps are fastened to the engine’s crankshaft to convert linear motion into rotary motion. They are often constructed together as one piece. Then a process of breaking the cap away from the rod is done at the factory. Connecting rods and caps must remain a matched set.

Can I mark the caps with the rods of the engines?

Marking the caps with their corresponding rods is done only when necessary. Making an indentation on a connecting rods shaft is a terrible idea. These rods are made of durable metals and often hardened to retain their strength as the engine wears. Even scratching into one of these rods will weaken it, and could end in catastrophe.

What happens if there is no number on the connecting rod?

Connecting rods and caps must remain a matched set. Since the caps are matched with their corresponding connecting rods, it’s essential to keep the caps in order during disassembly. That’s why, if no number is stamped, a mark with the cylinder’s corresponding number is made by the technician.

What to do with a rod protruding from the engine block?

Most of us have seen a thrown rod protruding out of someone’s engine block. Only mark them if you have to; the base is a good spot. After removal, screw the nuts onto the bolts to keep the two parts together.
