Question 1 of 27070

The insertion of shims between the foot of a marine type connecting rod and a bearing box would result in __________.

🔍 Key Concepts

• How adding shims affects the distance between the crankshaft and piston travel at top dead center (TDC) • Relationship between connecting rod/bearing fit and bearing clearance • How (or if) changes at the bearing box end affect compression ratio in a diesel engine

💭 Think About

• Does inserting shims move the bearing cap closer to or farther from the crankshaft journal? Visualize a cross‑section of the crank, bearing, rod foot, and shims. • If the centerline of the crankshaft relative to the piston changes, what happens to piston travel at TDC and the clearance volume in the cylinder? • Would adding shims tighten up the bearing on the journal or loosen it? How does that relate to the oil film space (bearing clearance)?

✅ Before You Answer

• Be clear on whether shims increase or decrease the space where the bearing and crank journal meet. • Decide if the modification is at the bearing interface only, or if it significantly alters the compression space above the piston. • Mentally compare the effect of shimming to line‑boring or machining a bearing cap: does it normally correct too‑tight or too‑loose clearances?
