Connecting Rod Reconditioning This step of the engine rebuilding is important the fact that the rod is part of the motion of the engine. After cleaning and then crack checking and straightening the rod we then machine the parting faces of the rod making the bearing end smaller. We then install new rods bolts and then torque to recommended spec.
Aug 20, 2001· RE: Machining connecting rod big ends. AndyA (Marine/Ocean) 20 Aug 01 14:01 Nazeer is correct, the engine manual will have the limits for machining and should also give part numbers for the oversized brgs that correspond to new size of big end.If not get in touch with B&W and get an up to date manual for it.
This will be the big end of the rod. Move 1.850" toward the opposite end of the rod and drill a 1/4" hole for the small end. then, using a 1/2" center-cutting end mill, drill the 2 holes for the big end side radius. Next use a 1/4" ball end mill and hollow out the side of the rod. Then use a standard 1/4" end mill to cut the sides of the rod.

Assuming that JLMCCUAN's rods (or a similar set of rods) don't appear I've done the math on the various different combinations of parts. I'm only shooting for 350hp right now but with good pistons and crank, I'd rather not spend significant money on something with only half the power capacity in the middle of them and kill the good parts.

Oct 06, 2013· Connecting Rods The big end of the connecting rods that clamp around the crankshaft need to be checked for sizing. Some connecting rods have floating piston pins, the bushings will need to be checked for play and wear as well. As a rule of thumb, it's best to replace the rod bolts.
Nov 18, 2007· Your balancing shop can employ one of several different methods in which to reduce the connecting rod end weights. Typical tools for this operation can vary from using a grinder, belt sander, or a milling machine.

To that I would add squareness as a major concern. Without a jig to guide the reamer Let's say I sweep a dial gauge in my drill press chuck on the machined face of the conrod big-end bore (same way you tram a mill). Assuming this machined face is square to the big-end bore, I can adjust my drill table to get the rod square to the quill.
Next the con-rod was returned to the 4-jaw chuck and the bevel side faces were turned. The 2.5mm through hole drilled in the big-end bearing meant that set up was easy and it ran true from the outset. When the con-rod was clamped on the crank-pin for the first time it was a little tight although could be rotated with some force.

Nearly all high-performance connecting rods are manufactured from high-strength 4340 alloy steel. Most high-performance steel connecting rods are manufactured from a forging. Despite the simple appearance of a connecting rod, its forging will actually go through nearly twice the number of operations as a performance piston.
Hello again everyone!! This episode I plan to get a lot done, starting off with finishing the connecting rod. Last time I was able to machine the "big-end" of the rod and now I must finish the wrist pin end. I started off by leveling the rod on the table so the yoke could be bored for the wrist pin. I lined up the mill .
Nov 10, 2012· The LeBlond rod boring machine uses a vertical slide + the cross slide to get the big end centered about the spindle. A home made setup will not have this vertical slide. If this setup is it be built for only one engine's rods, a fixture relying on shimming to center the big end in the vertical direction may be all that is needed.
A connecting rod for an internal combustion engine consists of the 'big end', 'rod' and 'small end'. The small end attaches to the gudgeon pin (also called 'piston pin' or 'wrist pin'), which can swivel in the piston. Typically, the big end connects to the crankpin using a plain bearing to reduce friction; however some smaller engines may instead use a rolling-element bearing, in order to ...
