Balancing Act : Precision is Key to Long Engine Life

Engine balancing is an important part of any engine re-build, and a critical component in the high horsepower diesel reman process. Because these engines run for extended periods under load and often in harsh conditions, precision balancing is key to minimizing vibrational fatigue and extending the equipment’s operational life. One of the many things that… [continue reading]

Engine Components: OEM Exchange Programs vs. B&G Reman Exchange

Any time you exchange an engine component you lose control of your core — and perhaps the optimal life and performance of the engine. OEM exchange programs are convenient, but there is a downside — the product that you get back might not be what you really want. With a B&G Reman component critical specifications… [continue reading]

Alignboring Cylinder Blocks

Printer friendly version Throughout the life of an engine, the mainline has a number of different stresses, chief among them torsional fatigue and heat. Properly inspecting the mainline requires a dimensional measurement for size as well as alignment. The latter is often overlooked. One of the key advantages of B&G’s mainline reconditioning services is that… [continue reading]

Cylinder Heads: Custom Rebuild Versus Exchange

Printer friendly newsletter Cylinder heads play a fundamental role in extending the service for the top end of your engine. Proper machining, coupled with new valvetrain parts replacement, produces a head that performs better and more reliably. Custom machining your cylinder heads (versus exchanging with an OEM program) has benefits that give you more control… [continue reading]

Tech Bulletin – Water Erosion, Cylinder Blocks

(Click here for a printer-friendly version of this bulletin) Water erosion on the deck of 3500 Series engine blocks is common and leads to premature failure. Proper cooling system maintenance helps minimize exposure to this failure mode, but is often not enough. A strong repair strategy at overhaul can eliminate this risk for the life… [continue reading]

Tech Bulletin – Camshaft Reconditioning

(Click here for a printer-friendly version of this bulletin) Today’s high horsepower electronic fuel injected engines demand an overwhelming amount of performance from camshafts. Ironically, camshaft reconditioning or replacement is often overlooked at overhaul. Again and again, we hear about mid life camshaft related failures after overhaul. Qualifying a camshaft for reuse with a simple… [continue reading]

Tech Bulletin – Connecting Rods, Cylinder Packs and Balancing

(Click here for a printer-friendly version of this bulletin) In a recent technical bulletin, we discussed the importance of crankshaft balancing and how it directly improves the service life of the engine and related components. This week, we are adding emphasis to that by focusing on the importance of balancing the cylinder packs. Balancing produces… [continue reading]

Tech Bulletin – Crankshaft Balancing

(Click here for a printer-friendly version of this bulletin) In August 2009, a new deck height dimension was specified for CAT 3500B model engines (Ref. CAT SIS #SEBF8157). This specification calls for a higher deck height meaning the same cylinder blocks that once passed inspection are now out of spec due to low deck height…. [continue reading]
