Tech Bulletin: Reconditioning Camshafts

admin — Tue, 08 May 2012 15:46:24 +0000

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 visible inspection does not work and compromises this important aspect of engine performance and reliability.

At overhaul, camshafts must be reconditioned to restore lift, duration, and profile. Camshafts should also be inspected for inclusions, which can lead to failures after overhaul. Anything short of this leaves the engine vulnerable to major early life failures.

In an effort to focus attention on this area of the engine, B&G Machine has invested heavily in camshaft reconditioning equipment and engineering. With 800 masters, we precision-machine camshafts restoring them to their original profile.

Reprofiling the Camshaft Offers:

Restores the lobes to proper lift, duration and profile
Significant cost savings versus replacement
Better reliability and engine performance

Every camshaft is straightened to within .0005″, thus minimizing premature wear of the camshaft bearings. Additionally, precise surface finishes can be machined on the lobes while providing a fresh surface for the cam follower to function properly under the high unit lobe pressures and elaborate profiles.

Camshafts are often a weak link in today’s high horsepower engines. But after a B&G overhaul, this “Achilles Tendon” can be made to operate like new. We see the results with customers who consistently tell us they are getting better performance and longer life out of their engines.

Video: A Look at B&G’s World Class Block Department

admin — Tue, 17 Apr 2012 17:00:09 +0000

It says quite a bit about our reputation as an industry leader when you learn OEMs regularly come to us to help them develop proprietary repair strategies for their high horsepower diesel blocks. That’s because B&G Machine Engine Block Department is one of the most advanced facilities anywhere in the world. With six precision machining centers staffed by some of the best technicians you will find anywhere, we’re capable of completely reconditioning blocks as big as 4,000 horsepower.

Each block that arrives at our Seattle facilities goes through an initial test and inspection that identifies areas of stress and out of tolerance. Through the use of microprocessor controlled technology the block is then machined at every critical dimension to exact OEM standards. Finally the block is cleaned and inspected once again to ensure that it meets or exceeds not just the OEM’s, but our own high standards. Only once its passed B&G’s rigorous quality standards is it packed and readied for shipment.

It’s this sort of attention to detail that gives all our customers the confidence that every reconditioned block that leaves our facility will have a long, productive life in the field.

This week we’re pleased to present a short video that gives you a look at the men and machinery that make our Block Department truly world class. Click the video below to watch.

Repairing Water Erosion on Cat 3500 Blocks

admin — Wed, 04 Apr 2012 16:11:27 +0000

B&G’s non-corrosive desk insert process returns block to OEM specs

Water erosion on the deck of a 3500 Series engine blocks is common and leads to premature engine failure. Proper cooling system maintenance helps minimize exposure to this, but is generally not enough to prevent it.

Commonly found around coolant passages, severe water erosion ultimately leads to coolant leaks. With a proper repair strategy at overhaul, however, problem can be eliminated without sacrificing the integrity or life of the block. This will in turn deliver better overall reliability and long-term performance.

As one of the world’s most advanced re-manufacturing facilities, B&G Machine has developed an innovative solution to replace damaged coolant passages with new, non-corrosive inserts and restore the block to like new condition.

Installation of Non-corrosive Deck Inserts provides several advantages:

Eliminates future water passage erosion on the deck
Ensures Proper gasket and ferrule sealing
Delivers Long-term reliability

Using advanced programmable 3-axis CNC block machines, B&G technicians identify the location of these water passages. Each passage is then machined to allow proper press fit and non-corrosive inserts are installed and machined across all three axes. Finally, the entire block deck is surfaced for proper gasket sealing characteristics.

With six automated block machining centers capable of repeating to within .0001″, B&G Machine’s finished blocks always exceed OEM standards, which is why customers worldwide look to us as the premier solution for high quality and precision.

When it comes to high horsepower engines, thorough testing is a critical but often overlooked component of a long, trouble free service life. As leading experts in industrial engine reman, here at B&G Machine we understand this better than most, which is why we built one of the finest dynamometer testing facilities anywhere on the planet. Our dyno testing facilities are capable of handling diesel assemblies of 4,200 horsepower and 14,000 ft lbs of toruqe as well as gas assemblies of up 3,000 horsepower.

Every engine that enters our state-of-the-art center gets a complete top to bottom testing to verify horsepower, torque and all critical engine performance parameters. We also identify trouble spots such as leaks and injector issues. Each engine that leaves the facility also receives a digital printout data log of the engine’s actual performance, and the assurance that every detail has been addressed.

This week we’re pleased to provide a short video that gives you a look inside our testing facilities and provides a quick overview of our capabilities. To watch, just click the video below.

Putting it All Together: The Craft of Engine Assembly

admin — Tue, 14 Feb 2012 10:57:11 +0000

Tearing down, cleaning up and restoring a big diesel takes a skilled team and the right equipment

After nearly 60 years in the business, we tend to take the process of diesel engine remanufacturing for granted. It’s not until we have VIPs or a film crew standing in our facilities staring wide-eyed as we tear two tons of engine into a hundred pieces, restore each component, put it all back together and fire it up, that we’re reminded what we do is actually a carefully choreographed dance that very few can perform.

Each department at B&G is complete with state-of-the-art tooling and technology, and an expert staff to man it. This ensures that every engine re-build we perform — from the smallest grader to the largest haul truck — meets or exceeds manufacturer standards and delivers better reliability, longer up-time and lower operating costs across the board.

Of course, not everyone gets to come to Seattle to see our world class facilities or meet the team that makes us a leader in the industry. So this week we thought we’d share a brief video that takes you through the various departments and introduces the folks behind the magic that is a B&G reman engine. Just click the image below to watch.

If you’d like something a bit more brief, we’ve also got a timelapse video that collapses a complete engine assembly into just 20 seconds. Click here to watch.

We also have a full video library right here.

Balancing Act : Precision is Key to Long Engine Life

admin — Tue, 31 Jan 2012 18:00:59 +0000

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.

B&G Macine's State of the Art Balancer

One of the many things that sets B&G Machine apart from others in our industry is our continuing investment in advanced technology that helps us deliver superior results to our customers.

In 2009 B&G became the first to install a computerized balancing system complete with custom bob weights and tooling allowing us to test and balance crankshafts with unmatched precision.

Balancer's Computer Screen

This system, along with the experienced team of technicians here at B&G, has also allowed us to pioneer the development of new reconditioning and re-manufacturing techniques. Crankshafts with damaged or missing counterweights, counterweight pad fretting and other problems that might have once been considered total losses can now often be restored, reducing downtime and saving our customers dollars in the process.

Below is a brief video that introduces you to our balance department and state-of-the-art system. Please take a moment to check it out. And if you would like more information or a tour of our engine reman facilities, please feel free to give us a call. We will be happy to accommodate you.

A Happy 2012 from B&G Machine

admin — Tue, 17 Jan 2012 19:42:55 +0000

Greetings and welcome to 2012!

It’s a new year and with it we’ve got a lot of exciting stuff going on here at B&G Machine. If you haven’t been able to keep up on all the latest, last month we added a 6th block machining center capable of handling 4,000-plus HP engines, making us one of just a handful of industrial diesel reman facilities anywhere the world with this kind of technology and capacity.

A few weeks ago we also played host to a film crew from the Discovery Channel’s popular How It’s Made series for a couple of days while they shot an episode on what it takes to teardown and re-build a Cat 3516 from the ground up. The episode isn’t scheduled to air until this summer, but if you’d like to watch a mini version, we’ve got a timelapse video of our guys taking a 3524 from block to built in just over 120 seconds. » Click here to watch the video.

And speaking of video, since it’s a new year and all, we thought now was a good time to (re)acquaint you with the people and equipment that have helped make us an industry leader for the past six decades. Toward that end, we have a quick little minute an a half video called “Meet B&G Machine” that does just that. We hope you enjoy it and have a great 2012!

Photos from the How It’s Made Shoot

admin — Tue, 20 Dec 2011 18:05:14 +0000

In mid-December 2011, a film crew from Discovery TV’s Science Channel came to the B&G Machine facilities to film an episode of the network’s popular How It’s Made series.

With cameras rolling, over a two day period we took them through a complete reman of a Cat 3516 engine from top to bottom. Now that the filming is done it’s back to Discovery Channel’s studios for editing and voiceover to complete the episode, which is expected to air during the new season in the summer of 2012.

While, the air date is still six months off, we took a lot of photos of the shoot that we’d like to share with you now. (Once we’ve got an air date for the episode we’ll be sure to let you know.) Enjoy!
