Navistar: The changing face of MaxxForce

Could Navistar International be heading towards dropping its mid-range diesel engines following a quiet rejig of its nomenclature?

Navistar chooses Tremec ‘box for ProStar

In an unusual move, Navistar International is to offer the Tremec light-weight 10-speed manual transmission teamed with the 13-litre MaxxForce diesel in its International ProStar model.

Navistar will also offer Tremec  transmissions as an option in ProStar units powered by the Cummins ISX15 engine.

MAN 15-litre CGI diesel cuts weight

As German truck maker MAN establishes closer ties with fellow VW stablemate Scania through shareholding and heavy truck transmission technology, it also appears to have moved the goalposts with its newly-developed 15.2-litre, six-cylinder in-line D3876, the latest of the company’s Euro 6 range of engines.

With torque figures of 2500 to 3000Nm and power outputs of 520 and 560bhp for long distance and towing vehicles, or 640bhp for heavy goods vehicles, the D3876 is the company’s top model and offers a 160kg weight-saving over a Euro 5 unit.

Navistar sets aside $1.38bn for warranty claims

According to Troy Clarke, chief executive officer of Navistar International Corporation, the OEM has “capacity” to satisfy warranty claims by using a balance-sheet reserve of $1.38 billion dedicated to warranty work.

In an item published in the 14 July 2014 issue of Transport Topics, following an interview with Transport Topics editors and reporters, Clarke said that part of the company’s turnaround includes working through a backlog of warranty claims made against the company’s MaxxForce engines made from late 2010 and into 2012 — before Clarke became chief operating officer.

MaxxForce engine problems?

A recent advertisement in Transport Topics offered some interesting reading.

Attorneys at law, Miller Weisbrod LLP of 11551 Forest Drive, Dallas, Texas raised a number of questions in their advertisement under the headline: MaxxForce engine problems?

Clarke to head Navistar as CEO

Troy Clarke has been appointed chairman and chief executive officer (CEO) of Navistar International Corporation.

Clarke assumes responsibility on 15 April when he replaces Lewis Campbell, 66, chairman and interim CEO since last August. Clarke has been president and chief operating officer of Navistar.

Campbell withdrew from retirement from Textron Inc. to assume the senior post at Navistar. Campbell’s role has been to define a new course for the company and Clarke’s role has been to implement these changes.

Navistar Big Bore engines to restart in 2013

Navistar International Corporation expects to announce this month the date of start of production (SOP) of its Big Bore engines that have been found to be non-compliant with US Environmental Protection Agency (EPA) regulations.

The US engine builder has been forced to halt production of MaxxForce 13 and 15 diesel engines following the EPA’s decision to oppose the company’s type of engine emissions technology.

So, in an embarrassing about-face, Navistar will adopt SCR technology and is working closely with Cummins to resolve its current issues. Navistar, based in Lisle, Illinois, has opposed SCR technology for years and is now paying the price.

Navistar has come to a long-term supply agreement with Cummins Inc. of Columbus, Indiana to use its heavy-duty diesel engines and “emissions after-treatment systems” for Big Bore engines.
