PME Offers Eight-Page Brochure On Babbitt Bearing Repair Service Plant Maintenance Engineering (PME) of Cincinnati, Ohio, is offer- ing a free eight-page brochure that covers the services offered by PME with regard to their babbitt bearing repair service. The brochure covers PME's capa- bilities (babbitt, centrifugal casting, static pouring, metalizing, and tig welding) and discusses the differ- ence between merely pouring bab- bitt in a bearing, and completely repairing, refurbishing and preci- sion machining a babbitt bearing. Additional capabilities are listed as mechanical cast iron repair, com- plete field machining, and in-house apparatus service. Under the heading "PME is at your service," the publication lists the addresses and phone numbers of PME's babbitt bearing repair cen- ters, which are strategically located throughout the U.S. All of their facilities are equipped and staffed to meet the needs of their custom- ers. PME's plants are available 24 hours a day, seven days a week for around-the-clock service. ; General maintenance tables are included that list babbitt composi- I tion and give recommended clear- ances for babbitt bearings.

The DOT // PC rep- resents the third generation of Me- l gasystem engineered combustion > January, 1988 analyzers. The company's first sys- tem was introduced in 1976. The new product incorporates signifi- cant features and advances which are discussed in the free literature offered by Megasystems. The ability to precisely regulate combustion timing results in consid- erable fuel savings. Further, keeping the engine balanced reduces stress and vibration and distributes the heat evenly over the engine, reduc- ing thermal stress. Preventive main- tenance can be scheduled based on actual conditions rather than time intervals. Also, Megasystems points out that early detection of faulty fuel injectors, worn piston rings, faulty exhaust valves, and cylinder liner problems result in reduced maintenance, less downtime, and overall life extension of the engine. As Megasystems outlines, this ver- satile instrument can be configured to perform as a combustion analyz- er, a peak pressure alarm unit, or a combination instrument capable of including other engine parameters for monitoring such as exhaust gas and lube oil temperatures. In addi- tion, other IBM compatible pro- grams can be run using the same instrument.

Each rudder, by itself, produces a higher lift-to-drag ratio than conventional centerline rudders. Turning diameter test results Together, they create a cascade effect that can allow 60° helm angles before rudder stall occurs. Circle 154 on Reader Service Card And because the Towmaster also re- duces rudder torque and makes more efficient use of propeller thrust, vessel operation is easier and less fatiguing. The Michigan Wheel Towmaster Nozzle/ Rudder System. It's proven its ability to increase maneuverability and overall operating efficiency in over 100 applica- tions. To learn how it can do the same for you, contact Michigan Wheel for complete facts and the name of the distributor nearest to you. 1501 Buchanan Ave. S.W. Grand Rapids, MI 49507 Phone (616) 452-6941 Telex 6877077 MIMOT UW If your vessel has a ducted propeller system, Michigan Wheel's Towmaster Nozzle/Rudder System can give you a dramatic improvement in maneuver- ability and turning effi- ciency. In fact, if your vessel presently has a fixed nozzle system, tests prove the Towmaster Nozzle/ Rudder System could reduce your turning circle by 70%. If yours is an open propeller system, you can expect an improvement of up to 60%.
