RA Power Solutions provides insitu (onsite) line boring services for large marine engines, diesel engines, compressors, and gearboxes. If the equipment is massive and requires precise alignment, we bring the tools and skills to fix it right where it’s installed—no dismantling, no shipping hassles.

When serious damage affects the main journal housings on an engine block, we permanently fix it by installing a sleeve and line-boring it back to perfect alignment. Precision is the whole point — and we don’t compromise.

Services provided by RA Power Solutions include:

• Onsite correction of main journal housings using line boring, restoring alignment exactly to manufacturer specifications.
• Oversizing of damaged main journal housings when required — usually one or two. After this, special bearings are installed for a perfect fit.
• Onsite metal stitching of cracked castings, along with sleeve installation to reinforce strength.
• Complete rebuilding of heavily damaged main journal bores using onsite line boring machinery.
• Correction/repair of dowel pin holes, main journal caps, and cap bolt threads—everything back to proper alignment and torque specs.
• RA Power Solutions doesn’t just repair engine blocks—we extend their life, boost performance, and save clients massive downtime and replacement costs.

RA Power Solutions delivers onsite repair and reconditioning services for marine engines and heavy industrial equipment, including crankshaft grinding, in-situ line boring, engine block restoration, metal stitching of damaged engine blocks, and alignment correction—we show up anywhere in the world, fix the problem at your site, eliminate dismantling and downtime, and get your machinery back to peak performance faster and more cost-effectively than replacement.
