An Perkins engine major overhaul is a process that involves disassembly, cleaning, inspection, repair as necessary, assembly followed by testing afterwards using Perkins factory service manual approved methods and procedures. The process generally involves honing, fitting new piston rings, new bearings, gaskets and oil seals. Perkins engines may be overhauled to different standards typically 'new limits' or 'service limits', or a combination of the two using some used parts and some new original equipment manufacturer (OEM) parts. The Perkins engine's previous operating history is maintained built is returned with zero hours since major overhaul.

A "top overhaul" on a Perkins engine is limited to the replacement of components inside the cylinder head. This can usually be done without without removing the engine , depending on its location and size.   A "major overhaul" is composed of the whole engine assembly, which requires the engine to be removed from the vehicle and transferred to an engine stand. A major overhaul therefor involves more work and costs considerably more than a top overhaul.

"New limits" are the Perkins factory service manual's fits and tolerances to which they manufacture a new engine. Probably involving the use of "standard" or approved "undersized" and "oversized" tolerance parts to ensure a good fit. Alternatively "Service limits" are the Perkins factory service manual's acceptable wear fits and tolerances. For example new-limit Perkins parts may deteriorate to these tolerances over time but still be a usable component. This may also be accomplished using "standard" and approved "undersized" and "oversized" tolerances.

Obviously, every engine overhaul is a unique process, so pricing is based on the required work. We can advise on the best and most economical course of action for your individual circumstances.
