In addition to the base engine parts, we offer everything that is currently available to freshen up your engine: Marine Heat Exchangers, pumps and cooling components, Starter, Alternator (standard or high output Balmar) Serpentine Pulley Kit, Gauge Panel complete with harness and senders, Damper drive plates, Isolator Mounts, and stainless steel exhaust elbows.

The following is a list of kits and components that may be purchased. Major components shown below are supplied on an exchange basis. Your exchange components should in re-buildable condition to be accepted as a core. We can supply a copy of the core policy upon request. We welcome you sending in any core items for exchange ahead of time. This way they can be pre-inspected as an acceptable or unacceptable core. TAD will pay a one-time freight charge for our core parts being returned from within the 48 continental states. All items should be returned on the skid that was shipped to you where applicable.

Engine Rebuild Kit:
High quality aftermarket factory assembled rebuild kit contains the following: Pistons, Liners, Rings, standard main bearings, standard rod bearings (oversized bearings are available upon request.) Upper and lower gasket set, valves, guides, front and rear oil seals, oil and fuel filter. We do offer a new genuine Perkins oil pump as an additional option, however, we suggest the pump be inspected and measured for wear to determine if a replacement is required.

Cylinder Block:
The cylinder block is carefully inspected, line bore checked, magnaflux crack tested, pre-fitted with new liners ready to receive new piston assemblies.

Cylinder Head:
Complete with new valves, guides, seals fitted, magnaflux crack tested ready to be installed.

Crankshaft:
Re-ground with correct oversize bearings or standard polished. All are carefully inspected and magnaflux crack tested.

Fuel Injector Pump:
You will need to supply the DPA number located on the pump tag for accurate replacement. Please note that the injection pump rebuild pricing when supplied on an exchange basis, can exceed the quoted standard pricing by up to $400.00. This applies when the main head and rotor in your old pump require replacement. It can take up to 4 weeks to evaluate a core pump and initiate an appropriate core refund. Refunds are typically applied to the credit card used for the original purchase. A core charge can be avoided if pump is sent in for evaluation prior to the replacement pump being shipped. Core documents are supplied with each replacement pump.
