Frequently asked questions

What does a rebuild kit contain?

Pistons
Rings
Liners (if fitted)
Main Bearings
Conrod Bearings
Thrust Washers
Full Gasket Set
Front and Rear Seals

What currency are your prices in?

All prices shown are in Australian Dollars (AUD).

What is GST and do I have to pay it?

GST (goods and services tax) is only applicable to purchases made within Australia. Overseas customers are exempt from this charge. Although, there may be taxes involved in importing the goods to your country depending on your local VAT.

What information do I need for you to be able to identify my motor?

Because there are so many different variations and applications available, we need as much information as possible:
Engine Number
Application
Month and Year*
Turbo or Naturally Aspirated
*If applicable Perkins Engine Number Guide

If you still have questions it would be best to contact our office and speak to one of the team.

What are semi finished liners?

Semi-finished liners once fitted to the cylinder block, require boring and honing to size. Finished liners are supplied pre-bored and once fitted may only require a light hone. Liners basically come in two different flavours: parallel and flanged. A description of these are below:

Parallel liner: as it says, the parallel liner is flat on all edges.

These are held in the block by an ‘interference’ or ‘press fit’. Meaning the liner is marginally bigger than the parent bore of the motor. When these are pressed into place, they may distort and conform to the shape of the parent bore. Available only in semi-finished (needs to be bored to size).

Flanged liner: yet again, as the name implies, these liners have a flange at the top.

This flange locates into a counterbore cut into the top of the parent bore. These liners can be either ‘press’ or ‘slip’ fit. Available in either; finished (pre-sized) or semi-finished (needs to be bored to size).

Why does my engine blow black smoke?

Black smoke: it indicates poor and incomplete combustion of the diesel fuel.

Block air filter or intake system
Problem with fuel injector pump or injectors
Engine timing out
Low cylinder compression (i.e. cylinders, piston rings, ring grooves)
Restricted induction system
Excessive carbon build up in combustion and exhaust spaces
Incorrect valve clearance

Why does my engine blow blue smoke?

Blue smoke: is an indication of oil being burnt.

Low cylinder compression (i.e. cylinders, piston rings, ring grooves)
Worn oil rings – sticky oil rings when cold
Worn valve guides or seals
Cylinder glazed
Incorrect grade of oil (e.g. oil too thin, and migrating past the rings)
Fuel dilution in the oil (oil thinned out with diesel)
High engine oil level

Why does my engine blow white smoke?

White smoke: occurs when raw diesel comes through the exhaust completely intact and unburned.

Faulty glow plugs
Low engine cranking speed
Problem with fuel injector pump or injectors
Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway)
Fuel air leak
Low cylinder compression (i.e. cylinders, piston rings, ring grooves)
Incorrect valve clearance
