He has helped me out a bit and once he got a handle on OKAs (helped by having mine parked in his doorway (all of his doorway) he has been able to source most of the stuff listed here at good prices (including a bigger badder jack - ten-tonner of same quality for price of the six-tonner since no six-tonners were available that day!).

    Yamalube Marine grease (sticks like shyte to a blanket) high quality marine grade, I have used this grease on off road motorcycles including in competition for several years in conditions that would kill an OKA (or any other 4WD) stone dead and it is a seriously top rate product as are all other Yamalube (Yamaha) products I have used over the past 30 years or so.

  1.  Airbags Suppliers
    The model we fitted is that recommended for the Oka by the Firestone Airbag importer, The Airbag Man, their part number AB0051. This is a Firestone model 1T14C-1, which defines a family of reversible sleeve air springs. The Firestone Assembly Order Number is W01-358-5311, which defines the specific characteristics of this variant (and there are hundreds of variants). This is also the number to use for an internet search.

    You can buy these airbags from The Airbag Man, or their distributors (eg Air Springs SA , which is what we did for the first 2), or from any number of US on-line stores (which where went for the last 2 at a considerable saving (more than 50%, even after the addition of freight) or SDTruckSprings.

    Genuine Firestone pneumatic controls and gauges are also available from the same US suppliers but we found a local supplier Air Ride Suspension in Sydney who was almost as competitive, so we supported them. They can also supply the air pipe and push-fit connectors (which are very quick and effective).
  2.  Boss Air Suspension
    Boss air suspension Ph 07 5641 0174 have triple bellows air springs suitable for the very long OKA wheel travel. These compared to Firestone are tough and cheap. 
  3.  Shock Absorbers
    Shock Absorbers 
    Monroe, Magnum 60 Gas Shock Absorbers, Front and Rear, Part Number 66638 The same shock was used whether four or eight were fitted.

    3. 1/9 Monterey Road, Dandenong South Victoria, 3175 (03) 9792 4744
  2.  Gear linkages
    Gear linkages 
    Rod ends: part number BL12BD from CBC Bearings. Ensure they have M12 threads with 1.75 pitch. Note later Okas (after VIN 137) may have different rod end types and sizes.
    There are four rod ends, one on the transfer shaft and three on the gearbox shaft. The one attached above the bell housing is difficult to access but is probably not worn anyway since it only acts as an anchor point. Most pivot pin holes on linking bars were elongated due to vibration. Weld up and re-drill the correct size or pack with shim material.
    Replace all clevis pins and fit washers between the moving parts to minimise lateral movement. Movement causes noise and wear. Grease everything well.
  3.  Gear Box
    Gear Box 
    The part number for the Oka gearbox is: Spicer T5290
    Kowari Motors
    10 Trade Court,

  5.  Rear Gearbox Mounting Rubbers
    Rear Gearbox Mounting Rubbers 
    Lloyd Parsons mechanic recognised the part as being the early Landrover. Landrover part numbers are not known at this stage.
  6.  Uni Joints
    Uni Joints 

    Steering 5 332 X Spicer No. Make sure they have a grease nipple this No. joint should have.
    Note: the Spicer 5-332X has been superceeded by Spicer SPL55-4X (refer thisSpicer Parts Listing)
    Tail Shaft K5 GB10RHD
    Again these ones have grease nipples and heavy duty seals. I recommend you carry both these Uni-Joints as spares.

    Both these Uni joints are available from:
    Truckline, Wetherill Park, NSW (02) 9729 3700

    Truckline Virginia in Brisbane (make Trevor a believer) got tie rod ends from these guys. Once pushed a bit they will try hard and get what you need. Airfreighted parts at no great expense.

    The real heros though were Whitehorse trucks in Morewell Vic whom Truckline phoned to confirm part numbers etc (Whitehorse have been known to supply parts to OKA in WA first class svc so stick with these guys) some of you will already know all about this so I leave out the details.

Oka Related Questions
  1.  What is an Oka?
    A large, strong but heavy Australian designed and manufactured 4WD vehicle. It has a a forward control cabin and large carrying capacity. They are ideal for outback travel in rough and unforgiving terrain.
    It has a very reliable 4 litre diesel engine giving significant torque for off-road driving and good fuel consumption, but limited power for high speed travel.
    Weighing in at around 5 tonnes, their dimensions are approximately 2m wide, 2.5 m high and 6.5m long, depending on the configuration.
  2.  What is the typical fuel consumption?
    Between 6 and 7 km per litre is typical (14 to 16 litres per 100km, or 17 to 20 MPG) but this will vary with driving technique, terrain requirements (tyre pressures and gears/4wd selection) and load.
    Speed on the open road has the biggest impact on fuel consumption and speeds in excess of 80kph will have a significant impact.
    In off-road conditions, soft sand (particularly sand dunes) will have a negative impact and careful calculations of fuel load and range must be made taking into account unforeseen conditions. Fuel availability must also be considered. In remote locations fuel supplies can be widely spaced and occasionally unavailable.
  3.  What are the essential electrics to keep an Oka running?
    The minimum requirement is a 12 v supply to the cut off solenoid in the injector pump.
    No other electrics are essential to keep the Oka engine running although, of course, none of the dashboard displays, lights, indicators or battery charging will be operating if all you have is a 12v supply to the injector pump solenoid.
