Fluids, capacities & service intervals

Assume nothing was done after the truck left the army. On a 710 or 712 that means about a dozen separate gear-oil fill points, a hydraulic system for the lockers as well as the brakes and clutch, and an air-cooled engine that depends on clean fins and correct valve lash. The intervals come from the factory schedule (in hours, page 214 of the manual, per Portal Hub owners), but most US owners simply change everything on purchase and then once a year. Fit new copper washers on every plug.

ITEM	SPEC / CAPACITY	INTERVAL	NOTES & PARTS
Engine oil & filter	Straight SAE 30 per the operating instructions (one veteran owner), or a 20W-50 mineral oil with ZDDP. 6.5 L listed; one owner needed 7.5 qt to the top mark after a 30-minute drain.	Owners change every 3,000 mi or yearly	Mann W940/5 (with anti-drainback valve) or W940/18. Check the level just after shutdown, because a horizontal filter can drain back and give confusing readings. Owners avoid synthetics in this engine.Mann oil filter (SAV1008M) · Swiss Army Vehicles ↗Copper seal ring, drain plug (0076030221-02) · Swiss Army Vehicles ↗
Air filter	Element in the factory housing; some trucks have the cyclone filter system confirm in manual	Check at every oil change, more often in dust	The housing, lid seal and rubber intake boot all matter on a carbureted engine that breathes dust off-road.Air filter, European repro (SAV1033) · Swiss Army Vehicles ↗Rubber boot, air intake (7122190041) · Swiss Army Vehicles ↗
Spark plugs & ignition	Gap 0.6–0.7 mm for OEM shielded plugs; 0.76 mm with civilian plugs and Pertronix. Timing 3–7 mm BTDC (owner figure)	With the valve adjustment	Military shielded plugs and wires are expensive. Many owners fit Pertronix electronic points or a full civilian conversion.Military shielded spark plugs, set of 4 (SAV6200-4) · Swiss Army Vehicles ↗Pertronix electronic ignition for the Pinzgauer (SAV2600) · Swiss Army Vehicles ↗
Valve clearance	0.2 mm intake and exhaust, set cold · firing order 1-2-4-3	Per the factory hour-based schedule confirm in manual	New rocker-cover gaskets every time, no blue RTV, and recheck carb sync afterward.Valve cover gasket, synthetic, set of 4 (7121040061AS) · Swiss Army Vehicles ↗
Cooling fan belt, fins & oil cooler	Air-cooled. Belt tension is set with adjusting washers at the split pulley	Inspect at every service	Keep every cooling tin in place and the fins clean. The SDP checklist expects to find leaves in the oil cooler. One owner reports years in 110–115°F Arizona heat without trouble when this is done. Carry a spare belt.Fan belt (7102060271) · Swiss Army Vehicles ↗Fan belt adjusting washer, 1 mm (50110608) · Swiss Army Vehicles ↗
Gearbox	≈2 L. The manual calls for MIL-L-2105 gear oil; owners use GL-4 75W-90 such as Red Line MT-90	On purchase, then per the schedule	One owner's drain-and-fill took 1.8 qt, so some oil stays inside.Magnetic drain plug, fits diffs, wheel drives and transfer case (7101324132) · Swiss Army Vehicles ↗
Transfer case	≈2.3 L, MIL-L-2105 gear oil; owners also use Red Line Heavy ShockProof	On purchase, then per the schedule	It sits inside the central tube ahead of the rear axle drive.Copper seal ring for drain and fill plugs (0076030221-02) · Swiss Army Vehicles ↗
Axle drives (differentials)	≈2 L each, 80W-90 or 85W-90 gear oil (CRC Sta-Lube SL24239 is popular)	On purchase, then per the schedule	Some owners avoid GL-5 for fear it attacks yellow metals; others say modern GL-5 synthetics such as Red Line's are safe. A 712 has three axle drives.Magnetic drain plug (7101324132) · Swiss Army Vehicles ↗
Wheel drives (portal hubs)	≈0.4 L each front, ≈0.35 L each rear; mineral 80W-90 gear oil	On purchase, then per the schedule	Fill until oil just starts to run out of the fill hole. A hub that gushes when you open it suggests a leaking diff seal, because oil is migrating along the axle. One owner's fluid summary advises against synthetics here in case a seal fails onto the brakes. Use new copper washers and don't stack an old one under the new one.Wheel drive bearings & seals repair kit (SAV4700) · Swiss Army Vehicles ↗Oil fill plug (D009080012) · Expedition Imports ↗
Steering box	The same universal gear oil as the drivetrain, per the Steyr maintenance booklet quoted by owners	Check level on purchase	ZF-Gemmer worm and roller. Seal and rebuild kits are still available.Steering gear seal (9023801) · Swiss Army Vehicles ↗
Brake, clutch & locker hydraulics	DOT 3 brake fluid in the locker/4WD circuit (owner practice); brake and clutch spec confirm in manual	Flush on purchase	There are three hydraulic systems to bleed. Replace the cracked rubber elbows under the locker reservoir before you pressure-bleed, and buy spare bleeder valves first.Rubber elbow and T-piece kit, locker, 710 (SAV5863) · Swiss Army Vehicles ↗Bleeder valve, diff-lock slave cylinder (7101285160) · Swiss Army Vehicles ↗
Drum brake adjustment	Two star adjusters per front wheel, one per rear; at least 1/8 in of lining	On purchase, then regularly	Adjust through the plug in each drum (10 mm Allen). While a drum is off, check for gear oil, which means a leaking wheel-drive seal.Brake shoes, new set of four (7102365122N) · Swiss Army Vehicles ↗
Fuel hoses & filter	7 mm hose from tank to filter (about 3 ft), 5 mm from filter to carbs (about 4 ft)	Replace old rubber on purchase	Check the filter for red flakes, a sign of a failing tank lining. Insulating the intake runners helps with hot-restart vapor lock.Fuel hose 7 mm, per foot (SAV4256) · Swiss Army Vehicles ↗Fuel hose 5 mm, per foot (SAV4257) · Swiss Army Vehicles ↗
Wheels & lug nuts	Ball-seat lug nuts only; the factory rims are lug-centric	Check torque after any wheel work	Expedition Imports warns that conical nuts can let wheels loosen or even split a rim. Balancing needs an adapter.Lug nut, fits all 710/712 with original wheels (7101533031) · Swiss Army Vehicles ↗Lug nut set of 33 for 712 6x6 (9002324BS6) · Swiss Army Vehicles ↗
