DS900X Engine Oil & Secondary Oil Filter Change

The DS900X uses forced pressure and splash lubrication Engine manual p. 7. The oil drains from two points, the oil bottom case and the oil tray Engine manual p. 27, and the engine has a secondary oil filter.

Service interval

The manuals give different intervals for changing the oil and the secondary filter. We cannot verify which is correct.

• English owner's manual maintenance plan Owner's manual p. 88: oil replaced at 1,000, 10,000, 20,000 and 30,000 km and inspected at 5,000, 15,000, 25,000 and 35,000 km. The lubrication element is replaced at 1,000, 10,000, 20,000 and 30,000 km. The page says time or mileage applies, whichever comes first, but the table gives no time for the oil.
• Engine workshop manual maintenance table Engine manual p. 20: oil replaced in every column: 1,000 km / 1 month, 5,000 km / 6 months, 10,000 km / 12 months, 15,000 km / 18 months, 20,000 km / 24 months, 25,000 km / 30 months and 30,000 km / 36 months. The secondary oil filter is replaced at every column from 1,000 km / 1 month to 30,000 km / 36 months.
• Swedish owner's manual Swedish owner's manual p. 107: first service at 1,000 km or 3 months, then services at 10,000, 20,000, 30,000 and 40,000 km or every 12 months, whichever comes first.
• Hungarian service schedule Hungarian service schedule p. 1: engine oil and oil filter replaced at every column it prints: 1,000, 8,000, 16,000, 20,000, 24,000, 36,000 and 42,000 km. This document may be a machine translation.

Specifications at a glance

Where the manuals give different values, each value is listed with its sources and the row is marked Sources differ. We cannot verify which value is correct.

The owner's manual also prints a temperature chart for oil viscosity and a note to use 5W-40 or 0W-40 in winter and 10W-40 or 20W-50 in summer Owner's manual p. 75.

The DS900X has a wet multi-plate clutch Engine manual p. 7. Buy oil that states JASO MA2 and an API grade from the table above on the bottle, and is not marked as energy saving.

What you need

• 3.0 L of fresh oil if you replace the secondary filter. Without the filter change the manuals give 2.7 L or 2.8 L. A 4 L jug is enough.
• New secondary oil filter. The owner's manual asks for original VOGE parts Owner's manual p. 76.
• Two new sealing washers for the drain plugs, and two new drain bolts if you follow the owner's manual (see the table above).
• Sockets that fit both drain plugs. The manuals do not give the sizes.
• Cap-shaped wrench for the secondary oil filter, the Voge special tool Engine manual p. 19
• Torque wrench that covers the values in the table
• Drain pan (4 L+ capacity)
• Funnel, rags, gloves
• Container for the used oil

Procedure

The steps below follow the engine workshop manual p. 26-28 and the owner's manual p. 72-76, with the differences in the other manuals noted.

1. Warm the engine

The manuals say to change the oil when the engine is warm, so the old oil drains fully. Ride for 5-10 minutes, or run the engine on the centre stand until the cooling fan starts.

2. Park level, prepare

Park on the centre stand (technique guide) on level ground. Stop the engine. Place the drain pan under the engine.

Remove the oil dipstick.

3. Drain: bottom case first

Locate the bottom case drain bolt (M16). The owner's manual places it in the middle of the engine bottom. Remove the bolt and its copper sealing washer and let the oil drain.

Wait until the oil has stopped flowing.

4. Drain: oil tray

When the oil has stopped flowing from the bottom case, remove the oil tray drain bolt (M10, on the oil collection tray) and let the remaining oil drain.

If you skip this plug, old oil stays in the tray.

5. Replace the secondary oil filter

The maintenance tables replace the filter with the oil or more often (see Service interval above). While the oil is draining:

• The chassis workshop manual p. 11, places the oil filter at the right rear side of the engine. The Swedish owner's manual p. 91, places it at the front of the engine. We cannot verify which is correct. Put the drain pan under the filter.
• Remove the filter with the cap-shaped wrench and let the oil in it drain.
• Wipe the filter seat on the engine clean.
• Coat the threaded part and the o-ring of the new filter with oil.
• Fit the new filter and tighten it with the cap-shaped wrench and a torque wrench to 11 N·m.

The engine workshop manual also says to confirm that the filter tube joint is tight. Its torque differs between the manuals (35 N·m or 28 N·m, see the table).

A "3/4 turn by hand after o-ring contact" rule of thumb is common for cartridge filters. This site has not found it in the Voge manuals, so use a torque wrench.

6. Reinstall drain plugs

Fit new sealing washers on both drain plugs (and new bolts if you follow the owner's manual). Reinstall in this order:

• Oil tray drain plug: 10 N·m (the chassis workshop manual gives 8 N·m for the "internal" drain bolt, see the table).
• Bottom case drain plug: 25 N·m.

Use a torque wrench. Do not over-tighten.

7. Refill

Pour fresh oil into the filler hole using a funnel:

• 3.0 L if you replaced the secondary filter
• 2.7 L (engine and chassis workshop manuals) or 2.8 L (owner's manual) if you didn't. Fill to 2.7 L and use the dipstick check below.

Pour slowly.

8. Check oil level

The manuals give this procedure:

1. Put the bike on the centre stand on level ground (technique guide).
2. Start the engine and idle until the cooling fan starts working.
3. Continue idling for 1 more minute.
4. Stop the engine.
5. Wait 1 minute for the oil to flow back.
6. Clean the area around the filler port.
7. Pull the dipstick, wipe it with industrial tissue, insert it and turn it in by 1 full turn, then remove it and read the level.

The level must be between the upper and lower marks. If it is below the lower mark, add oil and check again. If it is above the upper mark, remove some oil and check again.

The chassis workshop manual p. 10, also says: when the oil is filled, idle the engine for 30 seconds and check the level once again.

The manuals give different locations for the dipstick: on the right engine cover in the owner's manual p. 72, at the left rear of the engine in the chassis workshop manual p. 10, and on the left side in the Swedish owner's manual p. 88.

9. Verify no leaks

Check the bottom case drain plug, the oil tray drain plug and the secondary filter for leaks.

If anything leaks, fix it before riding.

10. Reset the service indicator

The maintenance indicator does not clear itself. See the DS900X service indicator reset guide.

11. Disposal

Dispose of the old oil and the old filter in an environmentally friendly way. Pour the oil into a sealable container (the empty oil jug works) and take it to a used-oil collection point.

Common pitfalls

• Wrong oil grade. The engine workshop manual requires JASO MA2 and no energy-saving oil. The API grade differs between the manuals (see the table).
• Skipping the oil tray drain. The tray plug is the smaller one (M10) and easy to overlook. Find both plugs before you start.
• Reusing sealing washers. The owner's manual warns that reusing the old drain bolt and seal ring can cause oil leaks.
• Over-tightening drain plugs. Use a torque wrench and the values in the table.
• Reading the dipstick wrong. Reading straight after the engine stops gives a low reading, because oil is still flowing back. The manual waits a minute first and turns the dipstick in by 1 turn.
• Forgetting the indicator reset. See step 10.

Use only the DS900X figures on this page. Do not carry values over from other models or engines.
