Volvo A45J hydraulic oil change procedure

Volvo A45J Hydraulic Oil Change Procedure
Goal: Replace contaminated hydraulic fluid and filters.
Prepare Machine: Park on level ground, lower attachments, and engage the parking brake.
Warm Oil: Run the engine to circulate oil until it reaches approx. 50°C (120°F), then shut it off.
Drain Tank: Place a drain pan under the hydraulic tank, remove the drain plug, and let the oil drain completely.
Replace Filters: Remove and replace the hydraulic return filter and suction strainer with new ones.
Refill System: Reinstall the drain plug with a new seal. Refill the tank with approved Volvo hydraulic fluid to the “FULL” mark.
Purge Air: Start the engine and cycle all hydraulic functions (steering, hoist) slowly to remove air from the lines.
Final Check: Turn the engine off and re-check the sight glass. Top off the fluid if necessary.

Goal: Obtain an accurate reading of the transmission fluid level.
Position Unit: Ensure the hauler is on level ground with the parking brake firmly engaged.
Warm Up: Start the engine and let it reach operating temperature (idle).
Cycle Gears: With the brake applied, shift slowly through all forward and reverse ranges, then return to Neutral.
Check Level (Engine Running): Leave the engine idling in Neutral. Locate the dipstick, pull it out, wipe clean, and reinsert fully.
Read Dipstick: Remove the dipstick again and check the fluid level. It should be within the cross-hatched operating range.
Add Fluid (If Low): Add approved transmission fluid in small increments through the dipstick tube.
Re-check: Wait one minute for the fluid to settle, then repeat the reading process to verify the correct level.

Goal: Separate the final drive hub assembly from the axle spindle.

Safety First: Securely support the machine on heavy-duty jack stands and remove the wheel/tire assembly.
Drain Oil: Remove the drain plug from the final drive housing and drain the oil completely.
Remove Flange: Unlock and remove the drive flange nut and bolt. Use a puller to remove the drive flange.
Unbolt Housing: Remove the bolts that secure the final drive housing to the axle housing.
Support Weight: Position a wheel dolly or transmission jack securely under the final drive assembly.
Separate Unit: Use pry bars evenly on both sides to carefully separate the hub from the spindle.
Remove Assembly: Once free, slide the final drive unit off the spindle and lower it away from the machine.
