Changing Engine Gearbox Lubricant - MacDon M1170NT5 Operator's Manual

3. Check three band clamps (A) securing the tubes in between
the two exhaust canisters.
IMPORTANT:
Do NOT change exhaust canister type, piping sizes, or
exhaust configuration. Contact your Dealer for proper
replacement parts.
4. Inspect the area around clamps (A) for breakage, cracks,
and rust-through.
IMPORTANT:
If the exhaust is leaking, tighten clamps to 12–15 Nm
(9–11 lbf·ft). If it is leaking at the band connection, replace
the seals. Contact your Dealer if the exhaust leak persists.
5. Check the tubing for dents or crushed areas.
IMPORTANT:
Dents or crushed portions of any tubing create exhaust flow
restriction and increase back pressure significantly. Even
relatively small dents will cause decreased fuel economy
and increased turbo wear. If dents are relatively large,
increased bearing and cylinder wear will occur due to
increased exhaust temperature.

Change the engine gearbox lubricant after the first 50 hours, and then at every 250 hours or annually.
