MAINTENANCE AND SERVICING
3. Check the three band clamps (A) securing the tubes in
between the two exhaust canisters.
IMPORTANT:
Do NOT change exhaust canister type, piping
sizes, or exhaust con fi guration. See your Dealer
for proper replacement parts.
4. Inspect the area around clamps (A) for breakage,
cracks, and rust-through.
IMPORTANT:
If exhaust is leaking, tighten clamps to 12–15 N · m
(9–11 ft · lbf). If leaking at band connection,
replace seals. Refer to your Dealer if exhaust
leak persists.
5. Check tubing for dents or crushed areas. Dents or
crushed portions of any tubing create exhaust fl ow
restriction and increase back pressure signi fi cantly.
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.

5.9.6 Changing Engine Gearbox Lubricant
Change engine gearbox lubricant after the fi rst 50 hours, and then at 250 hours as follows:
NOTE:
The engine should be warm when changing the lubricant.
1. Park windrower on a level surface.
2. Stop the engine and remove the key.
3. Place a 4 liters (1 US gallon) drain pan under the gearbox.
4. Remove drain plug (B) and allow lubricant to
completely fi nish draining.
5. Install drain plug (B) and remove check plug (A).
6. Add lubricant until oil level reaches check plug (A).
For lubricant speci fi cations, refer to 5.1.3 Lubricants,
Fluids, and System Capacities, page 236 .
7. Replace check plug (A).
8. Operate the engine at low idle and check for leaks at
the check plug and drain plug.
