STEERING AND DRIVELINE PREVENTIVE MAINTENANCE
– 240 – Y53-6033
Regional Haul (R05/10)
If these checks do not reveal the problem, or if you correct
them and still have a steering problem, take your truck to
an authorized Peterbilt Dealer for evaluation.
Fluid Level and Refill
Have the power steering fluid and filters changed at an
Authorized Service Center.
• Check and completely change the fluid level accord-
ing to Table 1, “Recommended Maintenance Inter-
vals,” Page 150. Use the following procedure:
NOTE: Before removing reservoir cover, wipe
outside of cover so that no dirt can fall into the
reservoir.
The power steering fluid reservoir is attached to an under-
hood bracket on the LH side of the engine.
• Maximum / Minimum level is marked on the reservoir.
These same levels are also marked by lines on the
dipstick in the reservoir.
• There are two ways to check whether the power
steering fluid is at its proper level. Both checks are
with the engine NOT running.
1. If you check the fluid with the engine and steering sys-
tem COLD the fluid level should be at/or above the
Minimum indicator level and should generally not
exceed the middle point between Maximum and Mini-
mum level indicators.
