SUBJECT: HYDRAULIC TANK BREATHER HOSE MAY BE CRIMPED INSIDE THE ROPS POST
The hydraulic tank breather hose (5P-1442 Hose) may be crimped inside the ROPS post. This can cause pressurization of the hydraulic tank.
The hydraulic tank breather assembly includes the 5P-1442 Hose (which connects to the hydraulic tank), the 207-9729 Filter As. (Breather), and the 233-5997 Hose. The 233-5997 Hose is folded onto itself before the breather assembly is inserted into the ROPS post. If the fold was inadvertently made in the 5P-1442 Hose at initial installation at the factory, the hose may be crimped enough to cause pressurization of the hydraulic tank.
Withdraw the hydraulic tank breather assembly from the ROPS post and inspect the breather assembly. Ensure that the fold is in the 233-5997 Hose rather than in the 5P-1441 Hose and that the 233-5997 Hose is not crimped. Re-insert the breather assembly in the ROPS post.
Note: Avoid applying pressure at the fold in the 233-5997 Tube in order to prevent creating a crimp or a restriction in this tube.
