4.Disconnect the hoses which route through the swing casting at the bulkhead fittings, as shown in image 1.2.1. Plug the open ends of the disconnected hoses to prevent dirt ingress and to aid fitting the protective sleeves.
5.Once all the hoses have been disconnected, loosen the bulkhead fitting lock nuts. This will allow any twisted hoses to find their natural route. Check the sideshift hoses and clamps for damage and replace as necessary. Take care when removing any hoses from the bulkhead clamps as they may be under tension and spring out unexpectedly. Wear appropriate eye protection.

6.Check the configuration of the machine and replace the LHS sideshift hoses as shown in the table below (image 1.3.1). Both bucket cylinder supply hoses need to be replaced. The auxiliary supply hoses and e-stick supply hoses (if installed) also need to be replaced. See image 1.3.2.

7.Additional protection needs to be added to the top sideshift hose on each side (E-stick line on LHS, Boom cyl line on RHS). Disconnect the hose from the bulkhead bracket and add 250mm of 160-2246 sleeve to the hose. Secure at each end with two 3S-2093 tie straps, as shown in image 1.3.1. Reconnect the hose loosly to the bulkhead bracket.
8.Check the alignment of the hoses. Some hoses will not spring into place and will need to be turned manually to run parallel to the other hoses.
9.With the hoses realigned parallel to each other, tighten the bulkhead lock nuts. Use a back-up spanner to hold the hose in position and prevent it twisting during tightening. Tighten the 1-1/4" locknuts to 100Nm and the 1-1/8" locknuts to 75Nm. It is important to use these torque figures as this will prevent the sideshift hoses twisted when the backhoe hoses are re-connected.
10.When all of the bulkhead fittings have been tightened, reposition the sideshift lines clamps as shown in image 1.4.2. The measurements are taken from the back of the bulkhead fitting mounting bracket and are measured along the length of the hoses.
11. Adjust the swing cylinder supply hose so that there is 500mm of hose between the last sideshift clamp and the connection with the swing cylinder (image 1.4.3). Pull the hose through the sideshift clamps as required.

ADDING PROTECTION TO HOSES THROUGH SWING CASTING
12.Check the disconnected backhoe hoses for damage along the route through the swing casting and boom foot. Pay particular attention to the area around the boom foot pins. Replace any damaged hoses.
13.Check the machine configuration and use the table below to determine what type and how much sleeving to use.

14.Pull the sleeve over the disconnected end and along the hose. Secure the sleeve to the hose coupling with the 163-8811 clamp. See images 1.6.1, 1.6.2 & 1.6.3 At the other end, secure the sleeve to the hose with 2 x 3S-2093 ties.
15.Reconnect the hoses to the bulkhead fittings. Use new o-rings for each connection.

DRESS DOUBLER PLATES
16.To further prevent the hoses rubbing, the doubler plate between the stabiliser leg and the top H-frame rail needs to be dressed.
