There are nine energy chains fitted to the DSB. The energy chain guides and protects
hydraulic hoses that service the component parts of the hydraulic circuits:
Two from the chassis to the slide frame.
One between the rotate cylinders.
Two from the A-Frame to the launch frame.
Four from the A-Frame routed over the stabilizer leg
The energy chains are different in size according to where they are fitted, ensure that the
correct energy chain is ordered from the RSPTL TM 5-5420-279-23P when changing them.
This principle of this maintenance procedure can be applied to any energy chain.
This procedure should be read in conjunction with unit maintenance procedure 5-096;
energy chain link replacement.
Remove the mounting nuts, bolts and washers securing both fixed ends of the energy
Insert a suitable small screwdriver under one slot on the link plates (2) and lever
The link plates (2) will unlock and the one of side plates (3) can be removed. Repeat this
process for each link in the energy chain.
Remove the separator (4), where fitted, from each link.
Remove the energy chain by sliding it off the hydraulic hoses.
It may be necessary to completely dismantle some links to allow for removal. Refer to unit
maintenance procedure 5-096 for link replacement.
When fitting a new energy chain; carry out steps 2, 3 and 4 of the removal on the new
Fit the energy chain over the hydraulic hoses.
Fit one end of the energy chain and secure it in place with nuts, bolts and washers.
Fit the separator (4), where fitted, to each link.
Fit the side plate (3) and link plate (2) to each link.
Fit the other end of the energy chain and secure it in place with nuts, bolts and washers.
Check that the energy chain works correctly by deploying the system under repair.
