RE-BLOCKING PROCEDURE
Note!
Prior to re-blocking the battery, check the integrity of the battery case, lid, connector and lid seal. Renew if
damaged or showing signs of deterioration.
When re-blocking a battery ensure that the correct re-blocking kit is used. i.e. denoted by ampere-hour rating.
Warning!
Short circuit currents will exceed 2000 amps; all tools must be insulated. Care must be taken with all items
of metal in clothing and jewellery, e.g. buckles, zips, rings, watches, chains etc. Failure to pay attention to
this warning could result in serious injury or death. Battery and monoblocs are “live” throughout this
procedure.
Follow the instructions below carefully: -
a) Ensure that all parts of the re-blocking kit are present.
b) Remove and retain the four lid screws and washers.
c) Remove and retain the lid.
d) Remove and discard the nuts, washers and metal strip laminations from the rear monobloc terminals.
e) Remove and discard the nuts and washers from the front terminals and lift off the laminations.
Note!
Do not remove the front laminations from the main battery connectors.
f) Remove the expended monoblocs and replace with the new monoblocs.
g) Reconnect the front laminations using the nuts and washers provided in the re-blocking kit. Tighten the
terminal nuts using a calibrated torque wrench set to 3.9 Nm 35 pound-force inch (lbf-in).
Note!
Over tightening the terminal nuts may result in fracturing of terminal posts.
h) Connect the rear laminations across the back two terminal posts of the monoblocs using the nuts and
washers provided in the re-blocking kit. Tighten the terminal nuts using a torque wrench set to 3.9 Nm
(35 pound-force inch (lbf-in)).
i) Replace battery case lid, finger tighten all four lid screws prior to torque tightening to 1.0 Nm (9 pound-force
inch (lbf-in)).
Note!
Over tightening of the screws will cause cracking of the battery case around the screw location
holes.
