Install the end cap
CAUTION
It is important to install the end cap in one fluid motion to-
wards the crankcase. Do not let the end cap move away
from the high-pressure cylinder while installing. If it does,
the inlet poppet can be pinched, causing damage.
1. Align the end cap so it will slide over the tie rods,
then carefully slide the end cap towards the crank-
case until the check valve makes contact with the in-
let poppet.
2. Slide the end cap towards the crankcase until the
high-pressure cylinder engages the o-ring against the
high-pressure cylinder.
3. Install one of the hex nuts, hand tight, to prevent the
end cap from springing back from the HP cylinder.
Follow Steps 1

3 to install the other two end caps in the
same way, then continue with Step 4.
4. Apply anti-seize compound to both sides of the
washers and to the tie rod threads.
5. Install washers and hex nuts hand tight.
6. Remove the temporarily installed hex nuts. Apply
anti-seize to both sides of the washers and threads,
then reinstall the nuts.
7. Use the pressure loading tool to load the tie rods
(see Loading the tie rods on Page 44).
