TEE TEST PROCEDURE FOR HYDRAULIC SYSTEM (CONT)
(Sheet 11 of 27)
The flow differential for each test (4 through 7)
is found by subtracting the flow rate for each
test from the base flow rate (Test 3). The per-
cent of flow loss for each test (4 through 7) is
found by dividing the flow differential for each
test by the base flow rate (Test 3) and
multiplying by 100.
Manual load valve
Open all the way.
Lift control lever
Put in RAISE position.
Make a comparison of the oil temperatures
from Tests 2 and 8. Test 2 must be 1450 to
1550F (710C to 660C) and Test 8 must be
within 100F (12.20C) of Test 2. For each
100F higher difference (Test 8 higher than
Test 2), subtract .5 gallon per pump car-
tridge from the leakage rate. For each 10F
(12.20C) lower difference, add .5 gallon per
pump cartridge to the leakage rate.
