ASE A1 TEST PAPER 2025/2026 QUESTIONS WITH
SOLUTIONS MARKED A+
2. which of the following steps is the tech LEAST LIKELY to take when pressing the
✔✔18. in the figure, a thermal cleaner is being used to prepare iron and steel
components for inspection. the thermal cleaner heats the parts to:
200-300 degrees
550-700 degrees
700-900 degrees
650-800 degrees - ✔✔650-800 degrees
~this temp will cause the contaminants to oxidize. after the thermal cleaning process,
the ash is removed by shot blasting or washing the parts.
✔✔20. tech A says metal burrs on the crank flange may cause excessive wear on the
ring gear and starter drive gear teeth. tech B says metal burrs on the crank flange may
cause improper torque converter-to-transmission alignment.
A
B
Both
Neither - ✔✔Both
~Burrs on the crankshaft flange might prevent the flywheel or flexplate from seating
properly. During engine operation, this will cause the flywheel or flexplate to wobble,
damaging the flywheel and starter gear teeth (during cranking) and the transmission
torque converter bushing.
✔✔21. a bent connecting rod may cause
uneven connecting rod bearing wear
uneven main bearing wear
uneven piston pin wear
excessive cam bearing wear - ✔✔uneven connecting rod bearing war
all others are not causes of a bent connecting rod
✔✔22. tech A says the timing cover must be removed in order to replace the crank front
oil seal. tech B says the lip on the front oil seal must face toward the crank pulley or
harmonic balancer
A
B
Both
Neither - ✔✔Neither
, ~on some engines, the crank front oil seal can be replaced without removing the timing
cover. Also, lip type seals are installed with the lip of the seal facing the fluid being
sealed.
✔✔25. the LEAST likely place an RTV sealer would be used is the:
oil pan
valve cover
intake manifold
cylinder head - ✔✔cylinder head
✔✔33. when measuring main bearing bores, provided the vertical reading is not largest,
out-of-round measurements are acceptable if less than:
0.001 inch
0.010 inch
0.005 inch
0.015 inch - ✔✔0.001 inch
all others exceed spec
✔✔34. when measuring crank end play, it is LEAST LIKELY that a tech would use:
a micrometer
a pry bar
a dial indicator
feeler gauges - ✔✔a micrometer
- a pry bar may be used to bottom the crank
-a dial indicator and/or feeler gauge may be used to take other measurements
✔✔49. tech A says that when inspecting piston ring grooves for wear, you should place
a new rings in the groove and then insert a feeler gauge between the ring and the
groove. tech B says that you should simply insert a feeler gauge in the ring groove and
then compare the measurement to specification
A
B
Both
Neither - ✔✔A only
~piston ring clearance is measured by placing a new ring in the groove and then
inserting a feeler gauge between the ring and groove
