New Spur Gear, Shrink-Fitting

Note

Check the temperature with the Digital Thermometer -

VAS6519- when heating up the new spur gear.

When the temperature reaches 200 ℃ (392 °F), there are

about four seconds to position the spur gear on the crankshaft.

A higher temperature increases the amount of time available

for positioning (220 ℃ (428 °F) = approximately six seconds).

Make sure the crankshaft journal is clean.

Caution

Do not exceed the maximum temperature of 240 ºC (464 °F).

Otherwise the spur gear will discolor and possibly become dis‐

torted.

– Lay the entire surface of the new spur gear on a commercially

available hot plate and heat it to at least 200 ºC (392 °F), max‐

imum 240 ºC (464 °F). The lettering faces upward.

WARNING

There is a risk of burns. Wear suitable safety gloves during the

rest of the procedure.

– After the temperature is reached, remove the spur gear from

the pliers as shown.

Note

Make sure the splines on the spur gear are not damaged.
