Great tip on starting your Wisconsin Engine under a high load
Recently, some of our customers have told us that Wisconsin engines with high accessory loads may benefit from a new starting procedure, one different than what is specified in the operators’ manual. The high shock loads that inhibit easy starting are due to hydraulics, fans, etc., that are not disengaged before starting. They prevent the engine from easily getting up to speed. This Tech Tip will remind some mechanics of the compression release process in older, hand-start diesels.
To enable the engine to get to the optimum speed:
- Make sure the throttle is fully shut and the choke is off (plate open).
- Engage the starter, spin the engine for 3 seconds to allow engine speed to increase, then pull back in when the engine fires. The choke plate should not have to be closed for more than several seconds, even in cold climates. Do not use ether.
- If the engine stalls, repeat the procedure, this time pushing the choke in more slowly after the engine fires.
- Choking may not be necessary for hot restarts. If required, use only a quick pull of the choke after the engine is spinning, with an immediate return to the open position.
