No, they didn't. The Czar was overthrown, actually forced to abdicate, by the workers, soldiers and peasants who revolted in Petrograd (St. Petersburg) in 1917. The February Revolution took Lenin, who was in Switzerland at the time, and the Bolsheviks completely by surprise. The Czar's ministers and military leaders realized the Czar no longer had any power to stop the demonstrations and strikes in Petrograd and convinced him to abdicate in March 1917.
Czar Nicholas II was first taken by the forces of the Russian Provisional Government after he was forced to abdicate his throne. Later after the Bolshevik Revolution, he was taken into Bolshevik custody. In July 1918, the Czar and all his family were murdered by the Bolsheviks.
It should be remembered that the Bolsheviks never overthrew the Czar. He was already out of power by the time the Bolsheviks took over.
The Mensheviks and Bolsheviks were the main factions in the soviet councils and the main factions involved in the March 1917 overthrow of the czar. The Mensheviks established the Provisional Government which the Bolsheviks wrested power from in the November Revolution.
