Democrats working on a 1984 platform found that papering over differences may not be easy. Page B9. WASHINGTON, April 9 - Vice President Bush, wading into the 1984 political campaign, went before a Jewish organization today and harshly criticized the three candidates for the Democratic Presidential nomination as failing to issue strenuous condemnations of anti-Semitism. ''Whom the Democrats pick is their business,'' said Mr. Bush, speaking before the annual policy conference of the American Israel Public Affairs Committee, a lobbying group. ''But some matters transcend party and concern the basic traditions of our republic.''

Citing the ''time-consuming distraction'' of an investigation being conducted by the Securities and Exchange Commission, Peter N. Brant submitted his resignation yesterday to Kidder, Peabody & Company. Mr. Brant, a 31-year-old vice president said to be the brokerage firm's top salesman, has been a key figure in the S.E.C.'s investigation into the possible improper use of market- sensitive information before its publication in The Wall Street Journal's ''Heard on the Street'' column. Two weeks ago, The Journal reported that it had dismissed R. Foster Winans, one of the column's two chief authors. The newspaper said he had admitted to the S.E.C. that he periodically made information available to outsiders before publication.

Renovation plans for Shea Stadium, including the installation of artificial turf, additional stands in center field and luxury boxes, will be announced today by Mayor Koch. The Mayor did not give specifics in advance of his official announcement, but two nongovernmental sources close to the negotiations described the details of the remodeling, which both said would cost $45 million to $50 million. A city official, however, said that the projected cost was less than the $43 million the city offered last fall to make improvements in an unsuccessful attempt to deter the Jets from moving to New Jersey.

Federal authorities charged 31 men yesterday with operating an organized- crime ring that has brought $1.65 billion worth of heroin into the United States since 1979. ''It is the most significant case involving heroin trafficking by traditional organized crime that has ever been developed by the Government,'' Attorney General William French Smith said at a news conference at 26 Federal Plaza in Lower Manhattan. ''We estimate that the ring has imported at least 330 pounds of heroin a year for the past five years,'' Mr. Smith said. A key part of the heroin ring was described as ''the Catalano faction of the Bonanno family of La Cosa Nostra'' in New York City. The leader of the faction was identified as 43-year-old Salvatore Catalano of Queens, who was accused of being a major heroin distributor.

The Soviet Olympic Committee charged today that an anti-Soviet campaign was taking shape for the Games in Los Angeles this summer and asked for an emergency session of the International Olympic Committee to look into security and to demand American adherence to the Olympic charter. In a statement issued by Tass, the official Soviet press agency, the Soviet Olympic Committee did not directly threaten a boycott of the Games by its athletes. But it noted that the time was drawing ever nearer for the Olympic committees of the various nations to make a decision on participation. The deadline for registering is June 2.
