UPDATE 1-Caterpillar dealer machine sales accelerate
* Dealer machinery sales up 66 pct in three months
* Dealer engine sales up 25 pct in three months
BOSTON May 19 (Reuters) - Sales by Caterpillar Inc (CAT.N) dealers of its machinery accelerated in the three-month period ended in April, while engine sales growth slowed, the world's largest maker of heavy machinery said on Thursday.
Overall dealer sales of machines rose 66 percent in the three months ended in April, faster than the 61 percent growth for the three months ended in March. Sales growth picked up in all regions but Latin America, the company said in a filing with the U.S. Securities and Exchange Commission.
Sales of reciprocating and turbine engines, meanwhile, were up 25 percent for the three months ended in April, slower than the 45 percent growth for the three months ended in March.
Caterpillar reports dealer sales as a measure of end-market demand for its heavy equipment. The company's reported revenue reflects sales to dealers.
Wall Street expects the Peoria, Illinois-based company to report a 57 percent rise in profit for its second-quarter, which ends in June, on 30 percent sales growth, according to Thomson Reuters I/B/E/S.
