This motor was assembled over a twelve-month period (c.2007) from various components the B-24 Liberator restoration group had stored. It was the first exercise to allow the group to understand the configuration of these motors as well as get experience in general methods of repair. This motor was nicknamed 'The Bitza', referring to how it came to be. While it may not be of a high standard, it is capable of being run on the test rig for visitors.

This motor was purchased from New Zealand (2bx c2008). This motor came with a log book showing it had operated for a total of 1577 hours and was removed from service because it was approaching the deadline of 1600 hours which required it to be overhauled or replaced. No starter motor came with it, so the B-24 Liberator restoration group reconditioned one from stock, After a thorough health check, and basic adjustments, this engine was first run in May 2009 and has been cycled through regular engine run schedule ever since.The Pratt & Whitney R 1830 is a double row 14 cylinder air cooled radial engine with a capacity of 1830 cubic inches, (30 litres), developing some 1200 horsepower at a maximum 2700 rpm.Engine Number 490571

This engine was used by RAAF 21 Squadron personnel to manufacture and fit up exhaust systems and had been left standing for a long time without any preservation treatment. Much effort was put in to free up the motor and after it had been made to turn, checks by borescope showed some fretting had occurred in the cylinder bores. This was deemed not serious enough to warrant a strip down. It did need repairs to the ignition looms and various other adjustments but first started on the 16 July 2009. Various fuel problems were evident and repairs have been done and it now runs very well. All parts used in getting this motor to run successfully came from the fund's own stock or parts included in other purchases.

Early experience resulted in this motor being partially dismantled to investigate load knocking when turned over on the starter motor. Subsequently it was discovered that the "noise" was normal, a unique aspect of the 1830 engine. The engine was then re-assembled to an operational state using parts from stock.The Pratt & Whitney R 1830 is a double row 14 cylinder air cooled radial engine with a capacity of 1830 cubic inches, (30 litres), developing some 1200 horsepower at a maximum 2700 rpm.Engine Number 361184
