Specifications

About the rings

The Hastings B16 Rings 81.5mm includes the top compression ring, second ring and oil control ring for all four pistons. Hastings has made piston rings since 1915 and makes nothing else, supplying engine makers as well as rebuilders.

Choosing the size

Ring size must match the bore. The Hastings B16 Rings 81.5mm is the 0.50mm oversize size for a 81.50mm bore, so measure the bores after honing or boring and match the rings to the finished size. Standard and oversize sets are available for these engines.

Fitting

Check each ring gap in its own bore, square to the bore, and file to the engine builder’s figure if needed. Fit the oil ring first, then the second and top rings with any marks facing up, and stagger the gaps. A correct bore finish matters for the Hastings B16 Rings 81.5mm to bed in and seal well.

Rings are normally renewed whenever the pistons come out, along with new bearings and gaskets. Clean the ring grooves fully before fitting new rings, and oil the bores and rings well on assembly.
