Abstract
An apparatus for straightening a cylinder head of an internal combustion engine is provided. The apparatus includes a pair of elongate members on which the cylinder head is mounted. Tensionable members are adjustably anchored in the elongate members and pass through bores in the cylinder head. Tensioning means provided on each tensionable member enable desired forces to be selectively applied to the head to provide corrective deformation of the head. The apparatus is versatile and accommodates cylinder heads of most known makes of internal combustion engines.
Claims8
Apparatus for straightening a cylinder head of an internal combustion engine, said apparatus comprising:
- a pair of elongate members adjustably spaced from each other and on which said head is mounted in use, each elongate member having a slot extending longitudinally along its upper side;
- at least two tensionable members, each having (i) a retaining member at one end thereof which is captively received in the slot of an associated elongate member yet is adjustable in position along said slot, (ii) a shank portion which in use is located in a respective bore through the head, and (iii) adjustable tensioning means at the other end thereof for applying a force to said head;
- whereby said head can be straightened by selected application of forces thereto by said tensionable members at predetermined locations.
Apparatus for straightening a cylinder head of an internal combustion engine, said apparatus comprising:
- a pair of elongate members adjustably spaced from each other and on which said head is mounted in use at 90.degree. to its normal orientation, each elongate member having a slot extending longitudinally along its upper side;
- a pair of cross members adapted to be placed transversely across the cylinder head in use, each cross member having clamping means for securing it to the cylinder head;
- at least two pairs of tensionable members, each having (i) a retaining member at one end thereof which is captively received in the slot of an associated elongate member yet is adjustable in position along said slot, (ii) a shank portion which in use passes through a respective bore in a cross member, and (iii) adjustable tensioning means at the other end thereof for applying a force to an associated one of the cross members;
- whereby said head can be straightened by selected application of forces to the cross members by said tensionable members.
