<p>An adaptor (25) is disclosed for use in mounting a transmission clutch housing (21) to a flywheel housing (11') wherein the flywheel housing defines a first bolt circle pattern (R1), and the clutch housing defines a second, substantially smaller bolt circle pattern (R2). The adaptor includes a first portion (27) and a second portion (29), the portions defining pluralities of bolt holes (37 and 43). The first portion defines a forward surface (33) and the second portion defines a rearward surface (41), both surfaces coinciding with an imaginary transverse mounting plane MP. The forward surface of the first portion engages a mounting surface (62) of the flywheel housing, while the rearward surface of the second portion engages a forward surface (54) of the clutch housing, such that the use of the adaptor (25) does not change the relative axial position of the flywheel housing and clutch housing, which would require a change in the configuration or length of the transmission input shaft (19).</p> |
