NOTE
All Carbureted LH685-0015, LH690-0011 & LH690-0014 were built with a longer crank-
shaft PTO than the LH775-0012 EFI. This changed in May of 2009 when the crankshaft
PTO was shortened and standardized to the same specication as the LH775-0012 EFI.
The new LH690-0017 specication uses the shorter PTO Shaft on the Carbureted models.
5. Slide the driver clutch off the PTO of the engine. (See note.)
NOTE
The driver clutch must be slid from the PTO with the mounting bolt hardware within the
clutch. The mounting bolt is too long to remove rst.
The driver clutch may contact the lower body rst before completely being free of the PTO,
however the lower body will ex enough in that area to free the clutch.
6. Remove the clutch to a clean work area for further disassembly.
