q AN3-5A Bolts, Qty 6.
q AN960-10 Washer, Qty. 12

Install the Oil Cooler and Shroud
1. Attach the -43L and -43R brackets to the "back" of the
oil cooler, as shown in the photo below. The brackets are
attached to the cooler with:
AN3-5A Bolt, Qty 4
AN960-10 Washer, Qty. 12
MS20365-1032 Elastic Stop Nut, Qty. 4
Note: One washer may need to be placed between the
bracket and the oil cooler's flange as a spacer to prevent
the brackets from contacting the cooling fins.
Manufacture the Oil Cooler Brackets
1. Manufacture the three mounting brackets (SNX-P20-43L
and -R, and SNX-P20-42t. The details for these brackets
are in the back of this manual.
Modify the Oil Cooler
1. Remove a lower flange from the oil cooler to provide
clearance for the cowling.
Note: There is no left or right to the oil cooler so either
lower flange can be removed.
Above, a lower flange has
been removed to clear the
cowling. The side with the
flange removed is now the
"front' of the oil cooler.
Right, a close-up after the
flange has been removed.
If needed, an MS20365-1032 washer can be placed between
the oil cooler flange and the aluminum mounting bracket to
keep the bracket from contacting the oil cooler's fins.
