1. MOUNTING BRACKETS All Independently Mounted V Drives are supplied with 16 3 way Adjustable Mounting Brackets 2 way on the RV 10 as standard equipment ADJUSTING SCREW The brackets should face downward as shown in FIG 1 LOCKING NUT The mounting plates can be removed and reversed to fit an ni wider engine bed centers TO ADJUST BRACKETS Before installating the V Drive loosen all the nuts on the mounting brackets and position each part of the brackets so that the studs are in the center of the slots This will ensure maximum adjustability during installation and alignment Then re tighten the nuts MOUNTING HOLE Place the V Drive on the engine bed lining it up by eye to the propeller shaft coupling as closely as possible Firmly bolt the V Drive down onto the engine bed through the holes provided in the mounting plates Loosen the locking nuts on the adjusting screws SEE FIG 1 Slightly loosen the nuts on the mounting brackets just enough to be able to move the V Drive during alignment DRIVE SYSTEM ASSEMBLY All Independently Mounted V Drives are connected to the transmission by means of a floating shaft assembly which eliminates strain between the engine the V Drive and the propeller shaft By using a self aligning bearing in the front of the V Drive along with a splined shaft and flexible joint the shaft can move in and out and also angularly to take up slight engine misalignment 3 degrees ma2.
