Subject: SEAL PULLER #377067 - 18, 35 and 40 H.P. ENGINES
Factory figures 1 through 3: seal puller and seal removal preparation
This tool was originally designed to remove the single lip top crankcase seal formerly used without having to disassemble the powerhead, (Fig. 1). Although it works easily with the single lip seal, removal of the double lip seal currently used is more difficult. The difficulty arises in trying to force the puller past the upper rubber lip in order to engage the threads of the puller with the metal case of the seal.
To eliminate this problem, use a sharp, thin bladed knife to cut away the upper lip as follows: 1. Push the point of the blade through the lip next to the seal case and cut completely around the circumference, (Fig. 2). Remove loose piece of the lip. 2. Place the puller over the crankshaft in the conventional manner and screw it into the seal until it stops, (Fig. 3). 3. Turn the center screw of the puller until the seal is withdrawn from the crankcase, (Figures 4 and 5), see over.
Price of puller #377067 is $4.50 net, F.O.B. Galesburg, Illinois.
