A tool needs to be fabricated to use in the removal procedure. This tool allows the engine/hydrostatic pump assembly to be lifted evenly for easier removal. Use the dimensions shown in [Figure 70-10-20] to make the engine removal tool.

Fasten securely one end of the chain to the lifting eye (Item 1) [Figure 70-10-21].

NOTE: You may need to adjust the chain which fastens to the engine a couple of times to reach the correct lifting position.

Install the chain hoist on the eyelet [Figure 70-10-22] of the removal tool.

Fasten a chain to other end of the removal tool with two bolts as shown in (Item 1) [Figure 70-10-22].
