Reassembly IMPORTANT: Later model Alpha One drive units use a trim cylinder that is 3/4 in. (19mm) longer, to achieve 6 additional tilt. Earlier model R, MR and Alpha One, as well as Bravo drive units, use the shorter trim cylinder. DO NOT attempt to substitute trim cylinders or damage to drive unit and/or transom assembly could result.
2. Install small o-rings (c) and continuity spring (d) into end cap (e). 3. Install rod scraper (f), plain washer (g) and retaining ring (h) into end cap (e). 4. Install large o-ring (i) onto outside diameter of end cap (e). 5. Install end cap (e) onto piston rod.
Trim cylinders can be identified by a casting number on inboard side of trim cylinder. Shorter Cylinder: 98704--1
98703,

! CAUTION Ensure work area and all components are clean before reassembling trim cylinders. Power Trim components can become damaged if dirt gets into system.
NOTE: Before reassembly, lubricate all internal parts with Quicksilver Power Trim and Steering Fluid or SAE 10W-30 or 10W-40 Motor Oil.

6. Install large O-ring (j) on shock piston (k). 7. Install check ball (l), check ball eyelet (m), spring (n) and spring pin (o) into shock piston.
10. Apply oil to parts. Install o-ring (w) onto floating piston (x) and insert floating piston into cylinder (y).
8. Apply Loctite 27131 or Type “A” to threads of bolt being used in the following step. 9. Install shock piston, three check balls (q), spring guide washer (r), spring (s), spring guide (t), spring guide washer (u) and bolt (v) onto piston rod. Torque to 15-20 lb. ft. (20-27 N·m).

12. Position trim cylinder rear connecting ends as shown.
! CAUTION Ensure work area and all components are clean before reassembling trim cylinders. Power Trim components can become damaged if dirt gets into system.
NOTE: Before reassembly, lubricate all internal parts with Quicksilver Power Trim and Steering Fluid or SAE 10W-30 or 10W-40 motor oil.
! CAUTION DO NOT clamp center section of trim cylinder during reassembly. If clamping of cylinder is necessary, clamp cylinder on front mounting flange.
! CAUTION Use only 2-4-C Marine Lubricant on end cap threads. Other substances may act as an insulator and cause poor electrical continuity between cap and cylinder which could cause a corrosion problem. 11. Apply 2-4-C Marine Lubricant to end cap threads and install piston rod assembly into cylinder. Tighten end cap securely using a spanner wrench.

Installation ! CAUTION Use water and soap solution to aid in installing rubber bushings. The use of petroleum based product (oil and grease) can deteriorate rubber. 1. Install trim cylinder forward mounting hardware as shown. 2. Coat anchor pin threads with 2-4-C Marine Lubricant (to prevent threads from galling). 22060
3. Hand thread locknuts onto pin. DO NOT tighten at this time.
