REPAIR OF HYDRAULIC RAMS

1) Remove the NUTS on the ram pins on the side of the bell housing

2) Remove the hoses from the rear of the rams.

3) Remove oil from cylinders by pushing shaft in and out, aim holes in a safe

direction so when oil comes out it does no harm.

4) Place ram shell in a vice across the rear pin hole and use a pipe wrench to

remove the knurled end cap.

NOTE. In salt water some caps become frozen in place. Run a band saw along

The tube and cut off a section of the cap to the threads.

5) Pull the shaft out of the case and watch for parts, a steel tube should come out

with the shaft and a brass floating piston is inside. On the other end of the tube

should be an aluminum pressure divider with one small and one large "o" ring.

6) Clean all parts and dry with soft cloth.

7) Remove the active piston from the shaft, over a white cloth to prevent loss of small parts.

8) Sort "o" rings into groups A) The largest "o" ring and the 2 small thin o rings go in a pile with

the gold bearing supplied .B) one medium fat and one small fat ring go on the aluminum pressure

divider the other fat medium ring goes on the brass floating piston. C) the stiff quad ring goes on

the live piston. D) The soft quad ring goes around the brass scraper ring.

9) Clean , sand , and lubricate the shaft and put it upright in a vice, place the new end cap over the rod

and let it fall down, place the new stainless washer next and then use the new bearing without

’o’ rings to push the scraper ring and quad ring down the shaft.

10) Remove and place the ‘o’ rings on the gold bearing and slide it over the shaft.

11) Replace the active piston with new quad ring on the tip of the rod and tighten with ½ " wrench.

12) Slide the lubricated tube over the piston and slide it down.

13) Place the new "0" ring on the floating piston and push it into the tube, hollow side down.

14) Put the "o" rings on the pressure divider and put it into the end of the tube.

15) Slide the new outer cylinder over the whole part and pull the end cap up to the threads.

16) Hand tighten the end cap and use pipe wrench with rag to prevent damage.

17) Reinstall on boat with rear hose on rear hole fwd hose on fwd hose. Do not think left and right.

18) Fill pump tank and run up/down then refill tank.
