We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

  • Volvo 270T Help needed to bleed the tilt cylinder.

    Can somebody please help me with the correct procedure to bleed the hydraulic system?I’m running a 270T with 302 Ford in a 20’ Cobra Ski boat. Recently I noticed a clunk noise when going from a trailing throttle to moderate or full power again. Upon investigation it seems the leg is moving back off the trim push rod when I back off (about 1 inch). It than slams back against the rod when the power is reapplied. This led me to believe that the trim or tilt mechanism required bleeding, after attempting this via the bleed nipple at the top of the tilt cylinder all I managed to do was make it worse. I now have about 6 inches of free play. Please, please, pleaseeeeee help!

          Goughs Bay, In-laws have a house there. Nice to see some better water levels this year! And more good rains last week or so will help a lot. Last year we were pretty much off the water at Goughs by Easter as the good ski inlets around the river mouths were just getting to shallow. This year looks like it will be a good one with good levels right through the season. :-)

            I recently sold my runabout, it had a 270 (not trim) and 302w. What you got there is rare around here, I searched for a 270T for three years without luck. Tony at Eildon outboards does carry some secondhand parts though & he's a good guy - won't rip you off.Is your ram leaking?Yep, it's over 50% now, that about 15% better than this time last year. Should be a good season - and the trout are biting!

              Yep, rare but very happy. Boat has been on the lake for over 20 years and the whole kit is in 'like new' condition. No leaks at all from the cylinder. I'm confident its just due to be bled but we just couldn't get it right......... I'm assuming there is a procedure to follow, but until I know the procedure I'm a bit stuck. I'm sure when day breaks in Nth America I'll get some help.I know Tony and yes he has a good reputation. I will take it to him if I have to, but would prefer to fix it myself if I can.

                Fill with hydraulic oil (see ¬ďTechnical Data¬Ē) and checkthe function of the hydraulic pump and for leakage. Thesystem is vented automatically by raising and loweringthe drive several times.Drive tends to float up during dethrottling.11 Leakage in safety release valve12 Leakage in safety valve13 Leakage past the piston sealing in the lift cylinder17 Leakage in the double valve or its O-rings20 Leakage past the piston rod sealing in the lift cylinderThis comes from Volvo #7726380-4Workshop manual AQ270TLooks like you might need a little more than bleeding, might want to order the manual.Good Luck muc

                  Well Aldo, if you was refering to me, he's in trouble. I have never even seen a 270T.

                    Ok so I'll take from that, there is not a 'bleed procedure' as such. Thanks to all who offered help with my problem. Seems I'll be rebuilding pumps and rams this weekend!!!!!

                      Oh well, doesn't hurt to ask.Paulie, Don pretty well lives and breaths pentas'. If he don't know, nobody will. Give Tony a call, I have seen 'T's up on the lake, I'm confident (but not sure) he has worked on them and he will give info over the phone.Good luck.Aldo

                        You don't bleed hydraulic cylinders. There's no need, ever. When oil goes in the "rod" end, the "base" end oil goes back to the reservoir. If there's air, it goes back to the reservoir too, and floats out in the reservoir which is vented to atmosphere.If you ever get air in your cylinders taking them apart or whatnot, just run them all the way in and out once you get everything back together- air gone.

                          Thanks for the info hystat, based on that I should be ok after the pump and rams are rebuilt. I did them around 10 years ago, seems like a long time but with the boat only getting wet for a couple of months each summer its not all that long in hours running. Maybe just a case of fluid leaking back past the seals in the trim ram. I'll start by rebuilding that and see where I get to from there.Thanks again to all for your help.

                            Does anybody have a link to an exploded view of the upper unit including the tilt and trim rams and pump? Or a parts list? Thanks
