No Reverse Alpha 1

[swozzy]

Hi All,<br /><br />Ok as my other post says the gimbal issue is all sorted now. <br />Now I have another small issue that has me stumped. I have tried the search feature but it appears to not be functioning as it should??!!<br /><br />I can not get reverse gear? When the leg was off I could get both forward and reverse when moving shift lever on leg.<br /><br />Now back on boat can get forward but no matter what I have tried, including disconnecting cable from shift mechanism and moving the shift via under the leg I can not get reverse!!<br />Any clues as to what has happened here, and best I can say it all went back on as it should have with everything in the right places.<br />I'm suspecting some sort of cable issue.<br /><br />Thanks all

Re: No Reverse Alpha 1

In your Other Thread,..... You mention that the outdrive went on HARD,....... <br />That's reason enough to lead Me to believe that's Where your shifting Issue lies......<br /><br />That,+ the Corrsion Issue you mentioned,.....<br />It Could be that the Lower Shift Cable Should have been Replaced while you had it Apart.....<br /><br />Due to the Fact that it Shifted, by hand, while Off the boat,.......<br />It's Got to be a Controller/ Cable Issue.........

It's also possible the shift cable end didn't stay around the roller on the upper shift lever. The cable would push it into gear, but not be attached to it to pull it out of gear or to neutral.<br />What step in the procees of installing the drive did you have problems with, than may shed some light on your present problem. Best and easiest thing to do is pull the drive back off and check every thing then (Including the alighnment which must be dead on) and try it again. Should slide right on.

If there was some water or corrosion in the boot at some time, it sometimes turns into a mud and gets packed behind the shift slide preventing full travel into reverse

Re: No Reverse Alpha 1

Thanks for replies,<br /><br />Ok, further information now. <br />As Don suggested I pulled the drive again and rechecked everything. <br />As to the hard bit in getting leg back on, it was the last little bit and I suspect it was the 'o' rings locating into the bearing and I did have trouble a couple of times getting the large 'o' ring to stay put in the housing. In the end I just used the nuts for last 1/2" to pull it all on with very little spanner pressure to do it so did not suspect any real issue other than all the new seals etc. I was on my own and it is not easy with the weight of the leg, but got there in the end It was similar getting it off, first 1/2" or so took some convincing and then easy after that. Once again think it being the '0' rings in bearing and once they cleared it was easy. <br />Anyway, this is what I have found<br />1; The shift slide appears to not go back far enough, it hits up against the brass sleeve of the outer cable, now I'm not sure if the slide block should or would normally slide over this sleeve? Moving the shift lever on it's own, without using the slide it will travel right back and the lever at bottom of shift shaft comes up against the housing and can not go any further, this would be heaps to allow a shift into reverse if it did that with the slide block.<br /><br />2; The shift lever itself had a crack in it and when I checked further it appeared to be solid and stable on the shaft as I thought this may have created the problem with it having shifted on the shaft - not the problem..<br /><br />3; Placed a bit of leverage pressure under the shift lever and you guessed it, fell apart which I was expecting once I saw the crack running across above the rolled pin that locates it on shaft - Now I have to find one of them that could be interesting.<br /><br />4; Checked gear engagement on leg and have both forward and reverse and from all of the above checks etc. Roughly speaking the shift lever on leg looking from prop side of leg at 12.00 is forward, 10.00 is reverse. 11.00 is neutral. I'm convinced that for whatever reason the shift cable is not allowing enough pull movement to engage reverse with leg on boat and as said the slide block hits up on the brass sleeve of outer cable.<br /><br />Now I am open to your expertise as to what I need to do here. Now that I think on it, it was getting a little difficult at times to get reverse before the gimble issue and I thought it was probably a lubrication issue with the shift mechanism and cables etc, not so sure now.<br /><br />Thanks all

Re: No Reverse Alpha 1

The shift cable is probably worn out inside allowing excess movement on the inner cable. Replace it, they don't last forever.<br />Cracked shift lever? Let's put it this way. ALL the pieces of the puzzle must be in good shape for it to shift properly. You have an old drive, get the manual, follow it and fix all that is bad and it will work. Corrosion is one of your biggest problems.<br /><br />

Re: No Reverse Alpha 1

Thanks Don,<br /><br />Yes totally agree that all the pieces need to be right, but I'm still a little unsure as to why the slide does not go back far enough when moved manually by hand on the slide itself as the brass sleeve is the stop nothing else. If I move only the shift lever the travel is heaps <br />I certainly intend to replace cable, lever now the leg is off again and with this issue, but still concerned that something else is not right that I am missing. Can not see how new cable would stop this problem of enough slide travel for reverse?<br />I have a manual and it has come into very good use of late <br />Yes very old drive with corrosion but I'm not ready to put it on the scrap heap just yet, cost toooo much to get a new one <br />Will keep you posted when I manage to find the bits and time to have another go at it

Replace the cable with a new kit....Also lubricate the fasteners on the engine side of the shift bracket....I think you have a cable problem....The actual movement is really very small at the shift shaft coupler ......Does that move freely? No burrs or other interference? Barnacles?....JK

Re: No Reverse Alpha 1

the end of the cable is threaded into the housing either from the front or the rear depending on the type of cable used. this brass is crimped to the cable sheath allowing about 2 inches of plastic core to act as a guide for the shift shide.if the shift slide bottoms out in the housing this would be ample throw for reverse.a damaged roller /cracked arm/loose retaining pin/damaged shift shaft from incorrect installation/bent shoe.have you tried to shift manually just using the drive cable disconnected from the shift plate inside the boat?maybe the cable will move all the way but the control box isnt doing its job?

Re: No Reverse Alpha 1

Latest update for those of interest..<br />have ordered a new shift lever and can get so that is good news.<br />I have now also solved the lack of reverse movement.. I actually do not know how it was getting reverse before and it must have just been catching and on removing the leg it changed things ever so slightly. <br /><br />I have checked over the shift cable and come to the conclusion it is not really that old, it appears to be the newer designed one, the inner cable is in excellant condition. Anyway, this is what I found. The shift slide was actually bottoming out on the outer cable, it appears the outer cable was not adjusted correctly to gain the full travel of the slide block when cabled pulled. Adjusted cable back into housing as best it would and now have full travel as far as it will go when pulling on the shift cable. Shift block almost touches housing.<br />Now I wait on the new shift lever and see what happens once that is replaced, I am confident this puzzle is solved.
