I have a question regarding a 1991 8hp Johnson outboard J8REIA and removing/installing the shift rod before and after replacing the gear case cover. It seems to me that the only way to replace the shift rod bushing is to remove the shift rod from the gear case. The top of the shift rod is flat on both sides and although the gear case cover is slotted so that it can be slid up and over the shift rod, the bushing is not. Therefore the only way I can see to get the busing off and replaced is to slide it off the bottom of the shift rod. That being said I can see from the parts diagram and from some videos on line that there is a cam that fits onto the end of the shift rod down inside the gear case and it seems difficult to be able to re-insert the shift rod into that cam without removing the drive shaft and gears in order to align the cam and shift rod. My question is?is there a way to re-insert the shift rod into that cam without removing the drive shaft to access the cam for alignment? It seems to me there should be a way to put the shift rod and cam into a particular position prior to removing it (i.e. forward neutral or reverse) that would keep the cam in a position where the shift rod could be removed and reinstalled without having to actually have access to the cam via removing the drive shaft. If any of you out there have some insight or advice on this particular issue/repair please respond. Thanks much.

The shift rod does not have to be pulled from the shift cam in order to do any work to replace bushing or cover.------So post part # and more detail on what you have done so far.-----And removing the propshaft is not that hard to do either.----On those shift rods I install 2 o-rings to prevent leaks.--As always some will argue that it can not be done.

DuckFan, I just looked up your engine and the exploded view shows that there is an "O" ring, a shift rod bushing and also a "C" type clip (retainer ring as they call it) that goes on the lower end of the shift rod. I would assume you have to install that from the gear case side before installed the actual gears. So I don't see anyway to install it into a closed up gear case. JMHO

All:
Thank you for your replies to my issue:). I understand some of the confusion some of you who replied might have as the schematic of my gear case found on line does not accurately depict my issue. As I have discovered with his particular model and year I seem to be dealing with an ?odd Duck?. The schematic found on line would have you believe that the top of the shift rod is mostly cylindrical with one side cut away as a key way. I have found that with most replacement intact lower units that is the case as the gear case for my model motor fit many motors before and after that model year. However, it seems that 1991 might have been a transition for this model and they went with a different type of shifting mechanism that required a different shift rod. The top of my shift rod is flat on both sides which does not allow a completely cylindrical part to slide over it. This is my problem with the shift rod bushing (part No. 0324642). While the gear case cover itself is slotted to fit over the top of the shift rod, the bushing just underneath the gear case cover is not and will not slide up over the top. I need to replace the bushing as it is worn out. If you click on this link you can see a YouTube video of a guy explaining the very issue I have https://www.youtube.com/watch?v=wFTjH503IiI . In the case of the video the guy pulled the shift rod and dislodged the cam at the end of the shift rod down inside the gear case thus necessitating the need to pull the drive shaft and gears to access the cam to align it with the shift rod. I am wondering, as my earlier post stated, if there is a way to remove the shift rod and replace it without pulling the drive shaft? I was thinking that if the cam was left in a particular gear (forward, neutral, or reverse) one might be able to pull the shift rod out and replace it as long as the cam did not shift. I am wanting to know if anyone out there has ever done that and what the procedure might be. Thanks again

What is the model # of your motor.------------I see the same shift rod from 1980 to 1996 models.------

He begins by saying "I have a question regarding a 1991 8hp Johnson outboard J8REIA ........"


I don't remember any problem removing the gearcase top ( c/w shift rod) from my '84 6Hp and re-engaging the shift rod with the cam when reassembling

Dear Vic.s
When you did the work you mentioned on your motor in your post, do you recall if when you removed the shift rod if it was in a particular position (i.e. F, N, R) that made it easier to remove and reinstall? That would be helpful to know. I am thinking that is seems there is less tension on the cam when the shift rod is in the forward gear position. Any thoughts?
Thanks

Its a long time since i did this. I took the gearcase top off when replacing the drive shaft seals. (I don't remember if I also replaced the shift rod O ring.).

I don't remember what position the gear selector was in. I don't think it will make any difference.

Maybe you will find some useful info in the manuals at http://boatinfo.no/lib/library.html
