hello all first check out the picture in this url: <br /> http://www.maxrules.com/62threehp/3unit.JPG <br /><br />this is the exact picture of my 1962 johnson 3hp non shifting outboard's gearcase and water pump. i decided to give the engine a complete tune up and some restoration. the problem i am experiencing now is when i pulled out the drive shaft, the pinion gear ofcourse slipped off but now is lodged in between the back of the shift assembly behind the thrust bearing and i need to get it out to reinstall everything. the thrust bearing is still in place and i wanted to know how to remove the thrust bearing so i can reinsert the drive shaft and place the pinion gear back on the end. thanks in advanced.

I'm sure it looks easier then it is but looking at the attached drawing it looks like the bearing housing assy and prop shaft have to come out to get to the thrust and pinyon bearing.<br /><br />g'luck & c/6<br /><br />Hooty

I'm assuming you were pulling out the impeller and the driveshaft came with it...<br /><br />I've found that if I lay the gearcase on it's back with the driveshaft horizontal, I can finesse the driveshaft back into the pinion splines without tearing the gearcase down. Laying it on it's back puts the pinion about where you need it (might have to tap the housing a bit). When it falls loose in there, it doesn't have a lot of room to move, so it just needs a little gentle persuasion to get it back in place. <br /><br />Worse comes to worst, pull the rear carrier out with the propshaft and place it by hand, but try the above first....<br /><br />- Scott

yes you are correct chinewalker i did remove the impellar and the driveshaft came with it. now to see how it needed to go back together so everything will connect and turn again i removed the propellar shaft assembly already to see how to get it back together. saw the loose pinion behind the thrust bearing. i have tried to get it to manuver over where it needs to be but just not enough room to get back through to get back around the drive shaft. everything is out except the thrust bearing and the loose pinion gear. i just cant figure out how to remove the thrust bearing. it looks like maybe it should maybe turn and then be pulled out but i can't tell.

Reinsert the driveshaft in the housing. Then tap on the the end of it. This is how the thrust bearing comes out.

thanks alcan, that was too easy. you know i've inspected the inside many times and would have never guessed that the drive shaft would pop it out so simple.

Hi Jaa<br /> Tilt gear case in vice so that the pinion gear will remain in place when installed. Insert pinion gear with thrust bearing. The boss on the bearing must engage the 2 bosses in the gearcase.

alcan has it right. I just took apart my evenrude 4 and it is similar to your motor. I used a little triple 7 grease on a stick and placed this on the thrust bearing and it worked well. For those who want to try tapping on the drive shaft and not taking apart the gear assembly I don't advise this. You may get away with it but I didn't. What resulted was that I broke off the little *** on the back of the thrust bearing. I would also rotate the thrust assembly slightly to engage it with the pinion gear before tightening the bearing assembly fully. Good luck.
