Prop Shaft Stuck in lower unit with bearing!!!

[Eluder1]

New to S&F have a Checkmate Eluder 1984 200 HP Mercury.
I started to removed everthing due to seal leak but the damm prop shaft won't release! Ball Bearing stayed in lower unit! I followed all procedures in Merc Book---NO LUCK! Still trying to dislodge shift cam as outlined-I can not even reinsert the shift shaft-yes it is in neutral-I see the oval -only half of it -lenght wise if I look down through shift shaft tube-I can move it a little by turning prop shaft!
What am I doing wrong or need to do??? Thanks, Eluder1.

Don't keep posting the same question. When the guys that know come along you will get an answer. Multiple threads on the same subject are a waste and make it hard to follow when you do get the conversating going.

Computer froze when I went to post, so I reposted thinking it did not send--Sorry--Damm Computers!!!

you lay it flat on the starboard side of the case and tap the case while pulling on the propshaft ????

[Eluder1]

Yes I did all procedures outlined in Service Manual---I found the problem the bearing & reverse gear thrust ring is keeping it from moving "a little corrision found". Note: Bearing Carrier Assembly "Carrier Only " came out without the Bearing and gear.
Can I put the prop back on and heat bottom of case and use prop to pry shaft out?
Thanks! Eluder1..

hmm those two items have clearence between the shaft and the thrust ring and they could be welded to the shaft and still slide out if its not bound by the cam as the land that it spins on is in front of them

[TEXAS20225]

what i built this ( because sometime really old lower units like the one your working on that dont get opened up fro a few years do stick) steel nut same thread as propshaft nut welded to a slide hammer rod a 5 pounder will do thread it on the shaft and let er rip it will pull it out and destroy the case if the cam is crossways

[Eluder1]

Talked to two Merc Mechanics and they said put LU so prop shaft is facing down heat area and pull on prop shaft while taping around case, the other put the prop on, place wood block between prop and housing then tighten nut.
NOW you make me think how do I know for positive that I dislodged the Cam???-I did the procedure as per merc book and would hate to destroy the case! Thanks!!!

id would say the two mercury mechanics have no tools if they told you to put the prop back on and heat the case up to dislodge corrosion??? nearly every marine dealer ive ever seen has the proper tools for that and the prop and heat is not it. i built my puller but merc has them just like it only twice as much money good luck :cheers:

What type of puller and what are you attaching to to pull what??? Carrier is out of lower unit bearing and reverse gear with prop shaft remain. I know you are trying to help but your answer is not what I asked---like they say a picture is worth a thousand words. Can you send a picture of this puller and explain what it is removing because I have alot of diffrent Merc tools for the lower unit for overhauling. Thanks again!!!!! Will check email tomorrow...Eluder1.

The cam has to be hanging up can't see the rev gear washer getting stuck in the case. But there is a first time for everything.

Dave some times they do if its not been apart for a few years and run in saltwater. E1 let me start by saying i really dont have any idea how many lower units ive rebuilt 100's so im not making stories up !!! are you trying to remove the propshaft ? then what else would you attach it to ? the prop shaft threads, do you know what a slide hammer is ? thats why i said nut same size as propshaft threads was welded on the end of the slide hammer shaft! the nut the same size as the prop shaft threads screws it on the prop shaft threads, then the slide hammer taps it out with the sliding weight unless the cam is not cleared then it wont

[Eluder1]

Sorry I forgot to re-read post on the puller on prop shaft! But the main question is HOW do I determine if shift cam is out of the way???? Looking into unit which is in nuetral I ca see the elongated cut out in shaft turned at a 20 degree also I can not reinsert the shift shaft so I think the cam is somewhere! Thanks...

i just did a verado case and the same thing happened, was the thrust ring between reverse and the bearing was stuck in the case-salt got between the ring and the housing, was able to use a puller jaw on the slidehammer, and got it into the thrust ring and pulled it out.

Yes that is what I believe happened! How or what do I use to attach to the bearing?
With prop shaft in the way my pullers are not long enough also to grip underside of bearing! Thanks, Eluder1.

[Dave Strong]

Pull on the prop shaft, put the carrier back in with no ret nut to make sure you pulling straight and not off to one side.

[Eluder1]

Dave, I tried that several times. One thing is that I can not rotate or move the Thrust washer and I need to make some kind of puller to hook to the bearing. I do not know if shift cam or somthing else is preventing the prop shaft from comming out, also will it come out if bearing is still in?
I can move prop shaft in a little and tried all methods! As for now it will have to wait for two weeks It's vaction time! Thanks for all the input and to mrcrsr who had the same problem and wainting for an answer on what he used as a puller!!!

Slide the bearing carrier back in, put a couple 1/4 inch metal plates across the housing opening (I use a spanner nut tool for an alpha) slide the prop on the shaft over the plates and tighten the prop nut slowly. It'll come out.

[Eluder1]

I would love to do that but I do not know about the shift cam and by doing that won't I destroy
the case?
anybody know about a Johnson carrier puller it looks like it might work to get a grip under the
bearing

Some of the best have posted in on your thread - if your unable to get it out consider paying someone to do it.

Please don't take this as flaming you - I've followed your post(s), and the advice is spot on.

It all good!! Always a better way to skin a Cat though.
Main concern Shift Cam--Damage to Housing if not out of position-that is why I want to go with Bearing removal--I found a way but you destroy the Bearing which is better then the Case!
Thanks, to all who replied!!! Happy Boating and you will B rake O ut A nother T housand!

u can also try to get in w/ a long punch and tap on the thrust ring to try to break it loose. i have a bunch of puller jaws here, i ground down a long one and was able to fit it in between and pop out the ring. if u need to get creative u can always make a puller jaw of sorts, and attach it to your slide hammer

[mrcrsr]

i just reread your post, why not just grab reverse bearing w/ the slidehammer- grab the outside of the bearing rite where it mates up w/ the gear and give it a couple of good wacks- either the whole gear/bearing/ring will come out or the bearing will come off reverse which would give you access to the ring.

[Eluder1]

The prop shaft is one interference but the clearence between the the bearing and thrust ring is nill-I plan to heat up outside of ring area and bang on the out side with a 2x4 and maybe attach some sort of thin rod/wire under bearing. This will have to wait for two weeks for when I get back on Vacation, I would like to talk to you when I get back via phone! Thank you for all the advise!! Eluder...
