My cutlass bearing is in a tube extending back to the hull and then it is not possible to use a puller. The current replacement method is to remove the prop and so the shaft and then damage the cutlass bearing until it comes out. Has anyone experience with leaving the cutlass begetting say 10mm protruding? I then might be in hereafter, able to supersede by only removing the prop, loosening the cutlass begetting chow screws and so getting a pipe wrench onto the protruding part. any comments on this idea?

As soon as y'all grab it the force per unit area will be on the shaft. Not sure that this method volition work.

You would likely be back at cutting it upward with a chisel. Fifty-fifty if you did manage to turn it you lot however demand to pull information technology out, and remove the prop to replace it. My begetting has a loose fit, and I creepo it out past removing the shaft and so connecting a claw upward beyond the bearing down to my truck trailer hitch with a come up-along. You might exist able to drill a couple of holes in the protruding begetting that then allowed you to claw on to it and pull in an otherwise similar fashion. __________________ Never permit anything mechanical know that you are in a hurry.

The yard cuts a groove in the contumely shell near one end then installs the bearing with the groove exposed. When it is time to pull the cutless bearing out, they grasp the groove betwixt the jaws of a bearing separator (bearing splitter) and jack information technology out using the two threaded holes in the separator. The bearing separator should catch a significant fraction of the cutless bearing circumference and be the proper size. My son-in-constabulary has done similar with a similar jury rigged device (and without the groove) made from two parts from a pair of Advance Auto frazzle pipage U-bolts and some bits from his garage.

I have to remove my engine and pull the shaft into the boat equally the rudder prohibits pulling the shaft. Or driblet the rudder... thats even more hard as access to the rudder log is almost incommunicable unless youre 16 years erstwhile and tin can bend like a pretzel and work by touch only.

Neb I managed to practice this merely didn't need the bearing splitter, once the set screws were removed, it came out easily, mayhap abit besides easy. I sanded the new bearing shell and inner tube, removed the sending dust with acetone. Then a light blanket of thinned epoxy and slid it into position with a scrap still to push in 1/2". Be sure to dimple the bearing beat and reinstall fix screws, I used i/four twenty X 1/4" SS for this, very important to do this footstep. Be sure to bank check your alignment in vitro. Hither's a picture of the finished procedure. SV Deject Duster Fastened Thumbnails

Peculiarly if the coupler isn't newish. These couplers are a lite printing fit to the shaft when new. Pulling can be damaging, if non impossible. Y'all would so have to cut it off and at that betoken you'd pull the shaft. Information technology took 1 24-hour interval to do this repair on my vessel. SV Cloud Duster

Hither's a picture of the finished process. SV Cloud Duster Thankyou very much, This is the answer I was looking for. I�m going to do something similar and then the cutlass begetting tin be removed by just removing the prop and so pulling the exposed part of the bearing.

Registered User Join Date: May 2022 Posts: 2	Re: Cutlass begetting removal without removing shaft I had my cutlass bearing replaced at Sadler Point Marina hither in Jacksonville, Florida on a 1978 Whitby 42. the existing cutlass was install incorrectly and we had to remove prop, and pull the shaft to remove. When reinstalled, the mechanic made a point to exit the cutlass bearing sticking out nearly 10 to 12 mm then the process to remove in the time to come would not require doing more than removing the prop. I too take an enclosed prop from rudder design which does not interfere with removal of the shaft. When rudder is positioned to either side, information technology leaves ample room to pull shaft straight out.

Registered User Join Date: Sep 2022 Posts: 52	Re: Cutlass begetting removal without removing shaft I am curious how this turned out for the OP? I am in a similar state of affairs. 57' motor cruiser needing a cutlass begetting replaced. It has a long shaft tube so accessing from inside is not an option. I would prefer to not have to pull the shaft and all as it's an older gunkhole with a long shaft and coupling isn't in the best shape. Also I don't think the shaft would come out without removing the rudder. Any recommendations or advice would exist profoundly appreciated!

Longer shafts such every bit the boat yous pictured may fifty-fifty have a pillow block to support the forward finish from sag. You'll have to look at the centerline of the shaft to see if it volition clear the rudder, 50/50 run a risk it will. I think yous'll have to haul and remove the shaft for this ane, merely more detailed pictures would help here. My advise is if yous need it bite the bullet and do it. SV Cloud Squeegee
