Help!! PCM Transmission swap with PCM V-Drive

[liquiddreams]

This job has been fighting me for weeks now. Just bought the boat a few months ago (2012 SAN) and the transmission cooler went out which got water in the transmission. It started slipping before I caught it. Decided to upgrade from the 40 series to the 80 series instead of rebuilding. Since then It's been one thing after the other. It took weeks to get the transmission due to the Pandemic. The prop was stuck on the shaft when I went to take it off. The previous owners must have never taken off, because it fought me. Even heat wouldn't make it pop off. I ended up buying one of the ACME C-clamp pullers (which is not easy to find in stock right now). Got the prop off finally and started on the inside. Got the transmission cooler changed out to the 12" one with no problems. When I went to remove the shaft coupler it moved about 1/4" inch and now it refuses to let go. It literally bent the puller trying to get it off. Scared to use heat due to the gas tank be in such close proximity.

1. Any ideas on how to get that coupler off? I can pull the shaft forward so the two couplers are separated, but the shaft one is still on there. I have been using a harmonic balancer puller.I thought about trying the ACME C-clamp on it, but I am not sure there is enough clearance.

2. I thought about just putting some wood blocks under the v-drive to support it and then removing it's mounting bolts to slide it back enough to get the transmission out. Not sure if this would work and I am kind of afraid that I am going to mess up the shaft or the strut. Any thoughts on this approach or has some done this approach.

I am open to any advice on this swap. I have worked on a lot of straight shafts, but this is my first v-drive. I really didn't think it would be that bad and if it wasn't for the shaft components I don't think it would be.

Any one with experience swapping a transmission out that had a v-drive I would love some advice or tips. Anything else I need to worry about? I have been taking pictures with the hopes of uploading them in the end to assist anyone else that does it in the future.

Yeah, that is where I started and it got me this far. However, only have a two bolt puller. I guess I'm going to have to buy that puller and see if it will help. I just applied heat to it a few minutes ago and it still won't budge. I am ready to get this transmission out, but this stupid coupler won't give. Frustrating... Thanks for trying though

Thru the v drive !!!!! that is some witchcraft (i read the other thread )
im going to read the alignment procedure for that, i can't even comprehend it.

its probably like other couplers tolerances, tight. Get that puller and hopefully you'll never need it again, but since you wrench, having it and the prop puller around could save the day or rather your vacation someday.

i was told about and used a product called tef-gel, lt is fantastic, stops stainless nuts and bolts from galling, used it on every nut bolt and fitting, even hydraulic.
when mine goes back together i will franks hot sauce it " put that sh!t on everything !! prop, coupler, keyways, everything.

Took another personal advice. I was able to move the ballasts and gas tank forward enough to get shaft out with the coupler still attached. V-drive is out and will be doing the transmission tomorrow. Thanks for all the assistance and more to follow as it moves along.

I was wondering if that would work when I read it on the other forum. Glad you got it out.

Well, v-drive and transmission are out. I was going at a good pace until I go t to the bell housing to replace the damper plate.I have removed all of the dust cover bolts and I believe all of the bell housing bolts. However, that thing will not come off. Any tricks to get it to break free? I believe it might be the pain holding it on, but I didn't want to go beating on it. Any diagrams or posts with picture you all can aim me to. I have searched the threads and nothing about a stuck bell housing comes up.


On a side note: Is there any where I can go to get the torque specifications for the install? Thanks in advance

No experience with this boat but plenty with stuck bellhousings. There’s usually a dowel pin or two and that’s usually what they’re stuck on. If you can get a diagram, try prying anywhere there’s a pin. Also get a big hammer. As long as you’re sure there are no more nuts or bolts attaching it, some heavy swings at it won’t hurt anything. It’s hard to really hurt a bellhousing.

So, I found another post about someone replacing a damper plate on a GM motor and there is a hidden bolt under a plate. Going to check that as soon as I get to the boat this morning. Thanks fornthe help and advice

Well, everything is in, but now the shaft coupler isn't seating correctly. Cannot get the shoulder on to even start the alignment. I have been looking for alignment steps on the forums, but so far I have not been able to find them. The coupler looks like an even gap all the way around, but it just want seat. Any ideas? I accidentally posted this on one of my other threads so it's a double post. Sorry

Well, it turned out the v-drive coupler had some pitting (even after wire brushing) that was keeping the shaft coupler from mating. Got it taken care of and if I ever do it again I will verify the mating of the couplers before trying to put in the shaft (Lesson Learned). Now, everything is in minus the rear ballasts. I took it for a test drive and it ran like a champ. Minus the PSS Shaft seal leaking. Will readjust that and make sure the allen screws are in the right notches.I took a lot of pictures along the way so I plan on putting together a DIY thread on what I went through. It was not to horrible of a job, but I ran into quite a few speed bumps a long the way.Thanks to everyone for the help and advice.

Well, I finalized the project and wrote the thread as promised. It is over in the DIY forum. Thanks to everyone that helped me through this.
