How do I get the Drive ram pin out?
 

I have no idea what it's correct name is, but I need to get the big rod at the end of the drive where the hyd rams bolt to, out.
It is well and truely stuck in there, and it looks like it isn't supposed to come out. Problem I have is that it's the older model Bravo 1 drive with the non adjustable trim ram end limit so there is no oval hole, just the rod in a round hole that is well and truely stuck.

I have tried a hammer. Now the threads are damaged, but they were stripped anyway so any other ideas would be helpful. Is there something else I need to remove first??

I have the drive off the boat, I just need to replace the front pin / rod thing.

Any help is always appreciated.

Heat the aluminum up ,,,but easy and just hammer it out,,,looks like it is seezed in ther pretty good .:eek:

While u heat it take some big pliers and turn it to break it lose !!

Cut the treaded part off flush with the bar stock. Get a good size Bosch Hammer, use a blunt end bit and buzz it out.
Oh yes, it's true!

Lay the drive on its side and spray PB Blaster on it then again in a couple of hours it should tap out.

Looks like it seized from dissimilar metal corrosion. Try all of the above. Maybe an air hammer as well.

Thanks lads, I'll give all of it a go and let you know.

I've got a replacement pin so I don't care how this one winds up! I'm going to replace the other end while I'm at it as well, but apparently it has circlips on it so I'll pull them off first before I lay into it with a mallet!

By the way, I'm going to wreck the paint job, what's the best paint to use to re-spray the drive? What primer do I use as well?

Thanks again, you lot are life savers!!:drink:

Cheers,

I've had anchor pins stuck like that before, they are not fun to get out. Heat it up, lube it, beat the piss out of it. It's the only way I know!

Instead of pushing the pin out why not try pulling the pin through the housing...put a bunch of spacers on the other side and tighten an exisitng nut down on the spacers...
even if you are trying to smack it out..this preload will help you lossen the pin...

Another thing I've found works is getting a pipe wrench or good vise- grip on it and try twisting it loose. No matter what you do at this point, you will most likely end up hurting the pin to get it out.

Are these supposed to be difficult to get out? When I tried to install a tie bar, I had a b!tch of a time getting the rams off and trying to move the pin. Then once I got that far, I realized I had the wrong hats....

Always keep them greased,,,,,,The should move easy and i always take mine out once in a wile and stick them back in with marine grease !!!!

Helps !!!:ernaehrung004:

Cut the pin flush and drill a 7/16 inch hole in the center as deep as you can. Then drive it out with a drift pin in the hole. PB Blaster or Kroil works well Good luck ,Paul

Soak it in Coca Cola! When you see how it works you will never drink it again. No joke

Coke Cola I seen the guys from the gas company pour it on the gas valves in the ground to loosen. If you use the flame wrench (Torch) The hand held Map gas torch work good, they take a little while longer to heat the case but they are much more forgiving than the big flame wrench (oxg/acl). With the big torch its very easy to go into case melt down.

Well, thanks for all the input lads!!
I managed to get the bastard pin out!! :drink:

She was deffinately in there pretty good and tight, I ruined both thread ends, used a butane torch, a big pipe wrench and a mallet to it to get it to budge. Once it moved a tiny bit, I filed back and then sanded smooth one end of the pin and laid waste to it with a hammer to get it to pop out the rest of the way.

Looks like there was some loctite on the shaft, along with a shed load of corrosion and the gearcase had been painted with the pin in!

Now, what kind of paint do I use to respray? I have some anti corrosive etch primer and some corrosion preventive gloss block enamel. Will that do the trick?

Thanks again all. Great suggestions and it worked!!!
