Perkins 4108 help

Does anyone have a suggestion on how to separate the head from the block? I have the bolts out and have everything striped except the exhaust manifold which I can't seem to break free either.

Re: Perkins 4108 help

I have a 4107 and when I removed them in may I had the same problems. On the exhaust manifold I just used a little leverage to get it loose. On the head I have a large crowbar and picked a point to again lift using leverage. It is just stubborn but remove the exhaust manifold first and be double sure everything else is disconnected. Exhaust manifold is cast so could be cracked easily. Head is heavy and robust.

Hi i have a centre cockpit seadog 30 with 4107 under the cockpit boards,had the same sticking head problem,the solution was to rig shear legs over engine and lift head with chain block,make sure your engine mounts are good and take the lifting gradually,worked for me.all the best.Ronnie.

Re: Perkins 4108 help

Ive found that a Nail Puller, ya know the type, L shaped. I grind down the flat end a little to make sure it get between the head and the head gasket!! a couple of taps with a fair sized hammer or Mallet will free it up and make removal a lot easier. Just a old trick and has aways worked for me.
