Removing the head bolts the hard way


How would you like to find these 10 bad boys in your bed? Three lengths, depending on where they go. It took us about an hour to get all 10 out, We used a 6-point, 3/4" socket on a 16-inch breaker bar and we have to say that they were difficult to bust loose. Our bet is that they've been in there since this boat was built.

We began by taking off the rocker arm assembly from the hull-side of the engine and stashing those parts away with everything kept in the same order. The pushrods - actually all of the valve train parts - looked fine and quite clean.

We also removed the alternator and a couple of other cooling hoses that will get in the way once we pull those old heads off.

When we got down to those inboard head bolts, our morning friskiest faded fast. Those bolts are hard to get off. Next step is to get a longer breaker bar or, failing that, a quick change of underwear. We really don't want to walk funny for the next week.


We're also going to have an issue with getting the old heads off and the new heads onto the boat. The heads weigh about 35 lbs. each and we're going to have to get some help picking the old ones up to the cockpit, then up to the deck and then down a ladder to the ground or to the swim platform, where they can be taken off.



Sunday: A bigger breaker bar does it
It's amazing what happens when you use the right tool. We bought a 25-inch, 1/2-inch drive breaker bar at Harbor freight on our way to the boat.  $12.95 well spent. The remaining head bolts gave up without any issue. Size does matter, it seems.

We also disconnected lots of little things that were bolted to the heads such as the dipstick tube, the lifting rings and the box that contains the engine circuit breaker. Once the heads were completely disconnected, they didn't exactly jump of the block. We pried and tapped but no, they aren't going to come off without a fight. We'll put some muscle behind it next weekend and see if we can get them off.


Yes, this is taking a while
We know that some of our dock mates could change these cylinder heads in a weekend or less but unfortunately, we can't. We captain a desk all week, thinking of amazingly effective promotions for our clients. On Saturday morning, we put on our old clothes and headed to the boat. We haven't swapped heads in more than 15 years so we've gotten a little stale (and older). Don't worry. We'll get this done.

In the meantime, we post these blogs and their associated videos, which we enjoy planning and editing. No Academy Awards, but it still helps us keep up with how video is done these days, and of course, for those of you who know us, it's a way to keep in contact over the winter.
