Part 9 of a multi-part video series:
Replacing the Timing Belt and Water Pump on the Honda H22A1 Engine in a 1995 Honda Prelude.
Content of this video:
Recap of how the crank pulley/harmonic balancer was finally removed with general tips on handling difficult bolts like this.
I ended up hiring a heavy equipment mechanic who was working on some bulldozers up in this part of the mountains and I saw him on our road and flagged him down to swing by and take a shot at this bolt. So he ended up having the exact same impact wrench as me .. however .. he had a whole heck of a lot more AIR PRESSURE. While my little air compressor might get up to 100 PSI effective pressure on a good day and just for a few seconds, this guy’s monstrous compressor in his monstrous crane truck had 225 PSI in large tanks that never even faded. His air compressor was driven directly off of his DT466 International Diesel engine. Man it blasted his wrench hard on that bolt. Sounded twice as fast in the RPMs as my little compressor could provide and sounded a LOT more powerful like that and by the way it jerked in his arms it was obviously applying some serious blasts of torque.
THIS DARN BOLT EVEN GAVE HIM A LOT OF TROUBLE! He tried 2 or 3 good shots at it. Then he switched his wrench to the tightening direction for 2 reasons: 1. in case the bolt was threaded in reverse although I knew it wasn’t. 2. Sometimes a way to free a stuck bolt is to actually try tightening it a little bit and then sometimes that can help break it loose. Well on is 5th try or so it came off. What a great feeling after all that ordeal. Cool guy too and he was only going to charge me a half hour but I insisted on paying him a full hour because it was pretty much a full hour and he really did a lot for me and had to maneuver his big truck up our wacky deep-ditch-lined narrow roads.
About the attempt I made with the propane torch. Folks say that propane is not even hot enough for this and the trick to free a bolt with a torch means using an oxy-acetylene or similar for a LOT of heat, not a little plumber’s propane torch. Again the rubber in the harmonic balancer makes this a bad idea.
So, you better have a really good powerful impact wrench. Ours are Ingersol Rand 600 ft lb models.
You better have a SERIOUS amount of air pressure like 200 to 225 PSI and a big tank on your big compressor so that air pressure doesn’t drop too fast when your tools are running.
As much as I hate to buy specialized tools from car manufacturers and as much as I hate fighting with 6 foot breaker bars underneath cars jack stands on a slope on gravel .. that Honda crank pulley tool is seeming like a better idea now. I wonder how hard it really is to crack that bolt using one of those? Has anyone ever had to do hand to crank combat with one of those and can say how hard a sticky one is?
Another good discussion of these and related issues at:

Anyhow, unfortunately I did not get any video of the heavy equipment mechanic getting my crank bolt off, and that would have been cool video. Man his crane/service truck was a big rusty old diesel monster but it did the job that’s for sure!
At the end of this video after covering the crank pulley issues in full detail, we remove the upper timing cover which is held in place by 2 10mm bolts. Then we remove all 6 bolts of the lower timing cover.
In the next video we remove the lower timing cover itself. Some cleaning of the engine and surrounding area and parts has already occurred, but there is generally a lot of thick oily gunk and dirt all around here especially on the lower timing cover and around the engine block and oil pan. Multiple passes will be made to cleaning everything outside of and inside of the timing covers and all removed and surrounding parts as we work and only a little bit of that cleaning was video taped. Citrus engine degreaser, water, alcohol, high pressure air, brake cleaner, paper towel, q-tips, small scraping tools .. were the things used for all the cleaning involved. Following videos detail the special issues of cleaning the actual mating surfaces for the water pump.

http://www.techbricks.nl technic LEGO pneumatic air compressor tested with a Mindsensor pressure sensor. The Compressor is powered by a RC Buggy motor. It has 4 small pneumatic pumps. One small pneumatic cylinder is pressed out when pressure is building up. At a pressure of 28 psi the cylinder push the pole reverse electric LEGO switch which turns off the motor. When air is released, the motor will turn on at about 15 psi. Take a look at: http://www.techbricks.nl/My-pneumatic-LEGO-projects/pneumatic-compressor.html

This is why you always pull a good vacuum on a refrigeration or air conditioning system before charging!

Operating the Husky 716 double diaphragm pneumatic pump.
the pump is operating at 40psi off a 5hp, 15gallon craftsman air compressor. I have it sucking water out of the bottom of a 5 gallon bucket, and simply pumping it right back into the bucket.

A Cambell Hausfeld air compressor that wouldn’t build pressure past 40 PSI. The “ring” in the pump had failed.
I personaly think that this is a flawed design overall.

I decided to tear this pump down and demonstrate it before binning it, I’ve already done a few vids on rotary compressors before but theirs no harm in doing more detailed ones 
Its from a single phase 240V powered 7.1Kw split unit that was scrapped because of a bad compressor motor.(short to earth)
