    Straight 6 Cylinder Engine

    I pulled the head today to see what was wrong with number 5 cylinder. I mounted the head on the valve test plate and applied 60 pounds of shop air. I expected that the exhaust valve was the culprit and needed some more lapping. But there were no leaks from either valve they were good. I...

    Straight 6 Cylinder Engine

    Yes it does run but there are some issues that I want to iron out first before the video. The cooling system is working better than I expected except for the radiator fan. It is really wimpy so I have another fan on order. Number 5 cylinder is not contributing anything it is just along for...

    Thank you Minh This is a piece of poplar that I am cutting out for the electronics box on the big router. Sanded, stained, and finished with spray poly. Here it is mounted to the board with an aluminum cover and a off/on switch. Thanks for looking Ray

    Straight 6 Cylinder Engine

    I attached a brass weight to the carb throttle arm so it would stay in the idle position. I added a brass bit to the idle adjustment screw so you could adjust it with your fingers. This is the same setup I used on the 4 cylinder model and it worked very well. Sorry I only got a picture of...

    Thank you Chuck for the kind words. Now if it will run as good as it looks. The fuel system is next. Ray

    Straight 6 Cylinder Engine

    Many things came together today and the cooling system is declared complete. This is the cooling water header tank. Installed the radiator and fan. I hooked up the hoses and added some antifreeze. Would you believe it there were no leaks. The pump moves a good stream of water even at 600...

    Lawn work this morning but I did get the engine mounted and 4 rubber feet mounted under the board. Thanks for looking Ray

    I use this module but with a different hall sensor for my distributor type models. Thanks for asking Ray

    Straight 6 Cylinder Engine

    I decided to work on the exhaust next. The local hardware store has some 5/16" inside diameter tubing with a wall thickness of 0.014 that has a gold finish and kind of looks like brass. A 3 foot piece is $7.49 so you can tell it isn't high quality stuff but I fill the pipe with a low melting...

    Straight 6 Cylinder Engine

    I got the new timing belt I ordered and installed it today. It has the same number of teeth and they are of the same distance apart as the original belt had but it could have been 2 teeth shorter. I just moved the belt tightener over to compensate. I had two of the original belts and I tossed...

    Straight 6 Cylinder Engine

    Thanks Lloyd this is my 16th model engine and I find I am more careful when working on the engine when it looks good. That doesn't mean that I haven't had to repaint some parts and many touch ups with the brush. Painting early encourages me to do a better job. These are the main parts for the...

    I cutout the distributor bracket from a solid piece of aluminum, painted, and installed it along with the dist gears. Thanks for looking Ray

    Straight 6 Cylinder Engine

    Thanks Doug it has improved the water flow. This is my first engine that I plan to have cooling water in the engine full time. I haven't worked out all the details yet tho. Thanks Lloyd A lot of other thinks happening over the past few days but was able to get started on the distributor...

    Straight 6 Cylinder Engine

    I should have put a smiley face after that comment. Thanks Lloyd I decided to just make a whole new water pump with the vanes curved the correct direction. The first one pumped water alright but may have been a little weak so I went bigger with the new one. New versus old housing. I also...

    Straight 6 Cylinder Engine

    Things don't always go right! If you look at the picture closely you can see the timing belt tensioner is on the other side. On most of my models the flywheel is on the front of the engine and it turns clockwise. When I built the crank I set it up for the water pump to be the front of the...

    Straight 6 Cylinder Engine

    The valves are threaded as are the keepers but not all the way through. The final height of the exhaust valve is adjusted by tapping the keeper a little bit deeper and then rechecking until I get the same height. I start with the shortest valve and make the others conform to that height...

    Straight 6 Cylinder Engine

    I am going to let the paint cure on the flywheel another day so I don't mess it up. Maybe tomorrow. I cutout the six cams today but I didn't get any pictures. This is an older picture showing how I make my cams on the CNC. All lined up but not timed yet. Earlier I had thought the cam...

    Straight 6 Cylinder Engine

    Thanks Lloyd The needle bearing have a hard shell. I packed some grease in them before assembly but I will give them a squirt of oil when needed. Had to mow the lawn today but I was able to get this made. I cut 1" off of this rusty chunk and made a flywheel. The inside is made of aluminum...

    Straight 6 Cylinder Engine

    Thanks Minh Thought I would continue on the valve train so I cutout the cam supports and made a brass bushing for the cam belt drive pulley. I installed needle bearings for a cleaner look in the cam supports. Side view of the 3/8" cam shaft. I had this timing belt left over from a previous...
