Other Slow Speed Diesels / Farymann 43F
« on: July 20, 2018, 06:53:09 PM »
Hello all, I am sharing a short video of one of my recent Farymann 43F acquisitions. That's a Listeroid muffler on it; I still have to sort the intake manifold and air filter, as well as the fuel tank.
I hope you enjoy it.

Engines / Now I've seen it all....
« on: July 02, 2018, 02:08:24 AM »
Hi guys, just wondering if anyone has ever seen this happen.
I just finished repairs on a Yanmar L100 air-cooled diesel. On Thursday  evening she fired right up on my first start attempt; feeling quite proud of myself I did a short video and sent it off so the customer could see the progress.
On Friday I mounted the engine to it's cement mixer and wound up the rope to start her. I yanked the rope and she started right up with quite a bit of smoke and rough running, and that's when I heard my son say "Dad, why is she exhausting through the intake?" Sure enough, that's what she was doing and I put my hand over the muffler and I could feel the vacuum as she inhaled.
Puzzled, I shut her down thinking it might be a fluke, and started her again with the same result. Quite boggled now, I thought maybe she is left-hand rotation, so I wound the rope in the opposite direction and gave her a strong pull. Exact same result except now the engine was running in the opposite direction. I shut her down and left her alone until this morning, all the while trying to figure out if I was actually seeing what I thought I was seeing.
By this morning I had prepared myself for some malady with the camshaft timing, but first of all I turned the engine by hand and felt as it came against something solid. I turned it in the opposite direction and eventually I felt the same hard bump. By observation of the flywheel I concluded that the bump happened every other revolution of the crankshaft which led me to conclude that it was either a problem with the IP, something was caught in the cam gear, or the timing was off.
Choosing easiest first, I removed the Injection Pump, and sure enough the "solid bump" was gone. It was a brand new IP but nevertheless I took it apart and examined it but found nothing wrong.
I then started wondering if the injector could somehow cause these issues, and after a battle I managed to removed it from the engine. At this time I used a piece of wire coat hanger through the injector hole, removed the valve cover, and by observing the valves at overlap with the piston at TDC I was able to determine that the cam timing was correct.
I took the injector apart, removed the needle and sprayed some Carb Cleaner into the nozzle and let it sit for a few minutes while I arranged my Injector Tester.  Not having the correct fitting to hook up the entire injector to the tester, I put the nozzle into an injector that could attach to the tester. At the first few strokes I could tell that the nozzle was not working properly, but I persisted and after a few more attempts I got a satisfactory Pop and Spray Pattern.
I moved on to the body of the injector and discovered that a previous "Diesel Mechanic" had not aligned one of the two alignment pins correctly, and instead of it entering its respective alignment hole, it had caught up on the body of the injector next to the hole and he had tightened the nozzle holder so tight that the pin had actually penetrated the injector body and mushroomed it's head as well! What a mess!
I happened to have a good injector body that was near enough that I could used the "Valve and Seat" from it to replace the damaged seat. I then used my grinder and "sharpened away" the damaged threads in the area where the pin had swelled them.
I then reassembled the injector and reattached it and the IP to the engine, checked that the IP was Popping the injector, and had my son give her a couple of good pulls and off she went.
Has anyone had similar experiences with engines acting this way?

Red Stone Engines / Does anyone know?
« on: June 18, 2018, 09:22:09 PM »
I've read the posts here and watched the videos on YouTube, but when I Google Redstone diesel engine the search leads back to same.
I understand that they were imported by 2 or 3 gentlemen in the USA and Canada, and they cannot be legally imported into the USA under the present ban, but who was the overseas supplier if anyone knows?

There is no such ban where I live and I am interested in contacting the supplier.

Thank you for your help.

Hi guys, I was sniffing around www.Smokstak.com and noticed this Lister Gas Engine for sale, if anyone is interested. It seems that enginads is the sales area for smokstak.

Listeroid Engines / Am I getting full rack travel?
« on: April 14, 2018, 02:03:36 AM »
Greetings all.
My engine seemed to be lacking power and I was having binding issues with the governor linkage anyway, so I decided to try replacing the yoke as per pictures I've seen here.
During this process I realized that the rack is not opening fully once all of the linkages are connected and adjusted per 38AC's method and I tighten the spring which opens the rack.
There is no external binding and everything is moving smoothly now, but about 60% rack is all I get before I can feel the internal governor sleeve reach it's full travel, so no matter how tight I make the spring the rack will open no further.
I have attached 3 pictures showing the rack in the No Fuel Position, Fully Open with the linkages attached but held open against the Governor Sleeve, and 100% open with the Vertical Linkage disconnected.
Does this seem normal?

Listeroid Engines / Hello from new member
« on: September 27, 2017, 06:47:32 PM »
Hello all, long time lurker and diesel engine fanatic here, situated in the Cayman Islands. Here are a few pictures of my current 6/1 Clone ST generator project. The disassembly, cleaning and balancing are done, many thanks to the members on this great forum. The engine and generator have been test run for about 1/2 hour with load but I still have a few minor bugs to work out. A video is soon to come.
