Reassembling The Big V8 Roiline H884 Onan 140 Generator Pt.1

Time to start putting this thing back together. Should have verified the valley gasket was correct months ago!

[@jeffhall3455]

mike i have been watching your videos for a while i am a generator man for 33 years man you are awesome you are very detailed and very rounded

[@hillonwheels8838]

In the Navy whenever we took something apart on the helicopters it would get torqued together then after a number of flight hours we would do a torque check to make sure nothing is moving. So I consider what you did on the heads to be a Torque Check. Great job

[@butler386]

I admire your ability and intelligence to work on small to huge engines. I do not know where you obtained this knowledge and skill but you should let all of us know more about your background. With this large engine can you order the correct gasket? You have put so much time and effort into this project make it perfect as you usually do. Thanks for sharing.

[@stevenormandin2059]

this video is like good thriller movie I just can't wait to see that beast up and running :)

[@rickhaass1133]

thought your mech gov delete plug was a pretty cool idea - great job sir.

[@austinkreller7592]

Permatex one minute gasket, and use a few pieces of gasket paper on the corners to act as a spacer so you retain the original gasket thickness. That’s what I do when I can’t get the proper gaskets, works like a charm and you can even trim the material after and you won’t even be able to tell it’s not original.

[@MostlyInteresting]

I would put a bit of gasket at each bolt as a spacer though. So you cant bend the cover.

[@28YorkshireRose12]

I'm glad to see this project again. I wasn't sure if it had fallen by the wayside. It's funny though, how often we can fall foul of things like gaskets that we think should fit, only to find out that they don't. We even had a problem with a Ford V6 Cologne engine and its water pump. Same engine, two different pumps. Even the guy at the parts depot said "I'll laid odds on this being the one" and gave us the most commonly found pump. Get back home - wrong pump. It all fitted up apart from one bolt hole and a water bypass channel. It happens! Can't wait to see/hear this puppy having fun on your load bank!

[@jodiburgett7546]

For the valley cover I would use number 3 aviation grade form-a-gasket.

Great to see this continuing Video of this engine rebuild by this skilled gentleman mechanic looking forward to Part 2.

[@jettpro6647]

Why can’t you just use some “right stuff” sealer since it’s just the lifter valley covers? Glad it’s coming together, great work Mike!

great job Mike, one step at a time .. I like the plug you made for the governor ! ENJOYED

[@rupe53]

So far this has been an interesting project and will be waiting for the installation of whatever gov assembly you choose. One thing I always do with VC gaskets is use sealer to glue them onto the cover, but on the side you DON'T want to stick I use a little oil or light grease on the surface so the gasket doesn't break on the next service. You can also use a VERY light coating of silicone sealer and let it dry for 10 minutes before installing. Same idea. The gasket won't stick to the head next time you pull the VC.

[@GIGABACHI]

Lifter valley cover sealing blues: Grey Silicone is your friend. Use a fine bead tho. We use it on diffs, timing covers and other oil exposed parts all the time and it stands up pretty good to all, even the slippery synthetic ones. 👌😎

You can check those lifters by setting them on a piece of [flat] glass and seeing if the wobble. If there is no crown, the will quickly wear the camshaft.

They made this engine in a 844 ci also. I. Western Kansas these were used for irrigation engines. One man who was a service man at Seyb Tucker had served in the Army where they used the engine in Army Trucks. Irrigation engines ran off natural gas the military I think were gasoline. At one time we ran six of these engines. There was a factory in Tulsa I think it was Roline or LeRoy just west of downtown on the north side of the Arkansas River They were bought out by another company then discontinued to get rid of the competition in the early 70s

[@cesargallo7424]

[@PaulHigginbothamSr]

You must be going to use an electrical governor. Seems like more dependable to me and better load following. It will be interesting to see if it will keep to 1/4 cycle to 1/10th cycle accuracy. When the military ran the huge 16 cylinder behemoth gensets if there was a power failure in the Seattle area McCord Air force base radars had these gensets up and running in less than a tenth of a second matching the wavefront of the cycle exactly so the radar would show no glitches. Air start.

The initial friction can give you wrong reading when using a torque tool. That why we usually loosen the head bult (or nut in this case) a little. About 35 degree just to get rid of the start friction.

[@the_hate_inside1085]

I heard cork gaskets benefit from being soaked overnight in engine oil, prior to installation.

[@patagualianmostly7437]

I'd go with that....with such a "traditional" type engine. But then his "locating" silicone on the upperside wouldn't work so good. So I'd go for the soak......place the gasket on the heads...and lower the covers down. You could always use threaded bar (or simple bar dowels) to keep the gasket in place.... replace them one at a time with the correct cover fixings.... Sorted. Cheers.

[@BOBKB3NZX]

I know it may be too late. But I'd really like to see that Gov delete with a longer bolt thats castleated. Or just nick a longer nut down to install a cotter pin. OR flip the bolt and just drill the end to accept a pin so that no matter what it is prevented from coming apart in the galley. The parts im not so much bothered about but the loss of oil pressure is a concern.

[@kooldoozer]

All of what you said, and I just don't like a 1/4" bolt inside the engine. I know there is no load on it, but the hard vibration and harmonics with drive gears and combustion events, that is a lot for a 1/4" bolt to endure, just from being present in that environment. I would go with a 3/8" bolt, just to be sure vibration does not start a metal fatigue situation. I am an engineer and I know it 1/4" is strong enough, but I also have seen a lot of weird stuff break when vibration was present.

[@gabe1254]

@@kooldoozer Agreed, we recently installed VFD’s on some 500hp screw compressors used in anhydrous ammonia refrigeration system. In 6 months we’ve had at least a half dozen schedule 80 nipples crack and start leaking. When those compressors run through 30-50hz it picks up some nasty harmonics. Scary because total system capacity is around 50,000 pounds😐

I was told while learning to use a torque wrench that using the two pop method over torques the fastener

[@patagualianmostly7437]

mmm... I too wondered about that. The first click is surely the only click required...? On the other hand, I'm not convinced that the "Double Click" causes any issues. (Reminds me of that Rod Stewart song: "First click is the deepest...." Sorry.) Cheers.

[@dtimboggs]

Patagualian Mostly my understanding is that every click adds a little torque. The equipment I service has specific torque specifications to keep stuff from coming loose. Over torquing a fastener adds undue stress on the fastener, possibly causing premature failure.

[@chuckmackenzie8753]

Does your barring tool have reduction? I see you turning input clockwise which would make engine rotate CCW if direct drive. Also, why not use go-nogo feeler gauges on valve set, it’s more precise & not subject to “a loose .016” terminology?

[@Max-yj4sp]

Why not just use rtv on the valley cover? Not like the mechanical clearance matters now that the governor is gone.

[@korvtm]

Might be because most sealants that I have used will leak eventually.Case in point Hyster forklift,where the engine and transmission were joined,factory used a sealant instead of gasket,every one of them leaked after a few months.We would even ckeck the torque on the attaching bolts,before putting new machine in service,did not make any difference.Engine valve covers were also factory installed with sealant,would start leaking,only way to stop leaks was to install gaskets.

[@Max-yj4sp]

@@korvtm I've always had good luck with rtv in automotive applications. Could be that the sealing surfaces were undersized or there was too much flex in the castings in the application you mention.

[@patagualianmostly7437]

Not a huge fan of RTV....but I take your point for the valley gasket...not having the correct thin paper job to hand...yes...a thin bead of that is all that is required: There's little or even zero pressure involved in that area anyway. (But not on the rocker covers... please. That is a definite No-No!) Cheers.
