WooHoo, SD1130 Chinese diesel engine arrived this morning!!!

[rcavictim]

Wow this is a B E A S T .  Much more massive and considerably heavier than my mighty Changfa 1115.  I think this weighs 625 lbs.  Seems heavier.  It was all I could do today to get it safely into my shop.  I want to take some pictures after I rest my back.  I probably won't be able to walk tomorrow.  I was able to get this engine and a VW Rabbit diesel 1.6 L which I bought over the weekend from the trunk of my car to the cement pad outside my shop roll up door with my bucket loader.  From there I had to slide the two engines on cement into the shop.  It was all I could do to zig zag move the Chinese beast.  In comparison the complete VW engine was so light I could almost pick it up and carry it.  No access to use my engine lifting hoist today.  Too much 'treasure' in the way.  The shop is a mess.

I'll post some pics soon.  I am really eager to test fire this beast!

Hmmmmmm....
Similar weight and displacement as a GM90 8/1 Listeroid.
Slow it down to 900 rpm and it my become a gentle giant.
Especially with the counter balance shafts.
When you fire it up, lets us know how it responds at lower rpm's

240.0 kilograms book weight is 529.1 pounds.

Hauled in the trunk of a car?  What car, '67 impala?

Gary,

You are reading my mind.    It has a more massive flywheel than the 1115.  I was thinking that if it will oil properly at low speed, I could add some weight to the flywheel as you did successfully on your 195 and retard the injector timing a bit.  Maybe I can get enough power at 700 RPM for my needs.  

I have a 33" OD x 5" wide flywheel here I could hang on it.  With that this might be workable at 400 RPM.  I'd really like that!    My major fear/concern is that the oil system won't lube the lower rod bearing adequately at such low speed because of the way these Chinese horizontals are set up.  My JD175A (353cc IIRC) sounds so sweet at 500 RPM (has massive added flywheel inertia through the twin B-belt drive) but I suspect inadequate oiling.  At that speed it doesn't make enough power to be useful though, but the 1130 is 5X the displacement of the JD175.  Getting the governor to operate at such low RPM range would likely be another challenge.

This SD1130 has a real, automobile sized, v-belt driven alternator. The Changfa 1115 has a light weight, flea powered alternator built into the space between the block and the flywheel which can drive a headlight and charge a 12 volt starting battery. The SD1130 also has a belt driven coolant water pump as well as a full sized hopper reservoir.  It is easy to use as an evaporative hopper or add a radiator for a sealed system with antifreeze.

Until I have a chance to study this engine and the engine drawings I really have no clue about low speed suitability.  I wouldn'd add 250-300 (?) lbs of extra flywheel unless that crankshaft is extra beefy.  Perhaps I'd want to couple the existing drive to the big extra flywheel via a compliant coupler and have two pillow block bearings support the extra flywheel.

No, the VW engine was transported in the trunk of my 89 Toyota Camry.  The SD1130 arrived by 18 wheeler.  I miss my 1964 Chevy BelAir for a big useful trunk!

That SD1130 HAS to weigh more than 530 lbs.  Where did you get 240 kg?

Google. Had to surf for a number, that step up to 650#~ is a lot of iron but with pallet weight and crating very likely?

What's the deal RCA?  You get iron envy after reading about my Fairbanks? 
Sounds like an awesome rig!  Looking forward to some pictures and a report about how it runs.  Sure hope you can work that large flywheel into the picture.  I have seen engines with an additional support bearing outboard of the flywheel.  I think that was fairly common on some of the really big old engines.  Obviously alignment is critical, but I don't see any reason it couldn't be done if your crank is long enough.

congrats on the new beast!

PICTURES!!!! Please.
I need to see the beast.

Chris,

Iron envy is exactly what I got seeing your lovely BIG engine.     What I don't envy is all the hard work you have to do to make yours like new.  Mine has the newness factor as purchased.  I spent some time installing the belt driven water pump, muffler and air filter tonight as they had been removed for shipping at my request so that they couldn't get broken off.  The original crate was long gone and this engine was shipped bolted to a 4x4 foot pallet.  It was a store demo model.

There is no crankshaft to slide a flywheel onto. These China horizontals have a short tapered crank output end with a keyway and the flywheel slides on and then a nut gets torqued onto the threaded end of the crank pulling the flywheel onto the taper.  Any output power interfaces like V-belt pulleys get bolted onto a 3-bolt arrangement into the flywheel itself.  There are centering notches on the flywheel as well as the three threaded bolt holes at 120 degree centers.  My engine came equipped with a wide 10" O.D. flat belt pulley attached to the flywheel for those wide farm machinery belts like they use to drive sawmills and stuff.  The other end of the crank is hidden internally behind the timing case cover.  There is a Chinese engine similar to these others with two flywheels called the Redstone, but that arrangement is the exception in a Chinese single, not the rule.

I am aware that the Canadian EPA is going to close the window on importing these Chinese diesels in the near future and I wanted to make sure I got another one while I still could.  I've been watching this big engine on ebay for well over a year and when the price dropped from $1500 to $1000, I was tempted but couldn't spare the money.  When I saw the price drop to $800 a couple of weeks ago I pulled the trigger.  I don't know if this will displace one of my prime gensets now online or just become a toy and spare engine for just-in-case.  I guess that depends on how well it likes running slowed way down.

I hope to fire this up tomorrow and begin to get an answer to that question.

My booklet says the engine weighs 260 kg for the hand crank start only model.  That's 572 lbs.  Add the massive ring gear, starter motor, water pump, alternator, huge flat belt pulley and about a gallon of way overdone grey paint and it is easily 650+ lbs.

400 rpm might be a bit too slow. Lots of hammering.
Also lots of speed change per rev if you are driving an alternator.
Might make for some wonky looking sine waves.

You may find that at 900 rpm the current flywheel is adequate.
Try it out first.
Adding more flywheel to these engines is not easy. (Custom machining)
Perhaps add a flywheel to the devise you are driving, like the heavy flywheels found on the generator heads of the Lister Startomatics.

Yes, perhaps there is enough flywheel there for 900 RPM.  Oiling ought not be a problem yet at that speed either.  Testing will tell.  Putting the extra flywheel mass on the generator is also a working solution.

Fortunately I have an old SouthBend tool room lathe with a 16" swing to handle the flywheel mods.  The hammering issue goes down with retarded injector timing.  I blew a crankshaft ball bearing unit to smithereens on my JD175A operating slow with too much advance, or rather I failed to retard the factory timing from the high speed setup.  Learn by doing.

Congrats man! I have been watching it too and noticed it was gone. I saw an 1135 in Michagan two years ago and you are right, WOW lots more iron than a 1115.
Have fun

Thanx man! 

1135?!!! Never knew they made one that big.  Damn, here I was thinking I was finally king of the castle (as far as the Chinese horizontal singles goes).
