Is a 1115 a 1115 regardless of who makes it
« on: December 10, 2020, 07:05:37 PM »
Maybe an odd question but call me cautious when it comes to ordering Chinese stuff so... I have a Laidong 1115 and am planning to buy spare parts via Ali-Express. I am assuming a 1115 head gasket, rings etc are all the same regardless of manufacturer... am I assuming correct?

Thanks

Randy

Incorrect. I know of at least 2 head gaskets for the "changfa" type 1115 engines. My Powermart 1115 uses a head gasket that is marked 1100. The  LaiDong 1115 is its own animal entirely.
Did you not get a complete parts and tool kit with your engine as shown.?
I have the issue tool and spares sets for both and checked the ring sets. totally different and not interchangable. Wasnt going to remove them from packaging to get a photo.  changfa type gasket on left Laidong on right.

Yes, I did get a kit with the engine but forgot all about it till you just mentioned it. I'll dig it out this weekend and see what I have. Thanks

Great, The LaiDong s come with the most complete spares kit and beside what is shown you should also have the huge ball bearing for the flywheel side. I bought one of the first ones John Ferguson sold before he sold out to Jim Calder

I also bought mine from John along with a Redstone. Both have been setting in my garage for..10-12 years (lost track of time). They are lined up next to my Listeroid. I'm now to the point in my life I can start working on all of these..1 at a time.

I built up a Cat/ST head a few years ago but was not happy with the vibration. I just tore it down and am going to make a new stand for it. Once that's done I'll do my 3 Cyl Kubota with the Stamford clone gen head. then..... I'll get on that Laidong. Just spent a few weeks insulating my garage, fixing my torpedo heater and cleaning up, so now I'll be able to work during the winter.

I think what matters is whether it's an older style or a new generation Yanmar copy.
38AC and Randybee1, I could be wrong but your LaiDong is not a standard "Changfa" or "JiangDong" older style engine.
I believe all the original Changfa style 1115 engines took the same spares.
The LaiDong which you mention is a copy of the newer style Yanmar singles. Probably with an aluminum crankcase ....yes?

This is where I got a spare head gasket for my ZS1130. I successfully compared the pictures and measurements to my spare head gasket which was damaged in transit.

Veggie, I know from your postings that you have much experiance with these engines but here is my small but enlightening journey with 1115 types.
The Laidong is all iron, very heavy duty and very high quality. A much different engine than all others for sure. As for the 1115 "changfa" types there are also differences as I found out about 10 years ago when my brand new 1115 marked as a Powermart had a leaking head gasket, so I thought. It was blowing coolant out the exhaust
 I had to order spare gaskets twice as then first 1115 gaskets had the wrong diameter fire ring. Turns out there is two(at least) sleeve configurations in 1115 engines. The gaskets that fit my 1115 also fit 1100s. Back to the coolant leak, turns out the gasket wasn't the problem. There was an internal flaw in the casting that leaked coolant onto the exhaust port. There used to be a fellow from Taiwan on here that was willing to source parts and ship. I contacted him about my head problem and he said same thing,, "all the same standard part." I spend 1/2 the cost of the engine to import a new head and guess what? it didn't fit.  Still sits on a shelf. I "fixed" the OEM head with water glass and its still holding today on my home stand by set.
Maybe it's just the 1115s that suffer from this but it has caused me to doubt any notion of they are all the same as it pertains to China horizontals.
