Purchased a Changfa R165 watercooled diesel engine, question about flywheel play

[Jesse McB]

Update! It's Alive! Well not quite lol, but it's fully reassembled! well here's a little Rant of excitement here for you all, i've had this thing for 10 years! And what it has like 2500 hours haha?   Long story short it was more work this time around then the first experience rebuilding this engine! I will post photos along with details on this recent rebuild asap! Hopefully by tomorrow! Every fastener replaced with high grade stainless steel, new alternator bracket, valve work involving seat grinding because I made a mistake on the frist rebuild! Resurfaced head and block, new cylinder sleeve, rings, valves, bearings, paint. Redesigned crank case vent using a tire air valve, a redesigned "loop fuel return system" using double banjo bolts will provide a "bleed free" fuel system.

keith71, what parts are you looking for if you don't mind me asking? I have basically every parts stocked for the changfa R165.  The best site to order parts for the R170 is yoycart.com A matter of fact all parts for all series of these water cooled and air-cooled diesels parts can be found on this site. I have a Full list of saved buyers and parts on a list in my account with this website, i spent days looking up every part for the r170 and r165 because they have so many product's it can be almost impossible to input the correct keyword in the search bar. Basically you may see irrelevant items only. I made about 10 orders now and have every part, a box full of parts for the r165 and r170 except crankshaft and camshaft only because i haven't ordered them yet. i'll send photos of these parts, so you have an idea  on the product's they sell.  it's actually crazy, if you buy 1 head gasket, its about 1.20 usd, if you buy 10 head gaskets i think its only $4 usd!? 40 cents a piece, and shipping is $4 usd. Injectors and injector pumps are average $12 usd a piece fully assembled ready to go! A fresh cylinder head with valves for the r170 are $16 usd, shipping will be about $50 -+ since its a heavy thing but a wicked deal still! A pack of piston rings go for $2usd each if you order 1o packs, so $20! 

I wonder if there's a way I can supply parts for anyone and everyone? I will be glad to do that, cheap prices too,  maybe ebay? problem, I cant stock every part myself but i do know a source for all the water-cooled and air-cooled 2hp to the biggest they get .... im guessing at 33hp?! I am an ebay seller, I think i may have a legit plan if folks are interested!

Hello JesseM,

Why did you need a new piston and liner with only 2500 hours on the engine?
Were you burning an "alternate"fuel ?

Thanks for the info Jesse. Yes I am aware of yoycart, they have everything for these engines. The main issue I see is you must enter the weight of each part in grams to get an accurate shipping qoute. None of the parts listed in the descriptions tell the weight of the item, very strange. So you either have to have your engine apart and weigh the flywheel crank assembly or what ever other part you need. Or you have to guestimate the weight and they adjust the shipping charge when they get all the parts together.

Anyway just read this entire thread again and was truly inspired by your work on this little r165. I will post a link on a complete R175 you can buy completely disasembled and you buil it at home.. Every part on the engine the block head gears crank etc everything.
going to try to get a price on that.

I really would like to upgrade to a R175 or R180 mainly because of the forced oiling with a real oil pump.. I know from reading some of Henry's posts he was not a fan of his R165.. He was not impressed withe qaulity of the parts.. I think the chinese build the bigger engines with more quality in mind.. IMO, but not sure

Jesse also was wondering how that water pump you used in post #88 worked.. I think it is the 12 volt 2.1 gallon per minute pump correct? I believe I have that exact same water pump

Wesepo is another place to get parts.. They carry just about everything for water and air cooled small diesel engines..  Shipping cost is on par with most all of the other suppliers.

I looked into buying an R175 as parts and the shipping costs were outrageous. Due to the engine block and cylinder head weight it can only be shipped via sea freight. They have to be shipped as part of an LTC (Less than container) load and extra handling is involved. Then there's the cost of Duty and Brokerage. Then additional ground freight from the port to your destination. By the time the engine is complete the freight costs come in nearly $850 - $950.

Thanks Veggie.. I was also thinking the shipping must be nuts all the way from china.
It is probably close to 150 pounds give or take..It is ashme shipping has gotton this expensive.. We could do so much more with these engines with easier access to parts. I think just a crankshaft and flywheel would be close to $150 usd. Thanks Keith..
