- Here we are restoring an Yanmar L48 diesel engine which came out from a generator. This engine had a constant oil leak from oil filter which was caused by a drill hole, made by the previous owner due to a busted thread of a bolt. So I had to re fabricate that damaged piece with melted Aluminium. With some of gasket sealer it came out as leak free. Also I had to replace the main crank bearing due it's warn condition. Enjoy it.

I love time lapse mechanic videos, I am working on an L100.
I have 1 of these engines ive been saving for several yrs now and Im clueless with anything diesel.. really hope to dive into mine at some point... Id love to put it on a yard cart or old lawn tractor possibly...
They are really very simple engines. Only real complicated part is setting the injection timing. It's only complicated because there is not much info on how to actually do it. I just rebuilt a Chinese clone of an L100. Haven't run it yet. New piston, rod bearings, head, muffler, rockers, lifter tubes, pump, line, and injector. Bodgejob coffee table rebuild with Chinese mail order parts... what could go wrong 🤣 she'll go or she'll blow
Great video, I think I can rebuild mine thanks to you.
I have this same engine its vrry hard to start,
The tappet (rocker) cover has four bolts. The three smaller bolts fasten the cover to the cylinder head. What is the larger fourth bolt used for? What is the port used for?
Boa noite amigo. E você pode me tirar uma dúvida sobre este tipo de motor .Estes modelos de motor tem suspiro ou não?
... good job bro, how many hours of your time took this diesel engine?
I think around a week. Because there was a crack on the crankcase nearby the oil filter. It took me a little longer to refabricate it. If you don't have any troubles like that, it'll take around two days if you can find parts easily. Check my other videos also. I have more restoration videos on my channel.
Is the oil pickup screen in the block a big issue/cleaning? I’m looking at some used L70s for my old tractors & am looking at buying 3-4 of them. Is there anything I should look for when examining them? They place I’m looking at has tons of them/hundreds for a bulk complete core price.
Nothing much. If the engine starts perfectly, that's it. but when the engine is running , if it makes some white smoke or blue smoke, then you have to consider. That means a low compression, bad piston rings or bad injector signs.
I have a 1998 polaris sportsman 455cc diesel need some help or some one to work on it get it running anyone know someone that could help
The engine block on this thing is so small. Well no ignition coil, it’s an OHV, no spark plug, & no carburetor. Well compared to a Kohler K301 it’s pretty small.
This is a diesel engine. So there is no any carbs or spark plugs.
I have some work I need done. How can I contact you?
Clean yes restore no
whats the liquid that you used to clean the engine parts?
Basically kerosene and a tooth brush
any chance you know the torque specs for one of these engines? I have one Im ready to put back together
Actually I don't know accurately. When I was restoring this engine I hadn't a torque wrench even. I just hand tied it as I feel. But be careful when tightening crankcase. Because it's made of aluminium and slight over tightening will rip off threads. Check out this TH-cam channel. He is mentioning torque specs in his videos for this kind of small engines "th-cam.com/users/RedBeardsGarage"
thank you so much
