- Here, using a set of late Redditch 350 Bullet crankcases, I try to demonstrate fairly basically, how the lubrication systems work and point out the slight differences which can be found between Redditch and Indian types of engines.
Thanks Paul for the info my 1992 500 Bullet made it a lot easier to understand about oil flow of the Bullet .
Makes me drunk to follow the camera with my eyes, but all the things you discuss in this and most of your other videos tought me such a lot, more than any maintenance and repair handbook. Regards from Germany
Thanks for great info and tips! Cheers from Alingsås, Sweden. Enfield 500 1977
Thank you for this thorough and clearly laid out video, very helpful indeed!
Hey, steady on! With all that jiggling about you kept banging my virtual nose. A very interesting description and some great tips. Thank you.
Thanks Paul for this explanation. It teaches me how to maintain my Bullet 500 from 2007 properly and how to treat it to prolong its engine life span. I will make sure I warm the engine thoroughly before putting stress on it. I love these charming Bullet bikes and understanding how they operate makes me appreciate and respect them even more!
Thank you Paul.
Very interesting and enlightening.
Good stuff! The difference in the quality of the castings between the British made and Indian made engine cases is quite stark.
Great explanation. Thanks for taking the time.
Now I understand why those magneto drive cogs are needed.
Very clever well designed system.
Great video, very informative...thank you
Hi PAUL , dank voor deze zeer goede uitleg wat het verschil is , in het smeer omloop van deze beide motoren . De beste groeten aan de familie en jou , Roger.😉👍
Very interesting. I wish I'd have known all that in 1966 when I had a 350 Bullet. It was the one that got away ( sigh).
Seen a video from India on this very subject,a really old Indian mechanic teaching his apprentice.
In Hindi,so I was relying on visuals.
It was informative,but your video clarified everything perfectly.
Many thanks.
G'day from Australia, one of my classic English motorcycle's is a 500 Bullet and l found this insight into the working of the oiling system a real help in understanding more about this machine, thank so much, cheers mate, Neil 🤠.
I play about with Enfields here in Japan I have a 350 as a daily driver, stock standard enfield india Starts hot or cold more or less first kick so much so ,,,I REALLY REALLY need to give it a service ,,
Thats brilliant Paul. Hope the wasn't your best tablecloth!!!!
Ha ha, thanks!
Thanks for a lecture Paul, never fully learned about RE lubricating systems before, so found a few eye openers along a way. :) All together better system than I imagined.
Very well explained thanks 😊 👍, Chris.
Awesome! Brilliantly demonstrated 👏 it all looks very biological like a heart. Most enlightening, thank you 👍👌
These small innovative Italian companies designed and produced some absolutely incredible little single 4 strokes that were light years ahead of the British stuff.
Beautifully engineered kit. I love them. I own a Guzzi 160cc Stornello and 192 Galletto that made a Bantam and Cub look like lumps better suited to an anchor. Your Egg is a treat.
I have experienced Ducati and MV singles myself and much prefer the British ones, thanks. The Ducatis and the like are much over rated and have plenty of weaknesses of their own and many don't perform as the stories would have folk believe.
The oil pump plungers are double acting.
While they deliver they also draw in oil.
thats why there are four holes where the pumps are located.
When you show us how the unit 250s oil system works, could you put the cases on a still surface. This was informative and interesting and enjoyable, as all your videos always are, but I felt dizzy as the camera went one way and the cases went another.
Hi Neil, I thought that would be the case, but I hold the camera in my hands as I try to home in on what I am trying to show. I doubt it would work so well with the camera put down on something and then someone would probably complain about the sound being too low in any case. Can't win sometimes ...
Interesting tour! Thanks 😎
they`re an amazing bit of casting skill and then the level of
precision machining involved to make it all function as it
should, phenominal stuff really paul ! 🤔👍
I would love to see oil way/and pump modification for asbo engines ie an upgrade
nice sir 👍
Thank you
The difference between the floating bush and needle roller big ends is very noticeable when you prime the crank with an oil can via the quill bolt hole. The roller ones offer virtually no resistance, the floating bush ones take quite a firm press of the can to get oil to go into them and oil cans are capable of generating a surprisingly high amount of oil pressure. If I'm feeling particularly paranoid, when I prime the crank on mine, I leave the front drain plug out and oil the crank until I see oil come out of the drain, then I know it's fully primed up..
I leave that plug in, so that oil accumulates in the crankcase, ready to be flung around by the flywheels on start up.
Oh and I have some questions. I had ordered one of those fancy and shiny tappet covers from Hitchcocks and a new seal too but after installing it was leaking oil quite severely. I tightened the centre bolt but could not stop it completely. I returned to the old ribbed tappet cover and the old seal and the leaking stopped. So I have three questions: 1) Is there pressure built up in the timing chest? 2) Should the tappet cover be screwed on tightly or how to seal it properly? 3) Is the breather from the timing chest doing anything? Someone told me the breather hose was obsolete and I could just close it e.g. with a screw...?
Hi Frank, answering that could be a minefield, but I think you are talking about the small stub coming from the back of the timing case, which is found on engines with breather outlets coming from the top of the crankcase, behind the cylinder. If so, this was supposed to allow accumulated oil in the catch can to run down into the timing case, but that rarely happened with the standard set up. It can be blocked off, depending on what other breather modifications are made.
Here are some videos which may be of interest:

@@paulhenshaw4514 Thanks Paul, I will study the video. Although it mainly answers the breather issue but I am still figuring out why my tappet cover was leaking..
Hi I like your videos. Can you please let me know if we put a high pressure air like 120psi by the crankshaft oil hole by the timing side did it bleed through the floating bush side by the connecting rod end. I have an issue where I think the oil hole was blocked that’s why.
