Royal Enfield Bullet 4 speed gearbox - converting to close ratio, the whole process step by step.

- Apologies for the repeat showing of the first couple of minutes, but they tie in with the rest of the material in this compilation, where I try to discuss and demonstrate aspects of 'how to' strip the 4 speed R.E. Bullet gearbox and fit a close ratio conversion - and a wide ratio conversion would be fitted in the same manner, for that matter.
I don't go into great depth about stripping and rebuilding the gearbox itself this time, as I already have video material discussing that, but most of what needs to be done is covered here and might be of some use to some wishing to carry out this conversion.

I loved watching you work, and learned a bit too in the process.
I know not many would say this to you, but I would like to thank you Paul, for your great uploads, that are easy to understand, and bring me so much enjoyment to watch.
I now understand why the owner wants a close ratio 4th.. as I never realised that this wolf in sheep's clothing, was a bit of a special!
As always another enjoyable and informative video.
I always wanted to put a close ratio gearset in the much modified 350 Clipper I had in the early 80s but they weren't available at the time.
On the subject of putting grease in the gearbox it was recommended on pre Bullet models to put a dollop into the recess at the bottom of the gearbox main casing after overhaul, I think the idea being to help the rudimentary felt seals they used from leaking, it was never recommended to add any grease at any time after this and it certainly wasn't necessary.
Yes gearbox internal work....look and learn,the knowledge,with Paul...
Good stuff.
G'day Paul, great job done, l had slot of trouble with the gears on my 500 Bullet rebuild so your approach is fine, well l have bought another Bike it's a 1960 BSA A10 Gold flash everything is there, lots of new parts just needs a finishing touches, cheers mate Neil 🤠.
Thanks Paul, I haven't seen inside one of these since I was 16 back in the mists of time.
Thanks for all you do, you are a truly humble and genuine person who is a wizard on the spanners. Keep it up and long may it continue.
Terrific job. Just love your no nonsense approach 👍👍
With respect Paul, the workshop manual for the Indian-made Bullets says "For initial filling up of gear box VEEDOL `00' grease is recommended. During routine maintenance, topping up may be done with SAE 50 oil. The capacity is 700 grams (Approx.) of `00' grease mixed with SAE 50 grade oil to a thick consistancy" The workshop manual for the Redditch-built Bullets, of which I have one, says similar. My 1954 350 Bullet, which I have owned since 1967, would piss oil out of the gearbox. I rebuilt the bike about three years ago and this time, packed the gearbox with the recommended '00' grease (very fluid) topped off with oil. I now have a gearbox that doesn't leak and changes gear perfectly after 3,000 miles. I have since persuaded my brother, who has a collection of RE twins, to try the same and he too is very pleased with the result. Just thought it worth a mention.
Thank you for your very informative videos, Lindsay.
Yes, I know, but the original Redditch manual says OIL, and, seeing as the Bullet was their baby, I prefer to follow their information. The Indians also forgot that the 350 Bullets like more ignition advance than the 500 versions!

@@paulhenshaw4514 as Paul has stated in other videos...and I have found out through enquiries...the semi fluid grease dodge was to assist with excessive oil leakage in India...due to heat !!!
Use sealed bearings and oil......SAE 50.Engine oil not hypoid...
Workshop Manual 1949-1955 350cc + 500cc Bullets Section E1, Page 3, Subsection 5, Paragraph 7: "Make sure all parts are clean before assembly. In normal climate the recesses in the gearbox should be packed with soft grease and the box should be filled up to the correct level with gear oil. (See subsection 9.) On no account must heavy yellow grease be used."
My manual says 'Oil'. As for 'Recesses' - which I take to mean things like the bearings and gear change mechanism, although I just 'Fill with oil', as also stated. Carry on nit-picking if you must, and stuff your gearbox full of grease if it keeps you happy, it is no skin off my nose and I will continue using oil, as it states on the filler plugs of British machines and enjoy being able to use the filler, level and drain plugs for their intended purposes, thanks all the same.

Nice use of your swing press there.
If I put oil in my Indian trials bullet gearbox, I go out a week later to find it's peed half of it out past the bearing and final drive sprocket and onto the floor. Probably due to a combination of the lack of seal on the sprockets of the size I'm using and parking it canted over on the sidestand so the oil level is above the mainshaft level. So grease it is. Which in fairness, it what's specified in the owners manual. I'm running EP90 in my 612 bullet which has a bearing with one seal on the end of the mainshaft, it seems to be able to keep hold of the oil despite also being parked on the sidestand. The close ratio gears are a good modification though as long as you have enough power to pull first properly, makes third a viable road-speed gear to ride about in on the twisties without the engine screaming and snick 4th when cruising.
I presume it must be either an Indian manual, or some other more recent manual you refer to, as the Redditch manual states 'engine oil'.
@@paulhenshaw4514 The Indian user manual that came with the bike specifies 00 grade semi-fluid grease in the gearbox then top-up with 15w-40 oil.
I notice the famous quality street tub in the film
And the quality (street ) of them has gone down as well . Not as strong as they used to be .
What *is* this tub? I have little familiarity with Enfields - given that I’ve chiefly worked on Hondas, Yamahas and Kawasakis…
@@dennisyoung4631 Quality street is the brand name of a selection of sweets ( candy ) sold in a tub / barrel . Usually bought around Christmas time but available all year round .
@@anthonycarty9433 thanks. Was thinking it was a *gearbox part* of some kind!
@@dennisyoung4631 Forgot to mention that when all the sweets are eaten the tubs often get used for putting nuts and bolts from your engine rebuild in . They used to be made from metal , much sturdier .
Trying to keep up with you Paul🖕 totally hooked
Hi Paul, Is it possible to change the gearbox bearings in situ or does the box have to come out of the frame? I know that you have to warm the case up and bang the case on a block of wood to get the bearing to drop out but was wondering if it can be done with the box in the frame, somehow.
Yes, I have done so a number of times.
👌👌👌👍👍👍👍👌👌
The subject of grease came about from Royal Enfied workshop manual E1 PAGE 3 SECTION 5 REASSEMBLY OF GEARBOX in normal climates the recesses in in the gearbox should be packed with soft grease and the box filled with gear oil ,on no account must heavy yellow grease be used . this is quoted in for 350/500 bullets constellation etc , these workshop manuals can be viewed on Hitchcocks site information . INDIAN gear box used VEEDOL 00 grease toped up with SAE 50 oil . these are factory manuals hope this clears the subject .
The Redditch manual says OIL. I prefer to go by their manual, seeing as they designed and built the machines first!
