Stahlbus - oil drain valve

[linuxyeti]

Hi All

Just ordered one of these, I'll keep you updated on it's use, although, it could b a little while before I do, as, the next oil change will be as normal, so, I won't be able to judge it's use until the oil change after next.

Looks good though, and I have, once in the dim and distant past had a stripped thread on a drain plug.

Hi, yes a good idea, this type of connector works good with water and air, should be just as good with oil

I find it a bit too over engineered. How often do you normally change the oil anyway? Not talking about track bikes.

Hi

Well, I change the oil, on each of the 3 main bikes 3 or 4 times a year. I like it for all the reasons that are mentioned on the site.

Hunting round for the drain plug, after it's dropped in the tray, getting oil over my hands, but, I like the option to avoid the risk of threading the oil drain plug. I like the neatness of it. I did try a suction pump, but, apart from the enfield, I couldn't get all the oil out.

It may not be for everyone, but, for me, I think it's going to be ideal.

Looking at the desing, it will leak. Meaning, it won't last long.
When I change the oil, I wear rubber gloves and never had to ''hunt around for the drain plug''. The drain bolt and a copper washer is the best desing, in my humble opinion. If you're not torque perceptive enough, buy a torque wrench.

Why should it leak, this and similar designs are used in a variety of industrial uses. Each to there own, in well over 100 oil changes I've only ever had 1 stripped thread. Also, there is somone else on here suffering with a rounded drain plug bolt, again, this would alleviate the number of issues such as that, not all I wouldn't have thought, but a fair few of them.

Each to their own, but it's worth a punt on 1 bike, if it works well, then I'll get similar for my other bikes, if it doesn't work, I'll simply go back to using the original drain plug.

Looking at the spring loaded valve, I just can't see it lasting long. I mean, isn't the key for reliability to keep things as simple as possible with limited amount of moving parts?

Hmm, £40.
I've fitted a fumoto drain valve before, cost about £20, it made changing the oil on a Jeep much easier and without having to really get under the vehicle. I could just reach under with a pair of pliers, remove the lockring and turn the valve open. Oil changes were every 6k.
Not fitted one on the bike. Not convinced it was really worthwhile on the Jeep.

Hi

Yeah, did consider one of those, but though it a little too tempting for some scrote to open the valve all too easily !!

Probably not many, however, unlike a car oil drain plug which is pretty well hidden, a bike's oil drain plug, isn't usually quite so well hidden, offering up a little more temptation !!! Also, I think the Stahlbus valve just looks neater.

Keep us updated with this that seems a smart system. I don't think it would leak, and if there is a small leak it would get caught in the cap that's supplied (?)

I like the idea of connecting the tube to it, perhaps with a bit of practice, this could mean an oil change on my ZZR without having to remove belly pans etc. I wouldn't mind doing 2 oil changes per filter change for example. Also, it could be transferred between bikes, providing the screw is the same size, so it's not a "sunk" cost?

Hi

Will do. Yeah, if the thread size & pitch are the same, nothing to stop you putting it on another bike, when it comes time to replace the bike it's on. So, if you do get one, keep the original drain plug in a safe place

Harely Davidsons evo engines have an scavenge oil pump with a ball check valve that's closed when the engine is shut off. They are known to wet sump over a period of time if any dirt gets stuck in there or as the spring ages. I imagine over the long term that could do the same, ie let a drip of oil past, but it'll be of no consequence as you've got a cap with a rubber seal. Oil changes will still be easier as at most you'll only ever have a tiny cap full of oil to deal with. Then again, not all evo's wet sump, and that valve is made by ze Germans.
I like it, just not £40 worth.
