OK, go ahead... but I don't think this contributes anything to anyone looking for help or an opinion about oil... But wouldn't it be better to visit them? I guarantee you that the adrenaline would be much much much higher... and you can even change the oil...:sneaky:

My friends, are you joking or off topic... An oil must not be used for marketing media, labels or personal prints. Oils are manufactured and classified by worldwide accreditation bodies and when stamped with a classification (SAE, API, ISO, ILSAC...), it is because they have fulfilled a...

Oops! My English is not very good, but I don't remember where I left the impression that I'm a fan of some type of oil... I passed on my knowledge about it, reinforcing that the best oil is the one indicated by the machine manufacturer, always. Tell me where I left that impression.

OK, there is a certain logic to this, especially if the oil indicated in the manufacturer's manual contains mineral and synthetic oils or if you use a synthetic oil on an older engine, even if it has similar viscosity. It turns out that synthetic oils are less viscous (compared to minerals), and...

Unfortunately, oil is not a question of love or hate, it is a technical question that even transcends empirical evaluations without its own instruments... and just like cigarettes, the inappropriate use of oil does not cause immediate harm, but shortens life useful or the performance of any...

Sorry, but there is a misconception here... Every oil undergoes a change in viscosity due to heat, that is, the higher the heat, the lower its viscosity... the graph below demonstrates this and more... Credits: https://www.kewengineering.co.uk/Auto_oils/oil_viscosity_explained.htm On the...

No...SAE is an old world society and with strong accreditation, 99.99% of oil manufacturers carry their certificate. The letter W (in the SAE specification) is indicative of oils for negative temperature ranges in °C, partial or total. I searched for 30W oils and I only found one from West...

Me too... it was just to reinforce the importance of the letter "W" in the SAE classification, but it doesn't mean that it didn't exist, doesn't exist or that it won't be created in the future... it's just a question of market or industry needs. For example: why have SAE 0W30, SAE 5W30, SAE...

I know you know, but if you ask at a store: SAE 30W - monoviscous oil for winter (cold weather) SAE 30 - normal monoviscous oil, positive temperatures (majority) SAE 30W30 - multi-viscous oil for winter and summer There are 3 oils with the same viscosity, but they work in different...

Well, the letter "W" in the SAE classification lends itself more to winter oils... could it be that you didn't want to say SAE 40?(without the W)

SAE 40W!!! If there is, it's winter oil... it'll fry at 100°F

I don't understand... what burns faster? Engine or oil?

Virgil_c I live a little far from the big lawn mower market (USA), where everything that is imported is very expensive or difficult to find. Things that are simple and even cheap for Americans, are complicated and expensive for Brazilians, leaving us with the creativity for various solutions...

Well ... I bought another automotive filter with the same thread as the previous one (M20), only a little bigger. This decision was not to further spoil what was started by the previous owner. I also opened the old filter to analyze more filings and get to know it from the inside. I washed...

In fact, there is little information about VST, where the manufacturer recommends a complete replacement, if the problem is not solved by the few tests indicated in the manual. The exact reason for this is unknown, but I can quote some such as the decision not to manufacture anymore, difficulty...

My friend, the oil specified by the manufacturer will always be the best oil, as he has tested and approved the use.

As a user, I would be afraid to use a lawn mower in such a situation ... and I would not buy one with a fiberglass deck without a good iron mesh inside. I say this because, for a brief period, I used a similar cutter and ran over stumps and stones that would most likely break a fiber deck or...

My level of knowledge in this equipment is very low, so some questions may seem naive, but I believe they are valid since most users are in fact ignorant and I believe that this forum exists to clarify doubts about defects, operation, exchange experiences as you and many others do so gently. Of...

Analyzing the oil ... Due to the lack of knowledge of a standard procedure (which can even be centrifuging and not magnetic), I adopted a very simple one that can be seen and understood by the photos and video below, remembering only that the oil was not at the working temperature and that the...

When you work on what you like, the result is always good, because the commitment is maximum, as well as the result.

Really, spending my time on the things I like is fun ... boring is not having the materials on hand and taking a while to get them, doing is another fun. Just as there was no magnetic plug in my car, after putting it on I was amazed at what was circulating and I imagine the harm it does ...

A small modification ... Nitrile rubber is expensive and would still have to be adapted ... but there is an almost inexhaustible and free source on the floor of car workshops. It is an O-ring of the fuel injector nozzles. Then... I tried to make an aluminum washer, it didn't look good ...

I am the owner of a lawn mower that can be driven for about 3 or 4 months, which in reality has not yet cut a lint of grass, because the machine I bought used was either very badly treated or I am very demanding. The fact is that I have seen a lot of material on the subject due to the needs of...

Nobody talked about PO?

You know something is good, but can it improve? So it is...

I totally agree ... but when the option is too far away or too expensive, there are other possible and fully acceptable options ... not for everything, of course!

Be careful with Murphy's law ...

Hey, guys... The washers arrived ahead of schedule ... Although the lock washer is not a very hard steel, it should last a long time and I now have several. Due to the thicknesses it was not possible to place the 3 (1 lock and 2 spacing, according to the drawing), the lock must spend first...

Evolution 2... Turned and ready parts. Connected parts. Note: soft washer is missing and exchange EVA rubber for another nitrile.

Evolution ... Turned and ready parts, lacking a nitrile rubber, a soft washer and a small chain to hold the lid. Preparation of the exagonal part. Internal turning with the same size as the connection pipe Detail of the internal channels for better sealing. Turning the sealing pin to the...

muddy 51 Yes, friends have already passed on this information ... but I imagined that the taper (angle) was on the male thread (plug) but after placing the test plug I saw that the angle is on the female thread (engine). But when passing the improvised tool, the NPT thread was changed to a...

Jagger2002 My "suggestion" is that due to the fact that you did not fill the filter before, it accumulated air and the oil did not enter it, that is, the extra volume that you are seeing on the dipstick is what did not enter the filter. I don't know why you lost the oil ... didn't you rescue...

Continuation... Yesterday I researched the market and found 3 stores and only 1 accepted to sell me, a piece as said by Scrubcadet10, if it were in iron it would be quite cheap, but I prefer in aluminum or brass, I found what is called here "long nipple" , in brass, whose value is BRL 55.00 (+...

An analogy with the auto industry ... In my country, I participate in a Chevrolet brand forum, the most frequent question being about replacing it with synthetic oil, thinner or thicker. Some automakers only recommend the oil itself (as if they made it), but most recommend 1 or 2 types of SAE...

I also think that any change is based on external needs, but there are hobbyists, people who have to do something unprecedented or very difficult ... a self challenge. There are also those who do it for the sake of exhibitionism ... I think that's where the crazy contests start. I saw videos...

bertsmobile1 kkkk ... me too ... Anzac Day is an Australian celebration ... do you live in Australia or in an Australian community? Lawn mowers is a completely new subject for me and here there are no groups for discussion and to know more is to make less mistakes. As I thought, this...

Nobody answered...?

Scrubcadet10 The world here is another one of my friends ... 3/8 is not standard for ordinary people, just for industry and nobody sells a 10 or 15cm piece, only 3 or 6 meter sticks. In addition to conical threads here it is only for materials under pressure (gases or fluids), minus the public...

Okay, being NPT, I already saw that the thread tooth angle is 60 ° and the taper can be 2 °. But I also saw that every NPT / BSP female is parallel, so the male can be at standard NPT angle (1 ° 45 ' to 2 °) or parallel. I believe that the fact that bertsmobile1 uses both NPT and BSP in "taps...

I understand ... but I waste time or money looking for a representative ... the best thing is to do it. But do you say that the thread is tapered (not parallel)? This complicates a little without knowing the angle. Do you know the standard (BSP, NPT)?

There's something different ... The hole in the housing is 9/16 = 0.563 " The tube as quoted from 3/8 = 0.375 " Did they widen the casing hole? The thread of the water valve is quite different and what was sealed was the excess of teflon tape.

Hey guys! As some already know, I am repairing a Murray 42" with B&S 31P777 and one of the problems is the oil plug that came with a water valve (don't laugh). I need to know the measures of such a plug to make an appropriate one, because here it is either very expensive or it is very difficult...

Well, the solution for the washers ended up being national, since neither the official seller returned my request for a quote (made within 1 week) and I will also not import via Amazon or e-Bay. I found the washers in the exact diameters, with a small difference in thickness ... at (29) with...

Well, as I said before, I drilled the hole and put 1 liter of kerosene ... I swung in several positions until I was tired ... something like sand (!?!) came out, small pieces of joint and very fine iron filings of used gearboxes. Even when swinging and rotating the axles with kerosene, no part...

Although I managed to drain the oil through the hole in the ball, drilling the box could be an option, but the amount of oil that came out, after 2 days with various inclinations, was half of what it should be (like in a car, standing up) 5% must be normal), indicating that: 1 - or leaked...

Good news!!! 1 - Carlisle answered me which tube is ideal for my tire ... Carlisle 320410 Tube 18 X 6.50 / 8.50 / 9.50-8, confirming what was said by the Lefort team ... excellent! 2 - After sanding, experimenting, sanding, experimenting ... I reached a maximum thickness value, to fix the...

Yesterday I got in touch with the Lefort representative, who called me today saying that the inner tube fits my tire. The justification was that the camera meets a range of measures, including my tire ...

With a few hours of searching and working, I managed to make the tablets exactly ... but ... Either the inserts do not have the same thickness (internal / external) or there is some difference in my system, because the external support does not touch the transmission box, there is still...

This is my strategy ... without a "B" plan .?

Rivets, See how difficult things are here ... I just received the quote for brake pads from the only existing supplier. BRL326.00, which is equivalent to USD62.69 in a simple and direct conversion. In this difference (USD 8 to USD62) are fees and profit from the supplier, of course, but it is...
