I grease my idler bearing periodically, with high molybdenum concentration grease. I use a hypodermic needle, modified with a grease nipple, to get past the seals - you can purchase the same idea on line. 😈

Friend Hammermechanicman, " Your statement, above, is substantially correct I am old enough to remember when detergents in engine oil were only used in diesel engines. In fact we were warned against detergent oils for petrols - dire consequences would result etc etc.. Then came the advice - if...

It may be time to remove/dismantle the carburettor. Clean with carburettor cleaner & compressed air. Make sure all jets/aperture's are open/free from gum. Reassemble/fit and try again. 😈

Sounds like old fuel has gummed up the carburettor. Remove carb. , dismantle, clean thouroughly with carby clean & compressed air. Check ALL jets/apertures are free from gum. Reassemble/fit & try again. Really suborn gum can often be dislodged by rodding with copper wire. 😈

Mulch kits = marketing gimmick that uses more hp/fuel to do the same job as the standard/blade deck. 😈

An engine that must be started with " Starter Fluid Aerosol" has a problem that needs to be sorted out. You risk further damage with the habitual use of a starter aerosol (mostly ether). 😈

Guys Guys - Beware the marketing department. All you hear/read is not necessarily as portrayed - a healthy dose of scepticism will go a long way.

I am told that synthetic oils perform better, under hot conditions (eg air cooled engines), than straight mineral oils. An oil filter will do absolutely nothing to improve the performance of an oil. The filters job is to remove contaminants - mainly metal. Consider; I have used straight 30W...

These sort of fuel gauges/sensors are, for the most part, unreliable. Yous your eyeball or a calibrated pace of dowel/dip stick 😈

You should have told him that sharpening the blades has no significant benefit, other than to the blade supplier 😈

Why? What is your rational for the above opinion? 😈

The only significant "impurities" the crankcase oil may collect is water vapour. The next time you use the machine AND it gets to its loaded (working) running temperature, for at least 30 minutes, the water vapour will be driven off. I live in Australia (opposite seasons to you). I have...

Thats very interesting. The B&S Yellow oil filters PN 696854 is 28 micron with 96 sq/in of media. This is twice the media surface area, of the same external sized Short Black 492932. Yes more pleats could squeeze in more media but twice as much, sounds a little far-fetched. The Yellow filters...

What is the knowledge base that informs your statement? 😈

You suggest that the filter media will catch finer particle (smaller micron). If this be correct then its likly the filter will; Compared with say the Long Black, raise oil pressure, by restricting oil flow Block sooner (shorter service life) & further raise oil pressure, by catching more...

SOOOoooooo! The consensuses would seem to be that the B&S Yellow & Orange oil filters are a marketing gimmick😈

"Extended oil filter life" Not oil filter life. B&S are claiming an extended oil service interval from 50 -100hr oil change, with yellow & orange oil filters. 😈

Sorry ILENGINE , I don't see how your comments give me understanding of why B&S recomend three diffrent (?) oil filters for the same engine. Are you sort of saying its a marketing gimmick and there is no functional difference between the three filters? 😈

The Yellow is what I have order - same as fitted when new. The Orange has the same descriptor "High Efficiency...." as Yellow. The Maintenance Schedule; Black filter - oil & filter replace 50 hrs Yellow & Orange filter - oil & filter replace 100 hrs So no benefit, real or imagined with the...

Thanks MParr - this is a customers near new engine, in a not so new chassis (origional B&S dropped a con rod). With customers that have near new equipment, I tend to fit OM parts (B&S/Ferris in this case). Still waiting on an informed answer as to why B&S specify no less than 3 oil filters...

Thanks Auto Doc's, "...slightly better filtering media..." In general engine filters are judged on their ability to remove contaminants, down to a certain size (micron), while not unduly restricting flow (surface area) For the most part filters remove solids ie products (metal) of...

Hi, Servicing a Ferris 400s with B&S 440000 engine. Manual shows three suitable oil filters; Standard Black PN 492932S High Efficiency Yellow PN96854 High Efficiency Orange PN796576 The last two have extended oil change intervals. Is this a marketing gimmick?? Anyone know what is the real...

You could just work out fuel used per hour of operation. Time elapse, from start, will then give you a fairly accurate fuel used/remaining. Simple! he only failure point is the operators inattention. 😈

If I put Toro Fan PN 104-2162 into Google, I get Hydro Gear PN 50848 7" 10 blade fan . Will this fit/do the job?😈

Great information - my thanks 😈

If it makes any difference "Tractor Data" come up with two diffrent transaxles; Hydro Gear 321-0650 & 318-0510 Anyone know for sure. I forgot to add - this is a 17.44 HXL unit 😈

Hi, Old Toro Wheel horse, 14 hp, Model No 71283, Serial No 240000104? Does anyone know the make & model of the gearbox (GB), recommended oil & quantity. The mower is going well, however there is a very slow leak from the GB & today there seemed to be an unusual noise from that direction. I...

Kubota?

If you are serious about safety and capability on slopes, 4x4 is the only way to go. Here are a few Australian web site suggestions ( am sure most can be found in the USA): https://www.asmotor.com.au/ https://www.therazorback.com.au/...

Manufactures see oil change intervals as part of their marketing "spiel". They think (correctly?) that customers will be attracted by longer service intervals, lower cost(?). That such long intervals (300hrs) may end with higher maintenance/repair cost does not concern them - the engine now...

No matter what the manufacturer recommends, shorter oil change intervals, are better than long. This is especially true for the first oil change in a new engine. Assembly contamination (swarf, etc) does happen and can easily damage a new engine - for the modest cost of fresh oil/filter, its a no...

"Have you done as I asked? Lay your used filter 1/3rd full on its side and observe oil leaking out or not? It will leak slowly through the anti-drainback valve." Sorry Grumpy Cat - next servicing/oil change, probably several weeks away "Which is most appropriately an anti-backwash valve."...

Hi Grumpy Cat, Strikes me that efficacy of non return valve will depend on; Quality of filter Column of oil above/below filter, providing additional sealing pressure (absent when you remove filter & allow to drain on side) "Subaru Outback 2.5i filter is mounted open end down, with an...

Never done an Australian survey - My subjective observation - Lawn mulching is rarely done, even collecting (harvesting) clippings not so common. Why? Simple - the clippings on the surface will be quickly consumed/processed by the organisms (worms/beetles/fungi /etc) living within the sward...

News to me!!! - For the last 50 years plus, I have understood the "drain back" prevention valve is so that oil will be available immediately at start up ie not drain back into the sump. This is specifically to reduce the accelerated wear, that would otherwise occur, due to the delay in oil...

What is it with us humans? - We almost always prefer the costly $$$ solution to the cheap. Why purchase this single use item, in a glossy package, when you can get a small role of ductile aluminium flashing (probably for less $) that will do the job just as well & can be used for a host of...

"Metal was a material I tried, but found that it would not hold its form" Obviously you did not try aluminium flashing. Its designed to be easily formed by hand, no tools or heating required ( similar to the lead flashing it replaces) and hold its form 😈

All way too complicated - I use a piece of malleable aluminium flashing (replaced lead). Can be purchased from the hardware in a small role. Its thin enough to cut with scissors (best with metal shears/snips), soft enough to be easily fashioned into a trough, that will hold its shape. Can be...

Just being pedantic; Weight is but one factor in blade balance. The other factors are "tracking" & weight distribution (base to tip). Tracking means, are all the blase following exactly the same path? This could be effected by damage, blade security, etc Weight distribution - A blade can weigh...

Sir! You are both a gentleman & a scholar - you flatter me. "Is this because the Cub has three mowing blades, and the John Deere has just two? What do you think?" Speculation: Depends on what you mean by blades. Two cutting heads will have 4 blades (even if its a single part, each blade has...

Hi TMT, "Hold on a second there, Skippy! There are those of us in society who are not content to just settle for the basic explanations of life. Many want to know the mechanics of how things work, why a blade cuts, etc. I confess that I am one of those people!! I enjoy a challenge and an...

I check rpm, on a verity of engines, single to four cylinder, about once per annum. To reduce error, I usually use a couple of photo types and a wire in/spark plug lead digital tacho. If the machine also has its own tacho, I end up with up to four comparisons (usually just two) - go with the...

They are far from precision tools. If cheap enough, purchase two & compare the reading. 😈

Sorry Stevestd - no idea how Took MakerTims name got attached to your words You only have to worry about blade balance, when you damage the blade OR sharpen it. Can only try and avoid damage - S--t happens! Sharpening is a deliberate choice, that you impose on yourself, for little gain &...

Agreed! :devilish:

Is the float valve rubber/Viton in good condition? I there any fuel "varnish" , other crap, on valve tip/valve seat? 😈

What can I say? - Mechanical aptitude/knowhow used to be common - no longer.

Or a "Mr Funnel " combination funnel & filter that will also remove any free water in the fuel. Mr Funnel comes in various sizes. For the penny pinchers ; You can make any funnel into a filter funnel by using filter fabric or very fine brass gauze (hard to find these days). The fabric or gauze...

I almost never wash my mowers/decks. I use high pressure air to remove chaff (wet & dry). Why? Simple, wet vegetative matter starts to ferment/break down almost as soon as it has been cut. In this process it develops a highly corrosive liquid. The liquid will vigorously attack/corrode all...

I agree that all fuel is potentially contaminated ("dirty" is a bit of an over statement). Carburetted systems are able to tolerate significant particle size ie as long as particles are smaller than smallest jet aperture, they will pass through. This is why you should take advise from...
