Dr Bob, I've been watching your thread on the ST227P with interest, particularly the latter posts on lubrication of the gears. On looking at the owner's manual (115 68 34-27 Rev. 3), page 14 has this:


TRACTION DRIVE SYSTEM
DO NOT lubricate the drive components inside the snow
thrower. The sprockets, hex shafts, drive disc and friction
wheel require no lubrication. The bearings and bushings
are lifetime lubricated and require no maintenance.
CAUTION: Any lubricating of the above components
can cause contamination of the friction
wheel and damage to the drive system of your
snow thrower.


It would seem that your findings are contrary to what the manual says. I got mine in February 2018; would that have changed things vs your 2015 machine? Perhaps the mfg has learned from mistakes, improved quality control?


Another question: if I do get into checking lubrication of the planetary gear bearings, for ease of access is it ok to tilt the machine up onto the front of the bucket, or would I be asking for trouble by putting the engine 90 degrees out of horizontal and having fluids dribble out the wrong places?

Hi Dick --

I looked at the manual recommendations for no lubrication on drive pieces in the box, and then looked at the chewed up steering shaft and the fragments of roller bearing rollers that had locked up the planetary box. Their idea of "lifetime lubrication" for the bearings was the same as "none". Maybe their "lifetime" expectancy is a lot shorter than mine for these pieces. It was a tough decision (not...) to replace the bearings, pack them with heavy grease, and reassemble. I agree that you don't want anything to contaminate the friction disk and the rubber tire on the drive wheel, so of course you'll want to use some good sense and not add globs of grease where they will get thrown around on the drive disk. The dry needle bearings were inside the planetary reduction box, three in each one. There are no seals of any kind to keep grease in the bearings or housings so this will likely turn into an annual exercise at least for me. Meanwhile, looking at the parts sheet, the rubber tire for the friction drive is about $7, so a new one came this week (finally...) with the rest of the new and spare drive parts. I'll be getting into the project in the next few weeks, as soon as spring really launches and the machine is ready to be put away for the summer.

Maybe of interest: I dropped the drive box cover for a peeky after about 4 hours of use on the greased bearings. No traces of grease on anything except the cover itself and the case flanges it fastens to, all below the drive gears. Nothing anywhere near the friction disk or the tire. The difference in noise and smoothness is pretty impressive, by the way. Having the reduction boxes working is essential, while the telltale noise reduction is icing on the cake really.


Plan is to run the video cameras when I take the box apart this time. Hopefully someone will find it useful, and save themselves the annoyance of the bearing failure over less than an ounce of synthetic CV joint grease.

Carrying the "lifetime" theme a little further, the only lubricated and sealed bearings in the drive section are the two ball bearings that carry the steering shaft. You can see the bearings from the outside of the case on either side, above where the main wheel axles pass through the housing. These bearings were all but frozen up, so they were replaced with new as part of the band-aid session for the planetary units' dry needle bearings. Bearings were cheap (under $15/pr on Amazon with the needle bearings), so there's an extra set in the spares box for the time I find them even a little grumbly. They come off the shaft when the needle bearings get serviced, so easy to check and easy to just replace when needed.

Tempting the Snow Gods (!)

Tempting the snow gods, yesterday I took the opportunity to get started on end-of-season pre-storage prep. I drained the tank and the carburetor bowl, but put off the next parts of the protocol when I saw winter storm warnings go up for the Cascades an hour north of us. I was inspired by the main forums thread here https://www.snowblowerforum.com/foru...reakdowns.html where I listed all the stuff I do. It wan't a big list, but it's important. Draining the fuel is pretty easy, after you remove the small bolts that hold the carburetor and muffler covers. Total time less than 10 minutes, cheap insurance against corrosion and other fuel system problems related to keeping old ethanol-laced fuel in the engine all summer and fall. It's an easy first step on the way to off-season storage. I was told by mrs dr bob that there will be no more of this kind of activity for at least another few weeks.

Way Too Early, But Here We Go!

Forecast for this weekend has maybe 4" of snow mixed with rain between Saturday and early Monday. Kinda rude especially so early on the calendar. But it did inspire me to swap in the new "steering shaft" as promised last spring. I ran the video camera but have so say that my video skills absolutely suck. I spent 20 mins getting the machine up high enough on jack-stands to get good video up into the drive case. Then futzed around for another 20 mins doing a five-minute job. Bottom line is that the new shaft is in with new needle bearings and new grease, but no movie studio is going to be releasing my DIY wrench-umentary very soon.

In preparation for the blooozard forecast starting tomorrow, I celebrated with fresh fuel and stabilizer in the red cans. Re-sealed the painted metal bits including the augers and impellers. Looked hard at the impeller to find inspiration for drilling for the rubber "impeller kit" flaps. There's maybe 10mm of clearance between the arms and the barrel, something I'll cry about later when slush has filled the chute for the fourth time in as many minutes. Need to bring a couple snow shovels down out of storage and get them paint-sealed too. Now where did I put those gloves and the other winter gear? I'm sure it's around here somewhere... Hey, it's not even October yet, yet I expect to see the resident "first flake" out doing a snow dance tomorrow. Film at 11...

Our early 3-6" soggy-snow prediction fizzled. Nothing on the street or driveway, but the trees and lawn got enough to make it look like winter. In anticipation, I decided to put fuel in it and make sure everything is still good. It looks/sounds like the forward support for the exhaust shield has cracked at the exhaust port end. I looked at the Husky and LCT parts drawings, but this bracket doesn't have a listing or a part/diagram number. I may have to do a little fabrication to get a new/better bracket in place. The original one is captive by the retainer so this isn't fatal, giving me some time to get a new piece made. The original is very thin steel, and it's Swiss-cheesed to help it shed heat. I may do some hacksaw surgery on a couple fender washers, and pop-rivet new tabs onto the original metal. Else make a whole new one. Else everything starts-runs-drives as new.

Historically, first measurable snow happens no earlier than mid-November. There's a good case for draining the tank and carburetor again, with fuel into the sealed fuel can again. Jury is still out on the ATF and cylinder fogging.

In my pre-season false-start prep and run, I noticed a bit of engine cover rattling at isle speed. Turns out that the front support bracket for the muffler shield has cracked through right where it fits around the exhaust coupling where it bolts to the cylinder. The bracket falls into a parts limbo where it doesn't show as a separate part, or even as a part of the muffler heat shield assembly or the muffler itself. I'll likely end up fabricating a new one or at least a new bottom end I can attach to the exhaust studs. Hmmm.

Others are encouraged to take a look at that front bracket at the bottom end for similar cracking/failure.

Working in the shop today, I'm starting to get that itch. You know the one. The "toyz that make noiz" one. We need some more snow on the mountain for skiing please, and maybe some here in town too for good measure. Summer driver will get its winter storage prep soon, probably before Thanksgiving. Once that gets put away, the only outdoor fun thing left is winter toys. Jesdog is probably still playing golf up at Eagle Crest. Our little 9-hole is done for the winter, but Bend is still offering mid-morning golf if I get the WD's.

dr bob, yes we were golfing last week enjoying the last warm days of this fall. As accurately predicted snow came last night and continues today (November 28, 2019). I was able to fire up the ST227P with fresh gas/stabilizer in anticipation for this (too early)snow event and did our driveway in an hour. 4-5" of wet snow but the job is done for today. I helped my neighbor clear his driveway as he had an electric Sno Joe and he got most of it done before i was on scene. I had him clear a perimeter so I could finish without running over anything.
After lubricating the planetary gears and drive unit last spring following your excellent guidance, I noticed the reverse was not engaging normally and it was tempermental and mostly not engaging at all. When the cover of the drive train was off I noticed that the round wheel that engages the friction disc would move slowly on the horizontal shaft and then engage reverse. I thought it was a little too slow but after shifting several times, it worked fine after the spring tune up. Today, it was not engaging again and although the reverse is slow anyway by design, hefting it backwards was strenuous. Anyway, what are your thoughts. Hopefully, maybe a cable adjustment but I'll await your sage advice. Well, hopefully this storm passes through and the snow melts and on to golf again. When State transportation has to close the border between CA/OR you know the storm is/was a big one. Happy Thanksgiving to all.

Success thanks to YouTube. Now have Reverse and FWD drive speeds. Apparently, I failed to link the Trunion Bearing to the Bracket Yoke (connects to the friction disc assembly) which negated the reverse speed.

Here is the video on the 200 series drive train. I thought it was pretty good.

Anyway, my skill level still has its limitations and glad I came across the video. Should snow tonight so I'll give it a go in the am.
