Challenging Wheel Bearing Replacement on a Sinnis Apache Motorbike

[@matthewharmer1656]

Quick tip, carry a small inverter welder weld a thick washer onto the bearing,punch through with a long drift after heating the hub first .ive done loads like this,also if your left with just the outer shell of a bearing a couple of blobs if weld gives you something to chiesel on.

Well done Steve, this one looked like a mammoth task!!

[@projectclark123]

I love doing wheel bearings

[@willswheels283]

Good job Steve, I had a similar issue a few years ago with a 1980 Honda CB250rs, so I had a good idea how much of a pig of a job that was.

[@cabbage681]

The slack chain is usually a good sign no maintenance or checks have been carried out by the owner and there will be trouble ahead. Good job of getting that bearing out without damaging the wheel or throwing it over the fence in frustration👍

[@themobilemotorbikemechanic]

It tried my patience but we managed to sort it out

[@FREE_PUREBLOOD333]

Omg...that thin rear disc banging on the tarmac !! Come on man.

[@themobilemotorbikemechanic]

Nope. Look again and you’ll see blocks of wood supporting the wheel rim

[@tommoso55]

Well done that man 😄👍👍👍

Feel you're pain, had a "mare" doing fork seals this week, 1st one went great, second couldn't separate the tubes, fork seal from hell... ... ...

[@themobilemotorbikemechanic]

Sorry to hear that. Been there 😏

[@hlpang1075]

How do you keep all the right parts in your van?

[@themobilemotorbikemechanic]

We don’t. We only keep the relevant parts for the jobs we are going to.

[@Cronus111]

Are you accounting for slightly more slack as you're adjusting the chain with the rear wheel off the ground or should that make no difference?

[@themobilemotorbikemechanic]

Yes which is why we adjust to around 25-30mm of play on this bike.

[@katywalker8322]

Weight of the bike is on the swinging arm (from the paddock stand), so it will compress the suspension pretty much the same amount.

[@timothywhieldon1971]

Fairly easy job make very difficult by not having the right tools.

[@themobilemotorbikemechanic]

What tools would you have used?

[@Jestersson]

Bearings are quite easy on some bikes I’ve changed a few and I’m not a trained mechanic but when their seized it makes it very difficult to remove without damaging the hub. I’m interested to know how you’d do it too🤷‍♂️

[@timothywhieldon1971]

@@themobilemotorbikemechanic #1 Instead of trying to pull the bearing out, drive it out from the other side with a drift and a hammer, the energy you are imparting on the system by trying to PULL the bearing out is not even CLOSE to 1/4 the force by going the other way. #2 a dewar of liquid nitrogen or a bag of dry ice is CHEAP and shrinks the bearing to drive them in with a simple aluminum drive set and a hammer similar but better than the amazon kits you used here. #3 a work bench or even a moving blanket so im not on my knees or at least not on the ground like that. #4, some grease, you put those seals in dry and never filled them with grease so that's a BIG fail #5 some sandpaper to CLEAN that trash out of the hub before driving in the bearings. #6 a proper torque wrench and a tape measure or calipers to set the back axle correctly and the nut to a proper torque. #7 (optional) a garage with good tools, not that amazon harbor fright trash that made your job a LOT harder #8 a shop manual.

[@timothywhieldon1971]

@@Jestersson I just answered that in a comment here. but TLDR: better tools, better methods, and a torque wrench

[@Jestersson]

@@timothywhieldon1971 You sound like a master mechanic. I’m sure Steve will take all that knowledge on board.

[@robbie2awesome]

I did my CBT on one of those, it was a piece of junk!

[@adriancallen2890]

SOMETHING AS SIMPLE AS REMOVAL OF A WHEEL BEARING CAN SOMETIMES TAKE HOURS OF WORK AS YOU PROVED, HOPE CUSTOMER APPRECIATES YOUR WORK AND TIME, ON SIDE OF ROAD ALSO, HELMETS OFF TO YOU, LOL.

[@chr11sf]

👍

[@leavemyrightsalone]

"Wheel bearing, yeah no problem" 😱😮☹😭😧😫😤

[@themobilemotorbikemechanic]

It’s the little jobs that can often become the most challenging

[@apacherider7110]

You have your torch too close to the hub, the yellow tip of the flame is the hotest, blue part is the coolest. Sorry to poke my noise in.
