Busted aMOSa starter

Post by jaimenv » Sun Feb 17, 2019 8:27 am









Do this taiwanese starters fail like this often? or should I look for another cause to the failure.
Anyone out there want to part with a rebuildable OEM starter for a 1100. I sure has a few good parts from the failed one.

It's pretty common. They use cheap plastic or pot metal gears that can't handle the torque.

Many people take the head (containing the OEM planetary gear set) off their old, dead starter and graft it onto their new China starter in place of the plastic gear set that the China one comes with.

Yes it makes cense the way the gear end cracked and the gears turned to gravel.
Got a hold of the PO to see if he had the old starter, he said it is gone in to the garbage.
Guess my best bet is going to look for a refurbished one.
On the mean time I got the rear breaks to release the rear tire, the pressure drain port on the master cylinder was plugged.

Somebody may have a spare gearhead laying around...I'll look too.

Thanks I appreciate the effort.
Mean while I checked the timing belts and radiator for oil. Belts are stretched yet usable for testing for other problems, radiator is good no oil residue. Tomorrow I drain the oil and look for metal particles.
Did a hand job compression test (no starter) and found #2 way low and #4 little better, So I decided to check valve clearance on the offending cylinders they both had very tight no play exhaust valve clearances, figure might as well check and adjust all cylinders. Checked compression again and the offending cylinders came back to match the others, just awesome.

Timing belts do not stretch.

The length of the timing belt is critical to ensure the timing of the engine is correct. For this reason, they have lengthwise fibers inside them that do not stretch, at all, unlike traditional V-belts or serpentine belts. Even an aged timing belt does not stretch.

This is why timing belts that are old and in desperate need of replacement can still look good: they don't crack, because they don't stretch.

That said, if your belt IS showing cracks, that's a good indication that the fibers inside it are failing, and the belt itself is likely to fail in the near future. However, most timing belts give no indication of failure - one that is going to fail the next time you start the engine can look exactly the same as one that will run for another 20,000 miles.

Timing belts are cheap. You will be kicking yourself if one fails and you trash your engine. I'd suggest changing them before you try starting it up.

Advise taken.
I will replace the belts before I try to start the engine.
Thanks.

Well got me a replacement starter supposedly a used one hoping it would be OEM, so in the case it would not work I at least could use my spare parts from the busted one the bike came with.
Low and behold it is a refurbished Taiwanese one what look like new in the inside.
But the real kicker is the fact that the power connection is in the opposite side, so I will need to make me a longer power cable to reach the connection.
This is what happen when you wear beer goggles when ordering stuff :roll: .
I should have noted from the posted picture that the connector was on the other end and that the field magnets (?) screws where missing from the body. This means that the field magnets are glued to the body unlike the OEM that are screw/bolted in place. Also the starter uses 4 brushes instead of 2 as per OEM starters.

At any rate it spins in the correct direction and the bike started and ran till I smelled gas from #1 carb stuck float. So far happy camper.

PS I did change the timing belts ;) .

Looks like you didn't get a gl1100 starter with your beer goggles on ordering.

Looks like I did good after all when I got the used starter.
It turns out to be a Ricks Electrics aftermarket one.

It's been said the Permanent-Magnet starters have a little advantage over the standard starter, with the magnets you aren't using current to hot up the field, and 4 brushes means you have two armature windings hot instead of just one, could provide better torque.

Thanks for the info. I didn't know that.
It feels peppy when it turns the motor, yet I don't have much experience since I just started working on this bikes.
They are for sure a challenge to work on due to the size and weight, but never the less a mechanical wonder. I enjoy working on them a lot. 8-)
