Shaft Drive Shafted!!

[tkent02]

I am curious. I see no specs for secondary drive oil on the GS650GLD. Is my bike different to the 1000GL in this respect? When I was loosing oil out of the Secondary drive seal, It was engine oil coming out of the transmission. Or, am I wrong and I should be looking for an independent secondary drive oil deposit? I looked all over the service manual already. thanks

Yes, the 650s use their engine oil for the secondary drive. The 850 and bigger use real gear oil in a self contained secondary unit.

thanks for the response tkent. One less worry for me. I had ridden the bike about 2500 miles since the repair and got worried by this thread...

Hi Mr. Drbarson,

You'll find lots of shafty lovin' on my little website (remember your "mega-welcome"?). There are articles about changing the gear oil (sometimes called bezel gears, or secondary gears) and final drive unit oil. There is also a seal at the back of the gearbox where it meets the drive shaft that has been known to fail occasionally. You can remove the boot and inspect. Keep us informed.


Thank you for your indulgence,

ok.. previous owner says at no stage has he topped up the oil.
looking underneath with head light shows a inch long crack through the drive shaft boot, this is where the oil is comming from, (large amounts)
question is,does the oil that i put into the final gear case/hub, lubricate up near the drive shaft boot area..?
this is starting to sound like what dogma was saying.....??????

The drive shaft rides inside a tube that is part of the swing arm but it's not in an oil-sealed environment. The boot at the front of the shaft is covering a U-joint. That's all. Oil from the final drive does NOT go up the drive shaft to that boot. It should be sealed back at the hub/final drive assembly. That's where the drive shaft is attached with three bolts to the final drive.

update!
thanks again everybody so far,
turns out that my bike at one stage has had a 850 hub put on it.
also the oil comming from the rubber boot is actually comming from the rubber boot, turns out the hub has blown its seals and oils is running down the tube and out of the boot.
That red oil i originally spoke of was actually grease, turns out someone took the rear wheel off and coated the inside of the hub with grease and as the temps got hot it flung it out all over the wheel... He said this could of been done to mask a orignal oil leak from this area as the grease acts like a seal and soaks up some of the oil.

He qoated me 500$ for a seal kit or, 300$ for a 1100g hub he has in stock ( second hand and ausi prices) so i went for the hub.
stay tuned!!

You could buy a rear differential here in the states and have it posted to you for a 'whole lot' less than $300 AUD!

a used third member (hub as you say??) shouldn't be more than $25~50. then guessing another $50 to ship it

Hi,

I bought a spare final drive unit for my 850 for $25 off of ebay. You might want to shop around a bit.
