1200gs final drive

[Steptoe]

More like accountants intervening

Says someone who's opinion is worth listening to

 

[Ribcracker]

Deffinately a Market for someone to come up with a recondition/replacement option for the final drive.

 

[haydw]

Now we have established that there is a market, tooling is possible, parts available etc can someone get on and actually offer the service........ want to get my 1200ADV back on the road without having to sell a kidney on the black market.

 

[Demongroover]

I have been talking to Mick & Roy of RGM who seem well up for taking on this work. My FD will be posted tomorrow.

 

[mikeyboy]

what was the outcome demongroover???

 

[Rasher]

Cray engineering have done a few and I am sure they said they are considering doing them as a refurb service, may be worth calling them.

I am sure he said main issue was crap bearings, and regular (every service) oil changes may help.

 

[Kremmen]

The main crown wheel bearing is a sealed unit, so isn't lubricated by the FD oil
As for the bearings, these I'm reliably informed are manufactured in China from recycled bean cans sent over from the U.K.....nuff said.

I was told Poland from recycled Lada's

His FD is/was shot to pieces.

Indeed it was
Secondhand unit being sourced from Motorworks limited stock, Roy at RGM is fitting the disc & carrier and posting it back to me.

Bike is for sale now, on the relevant section on this forum.
Apart from this recent failure it's been ace, many farkles added. A bargain I reckon.

Nope. The big double ball/roller bearing that supports the pinion shaft, which along with the needle roller, are the ones that have failed in the GS's I've owned are made by INA in der Fatherland. At least that's what it's got stamped on them. I tried sourcing the big ones from a bearing supplier but of course it's a special made for BMW.

Not unless they've changed the design dramatically since I last peered inside one. Bearing is lubricated and cooled by the oil reservoir.

The worn examples I have in the garage are from Germany.

The problem IMHO is caused by the beancounters. Mercedes had a similar problem with the electrics in their cars (also had other problems, but thats a different discussion). The beancounters decided that they could save the equivelent of about 1p on the electrical connector terminals by sourcing a cheaper component.
Doesn't sound a great deal on the face of it, but when you work out how many connectors there are on every car, then multiply that by the number of models in the range, then look at how many vehicles they sell worldwide, it starts to add up. It took Mercedes about 10 years, plus millions in warranty claims and thousands of unhappy customers before they decided to correct their error (which they did in 2005). So my guess is we are in for a long battle with BMW.

Same old story

Marketeers took a load of life boats of the Titanic because they looked shite, then lowered the baulk heads that made it "unsinkable" to get a grander staircase in.

Then the Bean Counters fitted cheaper rivetts than the ones the designer specified, the rest as they say is History, which we never seem to learn from.

 

[BBB61]

I was under the impression that the reason they reduced the number of lifeboats on the Titanic was because of the successful use of radio in the rescue of 1500 passengers and crew when the Florida and the Republic collided in the Baltic Sea in January 1909. Having seen the success of that it was decided they didn't need as many lifeboats on the Titanic because they felt that help could be summonsed via radio very quickly.

I know this might sound a bit strange, but could the problem with the final drives relate to the bending stresses that are induced through the unit because of the single sided swingarm arrangement on the GS (and othe BM's)?

Your getting pretty close there. I've had a final drive leak for the last 12k, that's about 5 months.
Last time I serviced I put gen BMW oil in and a genuine seal, and the 'new' recommended 180ml oil.
Test result after 10 days riding.
1000 miles Nottingham to Malmo , Sweden;- no leak
100miles around town working in Malmo;- leaking and dripping on to tyre.
600 miles Malmo to Frankfurt-. no leaks.
900 miles Frankfurt to Nottingham (11 hours!);- no leaks
300 miles Nottingham to Cornwall ;- no leaks
50 miles around Launceston;- leaking and dripping on to tyre.
300 miles Cornwall to Nottingham;- no leaks.
No play on the rear wheel, no graunching etc. Must be some side play though, just enough to let the seal weep around town, but the motorway stuff is relatively upright.
Just observations,
Ride safe

Nothing to do with a F*%$!ing great Iceburg then?

Having seen the success of that it was decided they didn't need as many lifeboats on the Titanic because they felt that help could be summonsed via radio very quickly.

Some I believe used this as a defence, the law was made long before boats were so large, the original design had 3 times the number of lifeboats but the owners thought it spoiled the look, post Titanic the lawt changed to enough life boats for all passengers and crew.

The better rivetts would have probably withstood the damage far better and prevented the sinking, higher baulkheads may have also stopped as many compartments from flooding.

Certainly it would have stayed afloat longer.

Then again if the lookout had binoculars he may have seen it sooner, but that was down to poor (or no) Standard Operating Procedures, not withstanding the Captain ignoring Ice Warnings etc.

Most true disasters are a series of failures, but normally the blame gets pinned on an individual, so lets blame the chap that ordered the FD bearings!

So to put this back on thread.

If you buy a GS you have to install a life boat, or at least wear a life jackets.
