Here we have a fucked up input shaft on an M94 1995 R1100r.
Not sure what I should do about this to start with.


Clutch.



R1100r, 1995.
It is not a GS !, therefore not worth a great deal of money.
A mintier than mint one would possibly make £1600 - £1800 private sale.
So I would guess this bike would sell at maybe £900 - £1100.

However ! This machine is here to provide me with reliable commuting too and from work at any given moment day or night.
I obviously have backup bikes for this, to be used when one or it fails.(it did fail )

So it's value to me is slightly higher than the used bike market would suggest.

As you can all see from the photo's it is an early M94 gearbox and unfortunately it has the possibly troublesome taper roller bearings on the input shaft.

Speak to Steve Scriminger. My GS box was toast and he rebuilt it with all new bearings and an M97 cluster for £350! I've got a good s/h clutch if you need one.

Thanks for the clutch offer but I have a new one waiting to go in once I've done the gearbox.
New gearbox seals and bearings are on order from BMW and I spoke with scrimingers who are supplying me with the input shaft.
Once everything arrives I'll regrind the drive dogs if needed and rebuild it.
Jobs a good un. :thumb2
 
The nice helpful people known as Scriminger, sent me a second hand input shaft.
It has arrived.



Absolutely mint condition.
Thank you Scriminger's :thumb

Your not wrong.

It is a thing of beauty.
The wife tannoyed me from the house, to the bottom of the garden in my workshop notifying me of a parcel arriving .
Some time around 09:20, I had been in the workshop since 04:15 due to not sleeping very well since the last time of being away doing work stuff.
Anyhow, I wandered up to the house feeling the cold damp air running through my dressing gown, I was thinking how lucky I was being able to observe the beautiful early morning mist laying over the rear lawns, only three birds twittering on this occasion.
Earlier that morning whilst making my way down to the workshop in near darkness I had stopped part way across the lawns to observe the local owl shredding a small vole on the old tree stump.
The old tree stump had in recent years become a favourite place of the owl to prepare breakfast, lunch, dinner and supper.

By the time I had reached the workshop after watching the owl for a little while, maybe ten or fifteen minutes,
I suddenly became aware just how chilly I had become.
Somehow and for no reason, my mind had drifted onto the previous evening, there were seven of us. Not couples, but people with similar interests.
I had been chatting for some time with an enchantingly robust, naturally gorgeous unasuming young lady, who was totally unaware just how provocative her natural beauty was.
You could feel her innocence from her deep blue eyes and although her body was well covered, the rhythmic rise and fall of her ample yet not excessive bosom was enough to keep me intrigued and transfixed all evening.
By this time, day dreaming just outside of the workshop I again realised just how cold my knob and bollox were.
I also realised just how excited I had become, standing there on the lawn with my dressing gown forced open due to the excitement.

09:25.
Walking back to the workshop, slowly unwrapping the parcel, the first visible part of the input shaft was gleaming in the early morning sunshine.
I just could not believe the item in the parcel was second hand.
 
Now the excesses of the weekend are just a distant memory, I set about investigating the new second hand input shaft.
Removing the old bearings was required.



I've had the bearing/gear remover for a number of years and this time it had taken a little while to remember where I'd left the bugger.
Whilst looking for it, I had started to wonder what sex the owl was that uses my old tree stump as a food prep table.
A number of thoughts had crossed my mind during this time.
One of them was the possibility of sneaking up or laying in wait for the owl and grabbing it,
then turning it over and having a little looksee at it's undercarriage to try and find if it had an inny or an outy.
This idea soon passed.
The thought of wrestling with an owl might be construed as wildfowl interference, whatever sex it maybe, it's a big one and my curiosity might get me injured or even worse. Arrested !

Anyhow as expected, the bearings (one end has a circlip ) gave only a little resistance to being removed.



During the course of the morning I had many thoughts on sexing the owl, most of these were either impractical or just down right dangerous to both me and the owl.
I think I'll just take a photo and post it on the owl forum, if there is an owl forum that is.
Maybe I could start one ? Or maybe one is already there ?
I really don't know.

A little bit of red rust was visible on the new input shaft, on closer inspection though it turned out to be slight surface rust on the inside of one of the components.
No major worry, it soon cleaned up nice and shiny.

Inspection of the old gear clusters showed no major wear and tear, just normal contact marks. . . . .

 
With almost certainty, I now believe my owl is a male owl.
Owls partner up for life, much like swan's.
The female will stay on the nest and the male will go out hunting for food.
 
It's time I removed the old taper roller outer raceways from the gearbox cases.
Without the right tools, this can be difficult and could even damage the gearbox housings.
Be very careful doing this.
For removal we have a number of options.

Internal bearing puller.
Laser cutting.
Weld it out.
Cut with mini grinder ( Dremel )



I'm going to use a combination of two methods.
1, Weld it out.
2, Grind it out.

Welding it out is the quickest way but you need a welder.
Many years ago before my wife bought me a welder for our anniversary, I remember taking an aluminium casing with a taper bearing fitted in it to a local car repair place, you know like any back street independent.
I waved a 20.00 pound note at them and they happily put a run of weld round it.
I'm now good friends with that garage, i send the wife's car there.

Remember it's not what you know, it's who you know.
 
I'll have to come back to this thread in a little while.
The house maid has that knowing look in her eye, once she's finished pegging the washing out It'll be Jack and Danny time. . . .
 
What a timely thread.
I think you where thinking of different shiny shafts in the cold air.

Just heat the g'box casing up around the bearing housing until its Fukken hot , then turn the box over and slam it onto a wooden breadboard or similar a few times till it drops out.

If it works..let me know..:thumb2
 
I eventually got back to doing the gearbox after many, many interruptions.

I prepared the casings and bearings for welding, I used an old wet T shirt to protect everything not being welded.



The earlier escapade with the maid didn't go quite as I had envisioned,
I had been watching the maid trough the workshop window as she was bending down each time to get the next item of frillyness to peg out.
At one point, with a wry smile she moved around to face away from me whilst retrieving the washing each time from the basket on the floor.
When she had eventually finished she beckoned me over, this was it ! Were in !


In that time I had put some weld on the bearings, turned the cases over and as they cooled the bearings fell out un-aided.



When I had rushed out the workshop with my dressing gown blowing wide open in the breeze,
all she actually wanted was some money.
She was going out for lunch with her brother and offered to collect my prescription whilst out,
she knows like clockwork what day is prescription day and makes sure i take the pills every evening and every morning.
I'm trusted to take the lunchtime pills all by myself.



The vicar called in at one point just before lunch, we chatted on the lawn in the lovely sunshine, I had an ice cold fruity cider, the particular one evades my memory at the moment and the vicar being a man of the cloth had two gin and tonic's.
I told him about the owl, the maid and the gearbox.

Here it is done by the way.



The vicar explained in no uncertain terms that I ought to steer well clear of the owl, especially after what happened the last time with the cat from next door.
Didn't mention the maid though.
 
What a shame. When I first skim read and saw wet tee shirt and maid I had a very different set of photos in mind.
Ah well never mind I suppose the vicar wouldn't have been that keen.
