VS1400 drive fitting soon

After several hours over the last few days sanding and polishing my VS1400 drive it's finally done.
I'm taking my stock drive and spacer to be machined in a few days and need to fit the new seals.It should be finished next week.

When the drive arrived it was damaged so I'm pleased with the job I've done on it.

The damage to the drive case.



After sanding.



Finished. All nice and shiny.

Looking good Rattler. Looks like new.  

Enlighten me. Why are you fitting a 1400 drive please?

You are going to fall in love all over again Rattler, glad you are finally getting it done.   

Changes the gearing and they are also longer gears, really wakes the bike up.
Read (THIS) in the Modifications done section.

Looking good Rattler  

Good job done.  

looking nice and shiny 

Ok I'm confused. I started removing what I think is the seal expecting to find the circlip. Where is it?
This seal seams to be tucked in and is a right pain to get off.

That's the 800 seal, It's rubber coated metal, where the metal changes colour is the joint of the seal, grip it with some grips and twist and the joint will open up, then prise it off with a large flat screwdriver or similar and it will pull up and away from the shaft and housing, The Circlip is behind that,  don't worry about fucking the seal up, it's already knackered, when your replacing the 1400 seal, It's more like a fork seal that fits within the hole as opposed to over it.

Lol so I've just removed the rubber coating. I'll do that tomorrow night.

Is this good enough to give to the guy milling it.

That'll be fine Rattler  

Any tips on removing this seal to get to the circlip on the 800 drive? Can't budge the damn thing. Tried loosening it with grips.

I just used a hammer and screwdriver    It isn't being re fitted, so I just tapped the edge till a gap appeared then prized it gently off with a screwdriver working my way round it till it was removable by hand.

Done it bud after a long while. Can't get the bloody circlip off though. It snapped my circlip pliers.

I was trying to open the circlip not close it. Should have realised by Dave saying he used needle nosed pliers though lol. Still can't get it out though.

So you snapped your Circlip pliers trying to open it up instead of squeezing it together and lifting it out, Even when you squeeze it together it's pretty tight to get out, tough little circlip that one.

Yeah lol. Just took it round to my Chairman's and he had some better pliers and managed to get it out.
Gonna take the drive shaft tomorrow evening.

Nice one!  

Looking at the diagram from the workshop manual..the spring in the shaft slides in and then there should be a bolt? Well mine doesn't have one, the spring just slides out. Also the spring I ordered for to replace is nothing like the one on the 800. It's much larger in circumference and shorter in height.

I've not dismantled the VS1400 drive yet so can't compare but if it is wrong I can just use the original VS1400 spring yeah.

If you have ordered the VS1400 spring as a replacement for the VL800 spring, yes it is much larger and should be used if you have it.

How does it fit in the end of the shaft? It's way too big.
Also when shortening the shaft should it have the slight taper on the very end that it has stock?

It just fits in the the gap (stopper bearing) you have removed the drive shaft end from and the drive shaft pushes against it.

Ok nice one Dave.
When the length of the shaft is shortened does there need to have the taper like when it's stock? The photos look to be without it but others look like they may have it.

I had mine tapered slightly, to make it slip into the universal joint easier.

That's included in the length that's left then yeah after the correct amount is removed?

Have it milled back by 3"/16th's so it's the correct length, and then just round the edge off the end of the splines slightly so it slides into the universal joint easier, no where near as much as stock though, like the top one in the pic.

 

Which end of the spacer gets the length taken off? The thinner part drops into the drive.

I've dropped the shaft and spacer off. The guy was saying that with the description in this image it says that 3/8" is taken back and 3/8" forward into the spline to make the 3/16". Is that correct?

The thin end of the spacer is easiest but any end will do, Machine the "end" of the shaft back 3/16ths and the shoulder back 3/16ths, don't mill into the splines! Mill them both in the same direction! towards the end that goes into the drive. There's an arrow between the two lines pointing in the direction it needs milling in the photo above, where it says machine shoulder back! "NOTHING" should be 3/8ths "NOTHING" or it'll be wrong.

Bloody hell!  if i attemped owt like this, the bugger would never run again

Fuck that, you are allowing a fucking idiot that can not read simple instructions and drawings to do your modification. We have not said that anywhere & if you are getting instructions & pictures from elsewhere then ask them & not us as it is making a simple job sound harder than it is.
I do not want anyone put off doing this easy modification that I have explained in full in the "Modifications Done" section due to there lack of ability to understand what both myself & Sim have written in the other thread.

Like this.

I only have Internet access on my phone. Images on here don't always show up for whatever reason. Yes I have instructions but not always images. I managed to email the pics to my mrs at work to print off so I had a couple of things with instructions to give him. I got the other image from the VR forum where I could see the image.
Typical as right now they are all showing up.
I text him last night and he knows he misread what it says.
I sometimes over think things which do complicate things and I know that.

Rattler just keep asking the questions mate, as people don't always have the patience & respond in the best ways and have the courtesy & consideration we always should. I would rather you keep asking the questions and get it right & enjoy the end product in the way you should.
Better to over think an issue than not think enough, I would rather you ask the questions that make it clear in your own mind.  

Cheers Dave. Took the 1400 drive apart today. Took about 20 seconds in total to get seal and circlip out lol.

You are so close now & are going to love it. funny how something can give you a headache and then then you have a eureka moment.  

An exceedingly good modification that I have previously read about at some point. Is there a recommended thread area to show the final example or findings in full? My apologies as after searching this area, I have not as yet been able to re-find the one that had been written.

Have a look at this LINK Ken  

Picked up the shaft and spacer today. Changed the rear shoes too so really it should be just elongating the holes and finished but I got home to find my Mrs had been tidying..emptied my bag of parts on the side and threw the bag away. Now I'm a seal missing   
Dave..sent you a PM mate.

Got the PM & just replied but nothing in it?

Which seal are you missing?

The one that goes over the top of the circlip mate. Gonna order another tomorrow.

Bugger I have several spare ones but not that one. At least the come very quickly & then your going to be so pleased that we will be able to see your smile from here.  

Got one in the garage Rattler    Send me your address and I'll post it tomoz, Or pick it up over the weekend if your in a hurry?

Simbo have you got my PM? They seem to be storing in the outbox.

Yeah mate, just got them

Elongate the holes and test fit the drive a few times before fitting the shaft and seal in the drive, It makes for final fitting without hiccup
