As a teenager I built a Triton in my bedroom.......my mom helped me get it downstairs! Ahh memories.

Paul.

Wow, you guys are more than a little bent!


OG

Ahh, the wait for special order parts... Yep, Rob I'm not messing about with the pinion so it's not rocket science. I'm putting together a proper how-to with full pics for a friend so let me know if you want one.

I betcha didn't put oil in till you got it outside.

C'mon K Freak, you don't worry about things like that when you live with your parents...........

Paul.

Gawd knows I ruined more than one garage floor when I was a teen...

The last back order stash finally arrived so hopefully I've not forgot anything and we can get this show back on the road!

ohh goodie!! ....love opening mystery bags ....whatcha got ?

Lol, yeah Chaz my roommate calls them my little "fix" bags. Let's see: Shaft seal, FD seal, some mounting hardware for the newer Mk. II fender, some rubber bits of course, and I finally broke down and got a new oil pressure switch loom and the corresponding sender unit...

cooooool !!

Spoke with Dave at GP today and the Showa forks are finally done so I'm going to try to pick them up on Monday. The man really knows his craft and I looking forward to trying out the rebuilt bits. Fingers crossed I've finally got everything to do the front end... I'll try to get some more pics up when I get a chance.

sweeet !

My Mum let me replace the timing chain on my R75 back in about the Winter of '78 or '79 in the kitchen while she baked some tasty goodies in her wood-burning stove/oven combo - we were of the 'split wood not atoms' variety growing up. Dad helped me wrestle the motor back into the frame (I didn't know I could have done the job motor-in 'til later on).

I luv these stories guys and thanks for sharing. It's good to know I'm not the only one who had an interesting childhood.

OG

Picked up the forks from Dave at GP suspension this morning. He does outstanding work and I'm looking forward to getting this installed... If you're wanting to get your front end properly sorted out give him a call.

OG

These came out of the forks and I was wondering if anyone knows if the stock German springs were progressive in design on the k75 Showa fork?



THanks,

OG

looking good og........finally you can make some money by selling what folks are looking for



cheers

Turbo RT. :-P

Side panels arrived today from Motobins. Under $20 shipped to the US. Thanks again for sharing this with everyone Paul!



OG

Well, looks like I found the culprit on the leaking FD. The surface on the ring gear that mates with the seal definitely needs some work...

OG

To put it into more technical terms I would say at a glance that it is Shagged. There is a good possibliity that the rust goes deep enough to prevent repair.
You may be able to get a speedy sleeve, a stainless sleve that goes over that area and makes a new sealing surface.

hard as nails that stuff og ....good luck mate !!!

Yep, Freak those were pretty much my initial thoughts as well..I'm in process with trying to clean her up Chaz so we shall see...


OG

Well, once again I'm impressed with the quality of the components in our old girls. A quick dip in Eastwood rust remover and some work with 000 steel wool took care of the rust, and than a little final work with some super fine emery cloth and it's good to go.



OG

Hi OG,

Good to hear that the side panels arrived OK. Bins still have them listed today, still @ £9.90 a pair.

With the rear seal, if the original surface is pitted it is possible to leave the seal slightly proud of it's housing, thereby allowing the seal lip to run on an unworn area of the bearing carrier.

Cheers, Paul.

Yep, definitely worth posting that link again Paul. Stateside those go for anywhere from 75-100 with intact mounting brackets and in great shape like that. Just a crazy deal.
Also, a great tip on the FD seal!

OG

All cleaned up and ready to go back together after the gear spends some time in the freezer...



OG[b]

Great work, OG. That FD seal tip applies to the main drive seal as well. That accounts for the recommendation from BMW to leave the seal 0.5mm proud of the engine casting.

Ahh, now that makes sense...thanks for the enlightenment Rob!

Ok, guys messed around practicing with the old seal reinstalling it using a duct tape roll adjusted to the proper size as a drift and also played around with pieces of wood cut to size and what not. It is a fiddly job and its very easy to pop the seal thru the other side and variations on that theme. Since it was so easy to separate the ring gear from the inner case half once it was heated up, I simply applied moderate pressure with both thumbs and it popped right out, I thought why not try the same sort of technique with the seal. I heated up the case half to only about 50 C vs. 80 C for removing the ring drive and than lubed up the outer edge of the seal with a bit of silicone spray. Wearing some thick rubber gloves I was able to pop the new seal in with moderate pressure from just my thumbs and get it aligned quite easily there after all with no drift or hammering. Also, installed the seal very slightly proud so it is working on a new spot on the drive gear. Thanks again for the tip on that guys!



OG

Ditto for no drift needed for putting the gear drive back in the case.

great job og ....goodonya mate !!!

Thanks mate. Happiness is a dry garage floor...




OG

Wonderful work!

Oldgoat
Great work on your bike. You make me want to start tonight on my bike. Oh I have 30 goats on the land here.
Ozley

Thanks BR & Ozley I just caught your introductory post. I hope you & your son will post your old girl in this section too. Would luv to see a pic of all the goats if you get a chance...

OG

Ok, quick run to HF this morning to pick up some bits and now I think I'm finally ready to do the front end swap. Also, got one of their cheap front wheel chocks so I can finally setup the preload, rebound, and I'm sure do a little fine tuning on the new fork as well.



OG

OG, brilliant stuff, that bike will be so much better than new by the time you're done.

I remember my Dad taking me to pick up my very first bike, a Vespa 70cc - but the less said about that the better!

Best
Dave

Hi OG,
Can I request if you are putting together a "how to with photos" for a friend that you also post it in the How To section here. Your excellent work would be a guiding beacon for all of us if we have to go down the dark road of fixing the final drive.
Regards,
K-BIKE

Thanks Dave. I've got very fond memories of tearing around on a Vespa with a nice passenger or two when I was a young hooligan...

OG

Hey K,

Not sure about the "beacon" part as I've probably cocked-up at least 75% of the seals first time thru on the bike by now. Anyway, once I discovered the driftless method and realized how quickly this could be done I just had my buddy drop his FD off and changed his out in maybe thirty minutes max. When I get some more spare time I will try to edit some of the pics I have and add instructions. If I'd have been thinking I would have had my buddy take a movie of the repair with his phone.

OG

Putting together a very poor man's brake lathe so I can do the rear disk before putting in the new PF pads...

Ok, you're definitely going to want a second set of hands for this setup, but the Flex-hone is great and makes quick work of the job.

nice one og ......that looks a great way to clean up disks ...some great inginuety

couldnt you use a external drill speed controller to vary the speed of the disk ? so that you can set it and just use the on off switch on the drill propper ?

used to have a couple of em around the place ...

Thanks mate...off to do the crank seal now.

Never done that mate...sounds like a neat idea.

Blimey OG that bike looks so good hey you must have your own postie you have certainly been keeping yours busy , there is enough material here for a mini TV show forget Tank rebuild lets have a BMW K100 rebuild. Joking apart fantastic job mate.

Talking about jobs in the house who remembers the old chain grease you could buy in a metal buiscuit type tin which you warmed on a stove the grease melted and the chain submerged into a steaming stinking tin and liquid grease worked its way into the rollers, you then fished it out and let it cool job done, well I used the old ladies cooker once and got a thick ear for my troubles long live shaftdrive.

BIG D

lol fundamental words of wisdom d ...."long live shaft drive"

Duckhams Chain Guard I believe it was called. Used it for years. Marvellous stuff.

Ah yes Duckhams I have been beating the brain cell for a while to think of that, I knew it started with a D.

Here is a close relative:
