Hello All
New guy here. I'm starting to resurrect my Hurricane. I bought it around 1983 give or take a year. Rode it some for a few years and then it got parked. Life/work got in the way. I've decided to get it running again. I'm sure I'll have some question as I go along.
Please note this is a resurrection not a restoration. I want it looking nice but showroom condition is not what I am after. Then again I'm not going to harm it to where someone couldn't do that after the key is pried out of my cold dead hand.
Thanks in advance for any help I may get from this forum.

Couple of questions.
First would it be better to start a new thread for each question or just post them in this thread?
Second how do I get a picture to display instead of the link?

I vote for keeping it all here...

The forum will not show a picture that doesn't end in a graphics extension like ".jpg".

Try a free account at flickr. You can right click and save the location of pictures you post there and past them into the link editor here and they will show up.

That's a nice looking treasure you have there.

Thank you.

Getting ready to remove the engine. Made some lifting tools. Do these look OK? Is there a better way? I've never removed a engine from a triple before.

I understand that. I'm trying not to get too much stuff torn apart at once.

If you have another person that is enough but it would be 10 pounds or so lighter if you removed the primary drive, inner primary case and clutch. Easier to remove the gearbox sprocket now too.
It could be stripped to just the cases with the crank, rods and cams.
If you do not have an engine stand it makes it easier to do this now.

I will have help. I am building an engine stand. It will be done before I pull the engine.

What I was really wondering was if anyone sees a problem with the lift points?

Question. Has anyone re-laced a Borrani rim? If so is there anything different about it compared to other rims?

Been a while since I posted. Parts back from powder coating. Starting to re-assembly bike. So far so good.

End of year update:
Oil tank repaired, powder coated and installed

Rear fender arrived yesterday. It's a re-pop. An old one at that. The newspapers that were protecting it are from the last century. It wasn't exactly a bolt on deal. Took a little massaging of 4 of the mounting holes to get it to bolt up and a little bending to get the chain guard to play nice with it. All in all I'm pleased with it. Have to be as it was the only one I could find anywhere.
Tie up a few loose ends and she's a roller. Next up start on motor.

Hi GLJ

Great to see that pretty bike going back together. I hope you Triple checked that there was no blast media trapped inside your oil tank! I am sure you would have checked. only saying because I have seen some awful engine damage caused by builders getting more excited about the shine an making progress.

Best regards

Esme

Funny you should mention cleaning the oil tank. I had it installed and the battery tray back in when I realized I had failed to flush it out. frown Oops. It's clean now.

Engine apart. Head and cylinders at machine shop. Going to have to go 2nd over on the bore. Picked up a new set of 2nd over Hepolite pistons at a friends shop. Not sure where or how he got them but they are old. Packaging had made in UK on it. I'm hoping they are the real deal. New clutch, gasket set and other parts on the way from UK. Seal kit coming from Colorado. Still need to inspect the rubbers in the chainwheel cush drive. Pretty sure the valves and guides are getting replaced also.

Sprocket and seal plate. Sprocket has strange wear. Seal plate shows signs of chain rubbing on it on the left side. The bearing on the main shaft feels good. If the bearing was getting loose I would have expected rubbing on the right side of the plate. Not sure what to think.

Not sure how much farther to go into the engine. One side of me says finish cleaning and when new gaskets and seals show up start putting it back together. From what I remember there were no bad noises coming out of the bottom end. The other side says keep going. Split it apart, make sure the crank and rod bearings are OK. What to do, what to do?
Couple of question. The valves I'm looking at getting are Kibblewhite Black Diamond. Are they good enough?
What is the best valve guide to use?
Anything else I should think about doing to the engine or valve train?
All comments will be appreciated. I've rebuilt engines before but never a Triumph.
I'm sure there will be more questions.

Another question. How do you get the oil pump out? I have the 4 Philips screws out the manual says to remove. It won't budge. Is there something I'm missing? I would like to take it apart and inspect the gears.

There is a tool to do that. We sell it under the part number CS-0202. It is a threaded rod with a T handle. It threads into the back oil pump plate and pushes teh pump out.

Does sprocket seal "left" and "right" refer to front and rear of the motor? The front edge of the seal holder will be hit by the chain if you run too small or a sprocket. I think 18 tooth is as small as you can go. That sprocket is way too far gone.
I had to make a new seal holder as I was starting with a four speed which had a different size seal I.D./O.D. The five speed seal is not standard so I went to a metric seal that was.
Kibblewhite valves are nitrided, others are hard chrome. For longevity you do not want plain stem valves. I am using Subaru 7mm stem nitrided valves.
You will get a thousand answers on guides here.
The two remaining screws in the oil pump screw into the back plate. The tool John refers to go in place of those screws.

John
Thank you for your reply. I'm kind of new here. Who would I order that from?
Thanks

Yes
It is 18 tooth, as far as I know it's the original sprocket. It is going to be replaced.
