Knuckle progress

Its time to post a few pics from the ongoing repair of various issues I find when I wrench on my 39 Knuckle.
I was supposed to replace tires only, it have become quite a bit more extensive, sigh! I should not be surprised, this bike have after all been used for years and years and served its previous owner for a great number of miles/km`s.

Here are some pics as a starter, will add text to them later.

Shimming the rear sprocket to get it centered to the wheel center, IMPORTANT!!

The old rear wheel sprocket was welded to the drum, hmm, and its the hardest piece of metal I have ever on my work bench, one can just wonder what Rockwell this have! 

Rear sprocket riveting tool.

Drum and sprocket in the tool.

Oops, this pic should have been presented before the last one. Make sure the four centering rivets get their heads shaved enough to ensure all other rivets are laying firm on the riveting tool.

A variation of riveting punches.

Removing worn front fork rockers.

Front fork rockers and new parts.

Changed all bushings in the front brake, four of them.

Having removed the tires I found rims to be pretty rusted. Had to remove all rust with a rotating wire brush, a shit job.

Lets hope the spoke nipples can take some more years of action.

Rust killer.

Horn was located in two home made brackets. After removing the horn I understood why. The rear part is from a VL, its not a 9 bolt one as supposed to be to fit the original fasteners.
 OK, this need some attention.

A box of spare Delco horns (from cars) is a must for every home.

Horn bracket mess.

Phew, horn is now a 9 bolt and original brackets are on.

Horn as it was meant to be.

When I removed the two rear screws for the inner primary cover I soon realized it was cracked in the front. OK, then I needed a clutch hub puller. Very hard to measure the TPI in the clutch hub, and several attempts with google gave no other answer than Jeff aka "Hollywoods" excellent description of how to remove a 39 Knuckle clutch. OK, I contacted Jeff trough facebook (oops I forgot the time difference) and he was kind enough to measure his HD tool, 18 TPI. Off to the lathe and let the chip`s fly, voila soon I had a clutch hub puller.


Ready for some grinding action. Will use a reinforcement plate from W&W when I build this back together.

Feels like the poor ol Knuckle is coming more and more apart, rather than getting fixed!!

Good people, audience of this blog.
Meet Trygve and his Indian Power Plus.
Trygve, born in 1895 traveled to the US in his younger years, he lived in Chicago and worked as a carpenter.
Maybe he got influenced by motorcycle addiction whilst he stayed in the US? I think so because motorcicles where rare in Norway in those early years when he departed for the US.
Trygve returned back to Norway just in time before the WWI broke loose. He settled his new home in Lillestrøm, and started to work with Strømmen wood-outlet. We can assume that Trygve did well, as he after the first great war had ended contacted Sontum & co. in Christiania to order a brand new Indian Power Plus.
Trygve was a true motorcycle enthusiast and rode near and far on this Indian for years.
I found those pictures by coincidence in an archive on the www, where they had no information, just a name of the rider. I was lucky enough to get hold of Trygve`s grandson Vidar, a keen motorcycle rider himself (it might be in the blood?). He have been kind enough to give us the information to follow the pictures when presented here.

A cool detail is Vidar had not seen any of those pictures except from one before, and they amused him as much as they did me.

Mr. cool!

Yes that is for sure, winter came this year too. Snow, loads of snow. Who does actually need snow, I mean other than those guys that make their living from snow plowing.
And cold, oh my it was cold for a week or more. Down to -26 degree C during night.
Had -3 degree C in the workshop, was not tempting to get any thing done there.
Luckily I have small fire stoves in my two small workshops in the house, and by keeping a steady flow of firewood into them I managed to get some done.

Restored the WL stroker motor carburetor, its built from a Linkert M74B, a Panhead carb that is. I like working with the old Scheblers and Linkerts, they are maybe not the best of carburetors, but they are so sexy, yes sexy as any carburetor might ever be.

Carb is fitted to the special manifold made by Vegard. Peek manifold seals in the white box. Cant wait to fit the manifold to the cylinders and pressure test. Pressure test tool for Linkert manifolds seen to the right of the carb. Made a aluminum jig wich I fit to the carb when working on it, makes it more convenient to locate on the bench or in the vice.

OK, OK, could not resist making a photo of the Schebler DLX special built for the cutdown motor.

Three specials, Linkert in the middle and two different Schebler DLX`s on the sides.

Got a pair of STD bore 61" Knuckle pistons from Matt Walksler for my cutdown motor, thanks a lot Matt.

Had to bring four cylinders in need of heat resistant paint down to the steam train guys ( they have a 100KW oil burner keeping the entire locomotive stall above 20 degrees all time) to get some decent temp for painting. Turned out well, but my nostrils and my throat was black for two days after.

The later style J & JD cylinders have 18mm spark plugs.
Problem is there are no spark plugs this size available today (not that I have found) that is long enough to get the spark into the head as supposed to. I sacrificed a couple of old 18mm Defiance spark plugs to make adapter for 14mm plugs with long neck, this move the ignition 1/4" further into the head.

When done the 14mm plug and adapter looks as the old style spark plugs that could be disassembled and overhauled.

You might remember I rebuilt a 50ìes Panhead handlebar with springer style ends. OK, got it back from the painter and fitted control cables and switches with wiring. Looks good when fitted in the 3" risers and the offset triple clamp (that I found at the Davenport meet in a bucket filled with Thriump parts).

Dual headlamp Harley VL from 29 -30 with sidecar.

1925 Harley model F 1000cc / 61". Easily recognized as a 25 due to the gearbox, last year with this style.

I got this last photo from my friend Fritz. This is Haakon Hestnes from Bergen, and his 1928 Henderson with sidecar, a stunning machine both then and now. Wonder where this ended up?
