1972 450CR

The crank looks like it sat in some water but the cases look great.

luckily thats before they started using mag for the cases or they would be trash...

I am pretty happy with the condition of the cases. Sometime next week I'll strip the paint and clean them up for painting. I found a lot of the engine parts I need. I got lucky and Huskydoggg had most of what I needed for the engine. He was great and tolerated my adding to the list on a daily basis. To bad he is shutting down the business.

The odyssey continues.

I cleaned the corrosion from the clutch cover, couldn't really get a clean result so I took it to a shop and had it bead blasted.

Good job and it revealed the corrosion had penetrated the clutch cover. This explains the left side of the bike being covered in oil. I try to restore as much of the original bike as I can without using parts from other bikes but this one I may have to replace. There is a lot of corrosion! I may experiment with JB Weld and see if I can salvage the cover.

I'll post some pictures tomorrow.

Now on to the ever present search for paint.

I have combed through the site for the various paints and codes for the frame color. I believe I have a good alternative and it's a marine grade fuel proof paint. Moeller Honda Silver Metallic; looks like a good match. I don't believe it will be an exact match but my restoration will be a nice rider, not museum quality.

For the engine cases I found the POR 15 Chassis Black is a pretty nice match.

For the tank I am willing to pay for quality dent removal, polishing and painting because the tank is such a visible Husky mark. So who would you guys recommend?

Mike

Send it to Darty, Lol He is a master husky tank painter...
I just found out about Huskydoggg too , Steve has helped me out time and time again . He is a good hearted person and I consider him a vital resource to the Husqvarna community .

Steve is shutting down Huskydoggg.

I managed to get the top end and bottom end from him before he shut down.

This is great stuff. Keep us updated Mike. Can't wait to see the 450 hit the road.

Here is a picture of the clutch cover corrosion.

wow... is it thru & thru?...
I did a 450 restoration....lots of what you found I too realized

Yes, it was through and through. I would replace it but the other covers I have looked at are damaged in other ways as well.

Does anyone have a legible schematic of the transmission componets?

Try copying these and blowing them up, might be legible enough. Other wise I can send a PDF. Also have clutch details and service procedures if they would be of any help.
Steve

Thanks Steve.

I have that schematic but it does not lend well to enlargement. I was hoping for something with sharper definition.

I certainly could use the clutch pointers. While I am experienced any many things; the Husky is not one of them.

I was going to send the tank off to day but discovered the weld in the area above the frame backbone was leaking fuel. Having a lot of problems coming up with a second over piston assembly.. I have found new Wisecos' on ebay but $337. I made an offer of $275 and he came back with $335....finally just gave up on ebay. One ebay seller had one for reasonable but couldn't tell me what the measurement was, he said it was 2mm over stock... possible but without him measuring the piston I wasn't going to buy it.

I am finding the 450 difficult to source parts for at a reasonable cost. Seems everyone I contact says parts for the 450 are rare.

Mike

Nothing in the 2nd over piston so far.

I pulled the forks apart. Found about 200cc of H2O in one leg of course the spring was coated in rust and the steel fork tube as well. Cleaned about 3/4" of dried crud from the bottom of the stanchions, man did that old oil and crud stink. Thankfully I live alone and was able to put the parts in the dishwasher for a good hot bath.

I have an email to Race Tech. I'll get the springs from them along with emulators. Fork tubes seem pretty easy to find but I'll try to salvage the originals.

Cleaned up all the transmission gears and shafts they look pretty good but I have questions on the shift fork wear. They look robust but I still would like them checked by a Husky wrench.

Glass blasted the engine cases and outer covers then gave them a good hand wash followed by two cleanings in the dishwasher to be sure I got all the glass beads out. Painted those with POR 15 Chassis Black. Good stuff and a good match but the purist will have to be the judge of that.

Got the tank drained and ready to send out but found a crack in the weld of the leading edge weld of the fuel tank. I hope they can weld that up.

I packaged the crank and it's ready to send out to Oconnor racing. Motoplat is packaged to send to Vance for rework.

It's going along but slowly.

I'll post pictures when I get off duty.

I would like to see what the POR 15 looks like. Sounds like you are moving right along. Nice progress.

Finally home so here are a few pictures, The covers are done with the POR15 Black Chassis and the air filter cover is done with Moller Marine Paint, Honda Silver Metallic.

Mark V mod 0 sounds like a Navy Seal knife ? nice restoration !!!

The POR 15 looks nice to me.

I took the frame to the sandblaster. This guy uses a fine sand that leaves a finish something like a 220 grit. They restore classic bikes so I trust them in this regards. At the very least I would have to lightly sand the frame.

I finally got my hands on a good set of bore gauges and outside mics. Just confirmed my feel...I measured 0.10 piston to cylinder clearance. To much for me so I will have to go at least to the second over piston and ring.

Here is a picture or two of the cylinder and head sitting on the cases, all empty but gives me some satisfaction.



I thought this odd, they stamped over a number:
