Thanks Bryan. The stud snapped at the base of the casing. I'm taking the parts to work for cleaning in our parts washer, maybe i'll try an see if i can drill it out.

Got the engine cracked open. Primary chain is past replacing too. One of the cylinder studs snapped despite soaking it for 24 hours. Well that's just perfect. What's the story on replacing one of the casings, that is a no go right? This is the first time i'm working on an engine, other than mopeds. How do you guys measure crankshaft shells? They look fine, but have 42.000 km behind them.

Its a shame some butcher has been in there before you, stripping threads and whatever else.... hope you can sort it out. How cheap / easy are spare motors to get hold of? Might be worth investigating before spending loads on that one..... Good luck mate !

Not that easy around here. And i sleep better at night knowing what parts are in my engine :) But could see if i can find a new head in good shape. As of now, i've noticed at least 5 bolt holes with questionable threads.. Too many for my liking.

Thank you! And thanks for the tip about photos and a list, that's a great idea. Just had an hour to spare this evening, so started to take the engine apart. Oh boy. Bought it because of the low mileage, but this engine sure has seen it's better days. 4 different types of bolts keeping the rocker cover on, threads coming out of the bolt holes, couple of helicoils here and there.. And the cam chain has eaten a good part of the cases. Not what i wanted to see. Really hoping that i don't have to change more engine parts other than the cam chain system and new bolts. As a student theres not much to spare in the budget. How do you guys get the head off? Just a couple of punches with a rubber mallet?

That thing looks broken. Wonder where the other half is..

A little bit of progress.. Just pulled the engine out today. Need to decide what i wanna do first, the engine or the frame. Might end up disassemble the engine to find out what parts i need, and then move on to the frame while i search for parts. Saw that cruzinimage doesn't have any 466 kits for the 400f at the moment, heard a lot of good things about those.

So disassembly, cleaning, measuring, order parts. And then clean the frame up, blast it and paint. Fix the wheels and front end so i'll have a rolling chassis to set aside. Going to get a new wiring loom and consoles from DSS. Was quite happy with the quality on my last bike.

The steering lock in the ignition lock usually means it was a U.S. model, but you can be sure by checking the frame/vin plate. The relays to the headlight were probably to allow the use of a higher wattage headlight bulb without putting excessive load on the existing wiring and switches.

I've never understood the system with the frame numbers. My frame number indicates that it would be General Export, Australian, German, French, and so on.. 1051697.

Welcome to the forum Wiinberg,
Looks like there's enough work to keep you busy over the winter.  I did the Superdream front end conversion back in the 80s.  It stopped OK but didn't look pretty.   Back in the 80s it wasn't a classic then, just another ornery bike.
When I went to the Police compound full of stolen bikes, two years after it went missing,  I recognised it straightaway by the odd wheels.

Thanks! Yes, and bit more work than i first thought, but that's the way it is with these bikes. Took the tank and rear fender off today, noticed a couple of red wires that shouldn't be there. Traced them to under the tank where i found a big birdsnest of wires coupled with two relays and then on to the head light bucket. Have no idea what they are for. I hate electrics. My last 400 i replaced the whole harness, already thinking about doing it on this one too  ???

Also noted a couple of differences from my old one, this one has the passenger pegs mounted on the swingarm. And the steering lock built in the ignition vs. on the steering stem on my old one. That's pretty cool.

Hi and welcome to the madhouse. That looks rather like a Mocheck Harrier, which was a conversion a British company did to 400/4's back in the 70's. Be interesting to know if it was one or just similar looking. Anyway, good luck with the work on it.

Thank you. That sounds interesting, do you now of any way to identify it, what i should look for? I don't have any history on it sadly.

Welcome from me also. Looks like a great project. But I pity your poor back as you don't seem to have a single working surface!

Peter

I'm on the lookout for a small hydraulic stand, to get it off the ground in an acceptable height. That would be much appreciated i think.


With regards to the dual disc, i'm not sure what route i'll take. Maybe 550 front end or welding brackets to the right 400 leg if i can find someone to do a nice clean job.

Hi all, thought i'd start a thread with my new winter project. Bought this 400F a couple of weeks ago for 1200 pounds (that's about the cheapest possible for 400F in Denmark). It has 26.000 miles on it and in need of a lot of TLC. Also gonna be opening it up, as the cam chain rattles like a hunting party of rattle snakes. Who knows how long it has been doing that.

This is my second 400F, and this one feels a bit under powered. So yet another reason to have a look on the engine. Going to check the compression before disassembly.

Not sure what the path is with this one. I am strongly considering a 466 kit, and also toying with the idea of dual disc up front. I'll see what the future brings. And to the most important part, some pictures.
