The K0 swingarm and axle adjusters arrived from mr. monkeyclaw, mr C's parts or whatever off of Ebay. The swingarm is pretty decent for $70 and the chrome on the adjusters is really good.
The engine is another matter, the interior is pretty dried up and there is a lot of varnish on everything. I may just clean the cases and swap in most of the internals from a different engine.

I got the trans mainshaft removed from the clutch. This is the first clutch I've had that still had the K0 clutch ring on it. The frictions are trashed, I soaked the steels to see if they will clean up. In the past an orbital sander has worked on them with good results.
My 5 gallon bucket of PB blaster solvent will get a test. so far so good. I soaked the bad oil pump parts to see if there are any parts to salvage. I had one before with a different part of the casting broken so maybe I can re-use this one to make one more good pump.

It got up to a balmy 20 degrees F today, so I took the engine case, and cylinder to the car wash. I forgot the head. I'm inside now with dry socks and sweat pants warming back up. I was able to pressure wash the oil galleries and get it 80% clean. It appears to have some Permatex on the cases but the mud and tar mostly came off the outside and the whatever was in there is mostly clean now.
I'm not afraid to use my $80 bucket of parts cleaner now without ruining it on one job.
The head was mildly ported but sustained a chipped intake on #3. It has no valve seals on the exhaust side indicating it's early and it had stock valves.

I remember taking two engines to an independent do-it-yourself sprayer car wash with good pressure;I had the car in the bay and pulled the engines out of the trunk,along with the can of foaming Gunk and a brush which I got real busy with fast. I was able to throw away the Gunk can and hide the brush in my car trunk before the guy came out.
I was in there for about 20 minutes and the owner/attendant came to 'check up on me' and caught me washing the two engines;the man had a 'fit' about it.

I can see where the car wash guy might get ouchy about a bunch of grease like the semi's leave in the truck bay. We don't really make a big mess though, I think the bay was cleaner when I left.
Besides, I saw the guy leaving before I backed into the bay. L0L.

The place that I went to,the guy was upset because I was taking too long;he was hoping to get more customers in that bay and thought I was causing him to lose business.
I found a bigger place to go(Greensburg,Pa.)after that;he had a legitimate gripe because it was a small place on a country road,local people and only had 3 bays and the weather was supposed to get icy that night..
I don't want to be near stressed-out folks anyway.

I'm lucky enough that there's a place near me that's almost fully automated- it even advertises there's no time limit. 10 bucks, and if the sprayer times out, you just hit the button again and keep going.

Did my engine cases and hit the Jeep too while I was at it.

Don R · « **Reply #857 on:** January 20, 2024, 04:27:20 PM »

I'd do the 10 buck no limit wash, my truck would have gotten washed too.

I'm still cleaning the cases and preparing to move all of the internals from another engine to this crankcase. I'm going to clean a sweet set of rods and check the bearings after getting the main bearings plasti-gauged. I got a low mile oil pump and another transmission set aside.

Do you use a pressure washer to clean greasy engines before disassembly sometimes ?

BenelliSEI · « **Reply #859 on:** January 21, 2024, 08:27:05 AM »

I have an old Honda pressure washer that puts a car wash to shame. Hooked up to a hot water tap, it works miracles. I have an old sheet of 1/2” plywood that must go under the parts or the grass, weeds and mud goes everywhere! Any small parts get screwed to the wood first.

Don R · « **Reply #860 on:** January 21, 2024, 12:33:27 PM »

I've toyed with the idea of a hot water tap, maybe a pair of ball valves to switch back and forth from cold to hot. The best idea would be a wall hydrant for each, that way I wouldn't need to run pipe from the crawl space into the kitchen sink cabinet and back down.
I have washed them before disassembly but I'm trying to not re-enact my hernia so I put this one on the bike lift with my chain hoist and took it apart there. Sometimes I just work on the floor for the sake of getting the exercise.

This trans was in a box, I noticed the rings around a couple of the gears, does that make it an F transmission? The final gear has the same tooth count as the one that was in it. It's been in the solvent tank but still needs to be cleaned.
An old shift fork was rubbed pretty bad also. I need to use the ones that came with this trans if I use it.

PeWe · « **Reply #862 on:** February 03, 2024, 01:35:56 AM »

If you need to verify the trans to be K0-K6 vs later, F included
http://forums.sohc4.net/index.php?topic=169359.msg1965282.msg#1965282

The later trans has different gear on final shaft.

Here early (left) vs late (right)
The early one got the late final gear with new bearings after photos were taken to match the later trans that engine will get. Higher revs on 4-5.

That engine not yet assembled.

Don R · « **Reply #863 on:** February 03, 2024, 10:25:10 AM »

I have installed a backcut F2 trans in a K6 case, so am a little schooled in the differences but that engine is still on a stand waiting for a cylinder and pistons that may hold up to the turbocharger. Too many projects get in the way.

PeWe · « **Reply #864 on:** February 03, 2024, 10:37:26 PM »

I have not assembled my bottom end yet. K5 number (K2-75 here)
Also backcut late trans.

Don R · « **Reply #865 on:** February 04, 2024, 08:31:52 PM »

I've tried some different trans parts, I got a couple from a mini sprint car guy. The downside is it isn't one or two complete matching transmissions. I've been able to get it to go through the shift sequence a couple times but fifth is sometimes an issue. I have the original 1970 narrow path shift drum but was trying a later one, I may go back to the original and try it. It seems like the center shift fork is hanging up, it keeps trying to move the shaft with it. I cleaned and lubed it but not good enough apparently. One mainshaft cluster had one ringed gear, it had the same count as a different non ringed one but the book has a different number of teeth.
I called a wasted day and came inside.

Don R · « **Reply #866 on:** February 29, 2024, 06:35:35 PM »

It was missing a thrust washer (found on the bench) and haven't put the neutral safety switch in it yet. Those would probably make it shift properly.

I returned #1 K0 back to its wire wheel stock exhaust condition, it was a former BOM winner with Lester mags. It has the proper K0 front hub and early rotor and a 2-hole rear hub although riding on new spokes and DID rims. The wrinkly seat is an original. It got new BT46 tires this time.
Building these wheels took a long time collecting the parts, and a covid project finding rims and re-lacing them. I finally put new tires on them and installed them.

PeWe · « **Reply #868 on:** March 06, 2024, 08:41:19 PM »

Those wheels make bike look very good!

grcamna2 · « **Reply #869 on:** March 06, 2024, 08:59:08 PM »

The paint is awesome Don

I think your K0 is a K-nock O-ut

Don R · « **Reply #870 on:** March 07, 2024, 03:31:50 PM »

Thanks, compared to the pic on page one there is quite a difference.

BenelliSEI · « **Reply #871 on:** March 11, 2024, 12:36:24 PM »

That bike has come a long way. Looks fabulous!

HondaMan · « **Reply #872 on:** March 11, 2024, 01:13:16 PM »

Ah, and in my favorite color, too!

SOHC4 Cafe Racer Fan · « **Reply #873 on:** March 13, 2024, 06:13:07 PM »

This bike still looks like a BOTM winner!

Don R · « **Reply #874 on:** March 19, 2024, 09:18:21 PM »

Thanks. I even have an early head diecast motor in case I want to get really crazy going original.
