All over the place...Maxim/Seca build

[Jeff0133]

Got bored with the cleaning/blasting so I did a little destruction.
Remember that 100$ donor's bent forks...?

I really wanted a look inside as they were 2 inches shorter than my Maxims...Well, they where jammed shut...couldn't budge them for the life of me.
So I took to the trusty grinder to cut the stuck top off and the bottom where the Allen screw sits...not like I was going to reuse bent forks anyway, but was hoping the insides would be good...

Progressive 20 inch springs!
This donor keeps on giving..

Started painting today...just the covers to get a handle on it. Followed instructions to a T.
Using VHT flameproof ceramic enamel.
Hope it holds up good,spent a metric f..ck-ton of time and elbow grease and cursing on the prep so...fingers crossed.

Primed

Painted.
I know,I know white Will make it messy but i want a black/white scheme with maybe graphite wheels,tank,fenders with white striping...
I'll just have to live with the maintenance...like I said she's my princess...

 

[Jeff0133]

Painted the cylinder and head flat black..

Had to use a 11/2 inch steel tube to support the cylinder as I learned that at 400 degrees C...the sleeves come out!..
Good to know for that eventual Big bore sleeve change.

 

[Jeff0133]

Case halves painted...oven cured

 

[Jeff0133]

Still waiting a bit on the engine rebuild...thought about Big bore...probably not.
Whilst waiting I painted my swing arm.

And stripped the paint off of the xs400 special tank I bought.

Little update, took the Seca apart today, it is in pretty good shape as it is. One of the forks is bent:View attachment 27328
...put the forks aside for the time being, took the carbs off and set those aside, found that the front wheel is off an XJ400:View attachment 27329
Looks straight enough, I like the look of it, Will probably keep it, then took the rear sprocket off and as I am no expert I would like any of you to comment on it...is it
done for or is it good for a few miles still...: That sprocket, put into the language we use here in England, we would tell you that it's Well F#@ked! If I were you I'd change the whole drive! (Front and Rear sprockets, and a new chain!

Long story short...took the whole thing apart...so here is my mess:View attachment 27331 View attachment 27332 View attachment 27332 View attachment 27333
And then.....
Dude where's my bike?View attachment 27334
The plan is to dig into the engine, the carbs...and take it from there.Thinking of posting my progress on the engine on this thread(not to steel dynaglide's thunder) to give/get (mostly get) pointers as I go along, plan to do the same with the carbs.
That' about it for today, waiting on some oil seals to come in and pondering on an alloyboltz allenhead kit.

 

[Jeff0133]

Been pretty busy with my buddy's Seca bratstyle build but finally took some time to work on my project. So...Let's get an engine together...
When working( in this case rebuilding) on an engine, cleanliness is next to godliness. My wife was at work today so I used the laundryroom sink to clean my case halves with hot water to get rid of the sand from the sandblast.

Now that IS clean.

 

[Jeff0133]

Replaced the starter clutch bearing that was pretty much ruined from the sandblast.

Used a 29mm socket and an extension to tap it in. Went it and seated without too much fuss.

 

[Jeff0133]

Dont forget the little oil jet hidden under the bearing...it was taken out and thorougly cleaned

 

[Jeff0133]

Put the bearings back on the same place that they came out of, I tried but couldn't find those new anywhere. Put assembly lube on them.

Notice that I replaced the screws holding the baffles also...Stainless steal Allen head screws with anti-seize of course.My OCD is at it again...

 

[Jeff0133]

I couldn't find crankshaft bearing but...The connection rod bearings...
Bought xjr1300 bearings and they DO fit but...There is an oil passage on the connecting rod so there must be a hole in the bearing that aligns with it so I resorted to the faithful press drill.

 

[OopsAboutThat]

Awesome thread man! I'm loving all the DOHC engine/build threads going around here. Just a bit curious about the bearing shells from the XJR1300 you're using. In the DOHC manual it says that there are specific colour coded bearing sizes to match up with the crankshaft and con rods. Don't know if that's gonna cause any issues or not, but I read if they don't meet spec they can cause damage over time. Those cases are looking real nice by the way, I'm getting ready to mine as well. Cleaning is a REAL pain.

 

[Jeff0133]

I went with the calculation in the manual( the numbers on the case), and used the results to order the bearings, I measured the old ones vs the new ones, can't remember the numbers..But it was good.If i were anal about it I would have plastigauged but...Nah I trust my calculations and measurements.

 

[Jeff0133]

Back at it.

Put the rods on the crank.The Y mark has to be on the same Side for both rods as per manual, installed my brand new conrod bolts which have to be torqued on one single shot as per manual

 

[Jeff0133]

Dropped the crank and balancer shaft on the case

Align the two timing marks right now so you Do not have to take the shafts out latter.

 

[Jeff0133]

The Little oil nozzle comes out, sifted through an oring kit I have and found an oring that fits,so cleaned the nozzle thorougly with carb cleaner and compressed air and changed the oring.

 

[Jeff0133]

Oh and Will be using all new gaskets and seal for this...

 

[Jeff0133]

And that is what the upper case should look like...

 

[Jeff0133]

Everything gets a once-over with carb cleaner and then the rotating/rubbing surfaces get assembly lube

Like the shift shaft for example.

 

[Jeff0133]

When I come across a barely stripped JIS screw, it automatically gets replaced by stainless allenhead screws
