WTB - Space Bug Jr. crankcase

Just the crankcase.

We bought one that was supposed to be new but turns out it had been run and there were toolmarks on the drive-plate. When I changed the drive-plate I forgot to insert the "counter-piston" (a bolt we made for this task) before pressing with a vise  

If we cannot find a crankcase we will simply sell the parts by themselves.

Got one it had a broken CS when i got it the case looks to bee in good shape ,, IT NEEDS CLEANING !! Anyway i will let you decide if it is something you can work with (((( What color is the one you destroyed ?? LOL don't take it too bad Stuff happens......




$20 U pay shipping O hea u get the whole thing!!

Would need a lot of cleaning lol. The one we got has a "clear" tank and came in the OEM early-edition bubble case, replete with wrench and instructions. It's a really nice engine and probably was only run for a minute or two.

this is the best i have now

they could stand some tlc.. Yeah!!!

Nice

What do you need for the crankcase?

Bernie , let me clean the one at top in question and show it to you again But ; i would bee 30- if i have to take the time to clean ! The four are NOT for sale at this time . Eric

Yes Eric, I went by the premise that you were simply showcasing your collection

Please wait with the crankcase as a member has offered a NIP one for Space Bug and, when I am back in the office on Tuesday, will check if it is identical to the "JR" one; in which case I do prefer to take the new one.

Happy New Year everyone

Bernie, Can you explain what you did? Did it destroy the crankcase? Thanks, Andy

Here is the clean up ;; seems the lf strut is of corrosion ?!?!?.. i am sure you will get what you need to repair the SBJ '''''.....




Thanks !! Eric

Basically, because I forgot to insert something into the crankcase, against the face of crank, I pushed the neck of the crankcase right through the crankcase. Have assembled 1,000's of engines but was yacking on the phone and forgot that important step.

Apparently, the crankcases of SB & SB Jr. are different.

Yes, The SB Crankcase has the top mounting holes drilled so you can insert the mounting screws from the front. The SB jr does not, because the mounting screws go in from the back. Andy
