Default V- speed conversion

I am converting my V-spec .21 over to a Speed crank, rod, piston&sleeve. however i was not aware there was a thermo insulator stuck in the engine block.....I did not see it when I disassembled it, I thought it was attached to the carb. Well anyway I heated the case w/ a heat gun to change out the bearings and apparently crazed/overheated/made it brittle, I had a heck of a time getting it out. It's not gonna go back in. I've ordered 2 new ones as well as the rubber coated washer at the bottom of the intake manifold. What is the proper way to remove and install them..... should it have stuck to the carb when I pulled it out. Did I overheat the engine while driving and cause this??? Did I overtighten the pinch bolt???

I didn't know vspuds had a temp isolater thingy between the carb and block?? You probally cooked it with the heat gun.

The bearings are simple enough throw the whole block in the oven heat to 350, push the bearings in.

Try u-tube .... rc nitro bearing replacement w/ David Mills part 1. I think he owns Boca Bearing and his part 2 shows how to do it w/ a tool. He used a hot plate ... I used my heat gun ......not one for rc but one that is for stripping paint.... I used a temp gun and got it up to about 245 because it wuold cool down quickly and I was compensating for the time delay.It went very smooth.

I ordered mine thru HobbyTown..... Should be here Tomorrow.... Imaxx posted A-main has them and they gave a link (cool) 13.49 (ouch). Should mine have stayed attached to the carb when I pulled the carb out???? or did it stick in the block from heat or overtightening???? BTW Love my upgrade graphics!!

it should stay attached the carb wen pulling it out of the case but sometimes they do stay in the block. i usually just use a small reamer to pull it out

Should I use adhesive on the new one ??? Or was mine over heated by lean condition or possibly overtightening the pinch bolt?????

i would not use any adhesives unless you are talking about your engine sealant around the actual neck of the carb then the insulator over that. i would not use anything else tho. the same thing happened to me on my speed, and what it looked like had happened to me was that the pinch bolt got over tightened and then just a tad bit out of round thus not allowing it to pull out smoothly. have not had a problem with the new one doing it so that was my conclusion.
good luck
