Title: replacing intake rubbers and cleaning TB's
Post by: s1120 on September 21, 2019, 05:31:12 PM
This off season Im going to replace the intake rubbers on my 02 stone. I also want to clean the TB's while im at it. Ive searched to see what's involved but I have not seen anything. Is it just cut and dry to replace them? Any thing waiting to bite me when I get in there?

Don't know about the Cali, but if it's anything like the 2TB small blocks, you'll need the hands of a pixie & the strength of Hercules. Just don't mess with the sacred screw.

It's a lot of twisting and cussing.

At least on a small block, it really helps to heat the intake runners.   Much much easier to manipulate them when pretty hot.  I used a heat gun and gave them a good working over. 

Silicone grease on reinstall.

Ya..  I was afraid of that...  Kinda looked like it might be... but I have seen no posts on it, so was kinda hoping it was simple..

What Smith said-with lots of cussing!

On my '04 it was fairly easy to replace the rubbers.

Loosen the ones to the airbox and slide the tubes back into the airbox to make room. Some twisting of the tube and maybe a bit of lube may help.

Now is the tougher bit IMO. Getting the TB's off the head side rubbers. Some can pull them off and install while still bolted to their brackets. I found it easier to un-bolt the TB's one at a time and do that side rubber, bolt the TB back on but leave the clamp for the rubber a little loose and then do the other side. If the rubbers fight with you, try a small amount if lube to slide them on.

A note on the rubbers. IIRR, the boots have ribs molded into each end. IIRR the ribs have different spacing. One end is for the head and the other for the TB. At least that what they did on my bike.

Slide the airbox tubes back in place, make sure the throttle linkages are not jammed and your done.
