had a b18c jdm swap done on my 98 civic ex coupe done last week,
with stock mounts.. ran smooth.. no vibration!! at idle or taking off
did not have a/c belt hooked up was waiting on 99 crv bracket..
compresser was hooked up to b18 bracket with 2 bolts..
any way, 99 crv bracket came in, mechanic put the belt on
a/c works great.. notice vibration at idle and taking off..
so much , rattling door panels, got home check lower mount coming off a/c bracket seem ok !!! by the time i called mechanic.. shop was closed..
could a/c compresser be causing that much of a load on motor to cause that much vibration
any one run into this problem?? help!!

thanks in advance

 

how many long bolts do u use to secure the ac compressor and also. do u use the ac bracket mount that goes under the chassis. do u use tranny torque mount? how are the condition of the oem motor mounts?
i had the same problem before.therefore i replaced all the 5 mounts.

 

4 bolts to secure compresser... on to bracket
99 si tranny bracket
stock mounts were ok .. like i said ran smooth before a/c bracket and belt
belt put on.. even with a/c compresser off still vibrates

 

and yes,, i used a/c bracket mount

bad or excessive vibration is caused by bad or worn motor mounts. do u know how old are your stock mounts? and also any crack or damange to them ? include ac mount and tranny torque mount

 

they are original mounts... 10 years old
mechanic stated they were ok,,
whats odd is vibration started after a/c work..
maybe coincedence,
did open it up a few times maybe ripped one enough where, when extra load of a/c compresser caused bad vibration

 

ok, guys found out it was 99 crv a/c bracket...........
put swap bracket back on
no vibration!!
having a/c lines made up!!
for swap compresser...
anyone need crv a/c bracket!!
