u used the pulley from the FU engine or bad one ?

the pulley that come with the block. but the damn thing jump back out again.

Your mechanic probably didn't bolt on the pulley tightly enough. Check another mechanic:

well i was thinking of doing that and a man really tell me check jason so i think i'll check him out tomorrow. but d mechanic tell me he use de air gun to tighten it so me ain't know nah. but thanks a a lot crazymofo.

air gun he a sure quack

all these things have torque specs

out

check jason he go link you only home the other guy did not mess up the crank

i hope so too.

There's a pulley lock to use when tightening the pulley. the pulley thing is a virus the civics came with. Autonation sells it.

If it jumped out again, surely there is a small crack by where the pulley key sits and the pulley is backing out again. Which means you will need a new crank or a next new engine. Sorry bout that.

ooohhhh................so that's why half the D15s in some FU places missing the pulley. always wondered why, even though its not bonded rubber like some toyotas and suzukis etc.

hoss..i had dis problem..it d friggin worst..had to change d whole engine cuz it mash up d crankshaft..make sure he take off all d belts and puts it on straight wen yuh doin it...da cud cause it to wobble an loosen..gudluck fixing it brother..i can honestly say i no wat yuh feelin

me too, the key gave way and mash up the teeth in the pulley that mounts to the crank. if u lucky enuff and ur crank still good, just get a light weight pulley. if not, see if u can find someone scrapping a d block and get the crank. i had a vtec engine, ended up buying a non vtec block and swapping it in. performed nicely still too.

^ worse advise a light weight crank pulley

light pulley can cause the crank to break .. honda made it with a damper for a reason

keep stock crank pulley other such as PS, alternator could go light

Had this same problem on my d15b hatch 6 yrs ago when mechanic changed timing belt.Didnt lock it down tight enough.Next thing pulley eat way.Good thing i dont used to drive it regular.Only damaged the pulley.Got that rebuilt and got a new key and was good to go and this time mechanic used locktite to secure it and good ever since.
