hi guys,

so heres the deal i just got my b20 with built ls head back together and went to time it today heres what happened...
-aligned all my marks
-using brand new honda crv timing belt
-using semi new belt tensioner
-get the belt on, turn it over by hand and the belt jumps on the crankshaft pulley every time..

I can't figure out why it keeps jumping off the pulley so anyone who can help its very much appreciated!

** I'm also running a 19tooth water pump which is the ls water pump i believe**

 

did you try pushing the tensioner up to take up the slack and tighten it.

 

yes i already tried that mutiple times

 

double check the part number on that belt. maybe they gave you the wrong one.

 

pictures would help too.

 

yeah very doubtful that they gave me the wrong one, but a possibility i guess.

yes i'll post some pics tonight..

one guy told me i need a gsr timing belt??

 

when you tensioned the belt did you turn motor 3 teeth counter clock wise then tighten the tensioner? This is what sets the tension on the belt!

 

no I didnt do that!
i was unaware that was neccesary.
I'll try that tonight when i get home an leave an update

 

thank you so much bro!!!!
timing is perfect now

 

no problem...glad to help. do this on all b series and d series motors and you will be golden. still check the timing by rotating the engine 2 or 3 revolutions and check again.

 

good info sleep! I'll remember that also, may explain why my LS ran like poop!!
