Car Forum / Honda Cars / August 2006How do I properly install timing belt, balancer belt on H22A Engine? Please Help
Does anyone know where i can find more information on changing the timing belt(possibly with pictures) on an h22 properly. There are two main things i am concerned about: What is the best way to remove the crankshaft pulley bolt? Once i remove the timing belt, what happens if the crankshaft or one of the pulleys is rotated a full revolution without me noticing even if there is a mark, do i just realign the pulley with the mark or how do i make sure the it is aligned? to my understanding the below procedures are the correct procedures to align the first piston to TDC and install timing and balancer belt. 1. align the cams with the word top at top, tdc marks aligned with cylinder head upper surface 2. align the groove on front balancer pulley with oil pump housing 3. align the rear balancer pulley using the maintence hole with a bolt to 74mm scribed line 4. turn crankshaft pulley one turn counter clockwise. If anyone has anything else i should know that would be greatly appreciated. thanks Matt > Does anyone know where i can find more information on changing the > timing belt(possibly with pictures) on an h22 properly.

Have a read through here: http://www.tegger.com/hondafaq/faq.html#engines Then save yourself a ton of grief and potential damage by buying a factory shop manual here: www.helminc.com You can find used factory manuals on eBay. Forget Chilton/Haynes, etc. They are useless for this sort of thing.

'Curly' i already have the engine out, that was the easy part, now i have the jdm h22 on my engine hoist and have heard of the autotensioner failing. how do i remove the crankshaft bolt when it is out of the car? should i set the engine on the ground? haven't tryed yet, just want to be prepared. obviously the special honda removal tool in the previous links is the best way to go other then air, but the engine on a hoist may present a problem when trying to break the bolt loose. i have both the service manual, swap guide and the chilton manual, but am sure there are others things i should be aware of when working with the timing belt. i work with networks and computers so the wiring and electrical is second nature to me, but the machanical i want make sure i do correct. matt > > Does anyone know where i can find more information on changing the > > timing belt(possibly with pictures) on an h22 properly.

Please tell us what year / models of CAR we're talking about, so everybody can _picture_ this operation . . . 'Curly' yes it has an auto tensioner, i should replace it with the manual tensioner, correct? > > i already have the engine out, that was the easy part, now i have the > > jdm h22 on my engine hoist and have heard of the autotensioner failing.

Even a stout electric job may do the trick. Honda is backwards from toyota. A yota, you can use the starter motor to knock the bolt loose. But not so on a honda.. So really, unless you like lots of brain damage, I'd use an impact if at all possible. Both taking it off, and putting it back on. . It needs to be torqued up to at least 85 ft lb's or maybe even more. Check the manual... > > > Once i remove the timing belt, what happens if the crankshaft or one of > > > the pulleys is rotated a full revolution without me noticing even if > > > there is a mark, do i just realign the pulley with the mark or how do i > > > make sure the it is aligned? Draw painted marks BEFORE you take it loose. Also note all the proper factory alignment marks. You can't even be one tooth off when you put it back together. It MUST be perfect. No slack in that regard on the usual honda.. Also, yes you need to change the tensioner. Also, you really should change the water pump while you are in there. All those parts have the same appx lifetime, and you don't want a repeat of all this fun. Also, check to see if any oil seals should be replaced. Now is the time to do it.. BTW, when you get it installed, rotate the crankshaft a few times to make sure that there is no interference. If you feel anything at all hitting, take it off and start over. If the belt is on wrong, and you start the engine, it's pretty much toast. You'll have bent valves, and all other kinds of wonderful problems. So be totally certain it's right. MK |
