Cambelt snapped

#1 Post by Thetwisted » Tue Mar 05, 2019 5:58 pm

Hi people looking for a bit of advise.

So the belt snapped on my 216 dohc Honda engine (94), ive only owned it a few months and im gutted, i read somewhere something about non interference engines, is there any hope of sticking another belt on and off she goes or is it a strip down mega money job?

Cheers
Jay

Good news, off memory i'm sure the honda engine isn't an impact engine so should just be a case of new belt away you go.

Were you driving when it let go? did it just stop or was there a loud bang and the sound of poppet valve hitting piston crown? :scared

I have the Honda D16 engine workshop manual some where, I will try to dig out later tonight.

It's certainly worth the cost of the belt to give it a go

Thanks for the replys.

I was doing 70mph & it just died no bangs or pops.

Worth a new belt with CORRECT alignment of both cam shafts and the crank shaft.

Other than that, it's head off and have a look. Not a small job and I'd only really entrust it to a decent engine specialist who does honest, fair work for fair prices. Even if that was just a diagnosis and estimate type thing.

Not sure how easy repair parts are to get for the DOHC - it might be that you have to approach a specialist engine rebuilder to be able to get hold of the parts.

In contrast, the SOHC engine is basically a D16A6, which was in the Honda CRX MK2 88-91. Ebay is full of off-the-shelf rebuild kits that contain everything including valves and pistons from the US. None of the parts fit a DOHC engine and I'm not sure where you'd go to find them. The D16A8/A9 WAS also used in the CRX, but it wasn't experimented with as much as the SOHC and I'm not sure the rebuild kits exist. An engine rebuilder might be able to get you a parts list of what you need and I think they have some privileged agreement with the manufacturers by which they can more easily buy what's needed.

Having said all of that.. I've found a full set of valves, springs and other hardware from a 47K D16A9 engine for £45 posted: https://www.ebay.co.uk/itm/Honda-CRX-16 ... 3135822840

I'll have a look later and see if I can get you some part codes and equivalences... You'd potentially need pistons and valve seals too...

Would a look down the plug bores with an endoscope device save taking the head off only to find fortune had been smiling?

Remember this happening a many years ago to someone , the cause of the failure was water pump not the belt , The water pump seizes and that strips the teeth on belt.
so examine belt for striped teeth , i always change the pump when doing a cambelt change ( maybe because i run a alfa ).

use the endoscope device if you can good idea :clapping , fit a new belt and turn it over slowly by hand (plugs out) to see if you can feel any interference or obstruction.


the guy i no whose belt went got a way with it :clapping , so fingers cross and all the best and if you need a haynes manual i have got one you can have .

hope all goes well :D

^^^ Very good advice. Wish I'd supplied it.

PS. Now I know why garages insist on changing the water pump when they change a cam belt.

For the D16A8 engine:

Pistons

13010-P29-000 Piston set (Nominal/standard size)
13020-P29-000 Piston set (Oversized 0.25)
13030-P29-000 Piston set (Oversized 0.5)

(They're basically Honda "P29" pistons which you can look up on Ebay)

Piston ring sets

13011-PM6-003 Ring set standard (Manufacturer: Teikoku)
13011-PM6-004 Ring set standard (Manufacturer: Riken)
13021-PM6-003 Ring set 0.25 oversized (Manufacturer: Teikoku)
13021-PM6-004 Ring set 0.25 oversized (Manufacturer: Riken)
13031-PM6-003 Ring set 0.5 oversized (Manufacturer: Teikoku)
13031-PM6-004 Ring set 0.5 oversized (Manufacturer: Riken)

Valves

14711-PG6-000 (intake)
14721-PG6-000 (exhaust)

Valve seals

12210-PT2-003 Valve Stem seal A (Manufacturer: Arai)
12210-PT2-004 Valve stem seal A (Manufacturer: Nok)
12211-PT2-003 Valve Stem seal B (Manufacturer: Arai)
12211-PT2-004 Valve stem seal B (Manufacturer: Nok)

There are probably a few more parts you might need, but this should help an Ebay search.
