EA82 Broken Timing Belts????

Wraith · Post by **Wraith** » Tue Oct 10, 2006 8:38 pm

Hello everyone.

Before i drag out all the tools, and blunder around with my wifes 1988 carby L-Series, i would like reassurance from some members here if my diagnosis is correct.

She was driving home tonite, when she felt a slight shudder through the steering wheel, then she smelt what she describes as burning rubber, then all of a sudden all drive was lost, and all the lights on the dash went on.

She coasted to the emergency lane, and called me. I couldnt get it to start either. No coolant loss, no oil loss, no over heating. All appears well.

When i try to start it, it sounds like the starter is just free spinning if that makes sense.

So, bearing in mind that i am a mechanics elbow at best, has a timing belt fubared??? or something more sinister happened???

I can confirm no fluid leaks from anywhere.

So before i start swapping coils, dissy caps, and plugs, and leads, is it the timing belts??? They were done at 245,000km. It just clicked over to 300,000. I would have thought thats early for timing belts.???

We are a bit cranky, as its cost us $143 to get it towed home. Any help would be appreciatted.

thanx in advance.

Does the engine actually turn over when you crank it Wraith? When my mates L Series died from a broken belt I saw the dizzy wasnt turning when he cranked it.

Hey Mark

I think the replacement intervals for timing belts on them are 60,000, but i cant really remember, its fairly short anyway. Sounds like a break - when I broke mine the oil light came on momentarily before the engine cut out. The easiest way to check the belts would be just to whip off the plastic covers - it wont take long - or you might even be able to see through the inspection holes that - just remove the rubber grommets and shine a torch through. Sounds like a broken belt to me though.
Cheers, Timmo

Yeah sounds like a timing belt, check your bearings in the tensioners when doing the job, if you replace the bearing only, do it with high speed bearings, I didn't and had to do it again within 3 months

. A lesson learnt! Done mine from reading a Gregory's manual and had no hassles.

high speed bearings ? got some names or part numbers handy ?

NTN BRAND; 6203LLHCS25/L283QP

Ok I put in one bearing which failed within 3 months. So I rang the bearing shop in Dubbo and they said about using "High Speed" bearings, so I used the above number that they supplied and they are still going strong 6 months later, no problems yet.

Not sure if "High Speed" is fair dinkum or bullshit but I can only go on what I have been told by the bearing shop.

While they are working then I am happy to believe them, I guess someone smarter than me will point it out if I am wrong.

Hey Wraith,

Sorry to hear about your wife's subie. It does sound like a cam belt to me. As said before, if its a left hand belt the rotor button in the dissy won't spin, but if it was the right hand side one the engine would run but very poorly.

Cam covers are the go as timmo said, or the inspection holes.

If it is a timing belt, you should beable to remove the airconditioning compressor and alternator as one assembly (saves alot of time), you just have to find the right bolts: One behind the alternator on top of the head, one on the inlet manifold, one under the air compressor near the water pump from memory, don't have to take it out because the hold is slotted (has a spacer in there too) and there may be another one under the assembly, between the compressor and alternator, could be the belt tensioner bolt.

Hope this is of some help.

Good luck.

Ok guys I have a question.

No doubt be a stupid one!:???:

When a timing belt goes on these flat fours do you destroy your top (or should that be side) end??

Please go easy on me. I havent really researched these things much.....................yet.

Very interested to learn more. Have been reading heaps (behind the scenes). Nice site.

I didn't on the EA82 when I did the timing belts.
I got the right hand one out by a long way cause I lined the crank up on TDC and mate popped the belt off when the cam spun around from where it was without me realising it.

Put it all together with new belts and it ran like a sick duck blowing air up through the carb etc.

Had a look and ended up taking the cam cover off and setting at where I thought it should be and the thing now goes better than before.

So if a belt breaks then no it shouldn't bend valves but also mark the pulleys and case before removing any belts, Even if the timimg marks are lined up.

My vehicle rolled on with it still in gear and done no damage to the valve train etc. It was also turned over several times after coming to a stop to see if the dizzy was turning. Both times I done the belts it was because the idler bearings seazed, one due to old age and the other due being the wrong type of bearing. Good luck, Toby

EA82 is non interference motor, so no it won't stuff your valves.

Standard timing belt replacement interval is 100000km or every 4 years, whichever comes first.

If it went well before htat I would be looking long and hard at the bearings / tensioner.

Sounds like my engine when it done the same thing.

Yeah, thats how the bearing shop described them?

No problems with my engine.
