Stagea Brake Down

[rb30dett]

Our local bloke got a full reco set, both pulleys and belt for $225.

Thats a good price where from?

Engine is AOK. Seized idler pulley. $359 from Nissan.

Good to hear it is internally intact.

Got it from Spare Parts Solutions here on the Mountain. Kit has been express posted to where 17yo works with a motor mechanic.

phew ..... lucky outcome actually. Surprised valves didnt smash themselves to pieces.

glad you got out of it in the end.

Question : how many kms has the car done? was the stuffed belt in bad/worn condition or was it the bearings fault?

great to hear....buy that powerball ticket

AFAIK the prob was a seized bearing in the idler pulley. From what I saw, the inlet side has hopped six teeth, the exhaust side only one tooth. A new belt was fitted and the car started OK and was driven out to be fixed tomorrow when the new kit arrives. It is all very perplexing caus all the other threads I have read on this subject have reported severe internal bleeding. It must be remembered that the T/B did not break. It was partially laminated. I can only surmise that the ecu detected an abnormality in the "what?", and went into limp before any serious damage occurred.

Thank you Mr. Nissan.

I am off to the Newsagent tomorrow to get that winning ticket. Thanks Duncan.

The belt had been replaced at 105ks. Was a Gates. The belt was OK on the tooth side. The outside was laminated due to the seized bearing in the idler pulley.

Moral: When replacing the belt, replace the pulleys.

ahh there you go moving a few teeth is totally different to snapping entirely where the crank and valves can move independantly.

SR cams or not, surely the de motors have higher compression and therefore pistons protrude further into the valve area?

And yes.....always replace the idler and tensioner! This is far from the only motor this has happened to over the years Also, importantly, replace the stud that the tensioner attaches to, and the bolt that the idler uses, they can also break, particularly if poorly tensioned at some time in their history

[66yostagea]

When I see what is in the kit I will post it up.Hopefully the bolt bits will be in it.

its always advised to do the tentioners when u do ur timing belt so what happend dosent most people are to cheep but it certainly pays off

[Tangles]

having bearings, belts etc being replaced on the rb26 atm - track duties 3x per year only but no point playing Russian roulette

then again, also replacing rod bearings at same time, crankshaft being machined, oil return system, etc

[rb30dett]

Was it noisy before the failure? I have seen a seized idler bearing that made the belt melt and delaminate but the car was shutdown when they heard the sound so no damage. Anyway glad to hear it's all ok.
