Ebay timing chain kit
Hi,
I am rebuilding a 1NZ-FE engine, fitted on a EU Yaris TS, and I have some issues regarding the. Sprockets from the timing chain kit that I bought. More exactly, the sprockets are somehow a bit smaller, and the interior fitting guides are a bit larger, so the sprokets are not fixed, as the originals are. Is this a normal issue in this kind of kits? I don't know what to do exactly, as I quite struggled to buy a timing kit that had all the 3 sprockets included to observe now that they're not good. My mechanic says that he would use the old sprokets, even if they're a little bit worn, they're better than the new ones... Has anyone had this kind of issue before? Thank you! |

No but I agree with your mechanic.

How many km's on you old chain? The chain won't wear out the sprocket until it is really worn and been used that way for a while. I'd do what your mechanic said, chances are the sprocket isn't worn in too bad.
At least that how it works when it comes to fixing road and mountain bikes in regards to their chain/sprockets |

Ok, the problem was that the original sprocket was having a deeper fixing plate, while the new one had a profiled one, so it pushed the sprocket further out. Are there different sprokets for different years? Like, is it possible to have different camshafts?
The only ideea that came through my mind was that there are different stockets for normal 1nz and prius 1nz. The vvt-i sprocket was fine though. Here are some pics: The chain was quite worn as I believe it had been driven without oil; the oil pump pieces were having very deep scratches, like they moved without fluids. The whole engine was very worn (pistons, cylinder walls, etc), and for only 142.000km, going without oil would be the only explanation. Anyway, almost everything was changed with new pieces; I've bought an ebay engine shortblock, remanufactured with forged internals (Arias 9.0 pistons and Molnar rods), and after several hours I realised it's been redone by TBR, so, suddenly, I panicked :)))) Now, I'm very eager to see if I've bought a junk, or not. I'll keep you guys updated ;) |

During my time as an engineer on various ships trading around the great lakes, as far as I can remember, in almost all power-trains, a chain will stretch far before a sprocket will wear-out.
Here's an excerpt from one of the large bore Sultzer engine manual: With regards to the chain: Quote:
