Can i do that... Won't it give up with heat and then maybe its particles can create some trouble in the housings... just an assumption... i am a frist time rebuilder.. If this is too stupid a question... https://www.nopistons.com/forums/pub...#>/biggrin.png



I would love to use super glue thats the easiest way...

The super glue is there only for assembly.

It breaks soon after you complete the rebuild.

Some of them break when you crank the engine over by hand for the first time.

It's a bit unnerving when you hear the *tink* when the super glue bonds break. https://www.nopistons.com/forums/pub...R#>/unsure.png

when using 2 piece seals I did what kahren said.



I didn't have any problem that way. Work really good and 2 piece ended up being A LOT easier than 3 piece b/c of that.

Thanks a million guys... Used very little superglue.. it worked very well for me... Installation became very easy.. Thanks



Ok one more question..The first rotor is supposed to go in one apex seal facing twelve o'clock... i did that... then after the intermediate housing the eccentric shaft has to be moved to the six o'clock position and then the rotor has to be installed in the six o'clock position...



I do remember that the second rotors one apex seal was facing the six o'clock position but i do not remember if the eccentric shaft was moved to the six o'clock position... Can that happen.. I mean is it possible that the rotor was facing 6 o'clock but the eccentric shaft was not... https://www.nopistons.com/forums/pub...1047683664.gif I have a doubt because i had to reopen the housing so many times because of the seals poping off.. My mechanic is sure we did it...



I am thinking of taking off the side housing and confirming...



Have checked the compression on the stand.. In three complete rotations it does make 6 strokes or chubs.. Is that an indication that everything is ok inside??



Thanks for all you help guys.. really really appreciate it..

You pretty much cannot install the rotor 'wrong' especially the rear one, after you've done the front (obviously).

So long as you didn't _force_ it in i'm sure it's fine.



And yes so long as there is 6 even(!!) pulses it sounds like its good. https://www.nopistons.com/forums/pub...IR#>/smile.png

thanks White_Fc .. i was sooo scared.. we did not force the rotor in..



Also it is giving 6 good pulses does that mean that the car would start ok once the engine is installed....



Sorry for silly questions.. First time rebuild...

White_FC 05-07-2004 08:56 PM

Basically no, it doesn't mean it will start right off the bat.



I know mine didn't, I had to tow start mine...

Now after 50kms on it it starts first crank just about and runs perfect.



Just make sure your timing is spot on before trying to crank it forever https://www.nopistons.com/forums/pub...IR#>/smile.png



And if worst comes to worst just tow start it.
