Som gjerne noen har fått med seg, klarte jeg ikke å få endeslark på veiva. Grovmål viste at anleggsflate på svinghjul bunner lageret 0,5mm før wedgematen er trukket helt inn.
Plukket fra hverandre motor, målte lageret i går. Joda, det er 27mm på utsiden som det skal være. Så finner ikke umiddelbart noen feil.
Hender det at det midtre lageret tar i veiva før veiva bunner i thrustelageret?
Her er dialogen med DPR: (Må leses nedenfra og opp, kopiert fra Outlook)
I appreciate you are level with me.
I'm tearing the engine down.
Sad because I thought I had it under control and the engine looks great ☺️
But better safe than sorry
Thanks

Some thing is NOT right... some times the engine block have more material ( this is a common issue with some engine blocks specially if is an after market) inside and don't allow the crankshaft to move free from side to side
The amount you want to machine is way too much.
Problem is that this motor is all ready complete, normally a motor like this Must be PRE-ASSEMBLED to make sure that all parts fit and feel just fine
End play must be done at all times when there is No pistons or any cylinders mounted for the same reason.
I just trying to help to my best, if you want to machine the flywheel so you can have room for shims is up to you.
The other option is to take the motor apart and measure with a filler gauge to see exactly the distance between bearing and shims.
This must be done with out removing the flywheel as is now.
Let me know

Hi
I have already used correct shims and torqued it to 700nm but the crank got stuck with no endplay.
That is why i measured it. Can i machine down bearingsurface on flywheel 1,5mm?
Thanks

I think using a caliper is not the right tool. also if crankshaft is not push all the way to the back you can not get the right numbers,
Thats why we pre-set endplay by torquing flywheel with the bearing on crankshaft, and checking the gap between bearing and flywheel.
Also the right bearing to be use is just the regular bearing for type 4 on the # 1 main bearing there is no need to use a split bearing, those are for flange crankshafts, but if you have that is fine, basically is the same.
So just install your flywheel and give it about 500 to 600 ft/lbs of torque, also make sure that end play is right.
Thank you

Hello Jose.
Please see pdf attachment for measures.
I used a caliper to measure, but it was difficult to measure exactly.
I belive I also used these bearings:
http://www.piersideparts.net/mm5/merchant.mvc?Screen=PROD&Store_Code=VWP&Product_Code=JCVDP021&Category_Code=EBEARINGSAre they thicker/wider?
Yes this is my first wedgemate project.
Best regards

Emne: RE: Flywheel clearence issue
Hello Jan
How did you measure the distance on the crankshaft and the depth on flywheel ?
Please tell me the sizes you get on both pieces.
Its this your first wedgemate project?
The crankshaft thrust is done to be used with regular main bearing
Please let me know
Thanks

Hi
In august 2014 i bought a cranckshaft from you via Piersideparts.
Im about to finish the engine, but have some clearance issues with the flywheel.
I bought the 84mm 2”Chevy balanced 8 dovels heat treated with wedgemate and all 411 mains.
On the back of the flywheel it says: 0,030=0,006 Translated to metric it should be like 0,76mm with spacers gives 0,15mm clearance.
But when I measure the cranck compared to the surface of the bearing, and the depth on the flywheel, it seems that I have to machine down the flywheel app 1,5mm to get 1mm clearance to shim up.
Could it be that the different bearings vary?
I did use a HD split front thrustbearing for flanged cranck.
I am just a bit worried if something else is wrong, so I hope you can tell me this is a common problem. (If it is)
Best regards
Jan Olav Hansen
