Vr flywheel

[VBRED]

I have a vr auto engine i amconverting to manual. The flywheel does not have any dowels to fit to the crank. Does it matter which way it fits up?

[moff_man]

yes, the bolts are drilled off center on the crank it will only go on one way


p.s its a pain in the ass to line up bye your self it gets heavy real quick

[bns 454]

from memory the bolts are staggered so it onley goes on 1 way. but i think on the early v6s the cranks are different auto/man and may need an adapter

[moff_man]

vn s1 had a 4 bolt crank, vn2 onwads had the 6 bolt im pritty shure, may need to confirm the bolt's not shure if its 6 or 8 bolt

So i have it fitted now so you say that it can only fit on one way and that has to be the right way?

I've recently converted a vr auto engine to manual, I hope you had the flywheel mirror balanced to the flexplate off the vr otherwise it'll likely be not the right external balance. I also had the PP zero balanced as well, man that was a smooth V6

That should be 6 and 8 bolts respectively!
His will have 8!

Important point!

The dowels are important and it's important to buy new bolts, not reuse the old ones from the donor car!

My understanding is that this only needs to be done with the ecotec cause it has a dual mass flywheel or something.

My engine did not come with a flex plate. Just snaped bolts in the crank.

Well sorry to start a debate, but "My understanding" on DMFs is that they were first rubberised to accommodate the Japanese market, DMFs make manuals "IDIOT-PROOF"! (With all respect - I'm not saying that all Japanese types are idiots, just something TOYOTA wanted to do first in JAPAN!) The DMF will easily compensate for an unbalanced FW.

Do you get it yet?

[Vr5speedv6]

All the versions of this engine( vn, vp ,vr and vs) have a different external balance, so I'd be getting a flexplate from a vr motor and getting the mirror balancing done. I'd also get the PP zero balanced while you're at it, these are often out by a noticeable amount.

vr book states bolts should be discarded and use new ones, both for manuel and auto, it also states bolts loose effective thread when undone and should be discarded.

quote from memory from when i did an engine change on my vr. its the same for vr -vs - vt - vx - vy - vz - ve

but you can do what you like at your own risk.......

Engine is from a VR the flywheen ik think is series ii vn i think. So to fix my vibration problem I will need to get a flyweel from the corresponding vr engine or a flex plate and get my flywheel mirror balanced. Who does the mirror balancing around Dandenong area? Yes I used all new flywheel bolts.

[Vr5speedv6]

Yeah mate get a vr flexplate and have the flywheel mirror balanced to it. I'd also highly recommend getting the pressure plate zero balanced, that way the balance should be spot on. I could recommend the shop I get it done on the gold coast, but there should be plenty of good engine builders down your way who could do it.

Yes I used all new flywheel bolts.

If you have already used them and intend to remove the FW for a balance, then back to the shop for 8 more new bolts, you will need to go!

[VBRED]

The problem has existed since the conversion. I called into a transmission shop yesterday and got a different answer. He said that the flywheels are the same from the vn series ii to to vr and they only fit one way. So that should not be the problem and keep looking.

Might be silly questions, but did you remember to install a spigot bush and how are the front engine mounts?

[VBRED]

The exceedy clutch kit come with the spigot bush so I definitely installed it. Mounts are new.

[v6lux]

OK, what about uni joints on the drive shaft? Are they new and installed correctly? What about shaft balance, did you knock a balance weight off by chance?

[VBRED]

Tailshaft was shortened new unis and centre bearings fitted and balanced. I am sure it is enginge related and not transmission. It is effected by rpm not vehicle speed.
