Jawritch Posted February 20, 2017 Report Share Posted February 20, 2017 I don't know if it's going to matter but it's from an auto so it will have a flex plate instead of a flywheel. The flywheel teeth are built into the torque converter. I should be able to get measurements to the flex plate and also to the "flywheel" teeth Link to comment Share on other sites More sharing options...
Brunet-Hemi Posted February 20, 2017 Author Report Share Posted February 20, 2017 is your flexplate currently installed? I'm not too worried about starter teeth, I'll probably have to relocate the started anyway because of the turbo so I can adjust for that. I suck at explaining things so paint to the rescue. Ideally if you could measure the distance (depth?, offset? whatever you want to call it) between the 2 mounting surfaces indicated. If your flexplate is still installed, then just measure what you can and let me know and I'll do some weird math or something to make it work. lol again I appreciate this.

Jawritch Posted February 21, 2017 Report Share Posted February 21, 2017 I see what you're saying. The engine is currently completely torn down. But I should be able to lay the crank in and get your measurements. Link to comment Share on other sites More sharing options...

Brunet-Hemi Posted March 6, 2017 Author Report Share Posted March 6, 2017 So I managed to get up to Toms yesterday. Took some measurements for how much fuel line I'll need and stuff. Got the adapter plate template finished up. All I need now is to sort out the flywheel and get those measurments from Justin. the flywheel might be a little tricky. The VW bolt patter is smaller than the bore on the Jeep flywheel. So it's not just a redrill scenario. I'll bring it to a machine shop and see what they can do. You can see the bit of silver through the holes in the pic. That's the Jeep flywheel. Link to comment Share on other sites More sharing options...
SQRLPWR Posted March 6, 2017 Report Share Posted March 6, 2017 looks great! how u gonna deal with the flywheel ? Link to comment Share on other sites More sharing options...
Brunet-Hemi Posted March 6, 2017 Author Report Share Posted March 6, 2017 I'm not sure yet. Still brainstorming. So far my best idea is to weld in a blank to make the bore smaller then drill the new patter on that. Here's a better pic showing the difference between them.

Lil'monster Posted March 6, 2017 Report Share Posted March 6, 2017 When you put a toyota trannie on the back of small block chev you use the chev flywheel and pressure plate and toy clutch plate. Can you use the vw flywheel and pressure plate and the jeep clutch disc Link to comment Share on other sites More sharing options...
Brunet-Hemi Posted March 6, 2017 Author Report Share Posted March 6, 2017 I think its too small the clutch wouldn't fit. I'll double check when home tonight Link to comment Share on other sites More sharing options...
Lil'monster Posted March 6, 2017 Report Share Posted March 6, 2017 They made an ax15 that went in a toyota I do believe . May be a smaller diameter? Link to comment Share on other sites More sharing options...
Powerram Posted March 6, 2017 Report Share Posted March 6, 2017 Maybe look into the 2.5L jeep clutch disk dimensions. Link to comment Share on other sites More sharing options...

Yeah they did. I saw my buddy's (out of a supra) the case was identical. The input shaft was different and different bellhousing. Not sure on clutch diameter though. 53 minutes ago, Powerram said: Maybe look into the 2.5L jeep clutch disk dimensions. Different input shaft. Otherwise that would probably work.

Brunet-Hemi Posted March 7, 2017 Author Report Share Posted March 7, 2017 Ok so I checked and the jeep friction disk is way to big for the VW flywheel/pressure plate, did some research to try and find either a smaller friction disk or bigger flywheel that would work and I've found nothing yet, going to keep looking though. I'm also going to stop by a machine shop tomorrow and see if they can add some material to the Jeep flywheel I have and make it work. one way or another I'll make it work. anybody know any good machine shops in HRM, Dave mentioned Rods. any other recommendations?

Also is the VW flywheel an imbalance or netural balance flywheel, I believe the 4.0 flywheel is a neural balance. Link to comment Share on other sites More sharing options...

An externally balanced engine has an imbalance machined into the flywheel and harmonic balancer at a specific point and specific amount. Mixing and matching imbalance and balanced parts has catastrophic failure on rotating parts like main bearings or worse broken crankshaft. Link to comment Share on other sites More sharing options...

Thanks, I googled it as you were replying. lol I had assumed all engines were balanced internally never really thought about it much. From what I found both the 4.0L and the VW TDI are internally balanced, so the flywheels should be both be neutrally balanced, by that logic i should have no issues with it.

Brunet-Hemi Posted March 12, 2017 Author Report Share Posted March 12, 2017 Perfect. Thanks man. just gotta wait for the flywheel to get back from Rod's then figure out how thick to make the adapter. And then I should be able to start putting this thing together. Link to comment Share on other sites More sharing options...
SQRLPWR Posted March 13, 2017 Report Share Posted March 13, 2017 Are they modding the flywheel or making a new one? Link to comment Share on other sites More sharing options...
Brunet-Hemi Posted March 13, 2017 Author Report Share Posted March 13, 2017 Modding, they couldn't machine the bolt pattern onto it so they are making an adapter. Basically going to bolt a plate to the back of it that has the right bolt pattern. Link to comment Share on other sites More sharing options...
