So almost got my 306 V6 conversion running but having another issue. not in a 205 but it's info on the V6 engine specifically Iam after.
Basically the engine isn't turning over.. the starter is firing but it's like engine is seized. (Which damn hope it's not!)
The engine I fitted was from an auto but obviously I fitted a normal v6 manual flywheel.
I didn't fitt any spacers behind flywheel as wasn't sure if needed them and am now suspecting it's bolted up tight to the engine :(
Could someone with service box please get me a picture of the v6 manual flywheel setup please or tell me from their own knowledge if and what spacers I might need between flywheel and engine.
Don't want take box off again if not needed as all running gear bolted on and tightened up now :(
Thanks in advance

no spacers between the crank and flywheel, only under the bolt heads.

 

pull the plugs out and see how easy it turns over with a spanner on the crank pulley.

Inlet off and new plugs back out and I can't turn it over.. I've heard they are a pig to turn over like this anyway but I'm worried if I try and harder il round or snap the pulley bolt :(
Iam sure when we put Flywheel on we had wedge it so could tighten the bolts so it must of been turning to start with.
There's only one other thing I can think of and that's a bolt or something has fallen in the box and is jammed in-between flywheel and box maybe?
Really am stuck on this one. I never thought to turn engine over while out so can't say 100% it's not seized but was sold it as a known good engine apparently. And as said the flywheel had be wedged to tighten bolts so must of been turning.. ... Any ideas guys?! :(

Did you take the bush out of the crank? Auto's have them manuals do not, Been years since I took a flywheel off so look at service box and see what's listed on there

Yes exactly thankyou mate. Altho now Abit confused... Aren't 11+12 just the one piece flywheel.. surely it's not a separate starting ring that's part of the flywheel??
If not I'm missing a piece?!?! :S

Yes I saw that... The manual box was a pig to get on... Is that bush pressed into or around the shaft input hole? Could it be seizing the gearbox shaft/crank(engine) all solid?
If so looks like the bloody box does need come off then :(

Ring gears are normally a separate circle of steel that is heated then fitted to the flywheel and shrunk into place , the service box diagram is just showing a replacement ring gear in the unlikely event that you need to change it . I believe the bush that Miles is talking about might be number 11 in the top picture , some cranks have a bush or needle roller race that the gearbox input shaft runs in .

Yes that's what I thought about the starter gear and yes I saw the bush on picture. As said the box was a pig to fitt on the floor. Could this bush be jamming the whole lot up tight because the flywheel is tightened up against it??

yes, also if you missed out number 13 'support washer'  on the manual flywheel diagram, the bolts may protrude out the back too far, not certain on this as it has been so long since I put one of these together.

Had my defender similar situation, wouldnt turn over when changed clutch, too much pressure from box on the clutch and it basically seized solid. Box off sort clutch splines and all was good.

thats a bummer, did you get as far as clipping the release bearing into the pressure plate too?

oh, its a pull clutch but comes as 3 piece and you clip the release bearing into the pressure plate, its a one shot deal.

I've reused the clutch that I got with it as was apparently quite new. It was a f***er getting the box on and the arm in the bearing. Same issue as with the VTS box (any pull clutch) can be a pig especially when the v6 box weighs as much as a baby elephant :s

When you take the box off you will have to either buy a new release bearing or it is sometimes possible to split the release bearing by removing the split ring/circlip thingy. Very fiddly job though.

 

As a side note, there is a username and password for servicebox in my signature just at the bottom of my post \/

O really?! I've always just struggled like hell the wriggle boxes on while fiddling with the clutch fork to get it aligned and slide in as box slides in. Is a pig but I've done loads like it.. I've brought several new 3 piece (described clutch's and usually valeo ones) in past but they have always come with the bearing already fitted to the pressure plate never separately?!
No wonder I always struggle!!
Got the box off in no time last night then spent a few hrs trying get it back on and it still isn't!! Hopefully will get it on tonight and see if it still turns over, as soon as box was off the engine turned over easily. There was NO bush in the end of crank it was all identical to my manual engines crank. I'll report back once Iam sure I've solved the issue...
P.s thanks for the login details Goliath I hadn't seen that sign before as was using the mobile version of site on my phone and doesn't shows sigs!
