manual conversion URGENT!!

[IhateRICE!]

hye guys i'm planing on converting my series 1 VN commodore auto to a manual and i've found a series 1 VN manual is it possible to just swap gearboxes or do i have to change engine aswell??


Cheers Guys

im about to do the exact same thing, you need either a special flywheel or a crank adapter from CRS.

[LowVp]

if its a series one engine then you will need to change the engine or the crank, S1 auto cranks are 5 bolt and the manuals are 6 or if CRS do make a 5 bolt flywheel that would be the cheaper way out

[mischa]

all VN S1's autos and manuals are 6 bolt... its in the manual.

thats what i thought. i alway's thought it was where you went from a s1 to a s2 gearbag there were issues.

[mischa]

yeah S2 are 8 bolts. The Castlemaine Rod Shop theres the site, heres the direct link to what you want http://www.rodshop.com.au/catalogues...alAdaptors.pdf, either the top right flywheel ($615)or the crank adapter($338) you can use either one. ill be ordering mine on monday, ill be posting progress in my ride once i get started on it.

is there any chance of just swapping the bellhousing? sounds a abit stupid i just bought another car worth 900 bucks and i only bought the POS for the gearbox so i just planing on swapping geaxboxes but no holden had to make it difficult

[IhateRICE!]

or why can't i just use the flywheel from the donor car ( manual ) and use it?? i'm just trying to get this done quick and cheap so

The s1 manual and auto cranks are different - both are six bolt, but vastly different in the flange size, which is why CRS do an adaptor as mentioned previously.
your choices are to use the CRS adaptor (expensive), use the crank from the donor car along with new bearings, gaskets and seals (probably just as expensive) or use the manual s1 motor from the donor car (more affordable?).
Just remember that the flywheel bolts are "torque to yield" (use once only) and will need to be replaced.

ignore that last post mind block

cause the crank is differnt.

i got my doner car for $900 and i have to buy the cank adapter (or flywheel, i chose crank adapter) and i new clutch (cause i need a new thrust bearing). Swaping the engines is a matter of witch ones in better condition? The auto i gots only done about 187,xxxkm so i wouldnt swap it with the manual 300,xxxkm its worth it to get the adapter. Changing the cranks is a big job.

[IhateRICE!]

ok just some more things i need cleared up i planing on just getting the crank adaptor so that get's bolted to the auto engine and then i need to get the manual flywheel is that correct??

[mischa]

im pretty sure thats how it goes, ask once you ring them up to make sure tho. ill be ringing tomorrow and ill ask.

[IhateRICE!]

if thats it then i'll have a smile ear to ear. heres the other thing can these adaptor work in reverse like manaul to auto my plan was to take what i need and replace it into the donor car and then sell it off so. if so i'll get one made up at work

you sure on that, no mention in the gregories about it. there only torqued to 90nm

the adapter it self cant be used in reverse (i think), manual - auto, but as in how to actually get that done i got no idea.

[IhateRICE!]

i assume that the bolt pattern on a manual crank is wider? and the auto bolts are closer to the centre?? so i guess the plate goes onto the auto crank and then the flywheel gets bolted to the adaptor yes so y can't it work backwards?? and also are the mounts in the same spot?? and will the start motor need to changed because of the adaptor pushing the flywheel out further??

[mischa]

so y can't it work backwards??

the auto crank is shorter then the manual (what ive been told the difference was), oposite for the auto so thats why it wouldent work backwards.

and also are the mounts in the same spot??

for the tranny? i think there the same but dont quote, anyway u got the manual mounts there anyway.

and will the start motor need to changed because of the adaptor pushing the flywheel out further??

have no idea, ill need to look into that too, will ask all this tomorrow.

[mischa]

i just realised is this i V6 or V8? cause i just saw my half brother inlaws VN V8s he just converted and that dosent need any adpter, just a stright swap.

[azzfox]

the auto crank is shorter then the manual (what ive been told the difference was)

hmmm never heard that before, even after all the manual conversion threads in the past (yes theres been LOTS of them )

can anyone confirm this?

There was even more before the crash! Thats what ive been told, but ive also been told alot of things that a stupid, people said the VN had 5 bolt flyheel etc... i know for sure there's a differents, but as for what thats what ive been told but im not sure about it.

[IhateRICE!]

well i finally have two car's and 2 gearboxes on the floor.

but is there anydifference in length on the series 1 cranks between the 2??

unsure of this because i have been trying to use a gregorys with missing pages so it's a big help.

anyway how is it going mischa??

[mischa]

i think all that changed was the number of bolts, still same length,... think. lol, ive gota wait tell my dad get back from his cruise (boat not car :P)to use his credit card! im not in a rush to get it done anyway. So you got both the auto and the manual outa the cars now? they a S1 and S2 there?

[azzfox]

I sent 'azk' a PM the other night and found out that S1 auto and manual cranks are different and S2 auto and manual cranks are the same. so you are going to need the adaptor not only for the different bolt pattern but also for the extra length.

[IhateRICE!]

well have ordered the adaptor just wait for "overnight" freight ( my Ar#e)

are well both series 1 cars
