URGENT! Catcams pulleys and cambelt cover

[robi1000]

Hi guys!

I have a problem, again. I bought Catcams pulleys for my willy and now engine cannot turn because bolts on a pulley hit the cambelt cover. How do you guys solve this?!? Aaaaa, my car was broken for over a year and now it runs (if I take the cambelt cover off) but I can't put it in a car without cambelt cover.

Here are some pics:

Have a search this has come up before, i think one of the answers was to get bolts with shallower heads

[richy]

the kit i got came with another set of bolts which you have to swap to because of what you have described mate

did yours only come with them bolts?

With how much these cam's cost you would think that the bolts would fit! :roll:

[robi1000]

Nope. My pulleys were supplied without these extra bolts. :( Now what? :x

doh, not sure... i got my pulleys through stan on here, might be worth dropping him a pm etc

[robi1000]

I can't find that topic in which this was discussed before. Does anyone have a link to it? Or title of that topic?

chop shop :wink:


cut the offending bits out in a symetrical /tidy manner on the cover,
space out as deisred and secure clear perspex sheet
using rivets or similar .
well you get the idea 8)

[robi1000]

Ha ha! One of my friends suggested the same idea, but isn't this a bit... Hmm, how would I say this... Pimp my ride style? All I should do then is just add a few blue LEDs and voila! :D

I can remember it, but had a search and couldn't find it

[2 live]

use dome headed bolts mate..this eradicates the problem.

[robi1000]

Where can I get these?

[richy]

do you have any stores you can buy bolts etc from??? like a b&q of sorts

[robi1000]

Yeah I think we have few around. Any special precautions with these bolts? Strength, thread, etc.?

[richy]

tbh i cant remember what mine looked like as was over year ago! but id say they would need a wider head ie built in washer type to make sure it holds nicely and hi-tensile if pos, not sure whats available in that size tbh

thread will need to be same of course too

[robi1000]

Tnx for your answers guys! I'll see what I can do.

[cliokongen]

You are not the only one having experienced this problem.

I did - and tbh i find it very upsetting that the product does not work straight out of the box.
The bolts that come with the verniers seem to be very bad quality too.

Change them for something in the 10.9 quality range.
I found it very difficult finding suitable bolts that clear the cover.
I took the risk i found some bolts i had lying about.
Fingers crossed they will hold.

One more thing.
Make sure the verniers clear on the back - towards the head area.
See pics.

Thank you Michael! You've been very helpful! I'm also a bit disappointed that pulleys don't fit straight out of the box, especially if you take the price of this pulleys into account. I've solved so many problems so far and I have to say I'm a bit angry because these bolts are causing more delay! :evil:

[cliokongen]

Know that feeling all to well..... :-)

Michael

[matty w]

dont think its just cat cam pulleys i'm sure my pipers where the same

[cliokongen]

I can think of at least one more make of pulleys which does not fit.

Scary!

i posted a thread on this...

standard bolts with washers. item supplied without. ones i bought with washers and low profile head..

i think there M6 x 1.0 @ 12mm long with the washered cap head..12.9 i used and torqued up to 15 nm

[robi1000]

:goodposting:

[robi1000]

So you used the ones on the right? Not the middle ones?

[Lunner]

Yeah, ones on right, as they have the shallowest head

[robi1000]

Here are two vids of my car running!

[Lunner]

Always best feeling in the world isn't it :)

[robi1000]

Oh yeah... :D :D :D

[Lunner]

What cams do you have? 225's?

[robi1000]

Yup.

[cliokongen]

Great! :D

Whats the rpm @ idle?

Michael

[Lunner]

Think you can have normal with them

[richy]

yeah mine has 225's and idles pretty much as normal rpm wise, although it dont idle perfectly flat etc like a normal f7 would.

[Lunner]

think i'm going for 208's boys, wee bit wilder

[cliokongen]

Just being curious! :)

I asking because my F7R with 225's idles at approx 1400 rpm.
We had to map it like that.
It was simply to rough at 950 +/-50 rpm.
No air leaks or anything.

I believe i timed them correctly (to specs using lift@tdc method) but i could be very wrong.
Maybe i did not get it right and timed the cams with too much overlap?

this is a short vid of how mine idles, this is pre remapping too
running 225's etc aswell and sits at 950rpm ish

[cliokongen]

Nice and lumpy... :-)

Think mine was just about as lumpy @ 950....
That was before 2,5" bore exhaust, larger injectors and remap.
My lightened flywheel might have something to say also?

Michael

[stan]

Changing the bolts and removing a small ammount of material on some head castings is a small price to pay for using a part which has such in-built quality IMO

Michael is yours a lightened std flywheel, of an aftermarket billet item?

You shouldnt have to have it at 1400rpm...
Has it been remapped? What cc are the new injectors?

[2 live]

hmmm. this is mine with 260 kents in.


http://uk.youtube.com/watch?v=x_49fGKZvpg&feature=channel_page



and with 270s

[stan]

what lift at TDC did you set them to?

and was it remapped?

[stan]

Also the last vid is with it on ITB's?

If you had got that un mapped, the idle would have purred at 950rpm...ITB's make for a luuurvly idle :D

[robi1000]

Hey guys!

I bought these bolts today. I cannot find 12.9 ones with built in washer and torx head. :?

So I've bought these ones. These are 16mm long, 10.9 and imbus head but heads are not as wide as I'd want them to be. Do you think these would be ok? I guess I'd have to cut them to 12mm?

I agree totally - It is a small price to pay - but would be great if bolts was of the same high standard as the pullies.
Removing a small amount of material from the head is expected - theres always some casting imperfections etc.

Flywheel is a lightened std. item. A rough guess is no more than 500g has been removed.

It has been remapped. 198bhp - 230Nm
Performance is ok i guess.

Injectors are 300ml
Mixture and lambda is perfect through the rev range.

Craig - ITB's are on the shopping list.... :P
