Me again

[CMF_Glenj]

Ok tried to look for the opening/closing, but me thinks im rather way out here or there is way to much slack in the chain

when moving the crank quite a bit the cams dont really move so i can't gauge when the lobe touches via notches/clearance drops to zero, when the cams do finally move the pulley notches are no where near.

Any thoughts
Cheers

you have to always turn the crank clockwise glen, and have you fitted the tensioner and released the ratchet inside, to lock it ?

 

[CMF_Glenj]

yeah always have been bud, yeah tensioner on and released the ratchet

referring to what you mentioned above about the crank could move about 4 notches before cams would move, could it just be this or sound like way to much slack

 

[CMF_frank2]

4 notches is pretty normal mate, and fit a thin feeler gauge under the exh cam and slowly turn the engine from about 40 deg before tdc, and you will feel it release the feeler at about tdc, then slip the feeler under the inlet cam and it should bite/trap the feeler at about 30 deg after tdc ?

 

[CMF_Glenj]

ok will look at this, would the exh lobes not be pointing around 12oClock here tho?

when at TDC the lobes are at 9 & 3ish just seems i move the crank quite a bit before the exh lobe ramp starts to meet the bucket

 

[CMF_frank2]

your lobes should be here @ tdc mate

 

[CMF_Glenj]

now im lost when at TDC cam sprockets are at 9 and 12 how them lobes pointing there or is this on next stroke?

 

[CMF_frank2]

its the other tdc innit mate

 

[CMF_Glenj]

want it in this position ^ ? this is the position i thought you meant? if not around 20 deg getting confused with the TDC here sorry bud

 

[CMF_frank2]

nah this one mate, fit the feeler under the exh cam and slowly turn the crank from about 40 deg btdc, and it will release about tdc (make a note of when it releases).
then do the inlet cam

 

[CMF_Glenj]

cheers bud will try again tomorrow, can i put the 3 thou feeler on shim/bucket and completely turn the lobe on to it as rotate to this position this ok?

 

[CMF_frank2]

yes mate, use a thin feeler or else spin the bucket

 

[CMF_Glenj]

cheers buddy

 

[CMF_Glenj]

ok tried this earlier,

Inlet gripped the 0.015 feeler around 20deg before TDC mark (your saying it should be after?)
Exh did not let go of ^ feeler until way after the TDC mark maybe 30/40 deg

 

[CMF_frank2]

if thats 15 thou glen (inches) ? then its too big a feeler mate

 

[CMF_Glenj]

smallest iv got bud.. i had to go and buy the lower set

0.015=15thou? do they do an even small feeler guage set?

 

[CMF_frank2]

hmm, .015mm is mega thin mate ! is it metric or imperial ?

 

[CMF_Glenj]

yeah it is bud...not to sure to be honest bought it from local car shop

 

[CMF_frank2]

ahh, sounds ok then mate
so it looks like the cams are running only a bit retarded eh.
if you advanced them 10 deg, the inlet would bite @ 30, and the exh would bite @ 25ish eh

 

[CMF_Glenj]

what do you suggest bud, im thinking stick it back together see how it goes would i able to do changes after or would it fook it up?

off topic i know (or shall i make a new topic) have you got any pics of the injector seals, machine shop took inlet off so i dont know what came off it, the doughnut ones are still there
Cheers

 

[CMF_frank2]

yes see how it runs eh glen, doing the 12 o,clock to 6 o,clock/half a tooth advance is easy to do (just turn the engine 360, and reset the cams as normal) but to advance 3 o,clock or 9 o,clock would mean removing the timing cover and sump, to reset the lower chain.
and this thread is already big/slow loading eh

 

[CMF_Glenj]

lol yeah cheers buddy
