MARSDALEBEAR Posted April 22, 2004 Posted April 22, 2004 Just got myself some vernier duplex timing gear for my X Flow,but guess what...dont know how to set it up Can anyone run me through it before I fit it? Quote
bofus Posted April 22, 2004 Posted April 22, 2004 read the info in either the kent cams catalogue (used to be in the there! or the intro in the burtons catalogue Basically you get TDC on no1 using a dial gauge, attach the protractor to the crank so that the protractor can't move. Now move the crank to the cam timing position, and lock the crank. Move the dial gauge to no1 inlet rocker ( i think normally it is no1 inlet!!!, you now have to obtain max valve lift whilst keeping the crank still. you do this by using the adjustment in the vernier kit. tighten everthing up, turn the engine over a couple of times and recheck. so you need to know the cam timing have a crank protractor and some bits of stiff wire to make a pointer have a dial gauge and mag base or some other bracket patience:) Quote
MARSDALEBEAR Posted April 22, 2004 Author Posted April 22, 2004 so you need to know the cam timing Thanks Bofus,seems pretty straight forward. Anyone know the timing for a BCF2? Quote
worzel Posted April 22, 2004 Posted April 22, 2004 According to the Kent Cams Catalogue......... Inlet timing at full lift = 108 deg Steve Quote

When you get TDC, attach protractor to crank with a pointer at 0 degrees, move dial gauge to lifter/valve cap, then rotate crank to get max lift at valve, record max lift value, rotate crank to degrees specified by manufacturer, then adjust vernier to get max lift value again. I don't think you can get to max lift from TDC with the crank locked in position - can you? I think there's another method which involves adjusting the camshaft to zero lift (ie totally off the lobes) on both inlet and exhaust at TDC on the compression stroke. Which you can then check by finding the degree at which max lift is achieved for comparison with your cam spec. I think thid method is that same as bofus's if you change 'max valve lift' to 'min valve lift (ie zero)' in his explanation. There's another method to do with finding the 'inlet centreline' or something - a quick search for degree camshaft on Google should find a few guides. Please note I've not done this myself but will be in a couple of weeks - it's just what I've read. Mike Quote
bofus Posted April 25, 2004 Posted April 25, 2004 I think I see what you are saying, but the last couple of times I have done this (x-flow & CVH) It has been easier the set the crank and lock it (using the ring gear) and then use the spanner on the cam sprocket/pulley bolt whilst the vernier bolts are loose, I guess you can set the cam and then move the crank whilst the vernier is loose. I think your way would be more suited to x-flows being setup with off-set dowels for the cam pulley. Gav Quote
Mike H Posted April 26, 2004 Posted April 26, 2004 Fingers crossed my timing gear and heads should be arriving this week, so I'm sure it will all make sense to me soon! Mike Quote
MARSDALEBEAR Posted April 26, 2004 Author Posted April 26, 2004 Please note I've not done this myself but will be in a couple of weeks - it's just what I've read. Mike I think that I might just wait untill you have done yours! Quote
worzel Posted April 26, 2004 Posted April 26, 2004 See this.... Burton Camshaft Timing Cheers, Steve Quote
TonyFerrino Posted April 27, 2004 Posted April 27, 2004 What are the ways of locking the crank in position so it doesn't move while you adjust the Verniers? Can you not just put the car in gear or do you need a tool? Quote
Mike H Posted April 27, 2004 Posted April 27, 2004 I think your way would be more suited to x-flows being setup with off-set dowels for the cam pulley. Gav bofus/Gav Just read your bit again - are you saying you have FULL adjustment available via the vernier in your cars - ie. 360 degrees? Is that how they all work, do you know? thanks Mike Quote
