What am I doing wrong? Had to take the rocker assembly off 1 and 4 to fit a new exhaust/J-tubes and when putting back together to torque them back (10ft/lb) I thought I'd adjust/check the valve clearances.. Number 1 doesnt seem to rattle at all and Ive now screwed the screws out all the way to see if I can get a feeler guage in. Not happening - I assumed I was in TDC (no timing scale) as the valve possitions looked closed on cylinder 1.
What you're doing wrong is guessing. If it everything went back in the same place it should be fine... or would have been before you lost the adjustments. Get a timing scale! Why the heck were you taking rockers off to fit j tubes?
Prob need to give more details for help.. type 1/ type 4 engine But can't really guess TDC.. no marks on pulley at all? Sent from my SM-G930F using Tapatalk
Good question about removing rocker .. need to get a pushrod tube out to fit adapter stacks... Guessing I need to fit a scale.. I’ll get one ordered. Sent from my iPhone using Tapatalk Pro
Yes you must have a scale, TDC the mark is not at the top like type-1 engines. Why J tubes? Racing bus?
The other thing with type-4 pushrods is when you chuck them down the tube they sometimrs want to sit on the edge of the follower and need encouraging into the centre. Could be that?
For sure that's not at TDC, but if you removed from both sides of the engine they can't both be on the firing stroke. You've also lost the wire clips that keep the pushrod tubes in place.
these semi-ball bearings have a flat side and a ball side.. at the risk of the usual suspects taking an interest.. I assume it’s balls-out touching the valve.. or should it be flat surface to flat surface? Sent from my iPhone using Tapatalk Pro
id suggest checking that the push rod is sitting correctly in the tappet/ cam follower. easily done for it to drop out and sit on the edge while you bolt the rockers down.
I think it was because I had the ball side out.. with the flat side out I have plenty of adjustment Sent from my iPhone using Tapatalk Pro
Buy a scale and the pushrod tube retaining wires. How have you adjusted the ignition timing without a scale? Be careful not to overtighten the pulley bolt turning the engine, it’s better to use the alternator nut.
Thanks all for your help - all back together and running OK, if not as quietly as I thought it might! Missing parts are on order
