hi guys - doing the front exhaust studs and 12 years of corrosion meant sheared studs.
Problem is the pipe wont budge!
All is done to facilitate this, however, I've used a drift through the frame and club hammer to try and tap it off (the left side as you look from the front) and nothing is budging. It's all been soaked in penetrating oil etc. for a few days and hit with a hammer from underneath to try and and loosen the corrosion in the stud thread.
Is it just do a bit more than a healthy tap or is there anything else? I'm presuming heat is only useful for the stud extraction due to the engine block and stud being different metals?
Although I’ve never attempted exhaust stud removal on the storm, I’d bet my left arm that they’ll snap when you try and remove them. One thing I do know is that I wouldn’t even try and remove the ‘remains’ but just drill and tap a new hole. Dr Honda with his combination of cheap mild steel bolts and alloy weld themselves together like no other.
I gather that you are trying (and struggling) to remove the down pipe from the head, is that the case? Once again I’ve never had the pleasure with the storm, but surely the simples method is to use the exhaust in your favour and ‘gently’ use ‘it’ to facilitate some leverage, in other words wiggle it a bit while holding it at the back. But there again, like so many other storm jobs a big stick and a very large hammer will no doubt be required. This of course is perhaps a load of bull and therefore just ignore me.
yep, all cans, rear header pipe clamp released and loose, downpipes move up and down. Just effin' frustrated at the moment as it looks like i'll be cycling to work tomorrow
if the downpipes move up and down they should pull off unless you've left the bolt in under the footpegs...that happened to me when i had to take the front head off to repair after front cct failure...as for snapped studs...i had it drilled out and retapped then fitted bolts with a locknuts on them incase it had to come off again in the future,i can just hold the bolt head and undo the nut and if the bolts siezed i can cut the head off the bolt and use as studs again...if that makes sense.
Looks to me like you have sheared the studs when you removed the nuts? Where the studs should be stuck out, they look flush with the collar on the exhaust.
I would get a bit hammer and a small screw driver and just loosen around the edge of those studs where they join that collar. On mine there is a little big of clearance and studs arent tight inside that hole. If you hammer away at it, you will loosen it up.
As for then removing the studs, you said you have already seen a thread I made about it.
Try to flatten on side of it first with a file, get mole grips or a pair of stiltsons on there tight and turn gently while hitting the stud with a hammer to shock it free. As you will have seen one of mine came out easy like this. The other had to be cut out.
yep just now, plenty of soaking and whacking and popped off - must have been well corroded. Looking at the pipe and the cylinder block there is very little evidence of a gasket existing!?
Look very carefully in the cylinder head where the front pipe goes into as the exhaust gasket gets well flattened, sooty and camouflaged to blend into the cylinder head. Try carefully scraping/dislodging it out, as if you don't and put a new gasket over the old one the exhaust won't clamp and align correctly.
It may be that your whole purpose in life is simply to serve as a warning to others.
been wiggling and tapping and getting to near a whacking now!
