Advice/help stripped head on bolt
|
|
|
I was attempting to replace camsahft sensor, which I had to replace about 4 months ago and has failed. Very tight space with about 2" to move ratchet and can't get hand in space, only 2 fingers. First bolt broke free no problem, second felt like it broke free however feels and slightly looks to be stripped. It's a 5.5mm. and very hard to get socket properly or perfect I should say fitted on the bolt head. Very tideous. How would you pros attempt to remove this bolt. Can't get vice grips or anything I have in tight spot. Recommendations please.
Randy

You might have to take the synconizer out so you can get at the stripped bolt head without all the garbage in the way. If you take the syncro out, you'll need the special tool to line it back up with #1 at TDC compression stroke.
Most of the time a six point 1/4 5.5mm swivel socket taped on the end of an extension works good on those.

Hey Discrete, thanks, I was trying an extension with a sxivel (not taped) and just couldn't get to this thing right. But I have a 'ole boy mech on wheels' who says he has an old trick he used on older moldel with distrbutor that rquired a 5.5mm but usung a trick with a special fitting mounted to the socket somehow. I liked the idea of removong the synchro but this guy says he wants to stay away from the synchro. Anyway, will follow up with remedy. It was late last night and this is just a drop in the bucket of problems going on, so sorry to come off rude if I did. Thanks, Randy
Randy

It's alright Randy. I been in those scenarios a few times and the best thing to do is walk away and take a break. Usually when you come back, the stuff comes right off or goes right back in.
What happened to the old sensor? Sometimes the syncro's shaft bushing wears out and causes the interrupter to rub and tear up the sensor. Make sure that the shaft isn't walking around when you get the sensor off.

If you're gonna leave the synchro in, maybe bump the engine over to get the bolt in the best position as possible.
Actually it would be easier to just remove it and do in on the bench, but as mentioned, you would need either a special tool or a scope to set it up....
If you do pull it and don't have either, make sure you mark the position of the sensor and mark the base of the synchro at the block. The one other advantage you would have to pulling it as opposed to leaving it in the engine, there is a little welsh plug on the housing. If you take that out, it is a thread hole you can put a zerk fitting in & lube the shaft bushings as they are prone to squeeking & seizing up.......

Got the sensor off by removing the coil pack mounting and throtle body mounting brackets giving a perfect birds eye view with plenty of room to the sensor. Did not remove syncro. Ended up having to break the sensor casing...vry..vry carefully to remove the stripped bolt. Old sensor, actually only afew months old, had some metal shavings and lots of gunk in the cap and on the magnet causing the malfunction. Shaft looked fine but I didn't clean it enough last time in the dark. Took some compressed air and blew it out and lots of sh@*t came out. Got it cleaned good, replaced sensor hooked up handheld. Car runs great with only dpfe code which I knew about. When I took out the original sensor a few months ago, the top of casing was melting and inside magnet had broken, but again, no visible damage to shaft. So maybe some slippage as you mentioned. Just cross my fingers and hope not.
So on 1998 Explorer 5.0 it's fairly easy to just remove the coil pack mount to give plenty of access to the sensor. Just 4 bolts and a few elec connectors. Thanks for the help, Randy

If the syncro shaft is wobbling around in there from a worn bushing it won't tear up the interupter because it is metal. It will tear up the sensor and act like a cheese grader. Hopefully your new sensor doesn't end up like that later on.
