Timing and crank sprocket questions

[shokid24]

Ok so I'm doing a front 60k on my 94 mtx. I had installed the crank sensor and gapped it. I put the crank gear on and it seems the lip of it will hit my CPS. Do I need to raise the CPS to avoid it getting hit by the gear? Or do in gap the CPS with the gear on?

Timing. I'm not quite understanding what sho Phoenix is saying. I lined up the crank gear to the dots and line but I've cranked it forever and it seems the cam gears won't line up. Do I just keep turning or can I turn the cam to line it up? Getting this timing right is beginning to really suck

it is impossible to gap the cps unless the sprocket is on. the shutter wheel lip is what you use to set the gap.

you turn the cams until the dot on the cam sprockets line up with the line on the metal part of the cover. you turn the crank until the dot on the crank sprocket lines up approximately with the line on the oil pump. then you slip on the belt, making absolutely certain that the lines on the belt are matching the dots on the 3 sprockets. (I find it much easier to do this if I start with the crank about 1 tooth counterclockwise from where the mark on the pump is.

what is absolutely vital is that the lines on the belt and the dots on the sprockets line up once the belt is on, and after the belt is tightened those dots are lined up with the marks on the cover and oil pump.

I'm an idiot! Staying up too late trying to finish. I had the cps in backwards, which explains why the lip of the gear was hitting the cps.

Weird spuder from exhaust after 60k

I'm pretty sure I had set the timing right. Plug wires seem to be right if shophonix is correct. It idles right at 1000 rpm. I dunno. Should I re do the timing. Or how do I check it.

 

[rubydist]

check the timing by lining up the dot on the crankshaft sprocket with the line on the oil pump. at the same time, the dots on the cam sprockets must line up with the lines on the metal timing cover. if all 3 line up, timing is correct. if any do not line up, the timing is off. it is vital that they line up, even 1 tooth off is not acceptable.

Be sure the wires are correct, as that sounds like a cause of sputtering in the exhaust to me.

Got cha I believe that is where I went wrong. Mis red the guide

How bout this.

Upon setting timing I think the belt is funny. I lined up all marks on all gears and started with cam pullys. Lined them up and proceeded to the crank gear and it wants to rest at the lower 3.2 belt line.

Start with the crank gear and line up to the higher 3.0 line/. And cam lines are one space to the right.

My belt is readable from drivers side. And still need to switch 5&6 plugs around.

I think/ sure I bent my crankshaft gear washer. I hear a nasty scraping sound from that area. What to do about that and where to find a new one?

When tightening down the W/P belt tensioner a long bottom bolt from the bottom right snapped with an inch to go. Gotta find a way to extract the bolt head and find new bolt to hold the tensioners on. Maybe a new setup. Also the A/c belt tensioners bolts n setup. One didn't seem to wanna go in n thread . Probably wrong bolt.


Some how upon a test drive the cv boot blew. Looked like the SHO literally took a Shi*

Thank for all your help with this easy looking endeavor.

you mean the shutter wheel on the crank sprocket is bent? you can straighten that, but you might need to remove the sprocket to do so. you might be able to bend it with a screwdriver while its still on, just be careful against what you pry.

look in my parts for sale thread - I have the accessory stuff you need if I understand it correctly.

 

[shokid24]

Thanks again. Yeah I'll look at your sale stuff when I'm out of work. I think I may need the alt tensioner cuz I had to grind a bit off to get a bolt in.

Doing something for the first time is always difficult.

When it comes to bolts, I now take a piece of cardboard and draw a picture of the part that is coming off and I push the bolts into the cardboard at the appropriate location. Frequently, there are different length bolts associated with a part, and it saves a lot of time if they get replaced exactly where they came out.

The crank being out one tooth on the timing belt is really common and there are a lot of SHOs out there that are being driven with this condition. At least you spotted yours.

Good luck with the repair and don't get down on yourself... happens to everybody.

This is what I mean by the belt is weird. The crank is lined up to the 3.0 mark but the cam marks on the belt do not line up.

What are you pointing the dimple on the crank sprocket at?

The crank gear dimple is pointing at the oil plan mark on the bottom right.

Ok updates. Switched 5&6 on cool pack , seems fine now. Still need to straighten the shutter wheel on crank sensor. Replace half shaft cuz of blown boot. Replace belt tensioners. Replace the trans output shaft seals. And find and replace the seal where the rod shifter enters the trans. I see leakage.
And my thundervolt 8.2s are on my doorstep. Big yay
