I'm new to the forum, just picked up a 1993 Tracker, 1.6 8V, 5 spd with 170,000 miles.
I'm getting a vibration at 2800-3000rpm, in most gears, doesn't matter what spped I'm going. Is there a "common" problem(s) with a Sidekick/Tracker that this could be?
What type of oil pressure gauge can I hook up to the oil pressure sensor to get accurate reading?
Finally, what are good compression test reading for the 1.6 8V?
Thanks,
Scott
-
anywhere from 170psi to 190psi should be good...mine has 170psi on on 4 cylinders and it runs pretty strong with stock gears and 31s.
-
Were are you feeling this vibration? Is it from the motor, wheels, etc.?
-
If not a miss, I'd guess exhaust.
-
Thanks for the compression info.
Vibration feels like motor or tranny, because it's rpm not speed dependent I'm assuming wheel and driveshaft balance is a factor. Because it's a narrow rpm range and clears up by 3100 rpm I'm assuming it's not a miss.

You meant "is NOT a factor", right?

Probably not a miss, but keep it in the back of your mind. It's most likely a resonance with the exhaust. Get a good glove on and feel the exhaust vs. the frame nearby while someone revs it into range. Hopefully you'll be able to feel it. If not, that still doesn't prove much as the motor's not under any load. But if so, it might head you in the right direction.
-
Does it shake the same if you're just sitting in the driveway not in gear, or does it only do it while driving, in gear?
-
In netural there is no vibration, only in gear when driving. Feel it more in 3rd, 4th and 5th, when cruising under light load.
Because it happen at the same rpm and different speeds, I'm assuming they are not a factor, could be wrong.
In netural I don't feel any notable vibration in the exhaust. Shake it and I don't hear anything loose either.
Thanks ...
-
You could check the driver's side engine mount, and the main tranny/tcase mount. Maybe they have movement in them that causes the vibration.
The tracker isn't a green one is it? I owned one for a few years that i spent forever looking for the cause of a vibration, and could never find it. It would happen while driving at a certain speed though.
How bad is it? Does the car feel like it's out of control or anything?
-
No it's Blue :)
It's noticeable, but not a control issue like a front tires out of balance or loose tie rod. I'll check to mounts for play tomorrow.
-
what about a worn drive shaft yoke? Maybe get underneath and twist the drive shaft back and forth with hands and see if there is excessive slop. Maybe grease the fittings while your there too. Could do the same with the cv joints.
-
Waiting for a little better weather before crawling around and the next round of searching for the vibration.
On the oil pressure gauge question, what do I need to look for to make sure I get one that will read correctly with the 1.6 8V oil senor??
Thanks,
Scott
-
Looks like the tranny and transfer case mounts are shot, cracked and have tons of play. Checked Napa and CarQuest, they don't have listings for them. Where is a good source for replacement ones?
-
Hawk is a pretty good source of mounts. I had a miss going on the other day 2800-3100, but under no load and only 'till it warmed up. If you want to touch the exuast for vibrations a screw driver of other hand held metal object will work better than a glove. U joints generally will vibrate under acceleration and relax when coasting or decelerating. Worst case you could lift the rear and check with load by using the ebrake.
-
my tracker seems to vibrate too! not the whole car but the motor in general. the transfer case gear shifter vibrates a lot, my gf laughs all the time because it vibrates just like her uknow what. i dont know whats its from either. its not shifting back and forth all around all over the place, it just vibrates like it will numb your hand if you hold for too long uknow what i mean?
-
worn out engine mount perhaps?
-
Sounds similar, feels like motor/tranny, not the whole rig like tires out of balance.
Just ordered the tranny and transfer case mounts from Hawk, should have them in a few day, we'll see if it takes care of it.
Motor mounts have some play but seem OK. Last motor mount I broke was in a Mustang, the motor torqued up and cut the upper radiator hose in half >:(

well the tracker doesn't quite have THAT level of torque either :)
-
This is probably irrelevant, but ill just share....
I had a bad vibration, i first thought it might be the mounts but as I went under my tracker, I noticed that the U joint was out of the place, and fixed it. No more vibration.
-
Just a little food for thought for you, look down at the front of the engine while it is running in neutral and look at the pulley on the crankshaft. Does it look like it might be wobbling? You might have the infamous bad crank key-way. That can cause so many problems to look like they are to blame when in reality that is all that is wrong.
-
Thanks for the additional ideas
u-joints look good, no visible problem in them. Received the tranny and t-case mounts from Hawk, although between a few days of snow and now rain, haven't had a chance to install them.
I'll check the crank pulley today, that sounds consistent with an engine rpm verses mph vibration.
-
Sometimes the u joints look good but are siezing up. That would cause a vibration also. I would recommend actually removing the drive shaft and moving the joint around by hand to see if it is free!
-
Put the tranny mount in, no change.
Went ahead and replaced the rear u-joint, no change
Re-phased the driveshaft, now vibration is only at around 3000 rpm and 55 mph.
I did notice the slip yoke has .015-.025 of movement, measured at the u-joint ear. If I slide it all the way in, about an additional 1" from it's normal position, there is no movement. Is this normal? I can't find a spec for this in the service manual.
-
I dont know if this could be a factor for you or not but I bought a 66 F100 years ago and the previous owner had replaced the engine. He put an engine out of an automatic in it and did not put the flywheel from the standard back in and it vibrated like hell at higher RPMs. I changed the flywheel back to a standard and it was like new again. Just a point tgo ponder.

Hmmm, can't hurt to check the engine and tranny numbers against the VIN.
-
Correct me if i am wrong. But aren't a manual and auto flywheel totally different? Auto has no face on it?
-
yeah i believe your right.
-
After having a few shops check it out, the current theory is a worn pilot bushing and/or clutch hub. Looks like new clutch time.
Does anyone know what the tranny/t-case combo weighs and where the balance point is for it? Can't find a tranny jack for rent so I'll have to weld up a plate of some sort for my floor jack.
-
Tranny 101!! there's no flywheel in a automatic, it's a torque converter...just to let you know!!
-
So what does the torque convertor bolt to then? Smartass!
-
Ring gear!!
-
I don't think you have the correct terminoligy. The torque convertor bolts to the flywheel. Or some call it a flexplate. Wrong part dude!
-
BTW if you're able to bolt a torque converter on to a standard trans flywheel, i want to see it!!

Ok now show me where in this past conversation I once said that a torque convertor will bolt to a standard flywheel. I made a point that they are different. Then you stepped in and told me autos don't have a flywheel they have a torque convertor. You are right about the convertor part. But what does that covertor bolt to. A flywheel! An auto flywheel, not standard. Get your facts straight dude!

sick burn... i think he's thinkin of a clutch maybe??? ??? ??

I was talking about this, not about you
-
:o :P that got deep quick
-
And i'm done, i'm not here to pick a fight!!!
-
no one is ...... just a bit of fun.... all egos aside happy wheelin guys.
-
You too, man!!
-
night guys its gettin late here. 12am... gottta be up early.. taker easy and geter dun.
-
I am not here to pick a fight either! Just defending myself. You came accross cocky with the whole tranny 101 thing. When you want to prove someone wrong have your facts straight. I am just hear to learn and share knowledge and experiences.
-
Well, if you think i was cocky with that, i'm sorry!! ...and next time ask, before calling people smartass
-
:o I'll try to keep my questions from stirring things up in the future ... ;D
So, does anyone know how many pounds the tranny/t-case combo is and where the balance point for it is?
-
Ok its my turn to appoligize for my error. It was 30 yrs ago and a lot of alluminum cans. The truck I bought had a 6 cyl 4spd and the guy had put in a 289 and used the flywheel from the 6 banger.
I originally thought it was possibly the harmonic ballancer but after talking with a backyard mechanic he suggested a flywheel from a 289. I pulled the tranny & clutch, buzzed off the flywheel changed it out, I dont remember if I changed the clutch and pressure plate but when I put er all back together she ran real good. Sorry for the brainfart.
Just so you all know I think this is a great info sharing site and it has helped me to understand these little Zukes
Keep up the good work guys

so back to the trak vibration. it could be weak motor mounts. just a thought.
-
Maybe just leaver B and get ahold of the Florida boy and sell er to him and then he can have another women love my zuki LOL
