Why would you put all the lobes facing down? Get your number one piston to top dead and make sure you crank is lined up tdc.

I think if you put a pry bar behind the knuckle and give it a quick bump it will just pop out it has a ring on the inside that holds it in. Just uses pressure to keep it in place I will look in a few but I am sure that is what to do.

SOURCE: How to adjust the timing on 4cyl '95 dodge dakota

unfortunately you do have to tear it all down, but it's not as bad as it sounds. the 4cyl is easy to work on. you don't have to put it all back together to find out if timing is correct. if you have a good fully charged battery just run the engine with only the timing belt attached. (of course be absolutley sure to keep tools, engine pars, and hands clear!)

put on the parking break and the trans in neutral

tear down to the timing belt

adjust to tdc (there is a hash mark on the cam gear)

remove or losen the idler pully

allign the timing gear and crank gear. there are marks on these from the factory install.

tighten idler pulley

run engine. it should be fairly obvious if it's too advanced or lagged when you give it some gas.

The crankshaft should have the timing mark on the crank pulley (Notch in the outer edge of the pulley near the keyway) It should align with the timing mark on the oil pump. (With the keway turned to about the 3 O'clock position.)

Align the marks on the camshaft timing pulleys with the corresponding dots on the front plate.

If you are installing a new belt, it should have 2 solid white lines printed on it that you would align with the timing marks on the cams and a dotted white line to align with the timing mark on the crank.

It makes a difference which way you put the belt on. (Which edge faces the front of the engine.) Most, but not all brands of belts have arrows and the word "FRONT" on them to tell you which edge of the belt shoud face the front of the motor. If there is no mark to tell you which edge is front, the letters on the belt must be able to be read correctly as viewed from the front of the vehicle.

02 Chrysler van 3.8 came in with blown head gasket and a check engine light for misfire no1 cyl. Installed new head gasket new rebuilt heads plugs wires started up still misfire 1 and now 4

erratic compression indicates a cam lobe problem or cam follower problem
with that many miles on it , the cam shaft will have wear on it but the rest of the motor will have considerable wear including possible ring problems on the numbered pistons
If the body is rust free consider a new -out of the box engine as a cheap plug to stop the repair waste of money

Hi trying to set the timing on my j1 elantra its a 16 valve and each cam has two marks on it.so my question is what positions should the cam lobes be at when timing is supposed to be correct.thanks

no 1 piston tdc
the cam lobes for no 1 piston should in such a position so that a slight turn of the cam shaft one way makes the exhaust start to close and the inlet start to open or the other way the inlet start to close and the exhaust start to open
this is known as valve rock or valve overlap and occurs when the cam shaft is properly timed to the tdc position of the piston
for a twin cam engine the cam lobes position will be the same operation just that the inlet cam rock will be for the inlet cam and the exhaust cam rock will be for the exhaust cam

I have a 2000 polaris sportsman335 and the camshaft lobe is flat seems the part has been discontinued any ideas on how to fix or where to get the part thanks

the camshaft lobe is part of the cam shaft so if it is worn down then you need a new cam shaft
I would check with the service agent as I seriously doubt that cam shafts would be discontinued items
the same cam probably fits a range of engines

How to disquinguish the intake cam from the exhaust cam,,mine got mixed up while doing a headgasket job .

the cam shaft may be identifiable but I doubt it as the lobes will be all the same .It may take a trial fitting of the cam shaft to determine which is which. Place the no 1 piston on TDC and install the cam in the exhaust side of the head. position a the no 1 piston cam lobe in the just closing position. Check where the timing mark will be in this position ( the engine make and sized would have been an enormous help here as the key position or timing mark on the gear would have revealed what cam it was). Place the other cam in the position where the no1 cam lobe is just opening.. This is called valve overlap and from the positioning of the timing marks will show if the cams should be interchanged . The marks will either both face down, face each other or face upwards. If they face out wards away from each other then interchange the the cams and if that makes the marks face each other then it may be right. Another way ( probably simpler will be to put a cam in place and the cam lobes will be directly in line with the rockers over the valves or directly over the valves. Workshop manuals are a big help when doing this work.

How do i put the steering wheel back on my 1989 buick lesabre ?

If you look very closely you will see either a small demarcation or scatch on the center ring and steering shaft. Line these up and replace the washer and nut. Then torque to company specs. 25-35 ft lbs should surfice.

Have a Hyundai Tuson. Worn out cam shaft gear after 107000klms. Rockers worn, cross heads worn. Cam shaft marked a lobe. Can these cams be ground or will you have lifter problems.

if all these parts have wear marks then all the components will have to be replaced with new.you can have the cam reground but its probably cheaper and quicker to replace with new by the time you find a place to weld regrind the lobes and get the part back and hope it won`t give you a problem,so you don`t have to tear down again.

I need to correctly put a F250 with a 86 351 winsdor motor back in time? - time chain and gears

Not terribly complicated. Set the crankshaft at TDC on timing scale before you start, as a reference. If the cover is off just stick it back on there for a minute and same for harmonic balancer.
Once you have done that you should see a mark on the lower gear, either straight up at the top or straight down (if at bottom, put damper back on and turn till it points up.) You should be able to find a corresponding mark on the cam gear. That mark needs to point down, directly at the one on the crank gear. To do that, loosely install the cam gear on the cam and turn it till it lines up. Remove the cam gear and place the chain over it and the bottom gear. do not change the crank or cam position. To check for proper alignment, put the balancer on the crank ant turn it exactly two turns. the marks should return to original indexing. Make sure you have everything tightened up and then put the remainder of the engine back together.
