It started with an alternator upgrade......

The alignment pins on the sides are sticky sometimes. a few oil pan bolts may need to be loosened as well.

 

Timing cover just needed some wiggling and a big pull... It's off!!

The timing chain has a fair amt of slack so I am replacing while I am in there.

A thin round spring was on the end shaft off of the crank when I removed the timing cover. Something yo do with the main seal?

Also the flat disk on that shaft by the timing gear .... Does the curved edge go toward the engine side??

Another website mentioned caution about burning out the main seal. Any special prep or lubrication I needed to do when I put the timing cover on? I know that the oil pump gears needs to be packed with Vasoline ... Any other considerations?

Thnx gents!!!

 

Ditch the fram filter and get a wix.

 

x 1 billion on that...
fram spends all their money on marketing... not on filter media...

let us know how the flowkooler works.. I have heard mixed reviews...

I always coat seal lips with oil before installation.. just to make them a bit more pliable..

Billy, I think the thin round spring and the flat disk with the curved end... these mount to the nut on the end of the cam. There should be a large washer with a notch in it that one end of the spring fits in, the disk clips on the end of that spring on the nut, and the flat side should ride against the timing cover (there should be a round circular wear mark off the end of the cam from it). I put some assembly lube on mine when I assembled it. I don't think I have any picts of mine. I think the Blueprint article Tarry99 put together showed it or mentioned it.

 

I lied: I think it looks like this?

 

Hum, last time i took off the timing cover, never see that spring....what is the utility for that?

 

Spring is supposed to reduce cam walk to and fro but there are mixed feelings about the necessity of this. When I replaced the timing set on my tux (about 50k) there was no spring or button or even any wear marks to indicate that it ever had one on it.

 

First time i see that, even my previous 304 wasn't having it. So been running those engine for 6 year, don't think i cause any trouble.

 

The spring I am taking about is near the seal on the crank shaft....

Any thought on the other questions????

 

Only other spring i had was the timing chain tensioner, but it was not near the crank, do you have a photo?

Same for the flat disk, I am at a loss. only disk i had was a thick washer with a notch in it that was on the end of the cam: timing gear, fuel pump essentric, distributor gear, washer, bolt, the spring i showed in photo above.

Your timing gears / chain get removed together from the cam and the crank. A little on each to move it at the same time to and bottom. I replaced mine, so my removal method was less about finess, may be someone could mention their method here.

 

Progress!!

Timing gears / chain replaced. It required a puller to get off the old gears. (Thanks to my awesome neighbor Dan who came over with his puller)

To get on the new Milodon double roller set it required a few taps with a large socket / hammer over the cam gear to get it fitted.

The garage is a bit hot at 95 degrees but I hope to get in there early to get the timing cover on.......

 

That is a good looking jeep love the color.

 

Ok... Getting ready to install the timing chain cover. Having an issue with the gears on the oil pump. They spin nicely before I put the oil filter adapter on. Once it is on with the gasket and torqued to spec I cannot turn the shaft at all. How would I increase clearance? Extra gasket??

This is a timing cover set that I bought from Bulltear. I am thinking of contacting them on this one....

 

they have different thickness gaskets, the fsm shows how check the end clearance.Bulltear sells em too

 

Got the gaskets and everything from Bulltear. No need to check the clearance cause there is none! : ).

 

You can measure how far out the gears stick and get a thicker gasket to put the end play into spec.

 

The gears will sit proud of the housing when assembled. The clearance between the oil pump cover and the gears is determined by the gasket thickness, and is less than the gasket thickness - ideal clearance using Plastigage is 0.002". Basically the clearance should be as small as possible without binding the gears. This is covered in great detail in the TSM - I suggest you study it - installing the pump correctly is important for good oil pressure!
