Morning all.
I picked up a 94 Dyna Convert a few weeks ago (my 3rd Evo) and started to go through her to fix up a few neglected things.
Replaced Front/rear wheel bearing and engine mounts, broken/loose bolts etc and the old girl has been running great.
Until last Sunday when it blew the front head gasket, well I got her home and last night had a chance to start pulling her down, found the top engine mount is shot so I will replace that.
You can see from the photos that two of the head bolts were loose, as in finger tight, also the blown head gasket, the heads/valves look ok but I will give them a clean up and re-seat.
The Bore and pistons look ok and you can still see cross hatch or hone pattern in the bore, but I did find I have adjustable push rods so I will be taking her down to cam level so I can check what cam I have and to see if the cam bearing has been changed, the lifters are quiet so I wont replace them.
A question....I there any way of telling what brand pushrods I have so I can adjust them correctly when I put her together again? I will finish tearing her down today and keep you informed with what I find but then I cant do much for 3 weeks as work is crazy at the moment.

Cheers.

 

Check your cases...the cylinder studs are bad to pull out the threads or crack the cases.

 

Will deff do that...thanks mate.
Will post up some pics of a pushrod shorty, hoping someone can identify so I know correct adjustment procedure when I put her back together.

 

Wow, looks nasty. Do they all do that, or only up to a certain year?

 

Not so much on 94 up cases.. I was told that Mercury Marine made the cases for hd. I believe 93 down....

 

Unless they are marked ( don't think my S&S were) best way I know how to figure it out is go buy a Thread Pitch Gauge.
Then you will be able to find out how many threads per inch are on the pushrod & go from there.
They're not that expensive & everyone who does their own wrenching, needs one in their tool-box.
Or, measure the overall length of one of the push rods, mark the adjuster & count the flats or revolutions until you lengthen the pushrod 100 thousandths

Ok, have her stripped down and cam out.
Anyone able to identify this cam? I have searched the forum and google with no luck
On one lobe It has FB326-2
Another has 19-92.
Plus the Stamped numbers in Photos.
Nothing on end of cam....

Cheers.

 

From what I can find, it looks like a Crane FireBall cam. 6th from the top.

 

Cheers mate...well there you go.
I was told by the p.o who was the 2nd owner that the bike was stock, but he knew stuff all by the sounds of it.
So I have adjustable pushrods and Fireball cam on a stock bore motor.

 

Are the studs ok? I was wondering how someone manages to get a head bolt (or 2) loosening itself. I snapped a back bone when I had to take my top end apart
