Re: fuel push rod insert
 

Can anyone give me the size of the push rod bush hole in the block on 59A bush looks really thin need to punch it out.

Re: fuel push rod insert
 

i asked the question simply because there has been threads on this before about plugging the bush as the oill sprays up @ if i remember right someone said it can effect your oil pressure on a 8ba not a 59a or earlier

Re: fuel push rod insert
 

Bush was damaged when cam bearing was in stalled. The fuel pump push rod wont fit the hole too tight.

Re: fuel push rod insert
 

They are real thin new. Leave it alone. ken ct. There is no oil pressure down there,just a mist at best.

Re: fuel push rod insert
 

If the cam bearing damaged the pushrod bushing, what does the cam bearing look like now?? How did the pushrod bushing move downward into the cam bearing housing?

I believe my 59A bushing driver is .390 O.D. with a .360 pilot. Obviously the cam is out and the bushing is driven into the cam bearing housing with this tool.

Even new ones are NOT tight,there real sloppy. ken ct.

I had the same problem with my 37 block with the machinist installed bushing, measure the diameter of the push rod & use a drill bit the same size & coat the bit with heavy grease so it will pick up the shavings &VERY SLOWLY DRILL IT OUT. it worked for me.

Maybe i got it backwards,i thought you said it was too sloppy,no problem there. If its opposite dont know what to do about that.There impossible to remove with cam in place and too thin to cut thread in it to pull it out???? ken ct. Good luck.

Yes. It can be done, as long as we are talking 8BA. I won't get into the why of your situation, just how to do it. You need a quality 1/2" 20 tap. The bushing is very hard. You will have to put a lot of weight into the tap to get it going. Fill the bushing with grease, and it will catch any chips. Make a puller as pictured to pull it after you tap it.

The first photo shows the bushing on the end of the puller after it was pulled.

I know this topic has been discussed at length. I did not remove that bushing in my 8BA when i removed the push rod and it DID not lower the oil pressure. Other reports may vary.

Re: fuel push rod insert
 

Thanks JWL the size is just what am looking for. Not sure about the cam bearing. But the cam fits and rotates ok.

Re: fuel push rod insert
 

habbott.
Why not grind or sand a little off the sides of the rod on lower end??

Re: fuel push rod insert
 

I just mic'd a couple of used 59a fuel pump bushings, O.D. is .441 or so...
I put a 7/16 valve guide in the hole once, it fit well...

Re: fuel push rod insert
 

I have ordered a new bush, but it seems it may not be necessary after reading this?

My block is C69A, is this the same as a 59A and a possible worn bush will not effect oil pressure?

No point in fixing it if it ain't broke.

BTW, I found this thread on a search for how to remove cam bearings, but nothing specifically came up to answer my question.

Re: fuel push rod insert
 

The bushing will not effect oil pressure unless it is worn to the point it has a hole in it. There is no pressurized oil to the rear cam bearing so there is no pressure to loose. Pressurized oil flows around it in the main oil galley.

Re: fuel push rod insert
 

The push rod bushing on an 8BA does in fact have a hole in it to lubricate the push rod with residual oil lubricating the cam bearing and push rod lobe.
With the push rod removed you will loose oil pressure.

Re: fuel push rod insert
 

So I should be able to maybe feel down the bush and feel for any oil hole facing forward , in case an 8BA bush has been fitted, and if no hole and bush looks OK, leave it be then ?

The block is stripped right down ready to assemble when parts arrive.
