My 302 Stroker Build

[Florian]

Update: Removed the rod and piston assemblies, positioned everything right and installed them again last weekend. Still waiting for the countersink to arrive so that I can prepare the new cam thrust plate.

Finally got the right bolts and could mount the thrust plate today. Then I test fitted the cam gear and it fits fine. End play is also good.

Then I continued with the timing set. After I installed everything I noticed that I have got too much slack in the new timing chain! I´m already in contact with Summit, we´ll see what they´ll say about it.

You can see it here:









Also what do you guys think about how I mounted the cam gear, without the fuel pump eccentric? I filed a small part off of the washer so that the dowl pin of the cam could sit properly. Is it okay like that?

Thanks!

Chain is junk when new, not a good sign for the future. Summit brand? What was the country of origin? Cloyes still makes a good part. The 1968 Ford manual says you can have a maximum of .500" deflection in the chain, looks like you are halfway there now.

The pin should be caged by the washer. If it slides out valvetrain catastrophy will ensue. The pins are usually hardened so you'll probably have to abrasive wheel the excess off. Just remove the cam and put it in a cardboard box with the pin sticking through a hole to keep the abrasives away from the machined surfaces.

Hey Jamie,

Yes, Summit brand. The set´s country of origin were the US though. Must have been some kind of production error. The tech guy from Summit asked if my block was line bored, that would of course explain the slack of the chain. I hadn´t it line bored and I think it wasn´t before as the cylinders were never bored before, so who would line bore a block and not bore the cylinders?

I settled with this set from Cloyes now, has billet steel sprockets and a premium chain.

Ah! So the washer needs to be over the pin to prevent it from falling out! I didn´t know that from when I disassembled my engine because my old pin was sheared off already..
I can just pull the pin out and grind a bit off of it, then it should be fine I think.

There won´t be an imbalance because of the lack of the eccentric, right?

Thanks!

A little update:

After I got my new timing set from Summit I found out that my cam pin was too short to drive the fuel pump eccentric. You can read more about that here: http://www.fordification.com/forum/view ... &sk=t&sd=a

Then I found out that they sent me the wrong timing cover bolt kit. Got new bolts and wanted to install the timing cover yesterday just to find out that the guy who balanced my crankshaft, sold me the wrong harmonic balancer. Its shaft is way too long to go on the crankshaft and make up a seal with the front seal.

I did not use a balancer installation tool, I gave it a couple of love taps with a soft hammer, because I didn´t want to install it for good and my neighbor from whom I can borrow the installation tool was not there. I just wanted it to align the timing cover with the front seal, so that the gasket and sealer that I already had on the cover wasn´t wasted, I hope it´s aligned correctly..

However, the new balancer is much longer compared to the old one and can´t go on the crankshaft with the timing sprocket on there, it must be the wrong one. I think it´s already in contact with the oil slinger and won´t go any further than that and still sticks out way too much. Can anyone identify the balancer just from the pictures?









The old balancer:






I´ll contact the guy who sold me the balancer and said it was the right one on Monday.

This is starting to really piss me off..it´s crazy, it´s almost every part that does not fit quite right or something. And it´s not even my fault.

Hope it´s getting better from now on...

The oil slinger has to go with a double roller timing chain. Pretty sure that's your 'problem'.

Lay both balancers on a table bolts down and compare the height. Take a pic and post it up.

Did you get a ring that goes on the pulley side of the new balancer to help align the pulleys? Notice the original has the stepped alignment ring.

Jamie

Hey Jamie,

I don´t know if it´s only the oil slinger. I checked the clearance between the oil slinger and the front seal without the gasket before I installed the cover and there was still some space left. If the slinger was the problem it would have rubbed against the front seal or not? And there is not enough clearance between the balancer and the timing cover if the balancer´s seal surface would be at the front seal.

I will remove the balancer and take some pictures for comparison on Monday when I can borrow me the puller tool from my neighbor. And yes I got a spacer ring to mount the pulley on the new balancer. I´ll take a picture of it too.

Florian

Check the width comparision between the old crank sprocket and the new one too. Somewhere in there the stack height difference will show itself.

Jamie

[Florian]

Got the balancer off again and took some pictures of it next to the old one.





















I didn´t want to remove the timing cover to compare the crank sprocket widths, so I compared the old one with the one from the wrong Summit timing set. The double roller sprocket is a bit thicker. The new sprocket seems to be the same width:






What would you do now? Does the new balancer look okay? Can the oil slinger stay?

Thanks!

Florian

[Ranchero50]

In the pics I don't see any terrible discepancies...

At this point I would put the new balancer on the crank with a little bit of oil on the crankshaft, torqued in place to eliminate any possible gaps in the stack, then mock up the water pump with gaskets (no sealer). Then install the pulleys for the water pump and crank and check the pulley alignment. The two pulleys are close together and everything else becomes moot if the pulleys are ok.

You're doing good, aftermarket parts can be a real pain to deal with.

That sounds like a good plan! Thank you Jamie!

Problem is that my neighbor bizarrely owns a balancer puller but not the installation tool I ordered a combined puller and installer tool from the US now. Hope it arrives by end of this week or beginning of next week with express shipping. PITA I can tell you..it´s like one giant trial of patience by now

I´ll keep you posted!

Florian

[Florian]

Hey all!

The balancer puller / installer tool arrived last Wednesday, but I didn´t find the time to mount the balancer until today..I´m having my final exams at school in two weeks

The balancer fits perfectly now! The pulleys line up just right









I hope I can get the bottom end finished this week
