Help with 2.0 Crankshaft Pulley
« on: January 24, 2020, 09:44:05 PM »
The head gasket on my 1972 2.0 wagon started to leak and it's time to replace the timing belt. My mechanic is having trouble removing the crankshaft pulley and is concerned that he might damage it. Before he proceeds further, he wanted me to ask if there is a source for a replacement pulley. He also wanted to know if there are any tips to remove the pulley. As the head was resurfaced in the mid 90's, he also wants to know if there is a source for a new one. He is trying to prepare for a "worst case scenario." Any help/ suggestions would be appreciated. Thanks!

The pulley should come off pretty easily.

Someone here should have some spares.

if not try Racer Walsh
904 721 2289 or
904 721 3177
And ask for Brian he is one of the few sources left and is in florida

Also, before you remove the belt have the mechanic mark the camshaft pulley to make setting the cam timing easier.

There are marks on the pulley backing plate and head but they arent accurate andnit is possible to get the cam timig a tooth off either advanced or retarded.

Heres a pic of how i did mine.

I turned the engine until the top dead  center "0"  timing mark on the crankshaft pulley aligned with the pointer on the engine block.

I then used a hacksaw to cut a small notch in the sheet metal backing plate behind the cam pulley that aligned with the center rib on the cam cover.

That way its pretty easy to realign the cam and crankshaft by lining up the notch with the rib in the cam cover.

Also make sure that the rotor in the distributor is pointing at the small.hash mark in the distributor indicating cyllender no.1.

You might also consider installing an adjustable cam pulley to.advance the cam about 4 to 6 degrees.

This will improve the low end performance quite a bit and if your cyllender bead has been machined during a valve job the cam timing may be affected

An adjustable cam pulley wi.allow for optomizing the cam timing

 Racer Walsh can get one for you, just request a STEEL one not an alloy

If you decide to.install the adjustable pulley i can provide you with some useful info as to how tk advance the camshaft.

Also a pertronix electronic ignition will improve performance and reliability.

I posted a post here about how to do it.

First Photo shows notch in pulley aligned with rib.

Second photo shows detail.of notch.

BUT note that in the second the notch is NOT aligned to.factory setting but with camshaft advanced about 7 degrees.

In factiry setting the notch should be exactly aligned with senter rib.

As far as getting a new head, if yours isnt  cracked and you are doing a valve job just keep the one you have. They are getting pretty scarce

Just have a valve job done and have hardened seats installed

Having one that has been machined before can be a good thing and it can actually provide better performance.

A 2.0 head can easily be machined .040 and will provide better compression, about 9.0:1 vs the original 8.1:1

Every .040 inch machining will raise compression about 1 point

The 1971 pintos had 9:1 compreszion and made 100 hp in 72 and 73 they reduced the compression to 8.1:1 and the horsepower dropped to 87.

I cut mine .040 and can still run 87 octane with no problems

BUT as in previous posts machining the head will affect the length of the cam to crankshaft pulleys and make it difficult to get the camshaft timing correct

An adjustable cam pulley is about $120 and a really good investment to optomize the cam timing.

https://www.burtonpower.com/kent-cams-adjustable-steel-cam-pulley-ford-sohc-pinto-ft310a.html

Racer Walsh can get it for you

Also again consider a pertronix ign module about $125

https://www.amazon.com/PerTronix-91847A-Adaptive-Aftermarket-Distributor/dp/B000N2U5TG

Pinto uses a bosch distributor similar tk the volkswagon

They fit into the distributor and replace the ign points

l have 2 used adjustable cam pulleys, $50 ea. 2 small performance aluminum crank pulleys, $30 ea. and a Mallory Unilite distributor w/ cap, rotor, wires and a spare module, $75. + shipping.
The best thing you can do to ANY 4cyl Pinto engine is set the cam timing. They were typically 2-4 degrees retarded from the factory so when you surface the head .040" you end up 8 degrees retarded and it runs like a slug. Advance that puppy 2-4* ATDC and you won't believe the difference!
If you don't have time to do it right, when will you have time to do it over?

I second the lrevious post

Ford retarded the cams in all their engjnes in the 70s so advancing is a must.

But i have had both an alloy cam pulley and a steel one.

For street use the alloy one wore out in about 5000 miles, dont know why.

So i switched to a steel and it really made the car come alive.

Take 71 pintoracer up on the parts he has and you will be surprized at how much better yiur car will run.

71 pinto racer,

Is the advance curve adjustable on  the mallory unilite.

I reworked my factory distributor to have 16 degrees centrifugal advance starting at about 2000 rpm.

 locked down the breaker plate and removed the vacuum advance and set the initial timing at about 14 degrees  to get about 30 total.

That helped a lot as well.

Thanks for the suggestions. Monday I will pass along the tips to my mechanic. I doubt the head can be resurfaced. When the engine was rebuilt in the mid 90's, the head was planed and a casting defect was exposed so it had to be done again. As a result the head was a bit low and two of the timing pulleys had to be switched. In all these years it has never caused a problem. My current mechanic knows the timing marks can't be used and times it by "ear." The shop I use has an excellent reputation and over the last 4 years they have taken good care of my Pinto. They know my dad was the Pinto's original owner and that I will always keep it. Thanks again for your help. I really appreciate it.

LTFM the Mallory is all electronic and has 24* of advance, so at 10* initial you get a total of 34*. lt always worked well for me.
72 Wagon l'm a little confused about "they had to change two of the timing pulleys." And cam timing and ignition timing are totally different. l have "tuned" timing by ear lol but a mark at TDC and an advance style timing light are all you need.
l have 3 stock heads and 1 complete that has been cut .060" with a Motorsport Racing cam.
If you don't have time to do it right, when will you have time to do it over?

I have limited mechanical ability so I probably am not explaining it very well. In 1995 the head was planed twice. When the block was reassembled the top timing pulley was too high. The mechanic switched the two timing pulleys because one was smaller and cleared. That's the best that my husband and I can recall. Since then, the car has been lightly driven and always ran fine. The past 4 years, Russ, our mechanic, and i have been working to gradually address various age related issues and the timing belt was at  the top of the list for this year. That work led to the discovery of the small leak in the head gasket. Again, I appreciate all the help to keep my Pinto on the road. We live in a small, rural community and everyone knows who drives the Pinto!

Are you describing the timing belt pulleys. And what do you mean by "too high".

Do you mean too thick so that it rubs on the cover or too large in diameter.

There are 3 timing belt pulleys on a 2.0.

A small one on the crankshaft, the one on the camshaft and one on the au,ilary shaft on the driver side of the engine.

The cam pulley and auxiliary pulleys are the same so if one fit the other should as well.

HOWEVER it is possible to put the pulleys on backwards, that is facing the wrong way.

This not only affects the timing but as well can interfere with the belt cover..

Here are some pix of the pulleys.  They are identical but showing both sides.

Note the balance "bumps" on one side on the blue one

If installed properly the auxiliary shaft pulley should have the bumps facing inward as in the brown pulley.

The cam pulley should be installed with th bumps facing forward like the blue pulley

Its also.possible to not install the belt cover and if you have an adjustable cam pulley its probably more convenient without the  over if you want to experiment with the cam timing.

It also looks.cool...

The 2.0 is a "non interference engine" meaning that if the camshaft belt breaks and the cam stops but the pistons dont there is enough clearance between the open valves and the pistons to prevent damage.

Normally the valve timing prevents the valves and pistons from colliding.

Not sure how much you can actually skim off a head without the danger of having the valves hit the pistons,

I suspect that .060 might be the max but perhaps 71PintoRacer has an idea.

It is also poss8ble to measure the thickness of the head to find out how much it has been machined

If your mechanic needs assistance i can pm you my phone number so that he can call

Also as 71 pintoracer wrote you can adjust the ignition timing by ear.

BUT you cant really set the cam timing "by ear" without an adjustable cam pulley.

The only option without the adjustale pulley is to move the belt one or more cogs forward or back and this is WAAAYY to much for the engine to even run.

One cog is about 18 degrees and you need to adjust to about 3-8 degrees and then need to stop the engine and remove the belt.

With the adjustabke pulley you loosen the adjustment screws, turn th3 crankshaft a bit and retighten.

Not to change the thread but just thought you might want to see my  ustom manifold.for 2 SU HIF4 carbs from a 72 mgb. Setup improved performance drastically over the stock weber.
With stock cam, pertronix and the carbs engine spun easily to 6000.Havent wanted to run it farther.

Very Nice! Looks really good! 6000 rpm is nothing for these little engines, they will go 7k without a whimper in stock form, with a little bit of tuning, which you have for sure. Cam timing is critical to get these engines to run good.
If you don't have time to do it right, when will you have time to do it over?

Well tbis is a fresh rebuild .060 over bore, forged pistons, stock cam advanced about 8 devrees, head cut .040.stock rods.

I wanted low end torque for cruising so 6000 rpm.is plenth for me. With this setup it starts making power about 2000 and easily revs to 6000.

How many revs do you think the stock rods would handle?

The car only has 70k miles and i have the original engine stored for the grandkids. Just wanted a rebuild to drive around so i woulnd use up the original.

have you been to any of the stampedes.i did the 2016 to.carlisle, the 2017 to dearborne.and the 2018 thru the smokies. Maybe we have met

Not to butt in here, but you say you did the 2016 Stampede to Carlisle?  Did you participate in the pizza party at the Ford dealership on the last night before driving the final leg to Carlisle?  I hosted that event which, despite the miserable weather, was well received.  My Pinto wasn't up to the trip at that point, but I met up with the gang the next morning at the motel and joined in for the trek to Carlisle anyway, bringing up the rear, driving my red 2015 Mustang convertible.  Jimmy wasn't there for any of that, but it's highly likely that WE have met.  Small world!

Monday I dropped off the suggestions everyone gave to my mechanic Russ. Since my Pinto is in the "project car" category, Russ works on it when his regular repairs are done. Due to its age, Russ let's his crew do things like the oil changes, but only he and Charlie work on the engine. That way if anything goes wrong, Russ knows who is responsible! I'll post when Russ gives me an update.

Well then, I most certainly must have met you.  I'm pretty sure I made contact with all the attendees of the pizza party at some point that evening; or at least I tried to!  The weather really interfered with my plan there, but all things considered, it still went fairly well.  It was arranged to be an opportunity to show off the Pintos but the rain kept spectators from showing up.  Roger Aldheizer (the Sales Director there) did record an interview with Norm and post it on the dealership's website, so that was decent publicity for the Ford folks in the area to see and, while I provided the pizzas, drinks, and cake, it was he who made the dealership facilities available for the party.  Before we hit the road the next morning, I was in the motel parking lot trying to see to it that all the participants got a PCCA magnet but I'm sure there were a few folks I missed (if you didn't get one, PM me and I'll send you one).  Once we got to Carlisle, I really didn't hang around long.  The weather was lousy there too so I headed homeward after a couple hours.  My wife is severely handicapped from a stroke and, while I left her in good hands, I wanted to get on back home as soon as possible.  I already knew Norm, Louise, and Bev from the 2011 Stampede and I just couldn't let the 2016 Stampede have a stopover in my town without getting involved with it in some small way.
