Here’s a pic of the fuel pump lobe counterweights against some machinist rules.  The counterweights are about 0.160” thick.

here's wishing everybody a happy and prosperous new year

i'm just back from the kids carrying an extra 7lbs weight    thats not good it takes months to shift..

Ted thanks a bundle for the counter wt. pics they scaled up good.   can't come up with any thing 160 thou with out surface grinding but 4 mm is only 2 thou shy and its off the shelf   gonna use grade 01 tool steel its a bit better than mild steel and i'm thinking it will be better for the keyway     now there's another problem. i think the key way is 5/32 and the bore is 1".  the only broaches i've seen are 5/32 B and the only sleeves of 1" do not go down to 5/32

any comments  advice??

thanks folks

Stuey:

The originals had to have been stamped.  Hand building them like you are proposing would have been too slow and expensive.  Even Ford must have thought stamped ones were too expensive and eliminated them.  Thousands of new car buyers never new the difference.  The use of tool steel would be overkill, they are clamped in place, there would be no load on the key. Are you thinking of producing them for sale?  It would be a very small market.  JMHO

just a stupid question, did they change the weight of the fuel pump cam?

 lincoln/merc. y-blocks &mel's                                                               bucyrus, ohio.

The fuel pump cam was changed in 56 when the dual diaphragm pumps became the norm and wear appeared on the outer surface.

The new cams were heat hardened. You can usually see a blued tinge to the cam when comparing to a 55 cam.

As to weight of cam I have never weighed one. Visually they look the same thickness

John  thanks for the comments

i have no intention of going into production  i'm a backyard DIYer who loves to have a go.

since getting the Y powered F100 i've mastered TIG welding (only in the down hand position)  replaced the drivers side floor    i've also learnt how to bend a new oil pickup tube using sand fill method      the first attempts tore apart but with a little patience it worked    all my existing pickups are well bashed    now i'm learning about broaches and keyways all thanks to the Y-block

a lot of info is on You-Tube from a gent called Tublecain all basic but good. home casting is on the horizon and home made headers

the truck came from Klamath falls Oregon and i've seen a couple of contributors on this site that may be from that area   the previous owner was Don Tidwell who also had a Y powered Morris Minor !!!

happy new year   stuey

On the smaller diameter holes, I typically have to build my own broach collars depending upon the key cutter being used.  Here’s a picture of a 5/8” diameter ‘B’ collar that inserts into a 1" diameter offset bored bushing for doing the 5/32” key slots in Y-Block camshaft timing gears.  And here’s also a picture of a ‘C’ collar machined for a ‘B’ cutter.

thanks for taking the time and effort to reply.

i'll go for the offset bush, i did find a Dumont 5/32 C broach at Fastenal for    wait for it       $236.88!! too rich for me.

now its time to knuckle down and do it

thanks a lot
