How do you guys deal with worn shaft holes in the hogshead? Only thing i can think of is taking it to a machine shop and having bushings installed.
If you buy new shafts and they're loose in the holes, that's about all you can do. I suppose you could make some bigger shafts, but that'd be a lot more work.
I can't find the part numbers right now but you can have a machine shop index the hogshead and put bushings (and an outer lip or O ring seal) in. If you have access to a milling machine with a 90 degree attachment it is not hard to do.
Paul...Ive seen the O ring in one of the parts books..Snyders i think.
11/16 drill rod makes an oversize shaft, then ream the hogshead. BTDT many times for a good fit.
I bought a 0.005" over size shaft from Snyders and It worked just fine after reaming with an adjustable reamer.
The reamer worked just fine in the cast iron. Much better than trying to ream brass by hand.
Pretty sure about the 0.005" , but at my age, the memories don't always match reality. It might have been a little larger, or maybe a dream.
Would brass/bronze bushings be to soft ?
If you do buy new pedal shafts be careful about the new clutch pedal shafts. Some are not made right.
Bushings and seals.
Herm...did you use bronze bushings?
They Were Brass.
I have always used Brass.
Herm, why use brass? Wouldn't bronze last longer? Just curious. Dave
Why would it matter, would any of us live long enough to wear out a rebuild of brass or bronze!
i could not find anyone who would machine and install bushings but that would be what i would do if it was an option.
Jim Weir, If I buy 0.005" over size shaft from Snyders does the pedal hole on the pedal has to be made larger also?? or does it remain the same ?
just wondering, for I have a set that I can do
Thank you Lorenzo
Yes; The hole must be reamed. I have a set of expandable reamers. The cast iron reams much better than using them in brass.

I don't know Dave, I have never had any wear out.
The one"s I use are cast Brass.
Don't use Oil lite.
Some time ago I posted about reaming alloy covers to accept bronze bushes and proper oil seal as Herm shows. I have never done the same on a cast iron cover, but can see no reason why it would not work. The bushes I use are a stock item available from our bearing suppliers. The shafts you have available from the vendors are also stock items. The seals I use are available to you in the USA. A very helpful forum poster sent me a small supply.
All you need is the adjustable reamers and a fly cutter to seat the seals. The pedals remain un-altered. The shafts are un-altered. The appearance is un-altered.
Altogether a most satisfactory re-build.
Hope thie helps.

Yes, you can do all Hog's heads.
I use a series of sizes, and lengths of solid reamers, end bore type, for the holes, and seals counter bore.
I hand ream the Brass peddle bushings for a shaft fit that just with out drag.
The high speed shaft on cast iron heads I bore all the way through and I leave the bushing stick out and plug with a cup type soft plug.
The blind hole just didn't work for me.
We have rebuilt all the hog's heads on the engines we have done.
