1926 Thirty Project

It looks like your off to a good start, The Thirty is one of my Favorite

Made a little more progress this weekend, got to spend a little time in my friend's machine shop. The water pump/magneto/governor shaft on my machine was completely shot with rust pits and massive grooves where the packing glands were so I decided to just start off new. I found a piece of 1" polished stainless steel shafting and built one out of that. The sliding sleeve for the governor which rides on the peg on the end of the shaft was also completely shot so I built one of those as well. Now I just have to get the remainder of the old shaft out of the impeller im thinking the easiest thing to do is going to be to machine the old shaft out of the impeller since it looks like its pretty well rusted in place and im afraid of breaking the delicate looking impeller in the press.

Finally got the crank gear pulled off today and got the crank fished out of the block and after further inspection I'll need to re pour all three main bearings as they all have some pretty serious cracks or porosity. Since they're all a removable shell I've decided the easiest route to go is to create a mock up shaft and pour them on the work bench.

Hello again everyone, slowly but surely making some progress. Got the block back from the machine shop they hot tanked it for me to get all the goo out of it, the wrist pin bushing in the number two rod was loose and the bore was worn egg shaped so theyre truing up the hole for me then ill need to make new bushings for all four rods. Still hung on pouring the babbit though since its something im not familiar with doing, supposedly the shop thats fixing my rod can pour babbit if thats the case im thinking ill let them do it and ill just scrape them in. I did find a correct mag Bosch ZR4IS on ebay has a good hot spark. I tore into it to clean it up and found the ball bearings on the armature are shot and a few of the springs inside the impulse mechanism were incorrect so I ordered all of that from Mark's magneto service, knowledgable guy and fast service. I also did some scrounging on ebay and bought all the ball bearings I need thus far for the fan drive and for the clutch disc. I talked to a shop called All Friction back east about re-lining my drive clutch plates they figured around 80-90 dollars per plate does this seem fair? Is there any particular shop you guys like to use for brakes/clutch?

This inquiry commes up once to twice a year. Usually boils down to using a local one that someone else had good success with. I do believe in the last discussion on this that one in particular was recommended as they claimed to have "Original Dimension Specs".

I had rod bearings poured for me at a place called Antique Engine Bearing Service in California. He mainly does Ford flat head V8 stuff if I remember correctly.

I had to ship them the rods and old bearings, they did a great job. The guy was a bit nervous about doing the job without having the crank to measure himself. But I measured them and they were spot on to what I measured.

For main bearings though, I'm sure they would want the block so he could align hone. But you'd have to call them.

If I were going to try something like this, I'd send him both shells and measure the inside diameter of one of the other main bearings when bolted in the block. That way you could get them as close to the same size as possible. I don't know how critical it is because Cat gives you a ton of clearance and still be in spec.

Oh and the price to get the bearings done even with shipping was slightly cheaper than new Cat.
