1968 Indy 500 Special help

[atbinkowski 13]

Hi all!

 

I'm new to the board, been lurking around a bit. Earlier this year I decided to do away with newer lawn tractors and buy something more Marine-proof. I picked up a C-175 and an Indy 500 Special as a combo deal (really only wanted the C-175, didn't know the 500 was a 500 until I started searching on here). The guy I bought them from had them sort of restored - mostly painted over and engine tune up type stuff. The 500 seems to be all original, included the hard sought after H60(?) engine. The crux is the mechanic sheered the driveshaft bolt off the engine. I'm wondering if this can be fixed if I farm the job out? I'd really like to get the Indy back to as original as possible, if possible, using it as a full restoration project my son and I can do together.

I'll try to get some pictures up as well.

 

Thanks!

 

Tony

Please do load some pics - will be helpful...

 You may be able to drill the bolt & use an easy out / extractor to remove it. Pictures may give us a better idea

Ever wonder why they are called easy outs???  They aren't easy and frequently don't get the bolt out.  (and if you snap it off the project get to be even less easy!!)

@Racinbob is somewhat of a 500 specialist but he is going to want to see  of it!

Sound familiar Dan!!?!?

[Racinbob 11,044]

I love 500 Specials. Starting with these two tractors that were given to me. The 500 is in the backgound. The closest one is a 657. 

 

 

I used the salvageable parts from both of them to make this.

 

Yours will be a great father/son project so please do post pictures along the way. 

 

 

Obviously it's not factory correct.

Welcome to Redsquare  Tony!

Once we get figured out what you need.... I might even be able to help you out.

[Pullstart 62,790]

 Tony!  I am not certain, but @bottjernat1 had a bunch of N.O.S. Tecky cranks... maybe he could help with a new one if needed?

I think his were all Big blocks.

 

I may have some spare parts thanks to @Stepney donating some engines to me.

Drive shaft bolt?

Yeah, we're gonna  need a pict of that.

I have found that the square easy outs work better than the spiral cut ones. But I agree it ain't always easy. If you heat the broken bolt up, it is a great way to ruin a perfectly good easy out tool.

I have a few NOS Tecky parts, I'll chime back in once we understand what you need.

Amen to that.Only time I ever had any luck with an easy-out was one time when I over-tightened a bolt and broke it off.Rusted in bolt???? Forget about it.

[Tractorhead 9,064]

Tried some of the so called „easy out‘s“ mostly without much success.

 

If i have hardly stucked or rusted bolt’s they restists every try of loosening and if nothing seems to help, 

i simply drilled it out fullsize re- thread one size up and put a helicoil in to have it back in original size.

That’s the easies Way i did for years with best results,

but that‘s just possible if enough flesh is available in Material.

 

a broken easy out can stop or even ruin your Project.

funny you should mention that. We had a customer who used to heat the square easy outs so hot the temper was out of them and he would twist them so much they looked like the spiral ones. Then he wanted them warrenteed!

Sorry it took some time to get back to this. Thank you all for your responses! I've attached some pictures. I think I meant to say the crankshaft bolt, not driveshaft bolt. I've been playing musical engines between my snowblower, wood chipper, and 500 this week. Engine on the wood chipper wouldn't start as soon as I got it home (ran just fine at the guy's place I bought it from...go figure), the engine on the 500 was back too far to use the deck I just bought, and the snowblower was the donor engine. Finally got the 500 all set last night after a second trip for belts and come to find that it cuts sometimes, smokes the belts other times. I'll try to figure that one out tomorrow (have woodworking to do today).

 

Anyways, back to the subject. There's a local guy who restores older equipment, and I'm considering using him to fix up the engine, but winter is coming, so we'll see. I've been known to mess things up more than they were to begin with, so considering the safer and cheaper option

That looks awesome! Both my Horses seem in good shape to start with. My C-175 leaks hydraulic fluid/oil though - pretty certain that's coming from the hose. I'll track that down one of these days too.

This looks like some one used an impact wrench to turn the engine over.  Note: you can put a socket on a drill and use it on the fly wheel nut to turn the engine over but never use an impact wrench to do this. The picture above shows the results of what will happen. The end of the crank shaft is broken off. Unfortunately, the only cure for this is to replace the crank shaft.

If this was a mechanic that you paid, I would ask that he repairs his mistake.

atbinkowski  The HH60 is harder to find than the H60. I think you can find a motor for parts or go e-bay or craigs list. Face book market place. I think an old snow blower engine would  may work?

School me here Dan are you saying one should never use an impact to remove or install the nut?

There's a special tool for removing the flywheel on those Tecumseh engines. It's basically a long nut.

The crankshaft nut itself can be removed with a breaker bar while you're holding the flywheel still.

 

[pfrederi 17,664]

You can use an impact wrench to remove the flywheel nut.  However there are torque specs for installing so you should only use a Torque wrench to install. You need a strap wrench to hold the flywheel not a screw driver in the fins.   Interesting on the small B&S engines there is a special took that hooks on the fins but uses a couple of them to hold the wheel.

I'm not saying that you can't use an impact to remove or install a fly wheel nut. I use an impact to run the fly wheel nut on all the time, but just to snug it. I then use a torque wrench for proper torque.

 

When I have seen the scenario pictured above is when some one has used an impact on the fly wheel nut to spin the engine over. Like to check for spark with out putting the fan shroud and recoil back on. This practice can be done if you use a drill to spin the engine over but the use of an impact for this purpose will almost always end up with a broken crank shaft.   

[atbinkowski 13]

The damage was done before I got it, otherwise that's exactly what would have happened. So I need to find a new crankshaft - how easy/hard is that for one of these old engines?
