Saylor Beall 705 Again

[Saylor Bill]

Hello---I'm new here and found my way via googling my new-to-me Saylor Beall 705 compressor.
I found a thread here from back in 2006 in which another fellow had also acquired a 705 and was trying to get it up and running. Turned out he had a broken crankshaft and the last post leaves us in suspense as to whether or not he he ever got'er going----but I learned a lot from reading thru the whole thread----including that there are some very nice and helpful people here.

I got my 705 thru an online auction and have had it around for awhile but now am serious about getting it running.
The seller claimed it was a good, running unit. They had damaged it slightly in moving it----bent the belt-guard housing a bit and squashed the copper pipe that feeds the compressed air into the tank.

I took the guard off and had to take the flywheel off to get at the back half of the guard. I've replaced the copper tube and straightened the guard.

My main issue: I noticed that one of the spokes/vanes of the flywheel---the one through which the bolt goes that tightens the flywheel to the shaft----has a hairline crack that goes part way through the vane/spoke near the bolt.
It looks like its been that way a long time and I've considered just putting it back together that way and hoping-----but imagining that heavy flywheel coming apart at 800rpm makes me nervous.

I'm wondering----could this be welded or brazed? or should I go for a new flywheel?

That 2006 thread mentioned a man named "JC Quick" who helped that fellow find parts-----is JC still around?


My shop is multi-purpose---woodworking, concrete art studio, vehicle repairs----I have a 1966 Ford F500 flatbed that I want to restore--etc.

Its a real education reading here---thanks to you All,

JCQuick is still here and was online 4 days ago. Hopefully he can help you out with your problem.

cast iron can be repaired. Personally i'd just JB Weld it or replace it. Saylor Beall is still in business and still has parts for their compressors and they will sell to you over the phone.

I had the same problem with a 705 pump I recently rebuilt. If it is indeed a crack, I wouldn't fool around with it and replace it. I purchased one here. The price was a bit higher, but they definately make up for it in shipping costs. Also, when ordering parts, you need to specify old or new style. The connecting rods, oil seal, and crankshaft are not the same. Good luck and have fun.

I agree with other posters. Replacing it seems to be a safe approach (though I endorse welding it, too). Flywheel Part # for 705 is 6445 (p.6 of link). Here is a link to the manual: http://www.nhproequip.com/PDFs/Saylor-Beall-700-Series-AirCompressor-Pumps-Manual.pdf good luck. Pls. let us know what you end up doing.

I finally made it to the nearest welding shop that does 'tricky' stuff. They said they can definitely weld the crack----but since it is so near the bolt that secures the flywheel to the pump shaft by squeezing the hub slightly-- they are concerned that the weld---since it won't flex at all MAY not be an effective repair---IE----MAYBE that spoke will crack behing the welded place when the bolt draws things up tight.
Any thoughts?
I'm looking for a used flywheel locally and thinking I'll go ahead and let them weld it ($75 to $100) and see what happens.
I only paid $250 for the whole compressor so hate to spring for a flywheel that costs several hundred....

(meanwhile my local craigslist has a guy with several quincy 325's (or qr25's) that he wants about $200 each for---I think it is the pump only----very tempting...)

These large flywheels should be balanced also or they could vibrate and shake everything apart. Add balancing to the cost of the weld if you go that route.

 

[oilslick]

I would go 325 and never look back only 200 each I would buy all several!!

You should be able to get a new flywheel for 160 shipped.

 

[Saylor Bill]

wow! $160 shipped?! that is from the place you posted before?

I assume you were happy with the one you got from them?

That sounds like the way to go---only 60 mor than welding it.

That would be the one. Get their number and give the guy a call. (real nice people btw) Be aware this is an import flywheel.....I actually liked it better than the OEM. (more air flow) Anyway, for an extra $60, I think this is the way to go, and you won't have that nagging thought in the back of your mind every time you use your compressor.

 

[Saylor Bill]

Thanks Kams!

I emailed them last night and have a reply this morning----$175 including shipping to my SC.
I think I'm gonna go that route.
I appreciate the invaluable advice and input of you all.

Before ordering a generic imported flywheel, did you check to see what Saylor Beall wants for the genuine article? Just curious - sometimes you get surprised and find out the real deal is actually cheaper.

 

[Saylor Bill]

Doh!

No, I neglected to do that. I pulled the trigger today with the guy Kams mentioned.
He is indeed a very nice man and very knowledgable (spl?) RE compressors.
He stocks some Saylor-Beall OEM parts in addition to the imports.
Its hard to imagine that an OEM flywheel could be less than a couple hundred---but you may be right.
I wonder if S-B will sell me stickers so's I can make my compressor look all nice and new?

Where are the pics?

 

[Saylor Bill]

Hey Kams!

I did get my flwheel from the man in Texas----I'm just now getting around to installing it---I'm not sure which way it should go on----which way the vanes should face---in fact I can't tell which way it would be blowing and which way would be pulling air----I assume one wants it to blow toward the pump not **** air the other way--?
anyway---how did you install yours---was the tightening bolt toward the pump or away from it? Help!
Also---did you do anything to open up the hub at all? I haven't been able to even get my
new flywheel started onto the shaft---very tight. I think the key might be too tall for the slot on the new flywheel too.
How much banging on the flywheel can you do without hurting things inside the pump?
should the flywheel hub be heated up?

Advice would be much appreciated.

Paint and stickers are no problem to get from them.
