Project 320-8...A vision...

[HorseHead1089 100]

Well,today I painted the frame and other such, I guess ive finally made it to two pages! Hopefully assembly will take place soon....for the gear drive,  the engine pulley is 5.5 inches correct?  Because I have to order one for the huge crank on the 20 hp mag.  Edited October 13, 2015 by HorseHead1089

Should be pretty cool when done. But dude, you got no shoes on? 

[HorseHead1089 100]

haha, for the shoes part I uassually go take pictures after I'm done working, I don't work without the foot protectors. this whole picture rotation thing bothers me. Maybe one day I will figure out wich way spits them out straight.  Edited October 13, 2015 by HorseHead1089

Hello Horsehead,
Nice work on the tractor. regarding the picture orientation open the picture in picture viewer and then rotate it to the way you want it and save it again.

[HorseHead1089 100]

I've been doing some research on pulleys,  and I can't seem to find one with a 3 3/8 bore and the diameter for the gear drive, maybe I can get a 6 inch in there without modding the tins? Any help on tracking down pulleys and pulley size info would be great.

[HorseHead1089 100]

Wow... just some snooping around, it looks like the 8 sppeds require a 4 inch not a 5 inch is that correct? I dont know why i thought it was that big, can anyone confirm a 4"?

[Thor27 803]

Yes 4".      With that said....Require is such a strong word. you could go bigger, especially with a M20.

[HorseHead1089 100]

Thanks, now it just down to finding a right size pulley with the right size bore, with setscrews or some sort of separate locking collar?

[bmsgaffer 2,046]

I tried to find it, but didnt... What size is the crankshaft on your M20?

 

[HorseHead1089 100]

The crank measures out to 1 3/8 of an inch.

And I found a 4 inch with a 1 3/16 bore in the pulley, however it is still to narrow...

[bmsgaffer 2,046]

Can you take a stock WH pulley to a machine shop and have it bored and re keyed?

a 4" pulley is stock on the 8 speeds but you can use a bigger one, it will just make you go faster...

Grainger has a 1 3/8 ID X 4 1/4 OD double groove ( # 3X449 ) Go get it!

Right on 953! Thanks for that,  I assume a 1/4 inch will not change the need for a stock belt?

[bmsgaffer 2,046]

You should be alright, the clutch on an 8 speed helps make up some of the difference if its minimal.

Motor Mount has arrived!!! now onto doctoring up the motor and some other odds and ends while i wait for my stuff to get back from the body shop.

now back to the Homework...

[HorseHead1089 100]

It's been a long week of school, but due to buying parts like a madman I gotta re route time from the 320 to other things like my 10hp K series and some craftsman I picked up for cheap to sell later. Well that's in the shop today so I guess that's the first order of business. I also mounted up the motor plate on the 320, I can already see that 20hp bulging out the side of the narrow hood.

[HorseHead1089 100]

Quick question before I go get more parts, what is the easiest way to strip paint from a carb, or do you guys prefer painted carbs?

[bds1984 1,453]

I've used the gallon can of carb cleaner one can find from most auto parts stores. It comes with a basket that you can set parts inside to soak. I've submerged entire carburetors in it and allowed them to soak for a few hours before I was able to take a nylon brushe to clean off the paint on the carb body.

[Thor27 803]

Is that a NEW motor plate?

Partstree?
 

[HorseHead1089 100]

Yes it is, no one felt like selling one on ebay and I didn't feel like making one so I just bought a new one. It's bolted down with brand new Shiney stuff I'll get a picture tonight. Also bought this on sale 6/12v with auto charge rate and float maintainer/trickle charge has wheels and range of options from sears I throw some more pictures up of this as well.

[HorseHead1089 100]

Well that's the brand new motor mount, and there are more pics of the new battery charger. Also that 10hp K series is currentley up for grabs if someone feels like making an offer.

[Aldon 4,827]

Looking good so far. New parts are nice luxury on occasion.

Looking forward to seeing the 320-8 finished

[HorseHead1089 100]

Yeah me too, it may take a while because he offered to do it for way less than full price if I didn't need it done right away and I could wait after some of his higher pay jobs got finished.

[HorseHead1089 100]

Ok,  so in the pto of a wheel horse, there is a sleeve,  that goes over the crank, and under the needle bearing of the pulley cone,  what steel is that made out of,  I'm looking to have it turned or order a new piece of metal stock for the oversize crank of the m20, I figure it would be easier to try this than to immediately rip the crank from the motor and turn and re key.

[HorseHead1089 100]

Well 4 pages deep and several months since an update, I bet you guys thought I gave up! Nope, in fact it's been real exciting. That quick flip of a craftsman turned into an engine rebuilding nightmare and that was not fun. I have yet to sell that sorry piece of machinery. On the 320 front, we have the parts sandblasted and painted from the shop done, and now ready to put back together. As far as the motor, no progress has been made on it since I have had barley anytime to work at all! Now I have her resting on all fours and I just need some cotter pins and other hardware. This has been quite an interesting build so far!
