When you did the work on the 471, did you have to remove the crankshaft pully?

Yes. The mechanic did it though. I watched him, but don’t remember that well. I could call him for you, but I bet someone here will know.

 

[Rustyfender]

Thanks for the offer, but being as there is no hurry , I would imagine we will hear from someone who knows.

 

[Rustyfender]

OI finally found some information on. This and it seems simple. Enough, pully is on a straight non tapered hub with a woodruff key, seems itshould pull off and damper iebolted to crank with 6 " special bolts"

 

[Rustyfender]

I must learn to proof read before I hit send,

I remember two of the half round keys.

Do you notice any difference in power with a turbo engine? There is one up here I am going to look at tomorrow

 

[mountainguyed67]

I never had a fresh non turbo to compare it to, but I’m definitely happy with the big increase in power.

It’s covered in snow right now. This is a friend’s picture from six miles away, and 600 feet higher elevation.

 

[Rustyfender]

Yes there is a lot of snow there, we have no snow on the ground, it comes and goes

 

[Rustyfender]

I went and looked at that engine today ( 300 miles on my truck I will not get back) but I left the engine there as it was going to Be to much of a nightmare to get everything hooked correctly.

 

[mountainguyed67]

More ordeal than mine?

 

[Rustyfender]

More ordeal than I care to do. This loader I have has seen better days, but it is still repairable

 

[mountainguyed67]

I was working on the tilt cylinder yesterday. These are the old parts, I didn’t get a fresh picture. The seal in the middle is too wide to go in there, one side wants to stay raised. I since measured the groove width at .246”, and the seal width at .271”. That’s 25 thousandths interference. Doh! I should have checked the parts people’s work. I can check the local place I usually go to tomorrow. In the beginning they said they stock it, but were out of stock. I can see if they restocked, and take my calipers with me. I need to go there anyways to get o rings for the hose fittings.

Just trim it down

 

[mountainguyed67]

Just trim it down

With?

 

[DMiller]

What are you compressing it with? These will require Squeezing to get them into the barrel. I used Aluminum Flashing pieces and hose clamps.

 

[mountainguyed67]

The chamfer at the beginning of the bore has been enough in the past, I wasn’t planning on doing anything else.

 

[DMiller]

There are actualy Stuffer tapered tools to install these and the Chamfer at the end of the barrel I have not ever had luck getting Gland Seals past.

 

[HATCHEQUIP]

25 thous. belt sander , grinder, file , or a sharp pocket knife either way will work . Had to trim many over the years to get to fit for oddball sizes or when we couldnt get the size we wanted

mountainguyed67 I just read through the entire thread. Man you put a ton of work into that old loader. But now I am sure you will have a machine to last a lifetime. Thanks for taking me along on the journey. I learned a ton of good information. Thanks.
