Cat d13000 power for my new circle mill

RockyMountainSawyer · April 22, 2010, 09:10:40 PM

Just wondering on some specs on my new mill. My brother in law and I are triing to peice things together here and are at somewhat of a stand still. We picked up a cat d13000 for power and need to know the rpm range so we can order the pullies, belts, and have the saw hammered accordingly. is anyone here familiar or at least be able to point me in the right direction? :-\

I'm thinkin the governed speed is listed on the data plate. 1000 - 1200 rpm most likely. Might want to poke around over at the Antique Caterpillar Machinery Owners Club http://acmocbb.org/ACMOC_BB/

When I brought flat belt drive my Belsaw M-14 home two years ago, it came with an Oilver Super 88 diesel engine with no tach. I downloaded a copy of the Stanford Lunstrum saw mill book and went to work converting to flat belt drive to V belts and pullies. The book has all the information you need on pulley and belt requirements. Also he has an very simple math formula to figure out your pulley size and speed. To check my math I bought an inexpensive photo tach to dial in my engine for the blade rpm I needed. The Oliver engine governor is at 1700 rpm, I run the engine at 1450 rpm for an end result of 550 rpm at my 40 inch blade. I was able to find most of my pullies at our local family owned saw mill in town. Beware of made in China pullies from surplus centers. They only have two bolts holding the split hub adapter and are difficult to align when installing. Good luck.

Rocky MA,you couldn't have found a better mill diesel,its about 128 hp @just under 1000 rpm's It will just loaf along all day at nothing above an idle.To figure pulley size I would use engine speed of 900 rpm and go with "V" belts C or D section 5 or6 of them you have alot of torque to deliver.Frank C.

Frank That diesel sounds a lot like me, just loafing along just above idle. Steve

RMS,

We have a D13000 here with the drive pullies on it. If it would be of any help, I can measure them, but the mandrel and driven pullies are in Michigan. Maybe Corley 5 would measure them.

How much do you figger that engine weighs and how did you load and unload it? Corley and I would like to know ;)

RockyMountainSawyer · April 23, 2010, 11:05:31 AM

thanks for all the info guys i new i came to the right place with this. we loaded it on my gooseneck trailer with a 6000# hyster, it has to wiegh somewhere between 5 and 6k. We are going to go rent a gradall to unload it and position it. The guy that i bought it from said that it governed at 950 rpm, b ut he also said that his blades were hammered to 900rpm. his math was not sound because the pulley on his d13000 was 16.5'' diameter and the pulley on the mandrel was 25''. If i did the math right then his blade should have been hammered to about 600rpm or so. so either he was off on the engine rpm or the blade, what i'm getting at is i don't want to order my pulleys from six states away on an "i think so". so thanks bandmiller ;D, the local cat dealer didn't even know. :D

bandmiller2 · April 23, 2010, 02:11:30 PM

Rocky,seeing as you have the flat pulleys all set up would be folly not to use them.You are probibly correct on the 600 rpm hammered speed the math works out to a little over 600 figuring some loss when in the log, your right on.My first mill had a cat d 318 not as massive as yours but I had nothing to lift it, made wood skids and dragged it to the mill with a tractor.Frank C.

RockyMountainSawyer · April 23, 2010, 02:24:11 PM

Bandmiller,

Didn't mean to confuse.... the guy i bought the engine from is running a seperate d 13000 on his corley, this one was his spare. I got my mill elswhere, not a corley. i will try to upload some pics, they should help ;D

bandmiller2 · April 23, 2010, 02:36:54 PM

Rocky,you didn't say the diameter of your saw,probibly 600rpm would be a good speed to have it hammered for.If you don't have belts and pulleys "V" would be the best.On a new mill/new sawyer its good form to start with a newly hammered saw with at least new bits that eliminates alot of problems.Frank C.

RockyMountainSawyer · April 23, 2010, 03:19:35 PM

ok i have posted pics before. how do i drag photos from my gallery to here >:(

RockyMountainSawyer · April 23, 2010, 03:27:10 PM

I agree, i have a 50 inch 44tooth hoe blade 3 pattern 8 gauge. I am going to send it to Missoulla Saw in Montana, they are the closest saw doc that dosen't speak out of both sides of their mouth. Rod is who i talked to and everything we have discussed has referenced almost perfect with the circle saw book i downloaded "circular sawmills and there efficient opperation"

Doesn't this look like fun 8) 8) 8)

Sorry for all the random posts, i'll figure it out

I cant figure out how to free the head blocks and setworks up?

RockyMountainSawyer · April 23, 2010, 03:58:35 PM

sorry for the poor pics, does anyone know what kind of mill this is? We are triing to get these peices freed up, and we don't want to break anything :

bandmiller2 · April 23, 2010, 08:49:32 PM

Rocky,the best way to free up those headblocks would be to take them apart and clean them up.If you don't want to dissassemble loosen the bolts and tap with a soft hammer and copius amounts of weasel pith.If the pieces were smaller muriatic acid desolves rust and won't hurt steel and cast.Frank C.

RockyMountainSawyer · April 23, 2010, 09:56:29 PM

Thanks Bandmiller,

I totally forgot about muriatic :

Also is that cat engine max rpm 900 or is that just the range ideal for a sawmill????

barbender · April 23, 2010, 11:50:24 PM

Those aren't poor pics, don't be sorry. That is looking like a nice set up.

bandmiller2 · April 24, 2010, 07:16:27 AM

Rocky,I think its governed speed is around 950 but when your down around that speed give or take a little dosen't matter much.Probibly 900 would be a good place to figure from.Is your pony motor horizontal cylinders or verticle,or do you have electric starter.??Frank C.

Norm · April 24, 2010, 08:12:45 AM

I agree, good pictures and some beautiful country in the background.

Can't you just see those horses milling around thinking "boys were up against some big competition there".

RockyMountainSawyer · April 24, 2010, 11:30:41 AM

morning,

The pony motor i think vertical cylinders, with a crank start. If i had my way the mill would be truely horse powered, i'm really into the old fashion stuff. But my better half seems to think that would be to slow, and far more expensive.

Bandmiller,

I'll order my pulley then on monday figuring for 900 on the cat and 600 on the mandrel, thanks again. Hopefully I can get all this put together in the next two weeks! ;)
