Anyone with Timber Harvester experience

Wick · February 11, 2013, 05:16:09 PM

When I disengage the blade on my 2002 TH30HT25 the blade continues to rotate.
It is not supposed to do that right!!????
Any ideas on what to check, adjust, or replace???

POSTON WIDEHEAD · February 11, 2013, 05:23:20 PM

Wick, I know nothing about your mill. Do you have a manuel? It sounds like the blade break needs adjusting if your mill has a break.

is that a jackson timber harvester? if so i think ron weinrich ran one. he'll probably chime in soon.

Wick,i have that mill,only older,a 94....

Do you have the right length belts,on this mill???

I run a 95 30HT.
Have you changed your belts, or adjusted the tension?
On my mill on the drive side there is a bar that directs the
belt onto the motor pulley. That bar keeps the belts from running
tight on the drive pulley. It may need adjusted, a little movement
up or down can cause the belts to run all the time.
When you disengage the blade it should coast to a full stop.

As Dutch said when belts are used as A clutch you will find some sort of guard or pins to keep the belt loose around the driving pulley.If you engauge the clutch,engine off,move the pins/guard so when you release the clutch the belts are loose around the pulley.You may need to fuss with it a little to get it just right without belt creep.

OK, so it sounds like what I was seeing. Basically the belts should "slip" on the drive shaft pulley until engaged. As for proper belt length, I will have to check them against the manual. I can picture everything you guys posted so we might be on to something, THANKS!! Maybe this weekend I'll get some pics.......Got to go to a meeting now ;)

I am on my second TH, a 36HTD25. Awesome machines...I miss them.
As mentioned, there are two pins mounted on the engine block, one above the drive shaft pulley and one below. If the belts won't stop, rotate the pins (a hammer will do the job) closer to the pulley to cause the belts to slack around the pulley. I am out of town right now otherwise I would snap a photo for you but it sounds like you understand what we're talking about.

Wick · February 13, 2013, 11:59:25 AM

Thanks, yeah a picture would be great. I think mine is modified and it only has the top pin. Actually not a pin in mine, more like an" L " bracket and don't remember seeing one on the bottom.
I hope to be able to brag on mine one day. I just recently rescued it again and hope to get it running correctly. >:( Long story but I'm about three years behind in this venture. Thanks again.

Hey Wick,what motor do you have on this mill?Maybe a pic. from you would help.....albert

Brad_S. · February 13, 2013, 01:45:48 PM

I will be home by the weekend and will get a shot for you.

Wick · February 13, 2013, 05:13:55 PM

I'll try some pics too, maybe this weekend. The motor I know is not original. It's a 2 cylinder DUETZ diesel
F2L511. 23 KW which I think is about 30 HP. I think theres a couple pictures in my gallery, but nothing up close.

york · February 14, 2013, 01:52:20 PM

Wick,TH did use Duetz two cyl. diesel`s because i have one in my mill-have a pic. for you hope it helps-the pins are spaced out from the pulley about 1/4 inch,so belts can slip and maybe more if you belts are deeper.....There two pins,another on bottom of motor pulley,could not get in pic. and same deal as top pin...

OK,next pic. shows how the belts should look,as for length,they need to be parallel form motor pulley to where they run over the idler pulley..

OK,hope this helps you,albert

Wick · February 14, 2013, 04:53:32 PM

Thanks. Nice barn by the way

. When you disengage yours does the tensioner pulley still contact the belts? Maybe it just needs adjustment but it didn't look like there was much adjustment left. I'll play with it tomorrow and try to put all this advice to good use. The guy I got it from told me he replaced the engine, but I didn't know it was OEM.

True North · February 20, 2013, 04:04:57 PM

We have had the same thing happen with our TH. Cant get the blade to stop, and I had no luck trying to adjust it.

Brad_S. · February 20, 2013, 04:53:38 PM

Pushing the "pins", top and bottom like the ones pictured above, usually does the trick if you are using the right size belt.
The belt will rest on the engaging pulley but not be tight on it when idle.
If the belt is still tight against the engaging pulley, you can losen the lock nut on the stainless steel connecting rod and slide the rod further out from the engaging handle.
I will get a photo of what I am talking about tonight.

True North · April 05, 2013, 08:01:25 AM

Does anyone know which belts should be used? When we got the mill it had b-90s on it, but in talking to someone else, they thought they used b-95s for drive belts. Is that right?

Wick · April 05, 2013, 06:24:07 PM

Anyone know where I can get these pins. Mine are gone and the only thing I have is a piece of bent flat iron on the top, nothing on the bottom. It could work if one was added to the bottom, but would rather have the correct part.

I will look in the manual for it

Oops..didn't highlight the qoutes. Line 1 and 3 are qoutes, 2 and 4 responses.

I have a TK but I think my pins are no where near that close to the center of the pulley and the blade stops good. It almost looks like that bracket should be flipped over putting the pin a few inches away from the pulley. steve

Dewey · April 06, 2013, 07:54:50 AM

Well sounds like you guys gave all the right info..... I have a "94" 30 Ht Its been a great mill I have been running it full time for the last 17 years !!!!!!

Steve,
A Timber Harvester and a Timber King are two very different machines. The pins on a TH should be very close to the pulley...almost touching it.

The belt you need depends on the model you have. I have the larger HT36 series and it takes a B-100, can't help you with the HT30 model. Cook's carries a similar mill and are knowledgable about TH's. There is also a mill manufacturer in PA that is run by former TH employees and our sponsor CMS employs a few ex-THers so they may be able to help too.

ladylake · April 06, 2013, 10:12:59 AM

Different machines but both have pulleys and a belt, on mine it keeps the belt away from the drive pully almost like pinching the belt a ways from the end.. Steve

york · April 08, 2013, 03:06:46 PM

OK guys,took another look at the guide pins for the drive belts and the top pin is 1/4 inch above edge of pulley and because of the angle of belts@bottom of pulley,this pin is 1/2 inch from edge of motor pulley-I always put stuff back together the way it came from Waterloo,ny...albert
