46gt deck question

[mmeyer]

hi all!
i have installed the 46GT deck under my 682 - i had no idea what belt to use from the motor to the deck, so i measured and used a Gates B99 belt. it worked, and mowed fantastic, but the belt is coming apart - i dont think this belt likes the compound bends it has to make. my question is what belt should i be using? thanks all!!!

Those Gates black belts are not meant for twisting and turning, as you've just discovered. Go to your local CC dealer and get a 954-3042 belt. That is the belt you should be using: the OEM belt.

thanks a bunch matt! i had a couple original belts laying around, but those are for the 44c and 50c decks, and this 46gt belt is much longer - problem i had was i do not know what tractor numbers that this deck came with originally - that made it impossible to find the right belt at the cub cadet dealer here.

so that part number belt will work great on a 682 with kohler KT17 and 46GT deck?

what tractors did this 46GT deck come from?

thanks!! you guys are great help!

 

[mgonitzke]

That belt will work on any 82 series through early Cyclops, except the SGTs. I think the deck was introduced in the late 80's with the 1811 and such, but they were pretty common on the 'cyclops' tractors. I have one on my 782D that originally came from a 1541.

cool - i will order that belt tonight.

interesting info i found on the cub cadet parts page - i found that there are 2 different 46GT decks, look similar, but they show a different belt number for each of them - one deck is listed as 321 , and the other is 336 - the belts they show for these are 754-3048 for the 321 deck, and 754-3043 for the 336 deck. of course the descriptions do not tell enough info to know if they are the same belt (or real close to it) but i thought it was interesting that neither number matches the belt number you gave me. is the number you have just a newer cross-reference number in the cub cadet part system?

nothin like a good parts hunt!!

also, on fitting the deck to the mower, i found that i had to use the forward set of holes for where the long hanger arms are bolted the the very front mule drive (the pivot bolts) - if i did not do that, that main drive pulley on the deck would touch the brake shaft under the tractor

 

[mmeyer]

Matt - does your deck have part number 336190 on the tag?

 

[mgonitzke]

Not sure...it's 1300 miles away from me at the moment...

ok, i think i have this figured out now (looking at the cub cadet parts system again) - i just wanna write this somewhere in case someone else runs into the same thing - the 46GT deck model number i have is 336 in the cub cadet parts system. they do not show a belt for this in the mule drive part listing - however, they do reference the 333 mower adapter kit - so i looked up the mower adapter kit, and sure enough, they list the mule drive belt in that picture. that part number is: 754-3042B

so the only question i will have for the cub cadet parts guys will be this: is the 754-3042B belt that the parts system list online the same as the 954-3042 belt that Matt was kind enough to list on here (i bet it is) i will post that info later today hopefully so we have a definite full answer!

btw, Matt - awesome website you have!!

 

[mmeyer]

confirmed! looked up the 754-3042B number in the parts ordering system, and that number is superceded by the 954-3042B.

so anyone putting a 46GT deck (336) onto a 82 series tractor (except supers) needs to use the belt 954-3042B. just like Matt said. (not that i didnt believe him, just wanted proof through the CC parts system of where he got that number)

hope all this hunting helps someone else someday!

thanks again Matt!

 

[mgonitzke]

Yep, a lot of the numbers that start with 7 now start with 9. My dealer told me CCC likes to change part numbers a lot...

 

[mmeyer]

ok, bummed now - got the belt - put it on - its about an 1" to 2" too long.... grrrr... now what? hopefully i can find one slightly shorter...

Michael, is it possible that because you had to mount the deck further forward than you anticipated, the correct(?) belt is now too long ?? I had not noticed any comments from Matt or others on whether the deck is actually properly set up. <font size="-2">(Just some dumb observations. A.)</font>

 

[mmeyer]

allen, that was the first thing i thought of too - but the installation manual for the mule drive/deck shows that it should be installed into that farther forward holes in the mule drive just like i have mine set up - i printed that document out last night and went over every connection/bolt to make sure they are all in the right place, and they are.

thats why im not sure what to do next - i have been trying to find a slightly shorter belt in the cub cadet parts system, but have not had much luck yet

 

[mgonitzke]

If you look at my picture, notice the carriage is back one set of holes on the mule drive.

 

[mmeyer]

maybe i could raise the engine up 1" ? or would that throw off the drive shaft angle too much?

 

[mmeyer]

if i put mine back one set of holes, my deck pulley grinds itself to death on the brake rocker shaft that hangs down just below the tractor frame

 

[mgonitzke]

Are you sure you have all of the right parts? Mine works fine in that set of holes. I wonder if the pulley on your deck is meant for the later cyclops tractors that had bigger PTO clutch pulleys and therefore a larger driven pulley on the deck, too. A pic would be really helpful.

 

[mmeyer]

good idea - i will post some pictures tonight yet of the whole setup!

wouldn't smaller deck pulley make this belt be even more loose?

i wonder if there is a shorter double pulley stack - that might help?

Michael, if all else fails, phone or e-mail Charlie at C C S, he probabily knows off the top of his head what the next smaller belt is.
