alternator belt

[offshorerivas]

morning
I have a jd2040 that the alternator belt can not be tighten further. it is at the end of the strap . the belt is not brand new but not a year old. the belt is from JD dealer
correct numbers on belt

Possibly wear on the pulley's over the years caused the belt to be loose? R73784 is the belt part no., right?

1st thing that needs to be established is your tractors serial number & if your tractor has a 3 or 4 cylinder engine. Then the correct part number for fan belt can be chosen. Part # T20334 which subs to R97758 is for 2040 with 3 cyl engine below serial # 349,999. Fan belt for 2040 with 3cyl engine after serial # 350,000 is R73784. PS: I sold 2040 3 cyl tractors when they were NEW.

my tractor is under the serial #3449*999 ,maybe you tell me what the lever on right side under seat is.there are slots ,i belive there are 4 dents or holes
I am still new to tractors and learning . this is our 1st tractor thanks

sorry serial 349-999

R97758 is correct fan belt for 2040 <SN 349.999 with 3 cyl engine. Lever under seat is for draft control on 3 pt hitch. D=depth,L=load,L/D=setting in between L & D IE less sensitive than L

this is offshorerivas with the 2040 loose alternator belt . the numbers on the belt are correct and go with the serial # under 349-999 what do you belive could be
the reason for the belt to be loose . It is tightened to the end of the strap .
thanks for your input

How many hours are showing on tractor speed-hour meter? Does the back of belt extend out past the belt pulley's when belt is installed? Have you checked number on belt not just on the cardboard holder?

 

[offshorerivas]

the speed-meter does not work . the number on belt is correct for this tractor .
if i am understanding what you are saying the belt does not extend past metal strap that is used to bolt alternator when tightened . now that i am explaining this, could it be that metal strap was replaced with a different size.?
