Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
Greetings, My name isXXXXX and I am here to help the best I can. My goal is 100% satisfaction. Let's get started.
Can you provide for me the bolens riding mower model number... Also, abut how old is it?
If this is an older unit, I have access to such diagrams, but it may take a bit of time to locate.
If it is a newer unit (since MTD bought the defunct Bolens and Troy-bilt names), then those diagrams are also available, but I would still need the model number, not of the engine, but of the rider itself
If it is one of the newer MTD units, I also have this to offer:
It would not actually be 100% inaccurate to call this a "Design flaw".
Bolens WAS a quality brand of equipment before MTD bought them out
and MTD, to their credit, continued that great quality for about 5 years.
But that has been 20+ years.
Bolens, Troy-bilt, Yardman, Yard-power, White Outdoor, are all Formerly quality brand names that were not able to compete with the cheap mowers made by Murray, AMF, Roper, and MTD
So all of those brands went out of business
So then the NAMES Bolens, Troy-bilt, Yardman, Yard-power, White Outdoor, and of course Cub Cadet were purchased by MTD
MTD is now putting those Names on their cheaply made equipment
The public is being deceived into thinking they are buying quality merchandise just because of the name
You can read more of this on Wikipedia http://en.wikipedia.org/wiki/Cub_Cadet
So back to the problem at hand
The Problem is poorly designed equipment overall made of average quality materials
the belt guards will slip
the angles of the belt path are sharper than they should be
The mower will work better if adjusted to a Higher cutting height
ALSO, you cannot WASH this unit at all with water
The bearings are sealed against dirt, but they are not sealed against water
so the water will actually be sucked into the bearings (especially if warm) and mix with the grease
this will cause the bearings to wear much prematurely
If the bearings in the pulleys fail at all, then the pulley will slip against the belt and cause belt wear but also will throw the belt off if it freezes when it heats up
So check all the pulleys to make sure that they spin without ANY noise at all or vibrations
A good bearing in a pulley will spin smoothly and make no noise and you will not even feel it spin much
If the belt ever comes off, you cannot reuse it
it must be replaced on one of these
The back of the belt usually gets damaged and it will not stay on afterwards
The deck design is not good
the way it is hung combined with the subpar quality in the materials make it susceptible to warping or bending in the middle
if the deck bends, then the pulleys will never line up perfectly
You cannot bend the deck back because it will weaken the deck further and it will bend even more easily
Also, the materials and design around the spindles on the deck is not good and if you hit anything with a blade, the deck will bend and the spindle will now set at an angle
This misalignment of the pulleys will again cause belts to jump
Look hard at the belt path. The belt cannot twist then twist back and stay on
The belt or a pulley cannot touch anything at all period
Look for a spring that may have come off or has weakened
and may not be applying enough tension
The information included in the cub cadet article is a mirror of what happened to bolens, other than MTD Never made any quality Bolens equipment. The ONLY bolens equipment MTD made was just simply taking other already existing equipment and slapping bolens on the MTD cheap tractors.
If your equipment is pre 2001, then your equipment was not made by MTD, so you can ignore sume of the above, but
the reasons for the belt jumping off, pulleys going bad, etc are the same and shoud be looked at
We just have a lot more trouble with the MTD Bolens equipment then we ever did the pre MTD Bolens in the scores of years previous
the model you gave is an MTD bolens piece
don't know how old
The engine serial number will tell us the age of the rider,
Which belt is it, there are usually three?
here is a treasure trove of info for you.. It is all the manuals published for your unit
but before I can research further, I need to know which belt
engine #6bsxs5012vp 276470
The numbers I am looking for will be on the engine shroud or on the valve cover
they will be like model 28K2802 Type 1123-E1 Spec 04245455455 and will usually be stamped into the sheet metal
and labled as above or close
The drive belt is a tricky belt to work with on the 700 series MTD units
I think I have a complete service manual that will help solve your problems with full color photos
is yours a hydro or the variable belt slipping design
ALSO, I fully expect your problem to be a missing or broken tension spring or idler spring
these springs are a weak point on these designs
051114ze03076 only numbers i could find
dang... Wish you had the hydro.. Much better design
getting service manual
my friend put it on he took the tension spring off for some reason and could'nt remember where he took it off , so he might have it hooked up wrong
Great.. That is expected
I am having some difficult
why do you not look at the parts list in the group I sent
and see if it makes any sense
I will continue to look for the service manual location
it is burried on the MTD education web site and not readily available ro the public
but it will be to you
This may be the wrong diagram
If so, I will find you the right one
I will convert the question to Q&A mode rather than chat
we wil be notified of each others replies via email so we do not have to be waiting on each other if this is OK
You can even ask follow ups even after you accept..
is the service manual I was looking for for the 700 series
