D100 (maintenance and repairs)

[bertsmobile1]

In an attempt to impress some unknowing customer is why grease fittings are installed to grease bearings that were not meant to be greased .

Any place that has metal to metal movement needs some sort of lubrication or the weaker part will wear.
Now weather having the pivot worn oval is beneficial because you get freer and greater movement of the front cross member is a good idea or not will get argued amongst tech all day & all night
I have seen mowers where the wear was so great the front cross member twisted back near 20 degrees when you turned the steering wheel before the wheels moved.
When they did the cambe r was of course all wrong and over time that destroys the king pin bush and even the fan gear .
I love hem because when the front wheels start to grind agianst the frame , drag link or muffler I get to do a $ 1000 to $ 2000 repair, nearly all labour taht the customers never complain about the price because they feel guilt about not greasing the pivot bolt
Husqvarna & JD use the exact same system, and the parts interchange
JD put a grease nipple in there & Husqvarna don't
The Husqvarnas are throw aways while the JD will run 20 years if the pivot is greased
The customers come in with a broken drag link, I put the mower up on the hoist and show them why the wheel was rubbing on the drag link which destroys the end of the link.
Then it is proper tie rod ends on the drag links , custom bush in the cross member, new pivot bolt, drill cross member for grease, replace king pin bushes and new bushes in steering shaft & fan gear .
Customer leaves with a mower that steers better than new & tell everyone I am a genius .

How do I know if I need to replace any of the components regarding the transmission drive belt?

 

[bertsmobile1]

You mark the belt ( I use a white paint pen then run it through and check for cracking , splits , torn covers or any other defects
You set the brake & remove the idlers
Hold them in your fingers and spin the pulley looking for noises or notchy running , check the pulley flange for cracks , splits or excessive wear .
Grab the fan & check it is secure
Grab the tension arm and check for excessive wear ( hole flogs out oval ) Lube with some dry spray grease .

Thank you! I will begin going through these steps this week.

I have a question, though. My D100 doesn't have any stopping ability. I lost the ability to brake a few years ago. Does this mean that I need to replace the brake pads or could there be an adjustment issue?

Depends on if the brakes are internal or external
Follow the clutch & brake pedal under the mower
On the left side the rod goes all the way down to the brake .
The end of the rod is threaded with a spring that pushes against a pin which is used to adjust the brake .
Warning here , you can not drive & brake at the same time so the brake must release before the clutch takes up the slack in the drive belt or you will become very good at changing drive belts .

Either you have a Peerless or Dana transaxle from the images in the IPL. Brake calipier is external version. One large nut can be tighten provide the pads are not too worn; otherwise, the pads will need replacing.


Brake pads are items 17.

I pulled the rear wheels to get a better look. Here's what I found. Any feedback is appreciated.

Spicer was the other one I thought of but I haven't seen in the shop yet.


Also would hurt to clean out the haystack before you have mice making a home in there.

Boy are those Rue Ring clips fun to off at times. This one is easy to get to and is not locked.

Bio, please PM me your email address and I can give you an electronic copy of the JD Technical Manual for your D100. This TM covers your tractor and not my D105 so I don't need it. It's almost 50Mb so will have to go through GoogleDrive. If you are interested...
