Davis 102 loader

BIG1RED9 · Dec 30, 2018

I have had a MHF 202 for about a year.

The 102 loader is a project I am about to get into. I am going to rebuild the bucket and repair all the pins / bushings.

As sloppy as the arm / side rail mounts are, I want to prepare myself for destroyed bushings and oblong holes. I have looked at the parts book but I have never done this kind of repair.

For me, the part numbers did not go anywhere. Does anyone know the sizes / current part numbers of the parts required? I am using the tractor between storms and if at all possible before opening it up, I would like to learn a bit about what is required and the costs involved.

Where would be the best place to get the parts?

Thank you,
Don

Holes may be wallered into the base metal.Then it becomes EXPENCIVE as you will have to machine out the hole to true it up before rebushing.The "best" place to buy parts is where you can find them. Dealer I'd try first. However they are probably obsolete-no longer available. Then you try bearing houses,machine shops,etc.There,part numbers don't matter,they need actual size.May be best to just leave alone if only occasional use.You say you looked at a parts book.The part numbers weren't there? Wrong numbers? the dealer should have a number crossover guide.Go talk to the dealer,see what options you have.

Thanks for the input.

No parts by the numbers or through the dealer are available.

I guess it will have to wait until I can take it apart to see how it is put together. I had thought a solution would be to grind and cutout the worn parts and weld in new ones.

BIG1RED9, check your email for a message I sent you about the 102 loader parts manual.

That?s best plan of attack grind out the old welds
then drive out the old bushings have new bushings
made and then put them in true em up and weld the
new bushings in place most equipment does not
have a part number for a bushing like that because
it?s not a replacement part you will have to get the
old bushings out then take them to a machine shop
and have a new ones made it?s not something you
can?t do but you?ll need a good Grinder a torch and
a good welder

Thanks SV,

The info PTFarmer sent had links to a retailer that shows the parts available. have an email into them now. Are the bushings of the Davis loader welded in or are the bushings installed into a boss (if I have the term right) that is welded in?

I am going to step into a new world - I ordered a plasma cutter that can stick weld and have access to a mig welder. Going to begin practicing on scrap in about a week. Haven't touched the stuff since high school, but it looks like there is going to be a need so its best I learn.

The bushings are pressed into the loader arms, the old bushings will need to be taken out. If it didn't wear through the bushing, and not into the bore where the bushing goes you simply put the new bushings in then you probably have to ream the inside of the new bushing for the pin to fit. If it wore through the bushing, and into the loader arm itself the hole in the loader arm will have to be made round again then a insert would need to be made, and pressed in the loader arm to accept the new bushing, or you could have new bushings custom made.

Here is a front axle support where I bored the pivot hole oversize, and made a insert to accept a new MF bushing.
Boring oversize.

New insert installed to accept new MF bushing.

Thanks PT
Is the portion of the loader arm where the bushing resides a "tube" which is welded in or is it machined / cast into the arm like the front support in your picture?

It could be done either way, made into a steel casting then welded to the arm, or simply a tube welded into the loader arm. Chances are on the older loaders like the 102 it is a steel casting welded to the loader arm.

I was able to track down MF factory parts for the loader.

Have it apart and the good news is the bushing didn't wear through and into the arms, however the slop is being caused by the frame dog ears that the bolt goes though. Also, this is some tough metal as the old bushings and bolts had little wear. That was the case at the bucket too.

I am putting in the new bushings and bolts and will plan to deal with the frame issue in spring.

My thoughts are to drill out the dog ears with a step drill to the same size as the arm hole (1.375") and then cut down the old bushings and use them as inserts.

Open to any other ideas.
