310-8 Won't Shift into Low gear

[Erik1979 11]

Good Morning!

 

I recently acquired a 310-8 Wheel Horse tractor with a tiller attachment to till some fields in the back yard.  This setup was working great until last weekend when the Tractor shifted itself into High gear and wouldn't shift out. 

I generally do a lot of reading and research before posting anything in forums. I've managed to remove the Unidrive 8 speed Transmission and I've discovered the usual culprit High/low fork is completely broken. 

I'm not completely sure where I could pickup a replacement.

 

The Serial number (ID Number) listed under the Seat is 2110K806          35097

I'm hoping some of you guru's can help to point me in the right direction.

 

I am having issues removing the input shaft and would also like some advice for that process, as all the videos I've found online for this seem to jump past the process of removing this and I won't want to damage anything. 

 

Thank you all in advance, 

 

Erik

Guessing you mean removing the pulley? 

If so make sure the set screw is out completely and get some penetrant oil on it. 

A small puller works if you can get behind it. other wise a couple of wooden wedges behind it. 

Most likely shift fork but who knows untill the case is split.

Here is a list of the parts and the shift fork shows as no longer available. There are two pages making up the transmission parts.

This site has a couple vendors that might be able to help you out with parts. You could also place an ad in our wanted classified.

 

Never know who's got what laying around. I may even have that shift fork for you.

[Erik1979 11]

Thank you all.

I may have gotten lucky and ordered the last one available from a-ztractor.com

 

I've got the case split. The Differential is out.

The oil was nice and brown, and I've definitely got some cleaning up to do to remove some rust.

I've been spending some time this morning watching some rebuild videos on YouTube and reading through the Transmission Manual.

I'm glad I did. I had no idea that the shifting forks were held in by ball bearings. 

 

I'll make a point to take some photos when I get home and back to work on it to post here.

Keep asking questions.  

 

You'll be fine.

Here are my videos if you have not seen them.  The 1st is an 8 speed with the 8 pinion differential.  The 2nd is an 8 speed with the 10 pinion differential.  The hi/low mechanism is the same in both transmissions.

I've managed to get most of the Tranny apart. 

Does anyone have any suggestions on how to remove the plug holding the ball bearings/spring in place?

 

I'm attaching photos (as promised) of where I'm at and the interns who are helping me out on the project.

Buff Orpington?

Is it a solid steel plug like a baby miniature freeze plug? You might be able to drill it very carefully, then stick a screw in it. Then pull the screw with pliers.

[Erik1979 11]

Thanks Eric.

 

Yes, I got a flock of 20 Buff Orpington's this year. They've been great to have around the home. Not too good at turning wrenches, but they're trying!

 

I was thinking I may have to drill it out, but I wanted to make sure there wasn't an easier method.

What should I replace this with when I'm re-assembling this? Gasket sealant? Silicone?

5 years ago we got a dozen Buff Orpington chicks. 

Some went to neighbors. 

We still have 8 hens. Still getting eggs too.

Silicone will work just fine to reseal.  

 

 

When disassembling...

 

BE VERY AWARE of where those   balls go. 

They are considered mythical in the ability to disappear under the absolute heaviest bench.

Eric is correct...drill just enough to get through it.  It is a 1/4" hole, try a 1/8" drill 1st.  When you finish the trans, plug it with a bit of silicone grease will work also.  That sits up against the trans mounting plate, it does not leak if you do not plug it.  

[Erik1979 11]

Awesome, Thanks for all the support.

 

I'm not sure what this forum's policy is on recommending retailers, but I would in no way recommend small engines pro dealer. I placed an order a week ago for gaskets and seals for this project. I called today to get a status update and found they didn't actually have the parts. I cancelled the order and ordered from ebay. 

 

I'll do my best to keep those ball bearings once I get them out.

have the parts

 

For future reference,  we have a few very good vendors signed up with this site. 

 

You found A to Z Tractor in PA already. 

 

K & B Horse Parts is excellent.  

 

Wheelhorsepartsandmore would likely have all the gaskets you'd need for that transmission.  

 

Whatever you need.... just ask.
