I just got in from yanking the transmission out of the legendary Bolens HDT1000 project. Some of you might know that OldBuzzard dropped his treasure off for a new paint job, a few repairs, and a little spit shine.

Yes, there will be a refurb thread going now that progress can be shown. I've got pictures out the roof but I keep running out of daylight to do it all.

I decided to take a jump and pull off the transaxle primarily because I wanted to double check the pump for runs, leaks, and errors. There was also a leak on the transaxle itself I wanted to fix. Like I thought, old gaskets, old permatex, and hydraulic oil don't mix well.

However, one of the biggest complaints I had going into this project was that it took (in OldBuzzard's illustrative words) "two men and a boy" to shift the transmission between high and low.

Now that the pump is off and the transaxle is smiling at me, I'm a little lost as to what would be the cause for hard shifting. I was hoping to see something simple like a bearing causing gears to misalign, a sheared key, or possibly something broken up on the shifting mechanism itself.

Have any one of your Bolens experts seen this and does anyone happen to know a solution? I'll tear deeper into it, I've only looked at it quickly, but I am hoping to get pointed in the right direction.

How hard should these transaxles be to shift?

Ben,

On my HT20D, I can move that lever without leaving the seat.

My HT 23 is hard to shift.
I can do it from the seat. But, it may take a few tries.
And, then I usually go in what ever range it goes into for a few feet before shifting into the range I want.
I always shift the rear end to neutral when I park it.

Something is wrong with the HDT if this is all true.

My main question was what would cause it to shift so hard?

Ben,checked with my buddy,he said if your on a pull or have pressure on the drive train it is a little sticky,but other than that shifts fine

If that tractor sat for a long time than I would guess corrosion from condensation. That being said at times one of mine can be difficult unless I rock it a little bit.

I would guess there is a problem with the shift fork or the internal ring gear cluster. It may be a good ideal to split the trans and see if a gear or bearing is bad before more problems starts.

That's on the to-do list, anyway. Dave has enough weight/pressure on it that I think a good check of the bearings, seals, and gears is in order to prevent shiny tractors from having ugly problems.

If you already got it this far apart I would reseal every bit of the rearend. Trust me Dad and I have done to many of these to know if you got to pull it apart go all the way.... As soon as you put it back in the tractor the part you did not reseal will start dripping. We just did a Eaton 12 over the weekend theres not a drop on the floor were it sits. Was there water in the oil when you drained it Ben? Maybe thats why it dont shift water down the shifter area is not good...
