Tru-Turf drive gear shaft repair

Our Tru - Turf roller drive gear has a lot of movement . Ordered the necessary parts for repair . Parts took months to come in . I'm glad it didn't start leaking . Laying up a roller during mid season wouldn't be a good thing . 

 Here is my home made drain extender .

Disconnected the drive coupler from engine 

Remove the shock linkage on both sides and double link chain . . 

Loosen off all 4 lines at pump 

remove bolt for pedal linkage and 4 base nuts on pump ( studs are welded in on underside).  . 

Lift up a carefully pull out making sure not to damage any steel lines ,.

Clean up in parts washer bin .

Fit pretty good in my large drain pan ...trying to avoid spilling oil everywhere. Remove both chain tensioners 

Remove drive gear bolt and and  key most likely will have to be replaced . There is a lot of torquing back and forth .  

Next I removed the 4 bolts that hold the bracket in place .

Tensioner bracket. 

To split the pump there are 2 torx head screws that have to be removed 

  Pull pump apart by hand . There is a rubber seal between the halves . There are 4 large pump balls that you want to keep in place .

 I wrapped a rag around them and covered it to keep it clean . 

 Now we are at the problem part .

New parts . After waiting many months the wrong shaft was delivered ( single gear ) ? How does this happen when you order from an OEM # I'll have to make it work ...Not having a roller in the spring is not an option . Most of it is keyed on the first section . Dealer was contacted about the problem for records . 

Remove the cir-clip holding the shaft in place 

Pushed the shaft and bearing out with the press .Could easily be tapped out with a hammer 

Remove the old seal 

New seal sits flush in bottom . Using a socket this way works great 

New seal in place .

 Pressed in the new bearing . and pushed new shaft in and installed cir-clip.

Installed gear and new key . Notice that it was a little short . 

Shimmed up the gap and installed a longer bolt .

Assemble both halves and re-install torx screw  to hold pump halves together . Reassemble I reverse order . Change Hydraulic filter and new fluid . 

I was amazed on how much wear took place . Old bearing wasn't seized and in good condition . seal was also in good shape .


  1. Hi Bob. How did you go about sourcing the output shaft? All of my eaton dealers are telling me the pump is made to be junked. No replacement parts are available. If you have the part number still it would be much appreciated!

  2. Dealer out sourced I'm assuming. Part # was EATON24737-000. But it was for a single gear drive. The # should be close enough for them to find you the double chain drive length
