Sticking Brakes So here's the update. I finally received and installed the valve plate kit. I refilled with Super UDT, and my first test drive max speed was exactly... 10mph. I didn't fix a dang thing. Armed with a little more knowledge, thanks to AdamsRepair, I decided to investigate...

We'll done! This is just another example of how different each machine is setup; my hole spacing was 2.25" from the outer hole to my new extended mounting point. I wonder if our HST levers move the same amount? The movement should really be described in degrees that the shaft rotates, but...

I will definitely be investingating the brakes... after I get the trans put back together. Ha! I bought this unit used. It was leased to a chemical plant, so it drove around in some corrosive stuff. The pressure relief knob and posititive traction cables are seized, so I would not doubt that...

I thoroughly enjoyed the pics in your album. Looks like you definitely know your stuff. I should just put a bunch of stamps on my RTV and mail it to you.

Thanks so much! No doubt, you are the right person to ask about these things. I was lucky and had ordered that kit. I will explore having the cylinders blocks lapped. You bring up a great point... although it has not been in the mud much, it does seem to have some corrosion issues. I wonder...

Jumping back a few posts, I thought I'd share my lessons learned from DIY relieve pressure checking. If you are not comfortable with high pressure hydraulics, do not attempt this. Every component in the test line must be rated above the expected pressure. A hydraulic pinhole leak is not...

To clarify my previous post, although for a forklift, I found this video helpful in explaining the concepts behind our variable swashplate hydrostatic transmission. The first 40 seconds are kinda silly. Our HST lever is analogous to the black lever in this video. The video shows one variable...

TRIBUTE100: These are the same settings that I found on my RTV when I purchased it. When depressing the foot pedal, the HST lever started moving well before the throttle/governor moves. This is due to the excessive slack at the governor cable, yolk end. This bothers me because the HST lever...

Thanks. I found that page shortly after my first post... oops. I do not feel any defects with my fingernails, but that's a very subjective measurement. I zoomed in on the WSM image of the cylinder block in my electronic WSM. The surface appears to be very smooth, and it's described as...

Later this weekend, I will post my recent experience with DIY relief pressure checking and adjusting. I have some good photos, but my camera is not with me right now.

The only mention of idle speed in my Work Shop Manual is during the procedure for "Checking Neutral" or creep. It states 1350 rpm. The rated engine speed of 3200 rpm appears many times throughout the RTV900 manual, especially during the Traveling Speed test. I found it strange that my machine...

Hope I don't muddy the water with this crazy post, but just like TRIBUTE100 experienced, my machine would reach the WOT stop well before the HST lever achieved full motion. My machine shifts like a dream and has zero creep, so I didn't want to mess with the neutral adjustment or servo settings...

TRIBUTE100: This sounds very promising for eeking out a little more performance on a non-warranty machine. FYI, when on jackstands, I think the wheel speed is double if you don't have the diff locked. Someone "tampered" with a 2009 RTV900 that I've driven. The tamper wire wass gone and the...

Hi all. I recently bought a used RTV and have been trying to resolve an issue. Any advice would be appreciated. Problem: 2007 RTV900 with 1137 hrs only achieves 10 mph top speed in high range on flat/level road. I measured this with a GPS. Medium range also yields 9 mph. It is also very...

SpudHauler: I can't find a dyno curve for my exact D902-ES03 engine model, but this link shows the D902-E3B engine series gains another 3.2hp if it's properly setup for 3600 rpm. http://www.kubotaengine.com/products/engines/kubota-engine-line-up However, if you click on the brochure for those...

TRIBUTE100: I've been struggling with the same issue on my 2007 RTV900. The servo lever was 1/4" shy of full movement. It was being limited by the wide open throttle (WOT) stop screw. As a quick work around, I wanted to increase WOT, but was uncertain where these engines redline. Thanks...

I recently benefitted from the excellent instructions provided in this thread. Surprisingly I had a little trouble getting the correct boot kit from my local dealer. Thought I'd share my lesson learned for others. I only needed the outer boot kit. They provided me the inner boot kit and were...
