2394 (HELP)!!

We are working on a 2394 and have rebuilt the powershift. Shifting going straight the power shift works great. If you come to a point where you have to turn abruptly it goes crazy for a second. C1 and C2 pressures drop and C3 and C4 spikes. It has normal bypass from the steering going to lube and removed the valve stacks to check for blown gasket and are ok there as well. We belive this is what may have took out the powershift in the first place. Have any old case guys run into this at your dealers back in the day?

Sorry, but I have never ran into a problem like that before. If C3 and C4 spike, I assume you mean jump up in pressure, Are you getting a momentary trans lock-up? Tells us what the tractor does and if it always will have the same symptoms during a hard turn. When making a hard turn does the cylinder have to reach the end of its stroke before things start going wrong? Rod.

Zack, Sitting here thiinking about the problem and wondering why the interaction between steering and clutch applicatin changes! On previous models lube pressure (steering return) controlled the reverse lockout spool which had lands on it to direct oil flow. My first thought is hydraulic as steering affects it and there is no electrical connection there.
If I were you I would check steering return at hard lock or quick applications of steering wheel to see if the steering return is constant.

If you have a flometer insert it right into the steering return and watch it as you steer. Be sure the trans is up to temp when making this test as cold oil can mask pump problems.

Many times on the old systems we would run into instances where the tractors would quit moving on a hard turn and resume when the steering was released with a marginal steering pump.

Keep us posted

Thanks Mel. We have done some more testing on it with the flow meter and found that the steering pump is misleading at times. It barely has 3 GPM at 2000 RPM. We have another one on order and are going to try it out. Everything else is checking out. Have had everyting triple checked now otherwise. Ill let you know how that goes.

Only suggestion I would have is might ask some one familiar with the electric controls if hooking the analyzer up, that Case made all dealers purchase to see if that would diagnose anything. I ran a couple of tests about 20 plus years ago and it got me down to the problem for me. However, it was not the problem you are having.

I can only dream of owning a 2394 and I am not an expert on the 94 series.

If this were a 70 series I would say it sounds like a cab mount failure causing a linkage problem.

A problem that would cause the clutches to engage the way you are describing in my opinion would cause a power-shift failure.

So it may be wise not to drive it until the problem is figured out.

IT IS NOT A 70 series. DO NOT run it and destroy it.The shifting is all controlled with electronics, not mechanical controls. Listen to a qualfiied tech such as Mel, Rod, or Thad, that are still turning wrenches to give you advice. I am seeing a lot of advise from people who don"t even know what controls these RPS34 trannies. Mel and I discussed this just last night on the phone. there was an earlier post about 870 shifting/ hyd problems, and a poster stated that perhaps the dipstick was broken off! 70 series have sight glasses rather than dipsticks, unless you are talking aboit 12-15s which also went through a tranny oil level/dipstick change.
Not trying to BELITTLE anyone here, BUT don"t offer advise that could cause someone thousands of dollars, due to poor uneducated advise. If you know nothing about a series of Case tractors, don"t tell the user to just run it!! I have been away from wrenching these tractors for way too long, to offer tech advise, Zack, rely on info from Mel, Rod, and Thad.

Today's Featured Article - Restoration Story: 1964 JD 2010 Dsl - Part 2 - by Jim Nielsen. Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal. As a resul ... [Read Article]
