    If his MX135 is anywhere near as bad as mine was — not good to ignore it. All that chatter has to be hard on the components. And the cure is easy. Yes, as mentioned, Mobil Delvac Tractor Hydraulic Fluid, formerly known as Mobil 424. I think there are a few other offerings out there that would work as well, just make sure it is a premium hydraulic fluid.
  2. In the tractors the mechanical pump 5.9s ran until at least 2001. There were 6.7s with mechanical pumps after that yet. $4500 sounds kind of high for a 40 year old 5.9. Those “junk” engines you speak of generally run from 15-25,000 hours before overhaul. I have yet to see an IH engine (as much as I like IH engines) do that. Not even close. And the Cummins is perfectly rebuildable. Just isn’t quite as easy.

    If you have a Maxxum 115, that is not a legacy CIH product and apparently doesn’t have the chatter problem that the legacy CIH products can have. I would not put additive in it.

    The MX135 shares most parts with the MX100/110/120. I do know the MFD axle is a size larger than the smaller models. Also the injection pump has the aneroid that the smaller models do not. Could be the cooling system is a bit larger, I can’t remember exactly. What you are hearing with clutch engagement is most likely clutch chatter. You are probably having brake chatter as well when you apply the service brakes. I had that problem bad with my MX135 for over 1000 hrs. Tried CNH’s magic juice axle additive to no avail. Finally got rid of the Hy-Tran and went to Mobil Tractor Hydraulic Fluid and the clutch and brake chatter was gone in about 2 hours of operation. The chatter is a result of prolonged use of Hy-Tran Ultra and/or Ultraction. This problem can afflict the 5100, 5200, MX Maxxums, MXC, 7100, 7200, 8900 and MX Magnums.
  5. Thanks! I have not used these before. Does anybody know if Sturdi Sleeve is as good as Speedi/Redi Sleeve? Sturdi Sleeve looks the same and is more reasonably price for what it is.
  6. What are the bearing numbers? I just ordered NTN rear axle bearings for an MX150 from my preferred bearing supplier. He said Timken has had big supply problems.
  7. MX150 has been leaking oil from the rear axles, needs new seals. The axle itself is too grooved to seal properly, needs sleeves. Axle sealing surface is 130MM, housing is 160MM. Flange axle just to make everything lots of fun. Is there a specific seal and sleeve that works for this tractor or do I just piece it together? Supposedly a 99491 sleeve will work for this and I assume the original 130x160x12 seal gets used with the sleeve. Any insight would be helpful! Thanks!
  8. Different type of injection systems, different kinds of problems. VP44 - electronically controlled mechanical distributor pump; more pump problems, injectors are usually pretty reliable. CP3 - high pressure common rail system; more reliable pump as far as I know, injectors tend to be more problematic and they are expensive. More $$ to replace pump and injectors with the CP3 I’m pretty sure.
  9. Lovely. That does smack of a lack of lubrication. Who did the pumps come from if you care to say? I got my mine from Blue Chip. Mid level rebuild.
  10. Parts shown with the end mill are components I made to rebore and sleeve a destroyed oil supply manifold bore for an MFD clutch.
  11. Yes. Clapped out 16x40 Summit and a decent Toolmaster. Got the lathe a year ago and the mill 4 months ago.
  12. I’d fire up the lathe and mill and make a new one but that’s just me.
  13. Do you know what was failing? Was it the pumping components or the controller? I just did the VP44 in my pickup this year, 200K on an original, I’m pretty sure the mechanicals were fine, pump computer failed.
  14. You can tell a deleted truck while running past it. Just have to know where to look and for what.
