Can not argue with an answer that specific, pressure drop with middle cylinder having good pressure is exactly what I have. I will start a new forum for the rebuild AFTER I tear the head off, inspect pistons and sleeves etc etc, and report back here of course with a few mandatory pictures...

Will do Wolfman my wsm mentioned the spool also and said turn To the “o” mark which I couldn’t find no matter how much I de greased and wiped . Should I start a new forum for the pending rebuild or continue here what’s proper etiquette lol

So after testing I tried to rip into the FEL to detach it went great but got stuck MANUAL says to disconnect the 3 hoses with quick couplers Next step is where I’m stuck After hoses are disconnected then “reconnect the hose remaining on the front hydraulic block to the out port of the front...

Finally pulled the rocker cover off and rocker arms all have slight play as described I turned motor by hand with glow plugs out. Re compression tested with full battery charge and charger on for test. Compression did go up but still have two cylinders low 275 rear 375 middle 265 front Soap...

W I will not wet test thank you all for the warning I had the oil can squirt bides in mind personally. for the repeat compression test 1. Bat charger hooked up for testing 2. Leak check after tests with soap spray Anything else before re test guys?

solid advice thank you Do I tap starter to cycle pistons up and down to inspect or can I turn with breaker bar somehow like gas engine?

I will look into a wet test soon and report back after other things discussed. I’ve got a FSM so will read up on wet test procedure is there any chance I can get away with a top end rebuild or am I looking at a full rebuild also does rebuild involve removing the FEL?? Fun stuff Flintknapper...

Will do wolfman will re test pressure first or take off valve cover and check rockers for a little movement FIRST?

How do I ensure adapter isn’t leaking I did pause for several seconds after each test to see if pressure bled off afterwards just trying to be sure. I will follow your advice with the head first then block. Is a “replacement motor” an option? Direct fit bolt in?

Flintknapper “It wouldn't hurt to check it again, Be sure all glow plugs are removed Having a fully charged battery hook up my battery charger to the battery at the same time.... Might as well do a 'wet' test too....while he is at it.” I will wait to see if any other recommendations come in and...

THANK YOU TO EVERYONE!!! d2cat “I'd suggest double checking A very small variation in procedure makes a difference in the readings.” What variation would you recommend and I’ll do them? I performed test from glow plug holes with all plugs removed. I performed the test twice front to back with...

Ugh indeed. My heart and gut said exactly that thanks as always wolfman and flintknapper thanks also . ok so I’ve pulled a Jeep 5 speed transmission and replaced it’s clutch and bearings etc is this a doable project for me getting it rebuilt accept for the machine shop of course? can anyone...

Thanks to everyone as always for your time and help ! So questions of the day are: Is this range of compression acceptable (265 psi low 350 psi high) or are my young un educated concerns reasonable in this case? what are my best and worst case scenarios? with these numbers in mind what is my...

“That sounds right. Just match the length to the glow plug.” Ok bought the tester and spent a day getting it cleaned and torn apart. Wolfman, On length, the kit had two glow plug adapters right width and thread but both were too short.. PIC ATTACHED Both yielded the same pressure results on...

Does M10 x 1.25 sound correct for my l2250dt glow plug size? Info from Steiner tractors That size is included in the kit I attached pic of. Thank you again to EVERYONE

Finally getting the money after the holidays to invest into a compression test kit for Diesel engines and what may come afterwards. I need this tractor to work so I will keep updating. What size is the glow plug for my kubota 3 cylinder I posted a kit I’m looking at with sizes it has

“Coolant level and operating temps OK?“ Yes coolant level topped off during initial service and op temp stayed just below mid range entire time no fluctuations. Antifreeze did look dirty but engine oil was not milkshake like

“Do a compression test” I will search here on the forum and YouTube for how to. Is test done from glow plug or injector port or ?? sorry for delays in responding we are off grid 4500’ elevation satellite internet only no cell phones THANK YOU TO EVERYONE FOR YOUR TIME

That “good days work” consisted of clearing a brushy rocky half acre of our property using loader a lot to dig out and move rocks pushing brush out at the root and piling said rocks and fire piles all while box scraper grading. About 3.5 hrs consistent work Finally stopped once I noticed the...

Update Changed engine oil and filter Ran for a good day of work and it seems the blow by is getting worse not better. Both at idle and throttled up feels like power is good and runs and starts nicely but that blow by vapor or smoke is really worrying me. this is thickest I’ve seen snapped a...
