Jinma 254 slow turnover

[SPIKER]

I say that we need a bit more info:

VOLTAGE AT THE STATER & at the BATTERY and across the starter sol when cranking.

should be 13.4 volts at the starter across the battery terminals. if it is not then there is a loose connection or a battery prob. I killed my battery last weekend 2 weeks back now I left key on for a week and now have a 12 volt battery with a full as it can take charge not good enough (it still starts her now as in warm temps but the alt is outputting a steady 25 amps and that is not good for it. I KNOW I have a hydrameter someplace to see if the cell is simply weak acid or what and I'll see if I can find soem of the X14 stuff (forget what it is but it cleans the plates off the battery when they carrode up.) also I say clean all connections frame to battery wire is a good spot as well as battery+ to starter and battery terms...

Voltage at the starter solenoid is 12.5 .When the starter is energized the voltage drops to about 9.
Put a floor jack under the fel to lift it up so I could tow for a jump start.I will try to jump it tomorrow.
I had the starter looked at by a starter -alternator rebuilder and He said its OK,although an auto parts store said it was bad .How you figga?I tried to get a strap wrench around the crank pully to turn it over by hand,it was too hard to turn but I didn't have a very good grip .
You guys are great

Problem could be battery, Sometimes they will give 12 volts but drop quick under a load. You could charge the battery then take it to auto parts for load test on a meter. Did the voltage return to 12.5 or close once you let off on the starter switch? If not my vote goes for a new battery (fun to spend other's money).

Open the compression release first

I pulled it with the truck to jump start it and the tires just spun.
Highest gear, medium gear ,compression lever on and off ,4x4 on and off.Seems like something is binding in the engine.

Well, it was worth a try. Most of us were trying to help you eliminate all possible problem sources external to the engine, in hopes you could fix it without a teardown.

Well,,seems to me,,before I would replace engine,[or tear it apart,or take hydro pump off,,like you said you did,I think],,would put new battery,,new starter/silanoild,,,new cables,,and new anything else that may be in your starting system,,,,,,,just appears to me that there must be more to the story than you are letting us know,,,,,I mean,,most people[all but you],,would never assume motor was $%@#!@ up,,if engine wouldn,t turn over fast enough to start it?????unless,,,there was more to story,,,maybe you are a deisal engine expert??,,,who knows??? You could be,,,,,,,,thingy

<font color="blue"> I have a Jinma 254 and it won't start .Ran fine for 100 hours.
It cranks over very slowly ,battery ,connections and starter are all good .
It seems something is binding in the engine. </font>

Hey Ray,

I know that this is elementary, but have we checked that the Radiator has water? Or that the Engine was not run low on Oil?

Just trying to leave no stone unturned.

I hope that you don't have engine damage.

I am a contractor and my crew was running the Jinma moving gravel.It has a slow oil leak and the crew said that they topped it off .The oil is clean as a whistle .The radiator is full .I took off the hydraulic pump .I put in a new battery,Had the starter checked by a rebuilder.It doesnt want to turn over at all by push start.What else is there???Stymied!!
