Hi Guys, This is not about my 4500DT this time but same principal. I have a 1997 Mitsubishi Canter 6 tonne tipper and I have replaced the pinion and carrier bearings in the diff. I needed to add a 2 thou shim on the pinion because the preload was too tight (these have a non crush sleeve type...

I have a M4500DT. I have been replacing rings etc in the engine, so I havent put the front on yet. Radiator not on yet or power steering etc. Its just the block on the tractor. I decided to compression test it before complete assembly. Also I have connected the injector pump and lines to the...

Before I bought my tractor an M4500DT someone must have run it in to a tree or something, they replaced the radiator and hammered out the front bonnet panel, but there is no front panel radiator grill with the lights etc. There is a wrecker with fair quality parts off a M4500 which says "low...

I live in Australia and I got sent the wrong three orings for the gear case cover for the M4500DT. These are the ones that feed from the oil pump and back through the block to lubricate crank and cam. The gear case has circular channels cut out to fit the orings in. The first ones sent were...

I have replaced worn piston rings and rod bearings in s2600 engine Kubota M4500DT. No knowledge of the previous life of the tractor but when I got it the oil hadn't been changed for a long time. I read if under the crown is black then it would have been overheated. Photo under crown is a lacquer...

I have the engine stripped, pistons out, cam shaft out but the mains are left in because the engine is still on the tractor and it is staying there. I don’t want to go as far as remove the block. I am hoping the mains are okay, the rod bearings have some wear and some contaminant scoring, they...

My wrist pins on M4500DT S2600 engine have some have some play at the end when in the rod bushes. They measure within ½ wear allowances of what the manual says which I think is a bit much .15mm .0059” is the specs attached diagram allowance. There is some slight wiggle at the end of the pins in...

I have a supertight pully bolt that wont free up. Front end is off and engine is on tractor fully supported. I have put it in high gear, handbrake on, a chain around the pulley to take some of the turning force, with rubber under to protect where the fan belt rides. I have hit down the washer...

Has anyone had experience with bearing replacements on these tractor engines. I have taken out the pistons, no scuffing and within spec, but I need to replace worn rings. Bores are within spec. The rod journals mic up fine but the bearings are worn so need replacing. The main bearings cant be...

I see on some you tubes, the test for play or failure in a rod bearing, is to tap on the piston with a mallet and screwdriver on the down stroke after TDC. There is supposed to be some slight downward movement, or at least not a solid metal sound if the bearing is bad. I am skeptical if this is...

Is it not possible to drop the sump on a M4500DT to inspect the bottom end bearings, without removing the entire engine from the tractor?

Further my previous thread: low compression and leakage past rings on one cylinder Cylinder 6 bad leakdown test results, worn/broken rings in that cylinder, with carbon build up and blow-by. Tractor not worth reconditioning so I have decided to keep running until it gives up. Question: is it...

Okay guys, Sorry for the long thread but I am trying to be thorough. Here are my engine (S2600-A) tests done. Re: previous thread, post injector ignition knock on M4500DT. Engine starts easy doesn’t run rough, has blow-by, if I remove dipstick some bubbling of oil. Only blows a bit of smoke...

I have noticed a knock in the engine on my M4500DT. This is my first tractor which I havent had for long and not used to its sounds. I have a small diesel tipper and Kubota excavator which are quieter but have the usual diesel tappet sound. The tractor has a noisy valve train sound which I...

Hello all, I have just bought a Kubota M4500DT. I have browsed this forum and found some answers, thank you all. Special thanks to JohnDB who has helped me with manuals and diagrams. The engine was a nightmare to fire up. White smoke and running very rough until it eventually fired and once it...
