yes I am a mechanic but I live in western Canada

I just done a engine rebuild on a 4jb1 in a 853 used a rebuild kit from china got the whole shebang valves, pistons, crank. Didn't use the liners as mine were good.It has been a couple years and everything is working great although I don't put a lot of hours on it. I took the engine out with out...

there are some pretty small holes drilled in the carb doesn't take much to plug them up can be a real pain with a tank that has a little contamination just because your fuel bowl is full doesn't mean its getting through the carb all you need is spark, compression, gas to make it run

the carb has some very small holes drilled in it doesn't take much to plug them up all you need is spark, compression , gas to make it run

A pertronix electronic ignition system would eliminate the points and condenser they work great for around $125 bucks no setting points with better spark. I am thinking you are getting some crap out of the gas tank maybe try cleaning the carb again and try running it with a temporary tank. Maybe...

I am not to sure of the size of the alternator on a 610 but I go the wrecking yard and get an alternator off a geo metro nice little unit 50 amps easy to hook up have eliminated a few generators with them works great

what year did they put a Kubota in a 853 thought they were Isuzu engines little harder to find parts for then Kubota. Thinking if its not an injector rod brgs could next on the list

That rubber piece looks like the diaphragm out of the pcv valve

Just went through the same issue. I think the best way to repair this is to stick with the 4jb1 engine I bought a complete engine rebuild kit from eBay [china] for just over $800. I have not put a lot of hours on it yet but the machine runs great

I recently bought a 1500 case skid steer that came with a vh4d Wisconsin engine from the factory. some one has modified it to a vg4d engine compression was 25, 25, 25 and 0 pulled the heads off and it looks like the valves are stuck or not closing completely .I am going to pull the valves out...

I got lucky took off the purple wire off the gauge shorted the gauge quickly to ground it went to full checked resistance through sending unit 125 ohms, thought that should read 1/2 tank on the gauge I hooked the purple back to the gauge it read 1/2 tank. not sure what happened the machine has...

Its the 4JB1 engine with the east west configuration. I tried the weld, regrind on the crank but it was going to cost as much as a new crank. From izuzu $2600 Canadian so went for the $300 one. The original liners were in very nice condition so they were the only parts I didn't change, the new...

izuzu engine rebuild update. Crank shaft was beyond repair so ended up buying engine rebuild kit from china everything went together very well. The kit included pistons, rods, crank, liners etc for $820 usd. The rings,brgs, were all from japan gaskit set was genuine izuzu started rite up runs...

I have a bobcat 853 with a 4jb1 engine that spun a connecting rod bearing. long story short I need a new crank and connecting rod. Has any one used the Chinese rebuild kits from eBay?The skid steer is not used a lot so I don't want to put $ 8000 to$9000 of parts in to it. I am worried about the...
