Removing the oil (cast) pan from a E280 Hinomoto

Steve Bach · Jan 6, 2010

Has anyone had any expirience removing an oil pan from a E280 Hinomoto tractor.. The pan is not your traditional sheetmetal type pan, it's cast iron. it mounts horizontally and vertically,
and bolts for attaching it are as the same.. I have every possible bolt removed, I have gone over and over every inch of the perimeter of the pan. I can get a screw driver in the front and drive it in and it spreads apart about an 1/8 of an inch, but the vertical attached part will not come loose. If there is anyone that can help me
(before I break it) I would really appreciate it.
Thanks Steve

I am not at all familiar with your tractor. That being said, on some, the motor attaches so completely to the other components (front axle and torque tube), that you may have to split the tractor to find the hangup. My guess is an aligning pin, or dowel which is hanging up the process. Here is where a assembly manual comes in handy. Good luck.

Steve, I am not familiar with your machine, but some of my tractors have an oil pan that is part of the structure. All of the bolts holding the bolster to the engine block and pan needed to be removed. There is a way to make access easier if this is the situation. You remove the bolts into the block, and replace them with some that are about 6 inches longer. then after removal of the bolster to pan bolts you will be able to slide the bolster back on the block bolts.Hope this helps.

I've seen numerous Hino Trucks and saw the Toyoto 1 Ton dually with the Hino engine at the Las Vegas Fema show so it stands they make a tractor but that is a new one. In all probability the pan is mounted on assembly dowels and they would likely be on the vertical surface both front and rear of the pan mounting system. Cast iron? probably the pan is part of the Tractor frameing and if so the Tractor will have to be split to drop the pan.My advise is ,don't try to force it,you'll break something. Get technical advise before proceeding.

I've got a Hino truck, and I don't think there's any connection between Hino and Hinomoto. I remember the tractors being sold by a local dealer back in the 70's, but don't know anything about them mechanically.

Didn't know about the 1 ton Toyota with Hino engine- it would definitely be worth a look. Hino engines are remarkable- mine is a turbo V4, with 250,000 miles- it can sit for 6 months, and will start on second revolution of starter.

Googling Hinomoto repair manual brings up 1,570 hits- bet there's a book in there somewhere.

Your Hino is a V4? I thought Hino's were all inline engines. Dave

Mine is a 1990 FA- with 14' van box with rollup door. I was surprised at the V4 as well- didn't know there were any V4 diesels around. Pulls better than one would think.

The Hinomoto of which you speak is a Toyosha or visa versa which is out of business it is probaly a brother to the AC5030 and very much like my 5020 and if so you will have do like what was said and that is remove the whole front bolster and seperate the engine from the bell housing before you can remove the oil pan it is all dowelled together believe me I had to get an IT manual before I tackled that job. I had to totally reassemble the engine on an engine stand before I could put it back together. Check with external_link for a comparable tractor for a possible manual. I have an I&T manual for a 5020-5030 that I bought at a tractor show. The oil pan is part of the tractor super structure much like the Massey Ferguson.
