 Topic: Combine engine in a WD
Posted: 29 Sep 2013 at 6:48am |
|
I bought a WD to make a pulling tractor for my dad , the man I got it from said it had the combine engine in it which should have plenty of power. We only pulled it 2 times it runs out of power. I'm not sure if it has the combine engine. How can I tell the difference between the standard WD engine and the combine engine ?

Look for numbers and letters stamped on the left rear ENGINE flange or on a pad on the side of the block below the air cleaner and report back.

I am not having any luck posting pictures and I have not found any numbers stamped on the block.

Thick head, External oil lines, oil filter. The actual front cover may have came off a WD, alot of the time the front cover is swapped. Again, the S/N should be between the carb and the rear of the engine.

It does have external oil lines and an oil filter. I will assume its a combine engine. It runs great and turns a lot of rpm's, and seems to have power. We pulled Saturday in 5000lb class and it ran out of power. I also pulled my d-17 In 5000lb and it had way more power. Just checking to see if anyone has any ideas for mor power .

With stock tires, that engine should do well at 5000#. I ran one last year with 16.9x26 tires and could spin out hard in the 5000. Don't overlook the obvious, carb, ign. timing, valve clearance etc... When I say external oil lines I mean two running from spin on filter with female threads, (the WD and WD45 have male threads) horizontaly to around the dip stick, around 5/16 in size. I am not refering to the 1/8 line going to the head and governor box. I just bought another "combine" engine, I got to go pick it up this week. I will post some pics of the differences.

My first combine engine was a running engine when purchased. It was very dissapointing, we checked the compression on it after a couple of pulls, it was way down. Those engines were operated in the harshes conditions there could be, with all the dust and they wide open all the time. I have a pullin' buddy that took a fresh WD45 engine out to replace with a running combine engine with the "Z" code and it hurt his HP. Again, it needed rebuilding. I am not positive but I think it should be around 100 to 115 psi cranking compression.

Depending on which Gleaner "E" engine you have ( compression code Z or V or M) it will be 140 psi up to 180 psi. ...110 to 120 psi is WD45 compression.

Thanks for the info. I will check the compression on it this weekend and report back. I thought the engine was really good , because there was absolutely no smoke .

All spark plugs removed.....throttle wide open.........battery charger on the battery to keep cranking speed consistent.

Yes it does. You have to make a block off plate. I have a post in the farm section with pics of all the differences.

Thanks for all the responses to my question. I have had a chance to check the compression on my tractor and it is about 65 lbs. my gage might not be up to par so I checked the compression on my d-17 and its about 125 lbs. Also the head thickness is the same as my d-17 . Is it a worn out combine engine ?

I would think with it that low it should smoke. Did you ever try it at dark with a flash light aimed at exhaust ? I'd still say it needs a rebuild. If it's a puller maybe look into something a lil bigger. It don't cost a lot more than a stock build. Just a thought tho. Shawn.

Sounds to me like someone ran a compression test with the throttle at an idle!!!!!!!! Throttle has to be wide open for a good compression test.

Yes, you are correct. I forgot to open up the throttle when I checked the compression. I'll check it again and report back. Thanks for the reminder.

I have rechecked the compression on the WD with the throttle wide opened and it is still reading about 65 lbs on each cylinder.
