1500 weak front axle?

Postby Jtmachinedesign » Tue Dec 26, 2017 11:58 am

So I've been hearing about the 1500's front axle being a problem... we talking about 2WD, 4WD or both?

My impression (and that's all it is) is this.

Yanmars are engineered for the Japanese market, largely for paddy-frothing where FELs (front loaders) are so rare that I never saw one when I was there. Here, FELs are common. Don't install a subframe, load the bucket to max, drive over bumps, and the front axle, if not the frame, -- which have been undergoing metal strain for almost four decades -- might complain with a loud snap.

Happens to 1500Ds because most FEL-equipped Yanmars are (or should be) 4WD, and the 1500 is a (or the most) popular model. Take it easy with your FEL (and especially with a hitch-mounted back hoe) and you should be OK.

Experience with 1500s or with other models too?

In the subject line of my original question: 1500.... FIFTEEN HUNDRED.
I've seen many time someone refer to a weak front axle.. as far as I can tell, they're all "impressions"
impressions, heresay, echoing what they've read elsewhere...

I'd love some real facts from someone with real experience with front axle failures.

I have direct experience selling parts for them every day and talking to customers that own them. Alan is exactly right. If you have a heavy loader on one you will be calling me (or someone like me) for parts. Otherwise, the axles are built plenty tough for normal non-loader use. This is not unique to the 1500. It applies to most of Yanmars compact tractors for the reasons alan mentioned.

so the axles on the 2WD is the failure point? 4WD gears OK? Bearings?

If you overload the front axle then both the 2wd axle and 4wd axle will be a problem on any of the smaller Yanmars. The failure point of the 4wd version is usually the stub axle (horizontal that the wheel bolts to) or spindle (vertical where the steering arm attaches). Once one of those breaks then it can wipe out some gears. The failure point of the 2wd axle is almost always the "L" shaped spindles. The next point of failure (usually not far behind) is the steering box because steering gets much harder with a heavy loader and the steering boxes were not designed for that.

Exactly what do you mean by "1500's front axle being a problem"? None of these compact tractors were designed to accept the additional weight and stress of a front end loader, which is the only thing that causes a problem with front axles. How much of a problem totally depends on the user.

I've worked mine hard and lifted way more than I should have BUT I do take care of it. No turning without moving when loaded, slow steady movements and not jumping over things when the bucket is full. To date I have not broken anything at all , I guess I have been very lucky. :mrgreen:
