Surely from long hours of heavy use there will be wear, but failures? None that I can recall either. Lube ‘em and run ‘em! 1 Share this post Link to post Share on other sites
ebinmaine 70,393 #27 Posted February 11 @SylvanLakeWH and @Handy Don As you guys are probably aware I've taken apart and rebuilt at least a dozen Transmissions of various configurations. Nearly ALL of them got at least one bearing on one side. I believe most of those were because of lack of lubrication and care as stated. I have however seen a couple that were absolutely positively beat to snot and even bent. Were they extreme situations? Were they in something before I got it that was really working too hard for too long? I'll never know..... Seeing the rated limits in the previous post certainly makes me feel quite a bit better about the future potential. 1 Share this post Link to post Share on other sites
ri702bill 8,925 #28 Posted February 11 A needle roller bearings is thus able to withstand 2 to 8 times more load than ball bearings or cylindrical roller bearings of the same shaft diameter, all this in a small space. At the same time, they are suitable for rocking motion due to the small inertial force caused by rotation. Needle roller bearings are suitable for lightweight, small machine designs, and they can also be used to replace plain bearings. Needle roller and retainer assembly is the main type of needle roller bearing, which includes a needle roller and a mechanical retainer that supports it. In space-required miniaturized designs, the shaft and bearing housing (box) itself act as a bearing ring. It is often used in reciprocating compressors and small engine connecting rod bearings, especially the design of the retainer can be used in environments with large changes in speed, acceleration and deceleration, high temperature, and poor lubrication conditions.

Handy Don 13,266 #33 Posted February 11 1 minute ago, ebinmaine said: @Pete D My apologies for leading the topic astray... Well we’ve certainly confirmed that the outer bearings can handle a heavy weight box! To close the loop, gild the lily, show off, and fully satisfy my curiosity.... A 1533 ball bearing supports the inner end of each axle. Loads are at the wheel (~3” from the B1816), at the B1816, and at the 1533 (~8” from the B1816) so to match the outer bearing, the inner must have only 37.5% of the outer's dynamic load capacity, which I’m confident that it has but specs are not available! So after accounting for all the geometries: to avoid risk of rear bearing failure, keep the load on a moving tractor at or below 11,400 lbs. on the rear axle (evenly across the two wheels). 1 Share this post Link to post Share on other sites
squonk 42,364 #34 Posted February 11 You can hang suitcase weights on the edge of the weight box. No pics but I used to do that with my Power King 2 1 Share this post Link to post Share on other sites
HyperPete 440 #35 Posted February 11 I have thought about this, but I'll have to reinforce the box. The metal is pretty light gauge. 2 Share this post Link to post Share on other sites

You will need to increase the pressure in the rear tires to 110 -115psi. 4 Share this post Link to post Share on other sites
