D15 brake drum and pinion shaft inner bearing

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I tried to post this earlier but I believe I accidentally deleted my posting when I tried to make a minor correction to the  preview.
My D15 is an early industrial model with a Henry backhoe and front bucket.  It has a shuttle shift.

I bought it used several years ago and the brakes did not work.

I have removed the necessary components following a reprint of factory manual.  The brakes were soaked in oil but the drums had obviously been replaced - no rust on the drums and no rust ridge.

One drum was tight on the shaft but the other drum slides in and out.  The key was in place and I can NOT rock the drum (top and bottom) on the shaft.  I cannot feel any wear on the shaft and I am in the process of removing the shaft for closer inspection.  It appears that the drum may have been bored slightly to big. Am considering reassembling it with Loctite 680 Stud and Bearing Lock. Any other suggestions?

Second related question.
The manual shows an oil tube between the inboard side of the drum and the inner bearing at the differential.  I do NOT have and oil tube on either side but the bearing receives lubrication from the differential.  On my tractor the seal is outboard from the bearing.  Was there a design change? Watched a video on brake and seal service on a D14 and the model in the video did NOT have an oil tube but everything else looked identical.  Any info would be appreciated.

	Have done this on a few of the drums .with no side to side play put 2 light tack welds on drum to axle after you have drum back tight against ring on axle with loctite .
	He who dies with the most toys is, nonetheless ,still dead. If all else fails ,Read all that is PRINTED.

	I was able to remove the pinion shaft from the housing. However, I found the illustration of the pinion shaft in the repair manual very confusing. It was NOT clear from the illustration that there were two bearings on the outboard side of the drum supporting the pinion shaft and that the oil sleeve/ tube was in between those two bearings. The illustration appeared to indicate that the oil sleeve/tube was inboard of the key that keeps the brake drum from rotating on the shaft.
