I recently bought an OC46 3cyl. gas. The left rear drive wheel had some wobble to it so I tore it down to find the spindle for the hub loose in the housing. Is this a press in spindle or do I need to look for a housing? Is there any fix for this?
Any thoughts or ideas welcome.
Thanks in advance,
Eric
It is a press in spindle . The best fix is to have the housing bored and sleeved .
Walter
Thanks Walter. A friend of mine can bore it for me. What would a guy use to sleeve the housing with? Just bore slightly oversize then heat and insert a piece of stock and then bore that slightly under the spindle size. I'll be removing the housing today, should I expect to see the spindle in good shape?
Thanks again,
Eric
Turn the spindle down also to get a true fit . After pressing the spindle in ,weld it to the housing on the outside using a cast rod .
Walter
I got the housing off and found that someone had welded the spindle on in two small spots. I'll get it cleaned up and off to the machine shop.
It seems like everywhere I look at this crawler there's something that needs fixing.
Eric
Walter, looks like we posted at the same time!
I thought about welding and guess I will after I get a tight fit. Is this a common occurrence with these machines? The other side feels tight when jacked up and checked with a pry bar. I need to get this thing back together so I can use it this fall for a couple of weeks. One more thing, can I get the seals for the hub locally or do I need to talk to Zimmerman. Don't know if I'll be able to read the numbers on the old ones though.
I'll have plenty to do on it this winter,
Eric
You can get the seal from Landis as cheap as anywhere else .There are two seals .The large is rather expensive,about $40. The stub shafts are originally spot welded in .
I do a lot of seal business thru work with a place close by and was hoping they might have them. Anybody happen to have the numbers? If not, I'll have to measure and choose from the book or just go with Landis.
I should be done cleaning up the bore on the housing tomorrow and then I can turn the spindle down and make my sleeve. I'm also looking for an opinion as far as fitting the spindle to the housing. I figured to press the sleeve on to the spindle then turn it down to about .001" to .0015" over then heat the housing up a bit and slide the spindle in. Is .0015" too much considering the housing is cast iron? I'd hate for it to crack when it cools down. I wouldn't be concerned if it wasn't cast.
Thanks,
Eric
The couple that I had done ,we pressed the sleeve in the bore and then the stub shaft. I dont think heating would be necessary but be sure to weld the shaft in .Be sure the sprocket is not bent .They will rub the pinion bearing cover .Sometimes this causes the stub shaft to get loose .
Walter
I turned the spindle, bored the housing at my buddy's place and pressed the spindle and sleeve in with a little loctite green sleeve retainer then welded it it up. Should be good! Also, installed ring gear and checked preload on the bearings. Did the same with the pinion shaft. I should see the seals Monday or Tuesday. It looks like I'll be able to haul it up north this weekend to do some work. I would like to have the new spool valve but, I'm waiting to hear from John on that. I'll make sure to check that sprocket for runout too!
Eric
Did you yake the valve apart ? Check the relief valve for trash or broken spring.
Walter, I pulled the spools out and polished them up on the lathe slightly. They are pretty bad, not smooth and polished looking. I had isolated the cylinders earlier and they didn't drop a bit, that's why I pulled the spools. I didn't pull the relief valve though, didn't think that would cause my bucket to drift down. Even at idle the hydraulics work great so I figure the pumps strong. I guess I'll check the relief valve for the heck of it and see what it looks like. I want to change the hydraulic fluid this week, can I use the HT stuff from work?
Well, that's enough for now.
Thanks, Eric
