YM336D spindle collar repair

[R Barger]

The part from Hoye doesn't have to be machined but the gear housing has to be to so you can use the part. Hoye needs to note that in the future.

its the housing that's too small, the seal fits either way its the speedi sleeve, that once installed, makes the spindle not fit in the housing. All the seals are the same outside dia. just the inside is available in many size options

Would you be so kind as to post the other seal numbers ? If I could get a seal with a s.taller seal dia. It may fit tight enough around the spindle to stop mine from weeping oil.

Kenmac, if the shaft if scored it will require a tighter fitting seal, and there are several that have a smaller ID, hoye might have the sizes described if u can get an idea of what ID you need. You could also try,depending on the severity of the grooves, some RTV on the inside of the oil seal,. then set the shaft down in,let it sit over night, the rtv is flexible,creates and inner seal of sorts and may cure the leak-

Just an option

Some of Yanmar's lower castings are a little tighter than others for some reason. Most of the time the repair collars fit right in without any problem but some castings will have to be opened up a little bit. Most of the time it amounts to just cleaning up the rough casting with a die grinder. It does not have to go to a machine shop or be super precise because nothing actually fits in that hole. It just has to be made big enough to allow the collar to pass through. I will add some notes to the product's description on our website.

No grooves. It just appears the seal isn't tight enough around the spindle ? where it goes into the gear case housing. I may just add something to swell the seal a little

try the rtv,it might suprise you, rub a small amount on the inside of the new seal, keep us posted

Gear housings are at the machine shop. He checked the sleeve and the housing bore and said the hole would have to be bored out 1/8th overall or 1/16th all the way around. Supposed to get them back on Saturday.

I got lucky as my neighbor has a shop in his barn, can machine anything, made me a tool to slide the sleeve on and cleaned the opening to fit then new sleeve, probably should have done both side but one side only req'd a seal, if u have a chance snap a pic of the housing before it goes back together

 

[grainger12002]

hows the repair going RB ?

 

[R Barger]

Still waiting on the machine shop. Hope to get the gear housings back tomorrow. I will take some pictures and let you know.

I guess I'm still not seeing this correctly, but it appears to me that this is intended to be re-assembled through the bottom plate opening. No machining necessary.

 

[R Barger]

The sleeve is pressed on the spindle housing first then the gear housing is assembled and slides up over the spindle housing.

 

[normde2001]

So, worst case about 30 sec's. with a $2 rotary sanding disk on a drill to remove the 1/16" lip from the gear housing.

 

[R Barger]

I think you would want the opening to be as close as possible to avoid allowing dirt and grit from entering and destroying the seal prematurely. If my freind at the machine shop had not assured me he could do the job your idea was going to be my next step.

 

[R Barger]

Got the housings back today.Got it put back together right as it got dark so I thought I would let it sit over night before I finish filling it with 90w. I took some pictures. One is of the housing showing the boring job.One is showing the housing with the sleeve inserted showing how it fits and the other is the housing with the seal installed.Everything seemed to go together good. I'll check it out better tomorrow.

I hope that solves the problem.... When I replaced my seals. It took a couple months of operating B-4 they started weeping again.... I hope this fixes yours.....Mine isn't really that bad

I haven't had time to work the tractor yet but did run it around for about an hour and everythink seems fine. No leaks so far.Going to mow some pasture this weekend. If it ever has the problem again it will be an easy repair the next time.
