Cross Joint problems

Hello again guys... new problem. I need to replace the cross joint on my 1985 XJ 700... Didn't check yet but I bet is going to be hell to find that part around here so I was wondering if someone has a cross reference chart for this part... Maybe be is the same part for a Virago 1000 of the 80's or some like that. I hate to install a cross joint of a car mainly because that mean to adapt that part for the bike... Thanks again...

you can look up any bike if the part number is the same it will fit. if you click on the part number it shows what bike too

Thanks xj550h, all those model that will fit are equally hard to find here...and in the boat section that part is 570.99 is crazy...I'll probably have to make it from scratch with a shop machinist... or get in the cars parts catalogs and try to find something to adapt...anyway thank you for your help... and I let you guys know what I'm replacing this part for...

 

Hey Rod, w do have them in-stock!

 

Hi Chacal...I know you have it... the problem for me is to get it here...there is a lot of restriction with the stupid customs we have in this country. So probably you'll send it and I never get it or get it paying a 100% tax...
As far as I can check yesterday the cross joint is the same as a directional cross joint of a Renault 12. The part that holds the cross joint in place is damaged but I can send it to a machinist to re-fill it and make it new again. I was damn lucky I didn't kill myself in the bike the cross joint was way beyond severely damage it was about to pop out and lock everything.

 

But maybe you can tell me if this cross joint is made to work dry... I mean do I have to spray oil once in a while? Silicone grease? something...?

 

Here's why I almost crash with the bike...or worst...

 

the end caps should be packed with grease, just like any u joint. you could drill into it and put a grease fitting on it where the holes cross.

 

Drilling won't make the material/part weaker?

 

Yep, that was death waiting to happen, glad you found that! I wouldn't drill it, but you can replace the bearings with ones that have a grease fitting.

 

any drilling and tap for fitting will remove material and possible weaken the part, if you look at ujoints you will see they drill at the junctin of the cross.
I would go with what Chacal stated. but understanding your parts situation it may be your only option, unless you pull the caps off and add grease that way every year

 

Wow that joint is badly damaged. Are you sure to want someone to weld on it and try to save it vs just finding another one? If the metal gets brittle from overheating, you could get another failure and maybe not be as lucky. Is there any crashed bikes in a salvage yard or find a good used one from someone down there where you wouldn't have to wait and get taxed like that?

 

As far as I could find out...the cross joint that may fit is a sealed one so already have grease on the end caps. What its need to be done with the damaged piece is re fill it with a special weld material (I think is going to be an iron mix) and the machinist shop will take care of re do the holes and everything so will be brand new... I look up in internet that part is 567.99 dolars plus tax and shipping. Pretty expensive indeed when you can get Maxims for 2000 dollars in fairly good conditions....
All this process is going to take a couple of weeks...when I got the piece back I'll post some pics....

 

you're going to have to put new bearings in it and the heat from welding will most likely burn out any grease thats on them or ruin the bearing.
i got grease in mine with a needle fitting for the grease gun and went right through the rubber seal. I think a tiny hole in the center of the end cap and the needle might do the same thing, then put a small sheet metal screw in the hole.
keep looking for a used one

 

You are right Polock... the steps will be take the cross joint apart, weld and redo the piece thar hold the croos joint and then install the cross joint... probably and most likely to get a cross joint that comes with what we call "alemites" and that was you said, little fitting for a grease gun so you send grease by pressure inside the caps where the little rollers are, or someone told me already there are sealed cross joint maintenance free... Sadly there no salvage yard allowed in this country nor for cars o bikes....a shame...so we have to work with what we have at hand.

 

Wow, that's really odd. Who's bad idea was that law?

So what happens to all the old vehicles in your country?

 

they send them over here

 

^ serious pucker factor at the end of that video!

 

Love Top Gear.

 

Well...to be honest, law is preventing the salvage yards mostly because there is a lot smart asses that can rebuilt cars/bikes and sell them without the papers...plus there is a incredibly large black market for stolen parts...
Other thing is you can find cars from the 50's still running and running good...so most people do not change the cars just because its old....I can get you a Chevy SS extremely well for 7.000 dollars, or a Ford Falcon from the 60's,70's or 80's (Ford stop production of falcon models in late 50's in US) for 3.000 dollars... and in the other corner a Harley Davidson 883, used, is no less than 22.000 dollars, is crazy but it is what it is here...

 

Hi guys...here's the update....new cross joint... worked perfect... then a spark plug in the 3er. cyl went bad...replaced and now I have to road test it... hope is only that... Ok...back to the new cross joint that was from Dahiatsu car... end cap is 14mm. Also new paint for the tank... The piece that hold the cross joint was refill with a MIG welding and machine shopped again... look like new right? they did a really good job.

 

Impressive , looks great!

 

Looks better than new

 

how the heck did you ever figure that out

 

Polock, It was a researching job of about 3 hs.... measuring the end caps of the old one, and going to the catalogs to check what small car (usually Japanese or Italian or French) could have those 14mm in the cross joint... plus a great mechanist, almost a genius but trouble is He works when he wants to... and since He does no want to work in my bike he gave me directions by phone and I wrench here and there.... Thing is everything was ok until I reach 55m/h when I noticed a little vibration on my feet. So I took everything apart again and I didn't notice before that inside the piece that connect the engine to the cross joint there is a 19mm nut that it was loose, so took it off putted a washer, then the nut, tight it up, put everything back together again, and vibration was gone.... Like I said a time before we work with what we got....
