Drilling axle cotter pin hole

Is it OK to drill out the main axle cotter pin hole to #30 so that a standard 1/8 in. Cotter pin will work?
 
Jim, I ordered pins from Van’s a while back, but they wouldn’t fit. They were barely too big. I’ve had trouble finding the correct part number for this part. It is not identified in the RV12 construction manual.
 
Do you any tools to measure the hole? Perhaps use a drill bit of known size to test fit. Then yes, buy correct length...
 
The That?s a good idea. I?ll see if I can determine if the hole is actually a tad undersized by seeing if a 1/8 in bit will fit through it. If it won?t, I?ll try a 7/64. I suspect I?ll end up getting a 3/16. I will probably end up getting the MS24665-289. But I wish a few more people would respond and tell me PRECISELY what they used. I think I?ll call MATCO tomorrow since the axle and associated parts are their products. I?m sure they can tell me. As I was researching this, I did run across another part number for this cotter pin on the MATCO site: MSC.125X2COTTERPIN. Someone said that the ?.125? indicated 1/8, but it is actually a shade smaller. It was mentioned that this the pin MATCO actually supplies with the axle. I just wasn?t sure that this particular MATCO axle was the RV12 axle.
 
Sorry, don?t know the part number of the cotter pins off hand.
I just have a storage bin full of them I have been pulling from for years.
However, that?s probably the correct one.
 
OK. I called MATCO this morning and they told me that the correct cotter pin for the RV12 main axle is: MSC.11X2COTTERPIN Z/P. Trouble is I would have to order 55 of these to meet MATCO?s minimum $10 order. Does anyone know of a different source for these?
 
"The part number for the cotter pin on the axle nut is the MSC.11x2COTTERPIN. It is on our website at:

It is steel and is clear zinc plated.

The same size steel pin (7/32) from other sources would work fine.

The wheel on the RV-12 is the MHMHE51B. The axle assembly is the WHLAXLE3A. They are on our website at:

Both links provide additional details.
