Moser lists their standard yoke at 1.500 and the bearing version at 1.495...it may be cheaper to sell your old and buy the new one then pay a machine shop.... | |||

wood dowel stock can be used. Shove the yoke over it. Use tape to build it up if the dowel is small. Use 400 wet or dry, it will be fine. | |||

The yoke spec for the roller is 1.4997". You may be able to polish it but it won't be accurate and could create a bigger problem. To get the surface parallel so it can be run on a roller bearing it has to be ground. Hutch | |||

Bad News, Awesome idea, but It has an end cap, so you can’t put the dowel through all the way. Rob Robertson | |||

Hutch, Your referring to surface hardness? Rob Robertson | |||
|
DRR Sportsman |
he probably meant surface Ra | |||

Yes Rockwell check the surface to make sure it is hard enough to run on a roller bearing. Hutch | |||

When in a lathe chuck it wont need to go all the way through. Also great for polishing a used yoke. You are not cutting it, just letting a sheet of paper take some .0000 off. | |||

Bad News, That's what he did. he centered it in the chuck and then used a center for the spline end. Checked it to ensure it was centered on both ends. It fits in nicely now. Hutch, I talked to the machinist this morning and he said he doubted they only hardened the outside, he said they would have hardened the entire end, due to the splines. Which makes sense.

Yokes that are made to run on a bushing aren't surface hardened like the ones intended to be run on needle rollers. You're going to want the specific yoke intended for use with a needle bearing, it will also be the correct size out of the box. .991 60' 4.36 @ 159 so far..... 6.86 @ 198 trying for more...... 533" single carb 235" Harrison 4-link | |||

I have a Mark Williams driveshaft in my car. Ran a bushed rear cover trans for years and switched to a trans with a bearing last year. I checked the fit before I installed the trans and the yoke went right in. The bushing trans scuffed the yoke lightly but always cleaned right up with scotch brite or fine paper... I have not pulled that driveshaft/yoke out since switching to the bearing trans to see what it looks like.... An aftermarket case is thicker at the mounting area and because of that I could barely get the driveshaft in after the swap from a stock case trans.... I was not going to back my 4-link bars up unless absolutely necessary....and didn't....The yoke does not bottom out on the output shaft. | |||

This is true trust me don't ask how I know. | |||

Bringing this post back to life. What are the advantages of a roller bearing tailshaft to a bushed tailshaft? I currently have a dollar bearing one that needs to be replaced and seeing if it needs to go back as that or if a bushed one will work too. | |||

To add to this thread when I went to aftermarket case I went with the roller bearing and ended up putting a Mark Williams yoke in it as the old one would not fit. When I got the dragster it had a Mark Williams slip yoke for bushed tail shaft and would not fit in my transmission. I called them to order one for roller bearing and they did not have them in stock. But they did say I could just turn it down to fit. So I carefully sanded it down and it works great. As for why I choose the roller bearing I just thought it may be better and more durable. Just my opinion and have no proof of it and that is something most people do not have any problems with any way. https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge. Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue. 4X NE2 CHAMPION. 2020 TDRA NE2 Champion | |||

You might want to check it out. When we got my wife’s car the previous owner said the trans was fairly new and it’s a roller tail housing. I noticed the yoke wobbling when she was warming the car up on jack stands. It had a lot of play grabbing it by hand and when I took it out there was a groove worn into it where the bearing rides. So they must have used the same yoke they had with the bushing tail housing and the bearing chewed it up pretty good... | |||

Is there any reason to run a bearing housing instead of a bushed housing? | |||
