Need help in Nashville, Tn. Update

Bob & Tracey · October 13, 2015, 12:07:28 PM

The bad news is we need a differential. Anybody know where to find one for a 4106? I do not know the ratio but we turn about 2100rpm @ 60mph.

Thanks

Now would be a good time to buy you a 4:10 and not go back with a 5:55 or what ever they were.I am going to check for you if he hasn't sold it for scrap I know were a 5:47 is

Like Clifford says. It would be best to go with an 8/33 4.125, that will give you about 60 at 1800(I think). Don't know where one is, but I'll make a couple of calls

The differential should be the same as a 4905, 4107, 4108. Only two ratios- 4:11 and 4:33. About 4 to 5 mph difference at 2200 rpm. Luke should be able to get one.

Stock ratio for the 4106, 4107 and 4108 was 4.125:1

The 40-foot 4905s came with a 4.375:1 ratio.

FWIW & HTH. . .

I found one in Georgia in a 4106 that's getting parted out. He can't pull it until this weekend to check the condition though but its geographically relatively close to TN. I'm not sure if he sent you a pm or anything but I wanted to let you know we have one available to you.

Watch the ratio you are going to be a lot happier with the 4:10 so will your DD and the pocket book I think one from the transit models work also like a 5303

Bob & Tracey · October 14, 2015, 06:40:35 AM

That is awesome Scott, I will be waiting to hear from him.

Bob & Tracey · October 14, 2015, 06:42:49 AM

Clifford, how can I tell what the ratio is?

luvrbus · October 14, 2015, 06:49:55 AM

It's stamped on the end of the pinion shaft

Scott Crosby · October 14, 2015, 08:19:18 AM

I think they were going to contact Eagles Nest and get you their contact info. They just signed up here but don't have login. Lance is helping arrange the deal for you and he owns a 4106 and lives in the Nashville area. The guy that has the 4106 is Bob in Georgia. It should be the 4.125 as that's all Ive ever seen in a 4106 but once he gets it out he will know for sure.

luvrbus · October 14, 2015, 08:38:28 AM

You see different ratios other than a 4:10 in a 4106 his is not a 4:10 turning 2100 @60 mph and he has V730 what are they .875:1 final ?

I recall all the Rocky Mountain Trailways and Greyhound were low geared

Bob & Tracey · October 14, 2015, 08:57:12 AM

Scott,

I sent you a PM.

Do you know when this bus was last driven?

Scott Crosby · October 14, 2015, 08:59:21 AM

I missed that he should be like what?? 80ish mph at 2100 with a 4.10 .875 22.5 wheels??

Scott Crosby · October 14, 2015, 09:23:53 AM

I have a 5.35 I think?? from my fishbowl sitting in my living room as a table. The ring and pinion are in great shape. It was like 54 mph at 2100 but my trans output was only 1/1 that might be closer to what he has now.

I don't know how long that bus has been sitting but I doubt that would be an issue.
