Problem 4104 Motor or Trans

[dtcerrato]

Don't worry about the loose dipstick as long as it's the inner piece & not the outside unit that plumbs to the block. Our has been real loose for many decades. Have you checked the tranny fluid? I mentioned brake cause both my parking brake and in a different time the both front brakes the anchor pin that the shoes pivot on were so rusted that not even the brake chambers would move them when the shoes froze snugly to the drum. That's pretty fresh in my mind of not too long ago. The bus sat near a job site in the MS Delta for six months of really humid & wet stuff... Just a thought.

The diff ratio is sometimes stamped on the end of the pinion shaft.  Clean things real good and shine a bright light on it and see.  3.55 was not a real popular ratio, mostly used on Trailways divisions in the SW etc. where there were long flat roads and no hills.  I have the 3.55's (out of a 4104) AND the high speed trans in my Silverside and I can still start on the flat with no problem.  Can't back up on a grade though.

Too much work to read end of pinion shaft. Jack up one set of duals and have someone rotate them exactly two turns while you count revolutions on driveshaft or driveshaft brake drum through transmission door. Mark tire and drum/ shaft with chalk.

My 4 speed 04 is just like yours.  It has the tall gear.  on most state highways I just run along in 3rd.

The answer is to learn to drive it that way just be careful where you go and stop.

It is that way as I was planning on a upgrade like boomer has.  A different animal for a 6-71.

But I got a deal in Huggy and solved all my startability problems.

10-4 on keeping everybody posted. Nothing but rain here in south Florida and more commimg. Just look out the window at it now. "The Bus" not the rain.

65 and sunny this morning in L.A.

Sunshine here today also Loxahatchee FL. Of course the weatherman said it would rain. I guess he has a 50% chance of being right or wrong. 90 with some sort of thing being 100. I do not understand the thing. For years and years they just gave you the temp and humidity.
