End Play Specifications on a Argosy 20' MH P-30?

[911rs]

Going to replace the seal on the diff. Wonder if anyone has a shop manual that lists the end play specs? I obtained three different shims from GM but they could not tell me what the set up should be. Brad, you out there?

Matt,

Do you know which rear end is under the 20' Argosy? I have the 74 service manual and can give you the info once we know which one it is. The choices from the manual are:

Chevrolet 8-7/8" ring gear
Chevrolet 10-1/2" ring gear
Dana 10-1/2" ring gear
Dana 9-3/4" ring gear
Chevrolet 12-1/4" ring gear.

I'll go look at mine to see if I can identify which one it is and get back to you with more info. I can scan in the appropriate pages once I know which one it is.

Matt,

I looked at the diff and it is what is considered to be a GM Corporate 14 bolt (12-1/4" ring gear) rear end. There is no mention made of needing shims for any reason. Here are the instructions for replacing the drive pinion oil seal:

1: Disconnect the propeller shaft (dah!)

2: Scribe a line down the pinion stem, pinion nut and companion flange.

3: Use J-8614-11 to remove the pinion nut and the companion flange.

4: Remove the bolts retaining the oil seal retainer to the carrier, and remove the retainer. See figure 77

5: Pry the oil seal from the bore, using care not to damage the machine surfaces. Thoroughly clean all foreign material from the contact area.

6: Lubricate the cavity between the seal lips with a high melting point bearing lubricant.

7: Install a new pinion oil seal into the bore, using J-22281. Be sure seal bottoms against shoulder in bore.

8: Install the bearing retainer to the carrier.

9: Reinstall the companion flange, pinion nut and propeller shaft.


You might check your pinion shaft to see if it is scored or worn. If it is you can probably get a speedi-sleeve to repair it with.

Hope this helps.

Brad, Thanks. very helpful info. Went like a charm this weekend. Now I can park on a incline nose first and not leak and fluid. Matt

Matt, glad you got the seal replaced. Would you happen to know the part number for the seal? I need to replace mine sometime this summer as well.

Brad,

I will try I threw out the box. I purchased it at a Advance Auto store.

[911rs]

Brad, I called Advance and they where able to pull the ticket. Brand was "National" and the part number is #2286

[bkahler]

Matt,

Thanks for digging up the number!

What I normally "try" and do is pull the lids off of parts boxes and label them as to what they are for. This way I know what part I used and what part I need to get (or not get) when it goes bad again.

Thanks!

Brad
