C-120 Automatic - Parking pawl replacement

[Bar Nuthin 186]

The directions to replace the parking pawl seem pretty straight forward. I have the pawl, gasket and a new axle seal (if needed).

Does anyone have any tips they'd like to share before I attempt this?

DO use a proper ROLL PIN PUNCH. 

 

Have new wheel seals handy. 

For that matter all 4 seals. 

 There might be a seal around the pawl shaft. I may have one here if needed.  

 

 

DON'T coat the case half gasket (or any other) with any silicone or other sealer. 

 

Install a magnetic drain plug.

@ebinmaine I hadn’t considered the pawl shaft seal(s). I’ll do a deeper dive in the manuals.

@ebinmaine I'm only planning to pull the RH case.  I can only come up with the Axle Seal, the Brake Seal, and the housing gasket.

You reference 4 seals - what am I overlooking?

 

If you have a brake shaft seal, I will gladly buy it from you. Likewise, if you have an extra magnetic drain plug.

I was figuring:

2 axles seals. 

1 brake shaft seal. 

1 park shaft seal.

I have several New Old Stock CR 4911 seals. 

 

 

I have a few magnetic drain plugs but they stick DOWN from the case. 

I'll be buying some that set flush as stock ones do. 

You may be able to find one of them at a local store. 

Another option is to get some Rare Earth magnets and simply stick one the the bottom of the case.  

 

 

 

This is one of several ares of my not very well-organized Parts Department.  

 

 

 

PM me your address. 

I'd be glad to send a seal. I'll treat ya right.

Before you even think about going inside a transaxle be sure everything is spotlessly clean.

Very generous of you!

I guess I need to rethink this.  What is the difference between the brake shaft seal and the park shaft seal? To my limited knowledge, my C-120A doesn't have any brakes, Only the parking cog.

Since I'm only planning to pull the RH side off (leaving the internals intact) I can only identify

• 1-RH axle seal
• 1-parking shaft seal
• 1-RH case gasket

I have the gasket and axle seals, and I'll grab a drain plug locally.  I'll send you a message on the CR 4911 if you don't mind parting with one.

Thanks again!

That will be more challenging than the actual repair!
