The Rebuild

[Phil Waterman]

Though before you install the box. With the modern equivalent for the SAE 90 called for in the manual all three of my CMPs have developed steering box leaks. Original lube they didn't leak even when full, clean boxes all new gaskets fill with SAE 90 they leak like sieves, particularly around the large adjustment nut at the bottom of the shaft.

Consider checking for leak before you get the box in the truck (easier to clean up the leak).

Now for the rest of you living in warm climates what are you using in the steering box and does it leak? Or have you found a good way of stopping the leak? Or is this a problem only on CMPs in New Hampshire?

Phil,
Down here in sunny Arizona (where it gets hotter than the hinges to Hell) I use Valvoline SAE 80w90 Gear Oil in my F8 steering box and have had no problems with any seepage.

Regards,
Jim

.... Hi Phil

Mine was good and tight and is one of the few parts I did not fully disassemble...(yet) I topped it up with a heavy thick Lucas synthetic gear lube and it does not leak........ well not like a sieve anyways...... the OD flat paint tends to show oil stains at the smallest possible leak....... but it is not dripping.

On the other hand, my totally rebuild T case with new bearings, bearing races, modern seals and Speedy Sleeves on all shafts.....leaks.... not enough to be a concern but the bottom section is shinny and usually has a drop hanging there......... and it is filled with synthetic oil.....and I knew that the synthetic oil might leak...... after all it is a CMP.... why should I deprive it from marking its territory. Same story for the tranny.

My 45 HUP's steering box was found to be filled with grease!! I cleaned it out and filled it with gear oil only to find it leaks like a sieve...The grease option is starting to look good...

The stearing box on the blitz leaks badly, the new paint stedied it a bit.
I haven't checked the oil in this one yet but if it looks like leaking too much I'll fill it with chain oil it lubricates well but is quite sticky and needs a fair gap to leak from.

...... it was common practice to fill M 37 Dodge steering box with grease as they were bad leakers also........ and we use to top out trannies with the then famous STP....about to cans...... worked great until the following WInter at minus 25C the tranny would not shift as the oil was almost solid.

I wondered why the stuff that came out of the steering box so thick, it was thinner than grease but thicker than gear oil.

Which means the solution to my leak problem is probably to pump it half full of grease to mix with the gear oil and just keep adding grease until it stops leaking.

I'll have to check the service bulletin book to see if it mentions this.

Time is running out so I swaped the stearing box this afternoon it is full of chain oil and still has a slight seap but it's not bad enough to fix yet. I must have lighned the splines up OK as I still have both locks.

Went to Wagga this morning to pick up the T rubber I ordered for the windscreens. While I was there I bought another two profiles and used them to seal the hatch and take the anoying noise out of it. I got the pasenger windscreen cleaned and painted and the drivers side cleaned and one rusty corner patched with quick steel. Lastly I mounted a switch in the dash for the wiper.
