Bell crank woes

Yes, the kit included the two dust seals. The dust seals, pinch bolt, bearings, and bearing sleeve were the same as what I removed but the sector shaft was different. With the shaft torqued down the bell crank would bind to the point it wouldn't move. I re-installed the old shaft and it works fine. The kit came from Walck's and was advertised as "Bell crank kit 7/8" 2A, 3A, 3B, CJ5/6, DJ, FC 150, M38, M38A1 up to 1966." There was no spring washer or boot included.

See page 8 Photo Gallery,my album with name sinrisnekaf page 2 there are 2 photos on the bellcrank. Hopes this helps.

Note: The parts of the bellcrank M38 and M38A1 are equal to each other.

The kit in your picture appears very similar to the one I received from Walcks. It's impossible for me to tell if the sector shaft (large bolt) is the same dimension and proportions but it certainly looks like it - including the hole in the end for a cotter pin (original did not have cotter pin). The only obvious difference with your kit is the inclusion of that larger rubber seal/boot.

Edit: Your kit also does not include a spring washer. Where did that kit come from?.

Yes, that is a CJ kit which can be used on the M38/M38A1 but you have to use the old bolt for the needed length.

You should check with MWM, AJP, Rapco & Ron Fitzpatrick military jeep parts for the correct new bolt, washer and rubber boot.

My M38 was assembled but I did look at a spare M38A1 frame I have and the raised collar that is smaller in diameter then the rest of the bracket pinch bolt area appears at both top & bottom ends and is machined into the steel. No bushing from Willys. I would guess the Cj's don't have the machined extended collar. This would account for the shaft length variation.

Sorry for drudging up this old thread, but I've run into the same thing on my M38a1 CDN.

Here's the difference, though - the old pivot shaft that came off of mine was the same length as the new one I ordered from kaiser willys and had the cotter pin hole at the top. I'm guessing someone had already installed a repair kit with that length of bolt.

The old bell crank had a lip that was machined out (not sure if after market or not) that went over the piece sticking out of the bottom of the bracket. Here's a pic of the old and new bell cranks (new on bottom of course):

Bottom line is - what is the solution? Can I use washers as a shim? I haven't found a bell crank that actually matches the old one.
