Robert Pearce Starts to restore

[hrpearce]

Hi Harry,
Thank you for the advice, I checked and I have the ring. I plan to make locking tabs to tie the bolt heads together.

The original seal on the rear had a metal flange that covered all 4 bolts and held the seal. I'll try to get you a picture of it.

Harry as you can see the flange is a reck after the bolts were bent . The seal with flange is listed as discontinued so I had to buy modern seal and a bottle of 609 to stick it in with

[Harry Moon]

This is the condition of probably 80% of the cmp trans I've come aross. You have to be real careful and put the bolts in the flange facing rearwards before tightening it up. It is to easy to put the output flange on and then put the bolt and nut on when putting the short drive shaft on. I almost broke my one good one as soon as I put it in.

We had the same situation when we replaced our tranny seals. We could not source a replacment seal with the sheet metal flange. Luckily our sheet metal flange was good ..... we basically drilled out the old flange on the spot weld and used it as is to hold the seal in place. In a pinch one could cut a flange out of 20 ga sheet metal as a substitute. We were concernd that without a flange the seal might move out.

Like Harry, and thanks for his insight fromt he Convly magazine, we looked and found the elusive ring...... but it seems that the yoke bolts do work free with time....like 50 years and can them strike the bolt heads of the tranny rear cover with varying devastive results.

Interesting to note that early rear casting had the speedometer gear hole machined and plugged when not used.....as shown in Robert's rear cover.... as the cable goes to the transfer case. It seems that later in production... cheaper white metal castings were eventually produceed with the same provision for the speedo cable BUT knob for the speedo cable was left blank and not machined...... probably castings made exclusively for the CMP 4x4 as opposed to early off the shelf Civvy type.

Needless to say the cheap white metal castings really desintegrate when the bolts are hit by a flange bolt at full torque.

The other weak area of the tranny casing are the two "ears" at the front that allows the top 2 bolts to connect ot the bellhousing.... but hat is a different story again....

At last I've re-sealed the spare transfur case. The first problem was there are different sizes for pto seals and the one I bought was too small for the holder on this case so I had to rob one off a spare pto. I used spedy sleaves and a two part epoxy steel to cover the groves in the flanges.
My aim for tomorrow is to swap the transfur cases, install the new handbreak and if all goes well re-seal the back of the gearbox.

I amed high but Murphy's law brought me down . I lost three hours this morning chasing spy ware out of my computer and restoring it to a useful mahiene again I did drive out of the shed and lift the cab frame off the back of the chassis, I then drove back into the shed and removed the transfur case. It's a real bitza, Ford case and as Keith pointed out a front drive for a PTO which means no breather . A front drive flange was used for the rear output whch ment the brake drum was between the flanges instead of on the transfur case side of the output flange . A ring had been brazed too the drum to keep the band in place. The best luck I had today was with the jack shafts oposite ends of both myne were worn so I was able to make one like new shaft out of the two at zero cost
