Friday 13th January 2012
Besides giving plasma at the Blood Bank this morning learned that as well as today there are 2 more Friday the 13th's this year. Meanwhile at the workshop the elves, although I thought Christmas was over, had been at work. Or was that just one elf by the name of Wade? Whoever it was, they'd repaired a leaking oil pressure gauge fitting at the rear of the block by removing it, cleaning it and re-installing it using thread sealing tape. No more leak there now. Come to think of it Wade does have an aversion to leaks so the finger is turning in his direction. Apparently it also looks like there is a slight coolant leak from the front of the engine but neither under car or on top close inspection could pinpoint the source. Will keep a close eye on that situation in future. Then took the Coupe out for a test drive as well as filling up with 95 Unleaded and returning via George's workshop. George was able to inspect and test the Coupe for it's annual inspection certificate. The inspection approval is now done on-line so I was able, on returning home, to log on and make the required payment. The Coupe is now officially "on the road" for another year. Wade had earlier taken Juniors mainshaft around to Brookers Brake Service so the fitting at the front(see pic) cab be machined off in their lathe. Reason being, Wade had been in contact with his "favourite Packards Parts supplier" but a combination of sticker shock and other factors has led to other alternatives being examined before any order is placed. Left Wade completing the "engineering drawings" for the machining required on the 426 waterpumps.

The composition of the "buttons" differed depending on position to give the optimum frictional properties and hence ride quality. Antimony/tin/lead alloys, bronze, & rubber were all used. I think the attachment, a page from an article I authored for The Packard Cormorant some years back, will give some insight.

Mal, there you will find a similar question followed by explanation especially related to a 1941 110 Business Coupe.
Quote: ...Antimony/tin/lead alloys, bronze, & rubber were all used... Dave, is one of the mentioned separator materials or a compound of it called "silenite"?

Selenite is a crystalline form of gypsum (calcium sulfate) as I recall. Silenite is perhaps a trade name for some proprietary substance.

I am interested to learn of what you and Wade find of this pressed swaged collar in the main shaft. A friend in Texas used an NOS main shaft assembly that ended up reciently having an issue where the collar moved allowing second and high to both engage the sliding shifter clutch resulting in shelling second gear freewheeler on the main shaft.
My transmission clearly had second gear freewheeler on the main shaft replaced as well as the input shaft. This was not evident or clear at first because I took a quick look at the input and freewheelers, and cluster which all looked good. Latter I looked at the sliding shift collar and first reverse slider discovering they were destroyed. Puzzled I looked very close at things and found the second freewheeler to be literally brand new. I noticed first / second freewheelers were loose on the bearings/ main shaft and pressed the collar back further. This took up the sloop and the gears ran perfect. I figured staking the collar would ensure it was tight and did so. It actually moved again and loosened. This was very alarming because I feared it slipping (and rightfully so as I learned almost immediately latter about the one that did in Texas) and the freewheelers moving. I ground a groove in four of the splines and TIG welded a tiny bead of weld in each to hold the collar in place. My guess is the main shaft could have a groove machined into it and a circlip used to retain the freewheelers. If needed, I suppose the gear stack could be shimmed to get the correct bearing clearances. I apologize for not sharing this info in my post on the '40 work progress, but figured no one would get that far into something like this and would just think I was some weird mad scientist mechanic.

Very interesting Jim, a friend in Texas recently suggested "....Repair of mainshafts may be a subject of conversation with Peter Toet as well as Jim (39Super8), who just repaired 2nd gear on his - as well as repairing hardening issues....". I'll certainly pass on what is found when the mainshaft comes back from it's machining.

Hi all, I have removed and replaced the collar on a number of mainshafts without a failure. I grind a nick into the collar then split it with a sharp cold chisel. To replace the collar I use a hacksaw blade at the split to relieve the cut. I then push the collar back into the groove position and clamp the collar. I then MIG the clamped together split and allow it to cool. The collar cools and shrinks onto the shaft behind the groove, in its origial position. It works for me. Best regards Peter Toet

First thing I noticed on the bench this morning was Juniors mainshaft with the gears separated from the shaft. Brookers had been able to cut the retaining collar away then, on Friday afternoon, Wade had presssed off the gears and bearings. With that step completed successfully, step two is to get the collar cut off the donor trans mainshaft. So first up took the mainshaft round to Brookers and left it in Col's capable hands. Plan is to utilise the gears off Juniors mainshaft on the donor trans mainshaft. The synchro's will also be replaced and any other matters needing attention taken care of at the same time. Wade is thinking of going down the path of having a groove cut or ground in the shaft and using a strong snap ring to retain the gears on the shaft instead of welding things back in place. John has given Wade the name of an old-time transmission rebuilder who should be able to do what is required. Back at the workshop, after returning from Brookers, settled down to cleaning parts for Junior while Wade busied himself perfecting the blueprint for the 426 waterpump machining. Cleaned up the tappet covers, front engine plate and timing case cover by initially cleaning with old stale petrol, then brake cleaner, then the wire wheel and then, if required, the blasting cabinet. Found the tappet covers had some minor rust damage so replaced Juniors with the pair off JohnM's old '39 Six engine and cleaned those up instead. That's all I did today, it's surprising how long it takes to clean things properly. Also cleaned Juniors bellhousing using the same technique, except for the blasting cabinet! You really get to appreciate how heavy a bellhousing is especially when holding and manipulating it on the wire wheel. How heavy? Bloody heavy! Meanwhile Wade was involved in a number of aborted attempts at putting together a decent blueprint for the 426 waterpump machining. Finally, after many magic words of frustration emanated forth, I had to tell Wade to take a break, have a coffee and come back and start refreshed. Appeared to do the trick because soon thereafter Wade was also cleaning parts. Attach file: ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]()
