A common error when doing brake relining on cars with the trunnion block, at least the ones with 2-shoe brakes thru 1936, is to use the same brake lining width on all four wheels. If you check your specifications you'll see that the left-front wheel used a narrower lining, 1/2 inch narrower on the Eights and Super Eights and 5/8 inch narrower on the Twelves (data for 1934).
EDIT: Yes, of course I should have picked up on it. If the car is RHD then the trunnion is on the right side and that side then I presume has the narrower brake lining.

Tom, Yesterday, Wade did mention it's called a trunnion block but I couldn't recall the term so left it out of my narrative, thanks for the background to it's development and usage. On Kevin's '35 it is on the right front spring probably because it is a RHD car. Tom and Howard, I think I've found a supplier of switches closer to home, Dick Smith Electronics, an Aussie electronics chain see link.search.dse.com.au/search?w=tilt+switch&x=0&y=0&asug=&sessionid=48c1980600806e82273fc0a87e01069f&ts=new Quote:
And Dave, I had noticed the difference in brake lining size in some research for other matters and was curious as to why, now I know! To all you guys - A BIG

Was sure you would find something close. The mercury switch looks about the same we have here and rating looks good. The rolling ball looks marginal. If you choose that one, would suggest checking how many mA your lamp draws at 6V. The 20mA rating of switch isn't very much.

Trunnion Block.
Referring to Tom's comment that the trunnion block was introduced on the 1930 7th Series cars. At the risk of being picky, the trunnion block was introduced on the 1929 6th Series. According to the Turnquist book it can also be found on some late 443 Series (1928). Turnquist also says that it was invented by a Frenchman and the right to its exclusive use was purchased by Packard. The trunnion block is on the LHS of both of my 6th Series cars, they are both RHD.

David, I don't think Wade's '34 has a Trunnion Block either side but I'll check next week when I'm back in the workshop.

David Thanks Dave for that observation. I guessed (perhaps incorrectly) that the trunnion would be on the steering side. But a last question, were your 6th series cars built as RHD at Detroit for export, or were they converted locally? I think the answer to that would conclude the question.

David,
Thanks for the correction on the series number. My memory failed me, and it was the 6th, not the 7th series where it first appeared. My source (the Kimes book) seems to indicate that it was a Packard development: "A happy accident had seen to the adoption of the 'loose trunnion' mount for the rear end of the left front spring. During testing, one of the cars seemed to be free of wheel fight and shimmy when others were not, over the same test road. Examination showed that the left front spring rear mount was loose. This led to the design of a rocker mount held in place by four short compression springs, ..." Anyone know of any other source to corroborate either version of events? Tom

Trunnion Block,
I should have checked before stating that the trunnion blocks were on the LHS on my 1929's. I just checked , both cars have the trunnion blocks on the RHS same side as the steering box. These Packards were fully manufactured in US as RH drive cars before export to Australia. Sorry about the misinformation. As for the origin of the idea, I would suspect that Beverly Kimes was aware of the much earlier comments by Turnquist and her research revealed different information. Interesting. David

Started by jacking the right side of the front suspension up because currently the '41 is sitting on jack stands and the front suspension is "hanging". By doing this the gap between the sway bar and the mount on the front suspension was shortened but not enough. So tried the same on the left side with of course the same result but while doing this thought I may have mounted the sway bar upside down........ And why don't they fit? Because they appear to be for '48 - '51 Packards as I just found on eBay! See pic's Attach file:  (27.00 KB) (6.78 KB)
