Exclamation Lord differences.... what do they mean...

Well, not exactly....

They both use a J-12334-1 spacer, and a J-9612-8 rubber block...

...but the -40 uses a J-7763-1 other side rubber block, and the -49 uses a J-7763-33 block.

My Tiger used to use the -49 (for the first 400 serial numbers) but then switched to a -59 which is the same as the two above, but with a J-7763-6 other side rubber block. This change apparently smoothed out vibrations transmitted to the airframe from the O-360-A4K motor (and raised the price 50%.......)

There do seem to be subtle changes in one of the side rubber blocks - which is the harder of the two rubber blocks.

The no longer around -45 part I mentioned above is similar, but uses a J-7763-10 hard side rubber block.

I wish that Lord would give a better description of what the actual changes in the rubber blocks are... which one is harder? ....by how much?

So.. the choices seem to be...

J-12334-1 spacer
plus
J-9612-8 soft side block

hard side choices...

J-7763-1 - salesman
or
J-7763-10 - original Vans
or
J-7763-33 - salesman
or
J-7763-6 - possible upgrade (Grumman) from the -33 part...

...and all seem to be applicable to O-360s.

PS - actual data from a Lord Technical Reference LB-571 document found on my copy of "Mechanic's Toolbox" from Vans, made by Sacramento Sky Ranch. The only place I could find real data....

PPS - for over $400 I would like (actually, expect) the best part if I pay the Lord premium...

Per the above quote:

...use J-9613-40 or -49. As he put it 'which ever is cheaper'


If still in doubt, call Lord tech support.. they're very helpful.

PS.. I went with -40...

From what I I get from Gil's post, the -40 & -49 are for the 0-360 engines:"...and all seem to be applicable to O-360s.", mine is an 0-320......

I just ordered a set from Jeppesen as well at 105.71 a set so the price is still good. Vans wanted $125 a set and skygeek wanted 147 a set.
