Pinion Angle

[SSDDBRONCO]

How does my pinion angle look? Do I need a shim to correct the angle or is it fine the way it is?

Thanks
Kev

I'd say yes. Looks too steep to me and should be closer to in-line with the driveshaft.

If you measure the difference between the two shaft centerlines and come up with something near 9 or 10 degrees offset, then the usual 6 degree shims should take care of it.

Whatever you use, ultimately you want to end up with the pinion pointed down in relation to the driveshaft by only about 1 degree or so.

Thanks DirtDonk I’ll need to buy a angle finder tonight to calculate all my angles.

I finally broke down last month and bought one of those nifty little cube/square thingies. Lots of features and very handy.
I had been using my beam style home angle finder, but it wasn't as easy I don't think. It's always a little awkward, and sometimes a nice little metal square (what are they called? Angle square?) comes in handy for getting onto a flat surface.

Maybe others can share what they use for their particular angle finding tools with us?

Are you talking about something like this one?

i recently picked up a Wixey Digital Angle gauge based on a fellow CB member recommendation. Works great and easy to use. Helped me solve my pinion issues. $25 or so new on ebay.

There are free angle-finder apps for your phone as well, but probably only accurate to within 1-2 degrees since it relies on using the edge of your phone, which may not be totally straight. I guess it depends on the case/cover you have...mine work pretty well, but when I want to be as accurate as possible, I dig out the actual angle finder.

I've had one like you describe for about a year or so. Use it for all kinds of stuff in the shop and carry it with me on vessel commissioning trips to calibrate our AHRS units. Don't know how I lived without one...;D

There are angle finder app on iPhone

Are you talking about something like this one?

Yes. Exactly.
There are probably 100 different models and brands, so I just went down the list until I got blurry-eyed and then pressed add-to-cart.

As said, dunno how we got along so well without them!
Not being happy with the dial-type because most were cheaply built and not a very precise movement, I was an early adopter of digital readouts on the household beam-type. Bought my Craftsman many years ago and it just recently died on my. Without it I literally felt like my I just left my tool box on the side of the road!
Got online asap and nabbed one like you showed. Friend had one to check his Bronco's pinion angle and it looked like a handy design.

I have a couple of digital levels and angle finders. But I use this the most. It’s made for setting pitch on plane props but is easy to use and accurate to the 1/4 degree.

WHAAAT, no digital readout??? OLD SKOOL... ;D

I still don't have a digital mic or caliper in my shop... I could brag if my old stuff was Starrett but I just haven't updated...

You could print the picture and draw a line through center lines of the pinion and driveshaft. Measure with a protractor. $.49. The driveshaft does look too steep for the pinion. Simple fix.

Thanks y’all I just went ahead and bought a digital angle finder. I’ll report back here once I get all the angles measured.

I do this all the time to get measurements of odd items, except I don't bother printing. You can do it all digitally. Just stand back far enough so parallax doesn't affect the perspective of the angle or measurements.

 

[SSDDBRONCO]

Ok so I was able to get the angles of my pinion. Pictures are below for reference. If I didn’t put the angle finder in the proper area please let me know. Thanks

Driveshaft angle is 26.5
Pinion yoke angle is 12.2

Did you read the caption of the diagram I posted above?

Did you read the caption of the diagram I posted above?

Yes I did but I’m not quite sure if I’m doing my calculations correctly. If I only use rule #1 I get 3.37. So not sure if my math is correct?
