I've got a final drive sprocket bearing on my D6c that apears to need adjustment, and of course I don't have the special spanner tool used to tighten the bearing.
Looks like the tool is a 7F9306....is that correct?

Found a new one online for just under $300. For the few times I might need it that's plenty to invest.
Does anyone have a good backyard mechanic method of tightening the bearing without the proper tool?

Two men, two pry bars.

Bar seemed to get it tight.... Thanks

just curious, is there a torque spec for the sprocket bearing? or tolerance of movement?

- i'm more of a numbers guy...

The book says to use a 5' cheater bar and tighten it as tight as you can.

okay thanks Rusty....that sounds TIGHT!

yes that is tight--could be 1000 ft-lbs if you sat on the end of the bar

d4 6u the book say 1250ft/lb of torque on the outer spindle nut. ruff method 2 blokes, inch drive socket and bar, 6 foot of pipe and lean on it.
if you have a engineers black book you have the formula for calculating torque values according to handle length and force applied all you need is the formula, a spring balance scale and a method to apply said force.
a retired ships maintenance engineer showed me how to do it. he used it to do head bolts etc on big marine diesels without using the expensive hydraulic powered torque tools.

its simple really all your doing is shifting the point of measurement to the end of the lever instead of at the fastener.

otc tools make the c hook spanner and yes rather expensive. very simple tool though. i have considered making my own by getting the c hook laser cut out of 1/2 inch high strength steel plate such as bisalloy or strenx. which would cost less than the premade tool. i just havent got that far yet have to do the cad drawing first. better pull the finger out and do it.
