Hour meter

Hi Team,
the hour meter glass can be replaced easily--did plenty at The Dealer.
P/no's :- 1 x 2A5273--Glass and 2 x 4F8127Seals--both shown in Parts Book.

I found a new glass and the seals for a total $3.76 at an equipment parts supplier in Tennessee.

Push it out from inside?
Break it and clean out fragments before replacing?

Seems like both will require removing the plug in the end of the housing and sliding the mechanism out.

Hi Team,
scan below from a D6 SRB shows the type used at the time. Have reduced size of scan and it is a bit furry--may print clearer, if not I will redo it larger.
As CCJ said dismantle the unit and tap the glass out from inside with a stick or such if it is not broken.
Some had gaskets for the glass/plastic disc, and some did not--use suitable sealant--

To dismantle-to remove the counter assembly- first the drive gear housing must be removed--from memory.

Ensure that a drilling in the drive gear housing is pointing down when assembling the unit or the unit will fill with engine oil. This housing is a light press fit in the main body and can be removed by gripping the drive housing by using soft jaws in a vice and using a pulling & twisting motion, will come out fairly easily.

Cheers,
