The D2 (5U16805) that we just got back in operation with the guidance of the group in rebuilding the cooling system has been making some disconcerting noises, particularly at idle, that were coming from the generator. It has been decades since the electrical system was in service, so I'd rather just remove the generator than restore the full electrical system (head light, rear work light, starting engine starter).

It was too wet to work the fields so we pulled the generator Saturday and took it apart. The tail bearing had seized intermittently and spun the outer bearing race in the generator end cap, wearing quite a bit of clearance to the point that the armature and field windings would rub, which shifted a couple of the laminations out of line. The field windings, armature windings/core and commutator bar are all pretty well shot. I figure the best thing to do is just remove the generator and install a cover plate in its place. However for now I just pulled the drive gear (4F-3767 as I recall) and Woodruff key off the shaft and put a spring (from a weed-eater spool mechanism) that tightly gripped the shaft in it's place to hold the oil slingger cone in place, and reassembled and reinstalled the generator. I think that will do for now, but I'd like to just remove the generator altogether.

Is there a part number for a cover plate for the generator drive pad? If not, could someone tell me the part number for the gasket between the generator and the drive pad. I can then buy the gasket and use it to draw up a cover plate on my CAD system, and have it CNC waterjet cut from 1/2" steel plate (the mounting ears on the generator are 1/2" thick). I would be happy to post the drawing pdf and the DXF file read by most CNC cutting machines.

I have a request on another topic, could someone tell me the part number for the transmission dipstick?
I've just noticed a nick in the dipstick, which after thinking about it was probably there a long time but which I didn't take notice of until recently.

It's not a great photo, but you get the idea. I'm thinking if I put in a new one and don't see anything it was something that happened years ago. If the new one is scored then I ought to investigate. I need to change the transmission oil. It is a bit cloudy, not milky. I can't tell if it is a tiny bit of water getting in (it has been a very wet summer for SE Idaho, and the machine is only under cover in the winter), or maybe suspended wear particles. My recollection is that the transmission uses the same oil as the crankcase. If that is correct I'd use straight SAE 30 rather than the 5W-40 LE DELO 400 that I use in the crankcase. Can anyone confirm the oil spec and volume in the transmission?

I really appreciate the collective wisdom and wealth of data in this group.

There is no part number for the 3-bolt generator cover. You'd have to make one from a 6F8613 gasket pattern.

There is a Cat blank off plate 5F3162 and gasklet 5F3160 that replaces the generator mounting housing.

Dipstick/plunger for the transmission is a 4F7248

Your oil assumptions are not correct but I've given up on that discussion here. Transmission fill is 2 gallons.

Great, I've found the blank-off plate 5F3162, gasket 5F3160 and dipstick/plunger for the transmission 4F7248 using the machinery trader part number search feature and have them ordered and on the way.

Thanks,

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
