Cat Lift Trucks (& Caterpillar) T35D:
Oil for transmission.

Can anyone tell me what oil should be in the transmission of a 1972 Cat t35D.

The bellhousing has oil in it, is this supposed to be a wet system ?.

I'm waiting for the SERVICE SHOP REPAIR MANUAL to arrive for it, but it's going to be another fortnight before it arrives from the states (I'm in the UK).

Found the strainer, it was dirty and had specks of aluminium in amongst the dirt, cleaned it out and replaced it.

The transmission fluid was black, although obvious it had been red at some time, re-filled the transmission but the machine still wont move.

I hopeful it's the system that needs priming, can anyone tell me a way to do that with this particular truck

Thank you so much for the reply, I'll have a look for that filter (already got the parts manual so should be able to find it).

I removed the inspection plate at the top of the bellhousing and there is a thin plate held in place by three 17mm bolts, two were loose, the other is missing, any idea what that plate is for ?.

Check the strainer filter in the bottom of the transmission, they block and cause bell housing to fill with oil

In this week’s Forkliftaction News we look at two topics coming out of LogiMAT 2025 held in Stuttgart in March. The first was the large increase in exhibitors coming from China who are making it clear they have their sights set on markets outside of China (see story). The second is a closer look at what was the main theme of the trade show - the growing rise in automation, how it is changing the sector and how enthusiastically it is being embraced by younger generations...
