I appreciate you looking .... Im here in Southern California , New to this site . Im trying to add power steering. I looked at the pulley and there are no bolts for an accessory pulley. I cant access h series parts on dealer daily due to the fact that they were never sold here . Mine would be post 77 tilpre 06/80 .thinking a 2h would work , just dont know for sure.It helps if you put your location in your signature or post,then others know the conditions you are facing regarding parts.
Mentioning that are not sure about H engines ever having clutch fans also helps.
Are you trying to fit an aircon or power steering?
The parts diagram shows 2 types of crank pulley for the H . Pre 77 and post 77 to 80. What the difference is I dont know.
Some of the other toyota diesels have single pulley that bolts to the existing pulley to make a double or triple pulley. They have about 6 bolt holes on the crank pulley for this purpose.
If it doesnt,it maybe possible for a machinist to make something like that.
Had a look on MUD classifieds in the diesel section?
