The vacuum pump is a vane-type pump which requires oil both to lubricate the vanes and, I believe, to seal the vanes against the housing. It's the same principle as the power steering pump.
The fault-finding is aimed more at defective alternators so if yours works fine (i.e. putting out about...
The oily thing on the back of the alternator is your vacuum pump. The O-ring part number is 90099-14055.
The slip ring surfaces look good, the worn grooves are from an oil seal I believe, and I don't think it's a replaceable part. The oil hole is in the part of the shaft which turns in a...
The FSM dictates how to set the pre-load on the valve body and then set the starting torque on the input shaft of the steering box, but this is a bench spec.
You won't damage the steering box by over-tightening the adjustment bolt for a short period. Long term, it might increase the rate of...
Thanks PG!
The dream is very much alive, unfortunately I don't have time to put all the rebuild details on the thread (the bulk of the time spent has been on the bodywork, welding, prepping and primer coating, which is still in progress) as I prefer to document the mechanical stuff where...
If you don't like fiddling with your truck then you should not consider adding an electronically controlled fuel pump installation.
Complete wiring loom change, addition of ECU and a host of other sensors. I'm not sure the the OHV 2LT ever got EFI, so potentially even worse than converting an...
I'm not sure about US lights, but for Japan/Euro lamps, Toyota sell (or did in 2022) the H1 type lamps (high beam only). I don't have the part number to hand right now. You can buy Koito (OEM) H4 lamps (dipped and high) from Japan, if you have someone there who can send them to you. Try Dave...
The following is based on long experience of ordering genuine parts from various suppliers.
Partsouq and Amayama's UAE warehouse sites show you stock levels (though Amayama's UAE stock levels have become very unreliable recently, something they say they are rectifying). Carmarka do not, which...
There is a plastic tab (which is part of the connector) which holds the terminal in place in the valley of the 'B' shape. The yellow lock plate pulls straight out, though it is not strictly necessary. With a thin metal pick, you pry the plastic tab away from the terminal. Ideally, you...
For de-scaling, I sealed up my engine's coolant passages and filled it for a few days with citric acid.
With your sheared stud, I would weld a bit of steel bar to it. When the stud is hot from welding, pour cold water over it, and it should wind straight out.
For removing those hard old paper...
Does anyone have a source for generic rubber and felt weatherstrip (the rubber itself) which is used on the door inner weatherstrips?
68170-90A01 is the Toyota part for the front windows with a single glass (i.e. no quarter ventilation window) and 'full' trim, i.e. a door card which comes up to...
Hi Matt!
The worm bearings are very much standard hi-cap tapered oller bearings - Koyo 30206JR or NSK 30230R - so no sweat getting those. I believe they also made them for some Toyota fork-lifts which can still be found on ebay with Toyota packaging and the -71 suffix on the part number. I...
