Every A Type Overdrive workshop manual I've seen mentions the hydraulic pressure test ( for example - TR4 spec: 380 - 400 PSI ) using this gauge set-up as a primary diagnostic indicator. This new, well made and unused gauge set allows the oil pressure generated by the overdrive oil pump to be known as the overdrive operates, either on a test stand or even better, while still mounted in the car, providing key diagnostic information about the overdrive unit for fault diagnosis and repair. Gauge: 304 stainless steel case, polycarbonate window, black-finished galvalume pointer, galvalume dial (white background with blue and black markings), brass movement, phosphor bronze bourdon tube. The allowable operating/ambient temperature range for the glycerin is -4F to 140F (-20C to 60C). The dampening action of the liquid also reduces pointer flutter and lubricates the internal parts of the gauge. 0 >600 PSI - 2 ½ inch diameter pressure Gauge - liquid (glycerin) filled, which helps absorb vibration and pressure spikes, increasing the service life of the gauge.įreightliner Fl70 Manual.Custom machined steel fitting to replace the operating valve plug.Without the correct oil pressure the overdrive will not function as it should. If your A or D type overdrive is not behaving properly, this primary diagnostic tool will help you identify and solve the problem.

Volvo spec laycock overdrive series#
When I started working on cars back in the 1970's, G元 was relatively new and now there is GL4 and GL5 all them hypoid oils.įrom what I understand, the basic hypoid oil is the same, but as the GL numbers get higher, there are more additives to better protect the internals.Īs a side note, I've read that some of the additives in the GL series can be harmful to brass and bronze parts like those inside most manual transmissions, IE synchros and bushings, so you SHOULD NOT USE THEM IN TRANSMISSIONS THAT DON'T SPECIFICALLY CALL FOR THEM!! Since Volvo made these cars, there have been improvements in hypoid gear oil. The diff does require hypoid gear oil, but the steering box does not.
