Power Steering Issues (1 Viewer)

Started work on the conversion to a G/M power steering pump today, removed the old Toyota pump and it's custom bracket that was made when I had the power steering added. Less said about that the better.

Pressed the mounting off the G/M pump for the pulley just leaving the shaft which is slightly bigger than the Toyota one. The G/M is a press fit without a keyway as opposed to the Toyota one. So I will machine the center out of the Toyota pulley to a press fit.

Another small hitch was the new bracket interfered with the Pacemaker extractors manifold plate, so out with the grinder just to shave a little off it. This won't be an issue when the new 2F-ETI goes in but due to a change of plan I need to fit it to the old 2F for a couple of months.

The holes for the genuine bracket were all full of $hit so I scrapped as much of the mud out as possible and washed out with WD 40 before re tapping them for the new bolts. Also fitted 2 new bolts to the water pump where the old bracket mounted.

With the bracket fitted the G/M pump needs to sit all the way back for the pulley be inline so I only require 2 spacers each 20mm to sit in front of the pump.

You can also see now how close the extractors are, but no great stress.

2x20mm Aluminum spacers in place


It lines up perfectly just the picture makes it look out of line.

Will have to make up some sort of dummy pulley to tension the water pump as I
don't have a smog pump.

Time to search

Went through the box of bits from the 3FE I had left over, more bits of bracket than you could poke a stick at

Found this adjustable tensioning pulley attached to a larger bracket, a bit of messing around untill I found which way it suited best. Need to make a spacer and a flat bar with 8mm holes to tie it in to the power steering bracket. Also needs a new bearing.

Ok spacer for the bottom mounting made, new bearing plus one spare, and a short strap to fix it to the power steering pump out of flat bar and

Just need to get the power steering cooler and reservoir now and connect it all up and see what we have

All done

Power steering reservoir is off a Mitsubishi Magna, the wreckers are full of them.

Belts fitted and tensioned

Power steering cooler in front of the radiator.

Results are great, at Idol it works perfect, far better than the Toyota pump that need a few revs even after a full rebuild

The G/M pump is 4 times cheaper than the Toyota pump to replace works better at Idol and hopefully does not leak ever time I give it a good work out off road, only time will tell their.

On the whole very good result.

First trip off road and all I can say is I'm stupid for not doing this 3 years ago.

If it's not right fix it don't put up with it, the G/M pump did not leak and works better at tick over with the tyre presure at 20 PSI.

We are at competition on the Nov 16,17&18 where we will be running 6 rear and 8 front PSI

This will be a reall test. For now one happy camper
