Hi all,
I have a 1988 Hj61 with the 12ht engine (5 speed manua)… this engine has the vacuum pump on the alternator which is driven off an oil feed line.
I am currently having issues (a heavy clutch and brake pedal) when idling or the revs are low.
I am wanting to do some troubleshooting before I spend money of a new alternator…
So far I have checked for leaks in the vacuum lines (as much as I can) - including spraying all connections with CRC Soft Seal which should seal up any small leak, I also removed the oil feed and return lines to ensure there are no blockages (all looks good).
I am wondering if the oil feed has a feed rate at idle (a certain amount of ml per minute???)
Also, what should the vacuum pressure (vacuum?) be at idle??
The alternator was new at the end of December and everything was working fine until a couple of weeks back when I noticed the heavy pedal of both clutch and brake….
Any thoughts or info would be greatly appreciated!!
Drew
