Gearbox Oil

Postby g259fsg » Wed Oct 10, 2012 4:37 pm

I wonder if members can tell me the best oil to use for refilling the gearbox on our 214 GSi? I'm about to replace the outer CV joints and need to pull the driveshafts. The workshop manual says to drain the gearbox first, so I'll need fresh oil.

Thanks,
Hugh

I think I just went for some stuff from GSF or eurocarparts of the right grade - I should have the bottle in the garage i'll go and check.

All is well with my gearbox after a drain and fill with it so should be ok......

Last time I researched this, I ended up tracking down some Castrol EPX 75W-80, with some difficulty, I should add.

A top-up to the correct level tranformed the feel of my old box. No need for a rebuild after all!

Thanks for the various replies. The reason for asking is that the official Rover workshop manual from the early 90s is quite specific about the gearbox oil. The following are specified for refill or top-up: Esso BV 75w/80w, Shell SF5288 75w/85w, Total BV 75w/85w and Unipart BV 75w/85w. It states the following oils may be used for topping-up only: BP Hypogear TL 75w/80w, Castrol EPX 75w/80w and Duckhams Hypoid PT 75w/80w. No explanation is given. I wonder if some oils affect the operation of the synchromesh. The Haynes manual talks about special gearbox oil (refer to your Rover Dealer), but again says it's OK to top-up Duckhams Hypoid 75w/80 GL-5.

Halfords have quite a lot of different gear oils including their own EP 75w/80 GL-4 . Quite a lot are now specified as universal Multigrade 75/90 GL-5 like the Syntrax stuff from Castrol.

I believe the Rover 200 uses a Peugeot gearbox. I wonder what they specify?

I mentioned I need to pull the driveshafts. Might see if I can do this without emptying the gearbox by stuffing a rag in the hole. Then I would only need to top-up.

Cheers,
Hugh

You don't need to pull the shafts to change the outer CV joints.

Simply release the shaft from the outer hub and knock the outer CV off with the inner still in the gearbox.

saves a lot of hassle!

Thanks very much for the tip, ETV. I was thinking of trying that now that I've got the suspension dismantled. Inner CVs seem OK, so as you say, I would only need to take the shaft out if the outer CVs won't budge.

Do you have any comments on the best gearbox oil?

Cheers,
Hugh

I wouldnt worry about specific brands of the gearbox oil. If its the right grade for general purpose Im sure its fine.

Most likely the reason for the specific type recommendation is purely that as the gearboxs are as you say Peugeot sourced, perhaps the spec that came from France for these and to meet the warranty needs were tose brands - Total in particular being French.

This far down the line it probably makes no difference. I would rather take this opportunity to completely drain and refill the gearbox, this will be much better for it than trying to preseve 15 year+ old gearbox oil.

As another example, service intervals on my Ford V8 engined MG ZT 260 are 5k with fully synthetic Castrol Edge 5W30. Thats totally over cautious and only like this because that was the terms under which Ford would warrant their engines when used in these cars apparently. These engines are massively under stressed and even stretching the service interval to nearer 10k the oil comes out pretty much as clean as when it went in

As above box oil of 75w80 should do the job. A box is more likely to die from not enough oil than the wrong type.

Most R65 boxes destroy the input shaft first of all. This is also the shaft that is highest up in the gearbox? Co-incidence?

Thanks for all the advice. I've now completed the job and have posted another thread with some things I found out.

Very good point from ETV about keeping the gearbox oil level topped up. I know I'm guilty of not checking it regularly. The WSM says it never needs to be changed and because it is awkward to get to, you probably forget to check the level. Even a slight oil leak over several years could make the level dangerously low.

Cheers,
Hugh
