As long as there's no Active Sulfur content, then clean oil is going to be better than old or no oil;)
Yes of course. The Castrol technical guru said there wasn't any Active Sulfur and it is safe for bronze, but who knows without getting it tested.

One would hope the technical department at Castrol would know exactly what is in there lubricants.
 
The donor 1.8 Freelander I picked up has already had the IRD removed, so would it be easier to drop the motor and gearbox as one unit rather than just taking off the gearbox?
 
Hello,

Sorry to jump in on this thread, but I've been trying to find someone with Freelander Gearbox knowledge.

I have a 1998 Freelander that I'm putting in a 1.8T engine in it. I'm currently trying to find the best way to manage this additional power (200 bhp) and torque (270 Nm) following a remap.

Is it best to keep the PG1 box and find a clutch that can take the upgrade (620 ti clutch), or use an L-Series gearbox, or use a Retrag gearbox....

In addition to this what bearings should I look to upgrade based on what box to keep!

Thanks in advance

Boxes for the FL1 are limited unless you go FWD (pointless imo). The L series Freelander box is rated to take the 177 Ftlb of torque as it the clutch. I seriously doubt it'll take 270 Nm very long. 270 Nm is 200 Ftlb in old money which is well above the long term capability of the K series bottom end anyway.
Getreg box won't fit.
So you're stuck with the standard 1.8 PG1 box which is rated at 121 Ftlb or the L series PG1 rated at 177 Ftlb, regeared to suit a petrol engine.

I thought the PG1 used in the L Series Freelander was the same spec, but differently geared and missing the diff, to the one used on Rover Tomcats with the T Series turbo 2.0l knocking out 200hp.

The L series box is known as a "high torque" box. It's designed to take 240Nm of torque. There's no diff, but there is a drop gear and a spline to take the drive to the IRD input shaft. ;)
 
You can upgrade the standard PG1 by replacing the plastic caged bearings with steel replacements- will be doing something similar later this year ;)

Thank you for this info.

Are there any Freelander kits out there as I understand the kits for the MG PG1 gear boxes either have additional bearing that are not all needed or are they slightly different?

Good question! Honest answer: I don’t know. My project is for an MG, but as far as I know, the Freelander PG1 internals are essentially the same.

An L-series box’s gearing can be changed by fitting the 1.8 gearset: the upgrades are largely bearings, but there are some differences in the journal sizes. You’ll have to do a search: there are some good Rover forums out there that cater for the tinkerer in all of us :)
 
Thankyou @rob_bell , over these last couple of weeks I've managed to pick up so much good knowledge. It's really good to see people out there are willing to help.

I think I'm going to go with the steel cage bearing upgrade on a PG1 gearbox. I'll see what info I can get from the earlier link to a chap who (I think) has used the MG ZT-T clutch.

I just count myself lucky that the K-series engine and PG1 gearbox are used in lots of different walks of life
